computing.  
This manual tells how to set up and begin using your computer. It also  
provides detailed information on configuring your computer, basic  
operations and care, using optional devices and troubleshooting.  
Conventions  
This manual uses the following formats to describe, identify, and highlight  
terms and operating procedures.  
Abbreviations  
On first appearance, and whenever necessary for clarity, abbreviations are  
enclosed in parentheses following their definition. For example: Read Only  
Memory (ROM). Acronyms are also defined in the Glossary.  
Icons  
Icons identify ports, dials, and other parts of your computer. The indicator  
panel also uses icons to identify the components it is providing information

Keys  
The keyboard keys are used in the text to describe many computer  
operations. A distinctive typeface identifies the key top symbols as they  
appear on the keyboard. For example, ENTER identifies the ENTER key.  
Key operation  
Some operations require you to simultaneously use two or more keys. We  
identify such operations by the key top symbols separated by a plus sign  
(+). For example, CTRL + C means you must hold down CTRL and at the  
same time press C. If three keys are used, hold down the first two and at  
the same time press the third.  
ABC  
When procedures require an action such as  
clicking an icon or entering text, the icon's name or  
the text you are to type in is represented in the  
typeface you see to the left.

General Precautions  
TOSHIBA computers are designed to optimize safety, minimize strain and  
withstand the rigors of portability. However, certain precautions should be  
observed to further reduce the risk of personal injury or damage to the  
computer.  
Be certain to read the general precautions below and to note the cautions  
included in the text of the manual.  
Provide adequate ventilation  
Always make sure your computer and AC adaptor have adequate  
ventilation and are protected from overheating when the power is turned on  
or when an AC adaptor is connected to a power outlet (even if your  
computer is in Sleep Mode). In this condition, observe the following:  
Never cover your computer or AC adaptor with any object.  
Never place your computer or AC adaptor near a heat source, such as  
an electric blanket or heater.  
Never cover or block the air vents including those located at the base  
of the computer.  
Always operate your computer on a hard flat surface. Using your  
computer on a carpet or other soft material can block the vents.  
Always provide sufficient space around the computer.  
Overheating your computer or AC adaptor could cause system failure,  
computer or AC adaptor damage or a fire, possibly resulting in serious  
injury.  
Creating a computer-friendly environment  
Place the computer on a flat surface that is large enough for the computer  
and any other items you are using, such as a printer.  
Leave enough space around the computer and other equipment to provide  
adequate ventilation. Otherwise, they may overheat.  
To keep your computer in prime operating condition, protect your work area  
from:  
Dust, moisture, and direct sunlight.  
Equipment that generates a strong electromagnetic field, such as  
stereo speakers (other than speakers that are connected to the  
computer) or speakerphones.  
Rapid changes in temperature or humidity and sources of temperature  
change such as air conditioner vents or heaters.  
Extreme heat, cold, or humidity.  
Liquids and corrosive chemicals.

C850/C850D/L850/L850D  
Stress injury  
Carefully read the Instruction Manual for Safety and Comfort. It contains  
information on the prevention of stress injuries to your hands and wrists  
that can be caused by extensive keyboard use. It also includes information  
on work space design, posture and lighting that can help reduce physical  
stress.  
Heat injury  
Avoid prolonged physical contact with the computer. If the computer is  
used for long periods, its surface can become very warm. While the  
temperature will not feel hot to the touch, if you maintain physical  
contact with the computer for a long time, for example if you rest the  
computer on your lap or if you keep your hands on the palm rest, your  
skin might suffer a low-heat injury.  
If the computer has been used for a long time, avoid direct contact  
with the metal plate supporting the various interface ports as this can  
become hot.  
The surface of the AC adaptor can become hot when in use but this  
condition does not indicate a malfunction. If you need to transport the  
AC adaptor, you should disconnect it and let it cool before moving it.  
Do not lay the AC adaptor on a material that is sensitive to heat as the  
material could become damaged.  
Pressure or impact damage  
Do not apply heavy pressure to the computer or subject it to any form of  
strong impact as this can damage the computer's components or otherwise  
cause it to malfunction.  
Mobile phones  
Please be aware that the use of mobile phones can interfere with the audio  
system. The operation of the computer will not be impaired in any way, but  
it is recommended that a minimum distance of 30cm is maintained between  
the computer and a mobile phone that is in use.  
Instruction Manual for Safety and Comfort  
All important information on the safe and proper use of this computer is  
described in the enclosed Instruction Manual for Safety and Comfort. Be  
sure to read it before using the computer.

You may not have all the software listed above depending on the model  
you purchased.  
Getting Started  
All users should be sure to read the section Starting up for the first  
time.  
Be sure to read the enclosed Instruction Manual for Safety and  
Comfort for information on the safe and proper use of this computer. It  
is intended to help you be more comfortable and productive while  
using a notebook computer. By following the recommendations in it  
you may reduce your chance of developing a painful or disabling injury  
to your hand, arms, shoulders or neck.  
This section provides basic information to start using your computer. It  
covers the following topics:  
Connecting the AC adaptor  
Opening the display  
Turning on the power  
Starting up for the first time  
Turning off the power  
Restarting the computer  
Use a virus-check program and make sure it is updated regularly.  
Never format storage media without checking its content - formatting  
destroys all stored data.  
It is a good idea to periodically back up the internal Hard Disk Drive or  
other main storage device to external media. General storage media is  
not durable or stable over long periods of time and under certain  
conditions may result in data loss.  
Before you install a device or application, save any data in memory to  
the Hard Disk Drive or other storage media. Failure to do so may  
result in the loss of data.

C850/C850D/L850/L850D  
Connecting the AC adaptor  
Attach the AC adaptor when you need to charge the battery or you want to  
operate from AC power. It is also the fastest way to get started, because  
the battery pack will need to be charged before you can operate from  
battery power.  
The AC adaptor can automatically adjust to any voltage ranging from 100  
to 240 volts and to a frequency of either 50 or 60 hertz, enabling you to use  
this computer in almost any country/region. The adaptor converts AC  
power to DC power and reduces the voltage supplied to this computer.  
Always use the TOSHIBA AC adaptor that was included with your  
computer, or use AC adaptors specified by TOSHIBA to avoid any risk  
of fire or other damage to the computer. Use of an incompatible AC  
adaptor could cause fire or damage to the computer possibly resulting  
in serious injury. TOSHIBA assumes no liability for any damage  
caused by use of an incompatible adaptor.  
Never plug the AC adaptor into a power source that does not  
correspond to both the voltage and the frequency specified on the  
regulatory label of the unit. Failure to do so could result in a fire or  
electric shock, possibly resulting in serious injury.  
Always use or purchase power cables that comply with the legal  
voltage and frequency specifications and requirements in the country  
of use. Failure to do so could result in a fire or electric shock, possibly  
resulting in serious injury.  
The supplied power cord conforms to safety rules and regulations in  
the region the product is bought and should not be used outside this  
region. For use in other regions, please buy power cords that conform  
to safety rules and regulations in the particular region.  
Do not use a 3-pin to 2-pin conversion plug.  
When you connect the AC adaptor to the computer, always follow the  
steps in the exact order as described in the User’s Manual.  
Connecting the power cable to a live electrical outlet should be the last  
step otherwise the adaptor DC output plug could hold an electrical  
charge and cause an electrical shock or minor bodily injury when  
touched. As a general safety precaution, avoid touching any metal  
parts.  
Never place your computer or AC adaptor on a wooden surface,  
furniture, or any other surface that could be marred by exposure to  
heat since the computer base and AC adaptor's surface increase in  
temperature during normal use.  
Always place your computer or AC adaptor on a flat and hard surface  
that is resistant to heat damage.  
Refer to the enclosed Instruction Manual for Safety and Comfort for  
detailed precautions and handling instructions.

Sleep Mode  
If you have to interrupt your work, you are able to turn off the power without  
exiting from your software by placing the computer into Sleep Mode. In this  
mode data is maintained in the computer's main memory so that when you  
turn on the power again, you can continue working right where you left off.  
When you have to turn off your computer aboard an aircraft or in places  
where electronic devices are regulated or controlled, always completely  
shut down the computer. This includes turning off any wireless  
communication functionalities, and cancelling settings that reactivate the  
computer automatically, such as a timer recording function. Failure to  
completely shut down the computer in this way could allow the operating  
system to reactivate and run pre-programmed tasks or preserve unsaved  
data, which could interfere with aviation or other systems, possibly causing  
serious injury.  
Before entering Sleep Mode, be sure to save your data.  
When the AC adaptor is connected, the computer will go into Sleep  
Mode according to the settings in the Power Options (to access it,  
Start -> Control Panel -> System and Security -> Power Options).  
To restore the operation of the computer from Sleep Mode, press and  
hold the power button or any key on the keyboard for a short amount  
of time. Please note that keyboard keys can only be used if the Wake-  
up on Keyboard option is enabled within the HW Setup utility.

The number of keys available on your keyboard will depend on which  
country/region your computer is configured for, with keyboards being  
available for numerous languages.  
In use there are different types of keys, specifically typewriter keys,  
function keys, soft keys, Hot keys and Windows special keys.  
Never remove the key caps on your keyboard. Doing so could cause  
damage to the parts under the key caps.  
Keyboard indicators  
The following figure shows the position of the CAPS LOCK indicator and  
the NUM LOCK indicator which show the following conditions:  
When the CAPS LOCK indicator glows, the keyboard will produce  
capitals when any letter is typed.  
When the NUM LOCK indicator glows, the ten key allows you to enter  
numbers.

entry.  
Function keys: F1 … F12  
The function keys (not to be confused with the special FN key) are the  
twelve keys at the top of your keyboard - these keys function differently  
from other keys.  
F1 through F12 are called function keys because they execute  
programmed functions when pressed and, when used in combination with  
the FN key, those keys marked with icons also execute specific functions  
on the computer.

1. Laser lens  
When the disc tray is fully opened, the edge of the computer will cover the  
disc tray slightly. Therefore, you will need to turn the disc at an angle when  
you place it in the disc tray. After seating the disc, however, make sure it  
lies flat.  
Do not touch the laser lens or any portion of its surrounding casing as  
this could cause misalignment.  
Prevent foreign objects from entering the drive. Check the surface of  
the disc tray, especially the area behind the front edge of the disc tray,  
to make sure there are no such objects before closing the drive.  
4. Press gently at the center of the disc until you feel it click into place.  
The disc should lie below the top of the spindle, flush with the spindle  
base.  
5. Push the center of the disc tray to close it. Press gently until it locks  
into place.  
If the disc is not seated properly when the disc tray is closed, the disc might  
be damaged. Also, the disc tray might not open fully when you press the  
eject button.  
Removing discs  
To remove the disc, follow the steps as detailed below:  
Do not press the eject button while the computer is accessing the optical  
disc drive. Wait for the optical disc drive indicator to go out before you open  
the disc tray. Also, if the disc is spinning when you open the disc tray, wait  
for it to stop before you remove it.

the disc tray out until it is fully opened.  
When the disc tray pops open slightly, wait a moment to make sure the  
disc has stopped spinning before pulling the disc tray fully open.  
2. The disc extends slightly over the sides of the disc tray so you can  
grasp it. Gently lift out the disc.  
3. Push the center of the disc tray to close it. Press gently until it locks  
into place.  
How to remove disc when the disc tray will not open  
Pressing the eject button will not open the disc tray when the computer

You can use the DVD Super Multi drive or Blu-ray™ Combo drive to write  
data to either CD-R, CD-RW, DVD-R, DVD-R DL, DVD-RW, DVD+R, DVD  
+R DL, DVD+RW or DVD-RAM discs.  
You can use the Blu-ray™ Writer drive to write data to either CD-R, CD-  
RW, DVD-R, DVD-R DL, DVD-RW, DVD+R, DVD+R DL, DVD+RW, DVD-  
RAM, BD-R, BD-R DL, BD-RE or BD-RE DL discs.

RE TL discs.  
When writing information to media using an optical drive, you should  
always ensure that you connect the AC adaptor to a live power socket. It is  
possible that, if data is written while powered by the battery pack, the write  
process may sometimes fail due to low battery power - in these instances  
data loss may occur.  
Important message  
Before you write or rewrite to any of the media supported by the optical  
disc drive, please read and follow all of the setup and operating instructions  
in this section. If you fail to do so, you may find that the optical disc drive  
may not function properly, and you may fail to write or rewrite information  
successfully - this may cause you to either lose data or incur other damage  
to the drive or media.

radio that may either absorb or reflect the radio signal.  
Bluetooth wireless technology  
Some computers in this series have Bluetooth wireless communication  
function which eliminates the need for cables between electronic devices  
such as computers, printers and mobile phones. When it is enabled,  
Bluetooth provides the wireless personal area network environment which  
is safe and trustworthy, that is quick and easy.  
You cannot use the computer's built-in Bluetooth functions and an external  
Bluetooth adaptor simultaneously. For reference, Bluetooth wireless  
technology has the following features:  
Worldwide operation  
The Bluetooth radio transmitter and receiver operate in the 2.4GHz band,  
which is license-free and compatible with radio systems in most countries  
in the world.  
Radio links  
You can easily establish links between two or more devices, with these  
links being maintained even if the devices are not within a line-of-sight of  
each other.  
Security  
Two advanced security mechanisms ensure a high level of security:  
Authentication prevents access to critical data and makes it impossible  
to falsify the origin of a message.  
Encryption prevents eavesdropping and maintains link privacy.

Memory media format  
New media cards are formatted according to specific standards. If you wish  
to reformat a media card, be sure to do so with a device that uses media  
cards.  
Formatting a memory media card  
Memory media cards are sold already formatted in conformity to specific  
standards. If you reformat a memory card, be sure to reformat it with a  
device such as digital camera or digital audio player that uses the memory  
cards, not with the format command provided within Windows.  
Should you need to format all areas of the memory card, including the  
protected area, you will need to obtain an appropriate application that  
applies the copy protection system.  
Media care  
Observe the following precautions when handling the card.  
Do not twist or bend cards.  
Do not expose cards to liquids or store in humid areas or lay media  
close to containers of liquid.  
Do not touch the metal part of a card or expose it to liquids or let it get  
dirty.  
After using card, return it to its case.  
The card is designed so that it can be inserted only one way. Do not  
try to force the card into the slot.  
Do not leave a card partially inserted in the slot. Press the card until  
you hear it click into place.  
Set the write-protect switch to the lock position, if you do not want to  
record data.

Moving the computer  
While the computer is designed for flexible day-to-day usage you should  
exercise a few simple precautions when moving it in order to help ensure  
trouble-free operation.  
Make sure all disk/disc activity has ended before moving the  
computer.  
Turn off (shut down) the computer.  
Disconnect the AC adaptor and all peripherals before moving the  
computer.  
Close the display panel.  
Do not pick up the computer by its display panel.  
Before carrying your computer, shut it down, disconnect the AC  
adaptor and allow it to cool down - a failure to follow this instruction  
may result in minor heat injury.  
Be careful not to subject the computer to impact or shock - a failure to  
follow this instruction could result in damage to computer, computer  
failure or loss of data.  
Never transport your computer with any cards installed - this may  
cause damage to either the computer and/or the card resulting in  
product failure.  
Always use a suitable carry case when transporting the computer.  
When carrying your computer, be sure to hold it securely so that it  
does not fall or hit anything.  
Do not carry your computer by holding any of its protruding elements.  
Heat dispersal  
To protect against overheating, the processor is equipped with an internal  
temperature sensor which activates a cooling fan or lowers the processing  
speed if the computer's internal temperature rises to a certain level. You  
are able to select whether to control this temperature by either turning on  
the fan first, then if necessary lowering the processor speed, or by lowering  
the processor speed first, then if necessary turning on the fan. Both of  
these functions are controlled through the Power Options.  
When the processor's temperature falls within normal range, the fan will be  
turned off and the processor operation returned to its standard speed.  
If the processor's temperature reaches an unacceptably high level with  
either setting, the computer automatically shuts down to prevent any  
damage. In this instance all unsaved data in memory will be lost.

C850/C850D/L850/L850D  
When Sleep and Charge function is enabled, USB bus power (DC5V)  
will be supplied to compatible ports even when the power of the  
computer is turned OFF. USB bus power (DC5V) is similarly supplied  
to the external devices which are connected to the compatible ports.  
However, some external devices cannot be charged solely by  
supplying USB bus power (DC5V). As for the specifications of the  
external devices, please contact the device manufacturer or check the  
specifications of the external devices thoroughly before use.  
Using the sleep and charge function to charge external devices will  
take longer than charging the devices with their own chargers.  
If Sleep and Charge function is enabled, the computer’s battery will  
discharge during hibernation or when the computer is turned off. It is  
recommended that you connect the AC adaptor to the computer when  
enabling the Sleep and Charge function.  
External devices connected to the USB bus power (DC5V) function  
that interfaces with the power ON/OFF of the computer may always be  
in an operational state.  
When there is a current overflow of the external devices connected to  
the compatible ports, USB bus power (DC5V) supply may be stopped  
for safety reasons.  
When Sleep and Charge function is enabled, the USB Wakeup  
function does not work for compatible ports. In that case, if there is a  
USB port that does not have the Sleep and Charge function, attach  
the mouse or keyboard to it. If all USB ports have the Sleep and  
Charge function, change to disable Sleep and Charge function. The  
USB Wakeup function will now work, but the Sleep and Charge  
function will be disabled.  
Metal paper clips or hair pins/clips will generate heat if they come into  
contact with USB ports. Do not allow USB ports to come into contact with  
metal products, for example when carrying the computer in your bag.  
Starting the TOSHIBA Sleep Utility

Power supply mode settings  
Your PC has multiple charging modes so that many different USB devices  
can be supported for Sleep and Charge function. Auto Mode (Default) is  
suitable for a wide range of digital audio players.  
However, determining which mode is suitable for your USB device is  
unknown without trying. Try each mode, using the following procedure,  
from Auto Mode to Alternate Mode to find the suitable mode for your USB  
device to charge.  
This function may not be able to be used with some connected external  
devices even if the appropriate mode is selected. In this situation, clear the  
"Enable Sleep and Charge" check box and stop using this function.  
Battery Settings  
This utility can be used to specify the lower limit of remaining battery life for  
Sleep and Charge. Move the slider bar to specify the lower limit. If the  
remaining battery life falls below the setting, the Sleep and Charge function  
will be stopped. Clearing the "Enable under Battery Mode" check box sets  
the utility to only charge when the AC adaptor is connected.

C850/C850D/L850/L850D  
Battery  
This section explains battery types, use, recharging methods and handling.  
Battery types  
The computer has different types of batteries.  
Battery pack  
When the AC adaptor is not connected, the computer's main power source  
is a removable lithium ion battery pack, also referred to in this manual as  
the main battery. You can purchase additional battery packs for extended  
use of the computer away from an AC power source although you should  
not change the battery pack while the AC adaptor is connected.  
Before you remove the battery pack, save your data and shut down the  
computer, or place the computer into Hibernation Mode. Please be aware  
that, when placing the computer into Hibernation Mode, the contents of  
memory will be saved to the hard disk drive, although for safety sake, it is  
best to also save your data manually.  
Real Time Clock (RTC) battery  
The Real Time Clock (RTC) battery provides power for the internal real  
time clock and calendar function and also maintains the system  
configuration while the computer is turned off. If the RTC battery becomes  
completely discharged, the system will lose this information and the real  
time clock and calendar will stop working.  
You can change the Real Time Clock settings in the BIOS setup utility. To  
access it, press and hold the F2 key, and then turn on the computer - the  
BIOS setup utility will load. Please refer to Chapter 6 Troubleshooting for  
further information.  
Care and use of the battery pack  
This section provides the important safety precautions in order to handle  
your battery pack properly.  
Refer to the enclosed Instruction Manual for Safety and Comfort for  
detailed precautions and handling instructions.  
Make sure the battery is securely installed in the computer before  
attempting to charge the battery pack. Improper installation could  
generate smoke or fire, or cause the battery pack to rupture.  
Keep the battery pack out of reach of infants and children. It can  
cause injury.

C850/C850D/L850/L850D  
The lithium ion battery pack can explode if not replaced, used,  
handled or disposed of properly. Dispose of the battery as required by  
local ordinances or regulations. Use only batteries recommended by  
TOSHIBA as replacements.  
The computer's RTC battery is a lithium battery and should be  
replaced only by your dealer or by a TOSHIBA service representative.  
The battery can explode if not properly replaced, used, handled or  
disposed. Dispose of the battery as required by local ordinances or  
regulations.  
Charge the battery pack only in an ambient temperature between 5  
and 35 degrees Celsius. Otherwise, the electrolyte solution might leak,  
battery pack performance might deteriorate and the battery life might  
be shortened.  
Never install or remove the battery pack without first turning off the  
power and disconnecting the AC adaptor. Never remove the battery  
pack while the computer is in Sleep Mode. Data could be lost.  
Never remove the battery pack while the Wake-up on LAN function is  
enabled. Data will be lost. Before you remove a battery pack, disable the  
Wake-up on LAN function.  
Charging the batteries  
When the power in the battery pack becomes low, the DC IN/Battery  
indicator will flash amber to indicate that only a few minutes of battery  
power remain. If you continue to use the computer while the DC IN/Battery  
indicator flashes, the computer will enable Hibernation Mode so that you do  
not lose any data, and automatically turn itself off.  
You must recharge a battery pack when it becomes discharged.  
Procedures  
To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack  
and plug the other end into a working outlet - the DC IN/Battery indicator  
will glow amber while the battery is being charged.  
Use only the computer connected to an AC power source or optional  
TOSHIBA Battery charger to charge the battery pack. Never attempt to  
charge the battery pack with any other charger.  
Charging Time  
The following table shows the approximate time required to fully charge a  
discharged battery.

Please be aware that the charging time when the computer is on is affected  
by ambient temperature, the temperature of the computer and how you are  
using the computer - if you make heavy use of external devices for  
example, the battery might scarcely charge at all during operation.  
Battery charging notice  
The battery may not begin charging immediately under the following  
conditions:  
The battery is extremely hot or cold (if the battery is extremely hot, it  
might not charge at all). To ensure the battery charges to its full  
capacity, you should charge it at room temperature of between 5°C to  
35°C (41°F to 95°F).  
The battery is nearly completely discharged. In this instance you  
should leave the AC adaptor connected for a few minutes and the  
battery should begin charging.  
The DC IN/Battery indicator may show a rapid decrease in battery  
operating time when you try to charge a battery under the following  
conditions:  
The battery has not been used for a long time.  
The battery has completely discharged and been left in the computer  
for a long time.  
In such cases you should follow the steps as detailed below:  
1. Fully discharge the battery by leaving it in the computer with the power  
on until the system automatically turns itself off.  
2. Connect the AC adaptor to the DC IN 19V jack of the computer, and to  
a wall outlet that is supplying power.  
3. Charge the battery until the DC IN/Battery indicator glows white.  
Repeat these steps two or three times until the battery recovers normal  
capacity.  
Monitoring battery capacity  
Remaining battery power can be monitored using the following methods.  
User's Manual

5-5  
 
C850/C850D/L850/L850D  
Clicking the battery icon on the Taskbar  
Via the Battery Status in the Windows Mobility Center window  
You should wait at least 16 seconds after turning on the computer  
before trying to monitor the remaining operating time. This is because  
the computer needs this time to check the battery's remaining capacity  
and then calculate the remaining operating time, based on this  
together with the current power consumption.  
Please be aware that the actual remaining operating time may differ  
slightly from the calculated time.  
With repeated discharges and recharges, the battery's capacity will  
gradually decrease. In view of this it will be noted that an often used,  
older battery will not operate for as long as a new battery even when  
both are fully charged.  
Maximizing battery operating time  
A battery's usefulness depends on how long it can supply power on a  
single charge, while how long the charge lasts in a battery depends on:  
Processor speed  
Screen brightness  
System Sleep Mode  
System Hibernation Mode  
Display power off period  
Hard Disk Drive power off period  
How often and for how long you use the Hard Disk Drive and external  
disk(c) drives, for example, optical disc.  
How much charge the battery contained to begin with.  
How you use optional devices, such as a USB device, to which the  
battery supplies power.  
Whether you enable Sleep Mode, which can conserve battery power if  
you are frequently turning the computer off and on.  
Where you store your programs and data.  
Whether you close the display panel when you are not using the  
keyboard - closing the display saves power.  
The environmental temperature - operating time decreases at low  
temperatures.  
Whether you enable Sleep and Charge function.  
The condition of the battery terminals - you should always ensure the  
terminals stay clean by wiping them with a clean dry cloth before  
installing the battery pack.  
Batteries exhausted time  
When you turn off the power of your computer with batteries fully charged,  
the batteries will be exhausted within the following approximate period.

Extending battery life  
To maximize the life of your battery packs:  
At least once a month, disconnect the computer from a power source  
and operate it on battery power until the battery pack fully discharges.  
Before doing so, follow the steps as detailed below.  
1. Turn off the computer's power.  
2. Disconnect the AC adaptor and turn on the computer's power - if it  
does not turn on then go to Step 4.  
3. Operate the computer on battery power for five minutes. If you find  
that the battery pack has at least five minutes of operating time,  
continue operating until the battery pack is fully discharged, however, if  
the DC IN/Battery indicator flashes or there is some other warning to  
indicate a low battery condition, go to Step 4.  
4. Connect the AC adaptor to the DC IN 19V jack of the computer, and  
to a wall outlet that is supplying power. The DC IN/Battery indicator  
should glow amber to indicate that the battery pack is being charged,  
however, in the event that DC IN/Battery indicator does not glow this  
indicates that power is not being supplied - check the connections for  
the AC adaptor and the power cord.  
5. Charge the battery pack until the DC IN/Battery indicator glows  
white.  
If you have extra battery packs, rotate their use.  
If you will not be using the system for an extended period, for example  
for more than one month, remove the battery pack from the computer.  
Store spare battery packs in a cool dry place out of direct sunlight.  
Replacing the battery pack  
Please be aware that the battery pack is classified as a consumable item.

Troubleshooting  
TOSHIBA have designed this computer for durability, however, should  
problems occur you are able to use the procedures detailed in this chapter  
to help determine the cause.  
All users should become familiar with this chapter as knowing what might  
go wrong can help prevent problems from occurring in the first place.  
Problem solving process  
Resolving problems will be much easier if you observe the following  
guidelines:  
Stop immediately when you recognize a problem exists as taking  
further action may result in data loss or damage, or you may destroy  
valuable problem related information that can help solve the problem.  
Observe what is happening - write down what the system is doing and  
what actions you performed immediately before the problem occurred.  
Make a screenshot of the current display.  
Please also be aware that the questions and procedures described in this  
chapter are meant only as a guide, they are not definitive problem solving  
techniques. In reality many problems can be solved simply, but a few may  
require help from TOSHIBA Support - if you find you need to consult  
others, be prepared to describe the problem in as much detail as possible.  
Preliminary checklist  
You should always consider the simplest solution first - the items detailed  
in this checklist are easy to fix and yet can cause what appears to be a  
serious problem:  
Make sure you turn on all peripheral devices before you turn on the  
computer - this includes your printer and any other external device you  
are using.  
Before you attach an external device you should first turn the  
computer off, then when you turn the computer back on again it will  
recognize the new device.  
Make sure all optional accessories are configured properly in the  
computer's setup program and that all required driver software has  
been loaded (please refer to the documentation included with the  
optional accessories for further information on its installation and  
configuration).

Check all cables to ensure they are correctly and firmly attached to the  
computer - loose cables can cause signal errors.  
Inspect all connecting cables for loose wires and all connectors for  
loose pins.  
Check that your disc media is correctly loaded  
Always try to make detailed notes of your observations and keep them in a  
permanent error log - this will help you to describe your problems to  
TOSHIBA Support. In addition, if a problem recurs, the log you have made  
will help to identify the problem faster.  
Analyzing the problem  
Sometimes the computer will give you clues that can help you identify why  
it is malfunctioning. In view of this you should keep the following questions  
in mind:  
Which part of the computer is not operating properly - keyboard, Hard  
Disk Drive, display panel, Touch Pad, Touch Pad control buttons - as  
each device will produce different symptoms.  
Check the options within the operating system to ensure that its  
configuration is set properly.  
What appears on the display? Does it display any messages or  
random characters? Make a screenshot of the current display and, if  
possible, look up the messages in the documentation included with the  
computer, software or operating system.  
Check that all connecting cables are correctly and firmly attached as  
loose cables can cause erroneous or intermittent signals.  
Do any indicators light, if so, which ones, what color are they and do  
they stay on or blink? Write down what you see.  
Do you hear any beeps, if so how many, are they long or short and are  
they high pitched or low pitched? In addition, is the computer making  
any unusual noises? Write down what you hear.  
Record your observations so you can describe them in detail to TOSHIBA

The problems may be caused by your software  
or disk. If you cannot load a software package,  
the media may be damaged or the program  
might be corrupted - in these instances try  
loading another copy of the software if possible.  
If an error message appears while you are using  
a software package you should refer to the  
documentation supplied with it as this will usually  
include a problem solving section or a summary  
of error messages.  
Next, you should check any error messages  
against the operating system documentation.

Hardware  
If you cannot find a software problem, you should  
then check the setup and configuration of your  
hardware. First run through the items in the  
preliminary checklist as described previously  
then, if you still cannot correct the problem, try to  
identify the source - the next section provides  
checklists for individual components and  
peripherals.  
Before using a peripheral device or application software that is not an  
authorized TOSHIBA part or product, make sure the device or software can  
be used with your computer. Use of incompatible devices may cause injury  
or may damage your computer.  
If something goes wrong  
Your program stops responding  
If you are working with a program that suddenly freezes all operations,  
chances are the program has stopped responding. You can exit the failed  
program without shutting down the operating system or closing other  
programs.  
To close a program that has stopped responding:  
1. Press CTRL, ALT, and DEL simultaneously (once), then click Start  
Task Manager. The Windows® Task Manager window appears.  
2. Click the Applications tab. If a program has stopped responding, the  
words "not responding" appear beside its name in the list.  
3. Select the program you want to close, then click End Task. Closing  
the failed program should allow you to continue working. If it does not,  
continue with the next step.  
4. Close the remaining programs one by one by selecting the program  
name, then End Task. Closing all programs should allow you to  
continue working. If it does not, power off your computer and then  
restart it.

Make sure you attached the AC adaptor and power cord/cable properly.  
If you are using the AC adaptor, check that the wall outlet is working by  
plugging in another device, such as a lamp.  
Verify that the computer is on by looking at the ON/OFF indicator.  
If the indicator is glowing, the computer is on. Also, try turning the computer  
off and then on.

that the power outlet the AC adaptor is connected  
to its supplying power - this can be tested by  
plugging another appliance into it.  
Check whether the battery is hot or cold to the  
touch - if so, it will not charge properly and should  
be allowed to reach room temperature before you  
try again.  
Unplug the AC adaptor and remove the battery to  
make sure its connecting terminals are clean - if  
necessary wipe them with a soft dry cloth lightly  
dipped in alcohol.  
Connect the AC adaptor and replace the battery,  
taking care to ensure that it is securely seated in  
the computer.  
Check the DC IN/Battery indicator - if it does not  
glow, allow the computer to charge the battery for  
at least twenty minutes. If the DC IN/Battery  
indicator starts to glow after this period, allow the  
battery to continue to charge for at least another  
twenty minutes before turning on the computer.  
However, if the indicator still does not glow, the  
battery may be at the end of its operating life and  
should be replaced. However, if you do not believe  
the battery is at the end of its operating life, you  
should speak to TOSHIBA Support.

Legal Footnotes  
This chapter states the Legal Footnotes information applicable to TOSHIBA  
computers.  
Non-applicable Icons  
Certain computer chassis are designed to accommodate all possible  
configurations for an entire product series. Therefore, please be aware that  
your selected model may not have all the features and specifications  
corresponding to all of the icons or switches shown on the computer  
chassis.  
CPU  
Central Processing Unit (CPU) Performance Legal Footnotes.  
CPU performance in your computer product may vary from specifications  
under the following conditions:  
use of certain external peripheral products  
use of battery power instead of AC power  
use of certain multimedia, computer generated graphics or video  
applications  
use of standard telephone lines or low speed network connections  
use of complex modeling software, such as high end computer aided  
design applications  
use of several applications or functionalities simultaneously  
use of computer in areas with low air pressure (high altitude >1,000  
meters or >3,280 feet above sea level)  
use of computer at temperatures outside the range of 5°C to 30°C  
(41°F to 86°F) or >25°C (77°F) at high altitude (all temperature  
references are approximate and may vary depending on the specific  
computer model - please refer to your computer documentation or visit  
the TOSHIBA website at www.pcsupport.toshiba.com for details).  
CPU performance may also vary from specifications due to design  
configuration.  
Under some conditions, your computer product may automatically shut-  
down. This is a normal protective feature designed to reduce the risk of lost  
data or damage to the product when used outside recommended  
conditions. To avoid risk of lost data, always make back-up copies of data  
by periodically storing it on an external storage medium. For optimum  
performance, use your computer product only under recommended

conditions. Read additional restrictions in your product documentation.  
Contact TOSHIBA technical service and support, refer to TOSHIBA support  
section in Chapter 6, Troubleshooting for more information.  
64-Bit Computing  
64-bit processors are designed to take advantage of 32 and 64 bit  
computing.  
64-bit computing requires that the following hardware and software  
requirements are met:  
64-bit Operating System  
64-bit CPU, Chipset and BIOS (Basic Input/Output System)  
64-bit Device drivers  
64-bit applications  
Certain device drivers and/or applications may not be compatible with a 64-  
bit CPU and therefore may not function properly.  
Memory (Main System)  
Part of the main system memory may be used by the graphics system for  
graphics performance and therefore reduce the amount of main system  
memory available for other computing activities. The amount of main  
system memory allocated to support graphics may vary depending on the  
graphics system, applications utilized, system memory size and other  
factors.  
If your computer is configured with more than 3 GB memory, the memory  
might be displayed as approximately 3 GB only (depending on the  
computer’s hardware specifications).  
This is correct because the operating system usually displays the available  
memory instead of the physical memory (RAM) built into the computer.  
Various system components (like the video adapter’s GPU and PCI  
devices like Wireless LAN, etc.) require their own memory space. Since a  
32-bit operating system cannot address more than 4 GB of memory, these  
system resources overlap the physical memory. It is a technical limitation  
that the overlapped memory is not available to the operating system. Even  
though some tools might display the actual physical memory built into your  
computer, the memory available to the operating system will still be  
approximately 3 GB only.  
Computers configured with a 64-bit operating system can address 4 GB or  
more of system memory.  
Battery Life  
Battery life may vary considerably depending on product model,  
configuration, applications, power management settings and features  
utilized, as well as the natural performance variations produced by the  
design of individual components. Published battery life numbers are

C850/C850D/L850/L850D  
achieved on select models and configurations tested by TOSHIBA at the  
time of publication. Recharge time varies depending on usage. Battery may  
not charge while computer is consuming full power.  
After going through many charge and discharge cycles, the battery will lose  
its ability to perform at maximum capacity and will need to be replaced.  
This is a normal phenomenon for all batteries. To purchase a new battery  
pack, see the accessories information that is shipped with your computer.  
Hard Disk Drive (HDD) Capacity  
1 Gigabyte (GB) means 109 = 1,000,000,000 bytes using powers of 10.  
The computer operating system, however, reports storage capacity using  
powers of 2 for the definition of 1 GB = 230 = 1,073,741,824 bytes, and  
therefore shows less storage capacity. Available storage capacity will also  
be less if the product includes one or more pre-installed operating systems,  
such as Microsoft Operating System and/or pre-installed software  
applications, or media content. Actual formatted capacity may vary.  
LCD  
Over a period of time, and depending on the usage of the computer, the  
brightness of the LCD screen will deteriorate. This is an intrinsic  
characteristic of LCD technology.  
Maximum brightness is only available when operating in AC power mode.  
Screen will dim when the computer is operated on battery power and you  
may not be able to increase the brightness of the screen.  
Graphics Processing Unit (GPU)  
Graphics processing unit (GPU) performance may vary depending on  
product model, design configuration, applications, power management  
settings and features utilized. GPU performance is only optimized when  
operating in AC power mode and may decrease considerably when  
operating in battery power mode.  
Total Available Graphics Memory is the total of, as applicable, Dedicated  
Video Memory, System Video Memory and Shared System Memory.  
Shared System Memory will vary depending on system memory size and  
other factors.  
Wireless LAN  
The transmission speed over the wireless LAN and the distance over which  
wireless LAN can reach may vary depending on surrounding  
electromagnetic environment, obstacles, access point design and  
configuration, and client design and software/hardware configurations.  
The actual transmission speed will be lower than the theoretical maximum  
speed.
