Compliance Statements
The X-C 6250 Pro (300) computer has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of the ;CC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
The X-C 6250 Pro (300) computer complies with Part 68 of the ;CC Rules. On
the bottom of this equipment is a label that contains, among other information,
the ;CC registration number and ringer equivalence number (REN) for this
equipment. If requested, this information must be provided to the telephone
company.
The REN is used to determine the quantity of devices which may be connected
to the telephone line. Excessive RENs on the telephone line may result in the
devices not ringing in response to an incoming call. In most, but not all areas,
the sum of the RENs should not exceed five (5.0). To be certain of the number
of devices that may be connected to the line, as determined by the total RENs,
contact the telephone company to determine the maximum REN for the calling
area.
The X-C 6250 Pro (300) computer may be connected to the telephone network
using the RJ-11 jack provided.
If this equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of service
may be required. If advance notice isn’t practical, the telephone company will
notify the customer as soon as possible. Also, you will be advised of your right
to file a complaint with the ;CC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the operation of the equipment. If

Keyboard Basics
The keyboard on the mobile computer looks much like the keyboard of a
typewriter and operates in almost the same way. While typewriter keys
put characters on paper, the keys on the laptop enter characters in the
computer and perform certain functions, depending on the application
or program. Typing skills are helpful but are not essential because
typing short commands or responses is easy.
The mobile computer features:
• A typewriter-style keyboard
• Twelve function keys, ;1-;12
• Embedded numeric keypad
• Mouse keys
• Special ;unction Keys (85-Key Keyboard Only)
CAUTION You can restart the mobile computer using the following
keys; however, restarting your computer while you are running
applications or working in Windows may corrupt files or data.
Restarting the Computer
Pressꢀ
To do this
START+SHUTDOWN+RESTART
Reboot the computer.
Reset the computer.
Press and hold both mouse
buttons for about 10 seconds
and then release the buttons.

Section 2. Using the Keyboard and Mouse
Term
Meaning
Double-click To click the left, primary mouse button twice in rapid
succession.
Pointing and double-clicking on an application icon
opens or launches the program associated with the icon.
Drag
To point, click, and press and hold down the left,
primary mouse button while you move the mouse. You
use drag to move icons from one window or directory to
another. To select text in a data entry field, you place the
cursor at the beginning of the text, click on the left,
primary mouse button, and drag the cursor over text.
You can then delete or type over the text.
General Guidelines
The mobile computer uses a Liquid Crystal Display (LCD), which is the
type of screen used on many notebook and sub-notebook computers.
One problem experienced on computers with an LCD display, especially
in cold environments, is that the cursor seems to “disappear” whenever
the mouse is moved quickly. To improve the visibility of the mouse
cursor, you should:
• Use a slow or medium speed/sensitivity level.
You can combine a higher level of acceleration with a slow or medium
speed/sensitivity level. This will allow you to move the mouse cursor
quickly by increasing your finger pressure, while still providing a finer
degree of control when you apply minimum pressure.
Changing the Speed of the Mouse
To change the speed of the mouse, from the Start Menu select Settings,
Control Panel, and then choose Mouse to make adjustments.

Section 4. If You Have a Radio Modem
What Can I Do with My Radio Modem?
The radio modem in your mobile computer gives you the freedom to
send and receive data without connecting to the wired telephone
system or traditional wired networks. Common uses of radio
communications include dispatching, personal messaging, and
accessing remote host computer systems.
Cellular radio modems offer an additional capability to use your
computer as a cellular phone. When you are not sending or receiving
data, you can switch the modem into voice mode using your mobile
computer’s Speaker Phone program. GSM modems offer voice, data,
fax, and short messaging system (SMS) and WLAN wireless network
cards offer wireless connections to your network
The exact capabilities of your radio modem are determined by the
communications software you are using, and the services provided by
your wireless network provider. Refer to the documentation provided
with your communications software for information on using the
program with a radio network. Your network provider can answer
questions regarding specific network features, host connectivity,
registration options, billing, and geographic coverage areas. In some
cases, your network provider can also assist you with selecting modem
setup options for your communications software.

Introduction
This section shows you how to access the System Configuration Utility
(SCU) in order to customize settings for your own personal preference.
It also covers viewing and changing IRQ settings.
CAUTION Changing settings may cause the mobile computer to
operate incorrectly. Change default settings only if you are
instructed to do so.
Using the System Configuration Utility
The System Configuration Utility (SCU) allows you to change default
settings for your hardware options and power management. The default
settings should not be changed unless you are installing new hardware
or adding memory. Otherwise, your existing hardware may not operate
properly.
You can change the power management options based on personal
preference. ;or example, the computer enters suspend mode after 2
minutes if it does not detect any keyboard or mouse activity. If you want
to change this time-out setting, use SCU to make this change. Other
power management options you may want to change include:
• When the system turns off the backlight (or MaxBright)
• When the hard disk is placed in standby mode
• How power is managed for the COM ports
• Whether the computer resumes when the radio modem detects a
ring signal
• Whether or not power management is enabled
Important Changing or disabling power management options can
decrease battery life. Set these options at levels that will use the
least amount of battery power.

Introduction
The mobile computer uses a Nickel Metal Hydride (NiMH) battery. This
section provides some important information about these types of
batteries and ways to extend their life.
Practical Battery Tips
Tip 1. Getting the most from your battery
• Your battery will last longer during the day if it is used and charged
between 10°C and 30°C (50°; and 86°;).
• Charge the battery nightly where the temperature will remain around
20°C (68°;).
• Set up your system to automatically suspend (turn off) while the
battery is charging.
This can be done by enabling the “Suspend on AC Power” option
under the Power, Suspend/Resume Control menu in the System
Configuration Utility (SCU). This allows the system to automatically
suspend while it is connected to external power.
Note Even the best maintained batteries eventually need to be
retired. They simply degrade from continuous use. Consider
replacing your battery if you are not getting the usage you need
from it.
Tip 2. Conserving power and extending battery life
• Turn off your computer by pressing ;N+O;; whenever you are not
using it.
• Make sure your system suspends automatically. PC Cards, custom
applications, or modified system settings can affect this.
Note An open file or directory in Windows Explorer will not allow
the computer to go into suspend mode.

Section 6. Managing Batteries and Power
• Unplug peripherals and remove peripheral and network PC Cards
when you are not using them.
• Certain devices and PC cards will prevent the unit from suspending
when they are inserted into a PC card slot on the unit. If they are
not required, and the unit will be used intermittently, the battery will
drain unnecessarily. They should be removed when not needed. To
do this, one must first shutdown the unit, remove the card, and then
reboot.
• External floppy and CD-ROM drives, as well as PC card storage
devices, will prevent the unit from going into suspend if the unit is
accessing them. ;or example, if a window is open to a file or
directory stored on a PC card, the unit will not suspend. Close the
file or directory when not required.
• If you have a monochrome display, turn off the backlight when you
do not need it.
• If you have a 10.4-inch color display, turn off MaxBright when you
do not need it.
• Use the SCU to set power management options at levels that will
consume the least amount of battery power (see Section 5,
“Customizing Settings,” for more information).
• Use the AC adapter or vehicle adapter whenever possible.
• Avoid exposing batteries to extremely hot or cold temperatures for
long periods.
• The mobile computer display does not require a screen saver. Using
screen savers consumes valuable battery power and is discouraged
unless the unit is connected to external power and an external
monitor.
• Store the battery within the recommended temperature range: 10°C
to 30°C (50°; to 86°;).
Tip 3. Determining when your battery has finished
charging
• Under normal circumstances, your battery is finished charging when
the external power indicator light stops blinking and remains solid.
79-0030-001 11 January 2001
Download from Www.Somanuals.com. All Manuals Search And Download.
63
X-C 6250 Pro (300) NT User’s Manual
To prevent possible damage to the battery, the system will not allow
a charge if the battery temperature is above 50°C (122°;) or below
5°C (41°;), such as in a closed, unattended vehicle. In this case,
your battery may not be fully charged.
• If you charge your battery every night, it is finished charging when
the Power Profiler application shows a full gas gauge even though
the external power indicator light may still be blinking.
If your battery is new, or if you have not used it for a week or more,
the gas gauge may be inaccurate because the battery naturally
discharges over time. In this case, wait until the external power
indicator light stops blinking and remains solid.
Tip 4. How your battery behaves in warm and cold
conditions
In warm conditions
• When using a battery in warm conditions, the battery capacity will
drain faster. In general, as the temperature rises, it is possible for the
battery to drain 20 percent faster at 40°C (104°;) and 50 percent
faster at 45°C (113°;).
• To prevent possible damage to the battery, the system will not allow
a charge if the battery temperature is above 45°C (113°;), such as
in a closed, unattended vehicle during the summer.
• If possible, charge the battery in a location with a moderate
temperature of around 20°C (68°;). The battery won’t last as long
during the day if charged at higher temperatures because heat slows
down the battery’s chemical reactions. Also, if the battery becomes
too hot while charging, the charge mode automatically switches from
;ast Charge to Slow Charge. Slow Charge takes much longer to finish
charging the battery.
• When charging the battery, leave the display tilted open and allow
unrestricted airflow so excess heat can escape from the battery
compartment and prevent the battery from overheating.

Section 6. Managing Batteries and Power
In cold conditions
• When using a battery in cold conditions, the battery capacity can
drain 30 percent faster at 4°C (39°;) and 70 percent faster at -11°C
(19°;).
• To prevent possible damage to the battery, the system will not allow
a charge if the battery temperature is below 5°C (41°;), such as in a
closed, unattended vehicle during the winter.
• If possible, charge the battery in a location with a moderate
temperature of around 20°C (68°;). The battery won’t last as long
during the day if charged at lower temperatures because cold slows
down the battery’s chemical reactions.
Tip 5. Preventing data loss
How to prevent data loss when removing the battery or storing
your computer
• You can lose data if you remove the battery while the computer is
operating on battery power. To prevent this, turn off the unit by
pressing ;N+O;; before you remove the battery.
• The computer is equipped with enough internal backup power to
maintain memory contents for about 5 minutes each time you
exchange batteries. Be careful not to exceed this 5 minute limit
when you replace the battery.
• If you plan to store your computer for more than 30 days, shut down
your computer to save data to the hard disk, and then press ;N+O;;
to turn off the computer. Remove the battery before storing the
computer.
Tip 6. Returning batteries for service
• When shipping batteries, use non-static packing material to reduce
the possibility of static discharge. Placing the battery in a non-static
bag is ideal; however, wrapping the battery in paper or newspaper is
also acceptable.
• Contact your supervisor or your organization’s help desk for correct
shipping procedures and information.

Section 6. Managing Batteries and Power
Low Battery Warnings
When the battery becomes low, the mobile computer beeps and the
battery indicator light blinks. If you are running Windows, a warning
message also appears on the screen periodically. Unless you connect
external power or replace the battery within a reasonable time, the
system turns off the computer automatically. If the battery voltage
becomes very low, the computer shuts off and you cannot turn it back
on until you correct the low battery condition.
Power-saving "eatures
Suspend
Suspend mode turns off the system if there is no activity for a period of
time. The computer also enters suspend mode if the battery capacity
becomes critically low and external power is not connected or the
battery is not replaced. Inactivity Suspend will not happen when certain
cards are inserted into a PC card slot on the unit. Shutdown the unit,
remove the card, then reboot.
Note Some systems do not automatically enter suspend mode
when they are connected to external power. Systems that can
suspend on external power have a user-defined option in the System
Configuration Utility (SCU) that enables or disables this feature. See
Section 5 for information about accessing the SCU.
By default, the computer enters suspend mode after two minutes of
inactivity. This “time-out” setting can be changed in the System
Configuration Utility (see Section 5, “Customizing Settings”). You can
place the computer in suspend mode manually by pressing ;N+O;;.
;iles and data are retained and you can resume where you left off by
pressing ;N+ON.

Leave the display tilted open and allow unrestricted airflow while the
battery is charging. This allows excess heat to escape from the battery
compartment and helps prevent the battery from overheating.
The battery starts fast charging automatically, and the external power
indicator light blinks while the battery is charging. At moderate
temperatures, around 70 degrees ;ahrenheit, the battery will complete
charging in 3 to 4 hours. Under extremely cold or hot temperatures,
however, the battery can take up to 16 hours to fully charge.
Battery Storage and Care
;ollow these guidelines to maintain performance of NiMH batteries.
• Avoid exposing batteries to extremely hot or cold temperatures for
long periods. To prevent possible damage to the battery, the mobile
computer does not allow the battery to charge if the internal
temperature of the battery gets too low (< 5°C or < 41°;) or too
high (> 50°C or > 122°;).
• Charge the batteries nightly where the temperature will remain
around 20°C (68°;).
• Store the batteries within the recommended temperature range:
10°C to 30°C (50°; to 86°;).
• After storage, or periods during which the battery has not been used,
deep cycling it up to four times in succession may increase its
capacity. You may want to do this over consecutive weekends since
each deep cycle process can take up to 40 hours. After this initial
conditioning, maintain battery capacity by deep cycling at the
recommended frequency.

Transferring "iles Using PC Cards
To transfer files using PC cards
This method of transferring files requires that the computer you are
exchanging files with is also equipped with a PC card socket.
1 Insert a PC memory or ATA card into the PC card socket of the
source computer.
2 Copy the file(s) you want to transfer from the hard disk to the PC
card.
The drive letter assigned to the card depends on the hardware
configuration of the computer.
3 Remove the card and insert it into the card socket of the destination
computer.
4 Copy the file(s) from the PC card to the hard disk of the destination
computer.
Using Bootable PC Cards
The mobile computer normally boots from the internal hard disk (drive
C); however, it might be necessary to boot from an alternate boot device
if the computer’s hard disk becomes corrupted or fails, or if you want to
boot another operating system.
You can boot from an approved external floppy disk drive (see Section 8
for more information), or you can use an SRAM PC Card or ATA ;lash
Card. Boot precedence is first from the SRAM PC card (drive C), then
the external floppy (drive A, removable), and then the internal hard
drive.
Important Do not use ;N+O;; to suspend the computer if you
have booted from a PC Card rather than the computer’s internal
hard disk. When you have finished using the card, remove it from
the computer and then press CTRL+ALT+DEL to restart the
system.

Section 8. Optional Equipment and Accessories
Surge Protection
A large number of computer and high technology equipment damage is
directly related to AC power and telephone line problems. These
problems can include surges, spikes, noise, interference, and weather-
related problems, which in turn can cause glitches, hang-ups, crashes,
performance slow downs, and down time with computer equipment.
The market is flooded with hundreds of AC power line surge
suppressors advertising high performance surge protection; only a few
of them actually provide adequate protection.
This section provides guidelines for selecting a quality surge suppressor
to be used with your mobile computer, and it helps identify a few
sources for products with acceptable performance.
Selecting the Right Surge Protection
Consider the level of quality you need when selecting a surge
suppressor. This depends on factors such as surge environment, the
type of equipment to be protected, and the quality of the electrical
wiring and service.
Surge Environment
Surge environment refers to the damage potential from electrical surges
in a particular geographical area. A high quality suppressor should be
used if there is frequent lightening activity in the area and the location
service is fed by overhead utility poles. An example of a high surge
environment would be *lorida; a low surge environment might be New
York.
Type of Equipment to be Protected
If the computer is equipped with a modem, the modem should also be
surge protected. Protecting the power line without protecting the
modem line provides only partial protection.

95
X-C 6250 Pro (300) NT User’s Manual
Quality of Electrical Wiring and Service
Wiring should be up to current NEC standards and have verified good
AC grounds. It is important that your computer system be plugged into
a grounded AC outlet when charging and that all peripherals connected
to your system reference the same AC ground.
Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors
such as Sutton Designs, APC, and Panamax. When you are looking for
a surge suppressor, consider these things.
• Expect to pay at least $50 for a good quality surge suppressor.
• The surge suppressor should be a UL 1449, 497, and 1283 listed
for surge suppression, modem surge protection, and R*I/EMI noise
filtering respectively.
• The surge suppressor should have diagnostic LEDs that verify good
AC ground, proper wiring, and proper surge operation. Lighted on/off
switches are not recommended since they can produce electrical
noise.
• The Joule ratings should be a minimum of 480 Joules for the AC
surge circuit.
• The Joule ratings should be a minimum of 240 Joules for the
modem.
• The modem surge circuit should present low capacitance to the
modem line or it will slow the transmission rate. Capacitance should
be specified at less than 50 picofarads.
• Quality surge suppressor manufacturers generally offer a lifetime
warranty.
• Consider obtaining a protected equipment coverage policy which
insures the equipment in the event of surge damage.
• The devices that will be attached to the computer also need to be
surge protected.

Introduction
The mobile computer is ruggedized and weather resistant. Handle it
with the normal care required by any sophisticated electronic
equipment, and the computer will provide reliable service even under
harsh field conditions.
;ollow the guidelines below to care for your unit.
If You Have a Touch Screen
CAUTION
• Always use an approved stylus.
• Never use sharp, hard, or abrasive implements on the touch
screen such as ball point pens, pencils, or keys. They could
damage the screen.
• To clean the touch screen panel, apply a household glass cleaner
to a soft, clean, dry cloth and wipe the screen.
Hard Drive Care and Handling
There are two hard drive options for the mobile computer: a shock-
mounted 2.5-inch hard drive and a PC Card Type III hard drive. All hard
drives contain media for data storage in the form of a rotating disk,
read/write head(s), a motor, and electronics for interfacing and control.
Each hard drive type can be susceptible to damage from severe shock
and other stressful environmental impacts. The degree of susceptibility
to damage is directly related to the individual hard drive and mounting
system employed.
When reading or writing to the hard disk, the head is “flying” on a thin
layer of air, micro-inches above the disk. A shock can cause the read/
write head to contact the spinning disk, resulting in immediate loss of
stored data and possible physical damage to the disk. It could also

Section 10. Maintenance and Storage
create loose debris in the drive enclosure that may cause progressive
damage over time.
To reduce exposure to high operating shocks, the mobile computer uses
power modes for the hard drive that prevent the read/write heads from
being positioned over the disk when it is not being used: idle mode and
standby mode.
You can reduce the risk of damage to the hard drive and increase the
reliability of the hard drive and data integrity by following the
recommendations below.
Internal Hard Drives
• Do not intentionally drop the computer. The unit is designed to
withstand the day to day rigors of the mobile environment and
provide years of reliable service. The useful life of the product can be
enhanced by not intentionally abusing it.
• Use the power management feature control in the System
Configuration Utility (SCU). Power management conserves power but
also ensures that the read/write heads are unloaded and the hard
drive is spun down within the time specified.
• Whenever possible suspend the unit by pressing ;N+O;; before
moving it from one location to another. This will unload the read/
write heads and spin down the disk.
• Maintain the environmental seal of the computer by keeping the PC
Card door closed and latched. Also avoid exposing the unit to
extreme temperatures or moisture when the PC Card door is open.
• Periodically backup or archive important files and data.

External PC Card Hard Drives
Each PC Card hard drive manufacturer provides specific guidelines for
the care and handling of the product. In addition, follow these
recommendations:
• When the PC Card hard drive is not inserted in a PC Card socket,
store the hard drive in a protective carrying case. This will help
protect it from inadvertent shocks.
• Always use care when handling the hard drive. Do not drop, bend,
flex, or crush it.
• Avoid exposing the PC Card hard drive to extreme moisture, heat, or
sunlight.
• Keep all debris out of the connector to ensure good electrical
connections.
• There are no user repairable parts in the PC Card hard drive. Do not
attempt to disassemble any part of the hard drive. The warranty will
be voided if drive seals are broken or screws have been removed.
• Periodically backup or archive important files and data.

Section 10. Maintenance and Storage
Battery Maintenance and Storage
Maintaining Batteries
;ollow these guidelines to maintain performance of Nickel Metal
Hydride (NiMH) batteries.
• Avoid exposing batteries to extremely hot or cold temperatures for
long periods. To prevent possible damage to the battery, the mobile
computer does not allow the battery to charge if the internal
temperature of the battery gets too low (< 5°C or < 41°;) or too
high (> 50°C or > 122°;).
• Charge the battery nightly where the temperature will remain around
20°C (68°;).
Storing Batteries
• Store the battery within the recommended temperature range: 10°C
to 30°C (50°; to 86°;).
• Unused or stored batteries can lose power over time. When you
install a battery that has not been used for awhile, connect external
power to the computer and charge the battery.
• After storage, deep cycling the battery up to four times in succession
may increase its capacity. You may want to do this over consecutive
weekends since each deep cycle process can take up to 40 hours.
After this initial conditioning, maintain battery capacity by deep
cycling at the recommended frequency.

Maintaining Your Computer
;ollow these guidelines to help maintain the condition and performance
of your computer.
• Turn off the computer when you are not using it.
• Charge the batteries daily or whenever their capacity is low.
• Operate the computer within the recommended temperature ranges
of -20°C to +60°C (-4°; to +140°;).
Care and Cleaning
Physical Inspection Periodically inspect the computer and accessories
for wear, damage, or loose or missing parts. Identifying and correcting
potential problems early can help reduce the need to return the unit for
service.
Outside Case Like all tools, the outside of the computer will get dirty
with use. The case is made of painted Magnesium with Santoprene
bumpers and polycarbonate blend (plastic) doors and covers. These
®
areas can be cleaned with a solution of one part ;ormula 409 and one
part water. ;ollow the procedure below.

Batteries
The battery does not charge
• To prevent possible damage to the battery, the system will not allow
a charge if the battery temperature is extremely hot or cold (such as
in a closed, unattended vehicle). If possible, charge the battery in a
location with a moderate temperature of around 20°C (68°;).
• Keep the display tilted open and allow unrestricted airflow while the
battery is charging so excess heat can escape and prevent the
battery from overheating.
• If possible, turn off the computer while the battery is charging.
• Try enabling the “Suspend on AC Power” option under the Power,
Suspend/Resume Control menu in the System Configuration Utility
(SCU). This allows the system to automatically suspend while it is
connected to external power.
• If the battery is new or has been stored for a week or more, follow
this procedure:
1 Make sure the computer is turned off (press ;N+O;;).
2 Open the battery door and remove the battery.
3 Connect the AC adapter to the computer and an AC wall outlet,
and then turn on the computer by pressing ;N+ON
(;N+SPACEBAR).
4 Reinstall the battery and replace the battery door.
5 Allow the system to remain idle for one hour with the AC adapter
connected to the computer.
The external power light blinks when the battery starts charging.
6 If the battery still fails to charge after an hour, remove the battery,
wait several seconds, and then install it again.
If the battery does not begin charging within several minutes,
return the unit for service.

ꢀBatteries
The batteries take much longer than three hours to charge
• Under moderate temperatures, about 21°C (70º;), the computer’s
battery takes 3 to 4 hours to completely charge. Under extremely
cold or hot temperatures, however, the battery can take up to 16
hours to fully charge.
The batteries don’t last very long
• Over time, your battery may develop “memory effect.” This occurs
when the battery is partially discharged and recharged repetitively
without full discharge. A partial or shallow discharge means that
you use less than 50 percent of its capacity before charging.
• As your battery ages, the maximum capacity that it can hold
naturally decreases, and even the best maintained batteries
eventually need to be retired. Consider replacing the battery if you
are not getting the usage you need from it.
The charging light doesn’t flash
• Verify that a battery is installed in the unit.
• Check AC power connection.
• Check the Power Profiler to see if the gas guage is full.
The ambient temperature rises rapidly when charging the battery
at room temperature
• This is normal. The internal ambient temperature is always 0º to 16º
higher than the external ambient temperature. Ambient temperature
is not used for charge termination criteria.

ꢀBatteries
The gas gauge reads “full,” but the indicator light is still blinking
• If you charge your battery daily, rely on the gas gauge reading to
determine battery capacity. The charge mode may have switched
from ;ast to Slow because the battery became too hot. The charging
process is trying to put a little more capacity into the battery;
however, external power can be removed because the battery is
virtually full.
• If your battery is new or has not been used for several weeks, rely on
the indicator light to determine when the battery is fully charged.
The gas gauge is unreliable in these cases; it may read 100 percent,
when the actual capacity is only 10 percent.
Display
The display performance is slow
• The temperature may be too cold. Move the computer to a warmer
operating environment.
I can’t read the display
• Adjust the backlight.
-On a monochrome display, pressing ;N+;1 toggles the backlight on
and off.
-On a color display, the backlight is on whenever the computer is
running. Pressing ;N+;1 toggles the MaxBright feature on and off.
• The automatic power-saving mode may have shut off (suspended)
the computer. Press ;N+ON to resume.
• Adjust the contrast by pressing ;N+;4 and ;N+;5 (these keys are
not active on a 10.4-inch color display).
