General safety  
Follow these rules to ensure general safety:  
• Observe good housekeeping in the area of the machines during and after maintenance.  
• When lifting any heavy object:  
1. Make sure that you can stand safely without slipping.  
2. Distribute the weight of the object equally between your feet.  
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.  
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the  
muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you  
think is too heavy for you.  
• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.  
• Before you start the machine, make sure that other service technicians and the customer's personnel are  
not in a hazardous position.  
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing  
the machine.  
• Keep your toolcase away from walk areas so that other people will not trip over it.  
• Do not wear loose clothing that can be trapped in the moving parts of a machine. Make sure that your  
sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.  
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, about 8  
centimeters (3 inches) from the end.  
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing, because metal  
objects are good electrical conductors.  
• Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using  
solvents, or working in any other conditions that might be hazardous to your eyes.  
• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device  
that is worn or defective.  
• Reinstall all covers correctly before returning the machine to the customer.  
• Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan  
louvers or cover them with labels or stickers.

Electrical safety  
Observe the following rules when working on electrical equipment.  
Important:  
Use only approved tools and test equipment. Some hand tools have handles covered with a soft material  
that does not insulate you when working with live electrical currents.  
Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to  
decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.  
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical  
accident occurs, you can then operate the switch or unplug the power cord quickly.  
• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.  
• Disconnect all power before:  
– Performing a mechanical inspection  
– Working near power supplies  
– Removing or installing main units  
• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer  
to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position.  
• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:  
– Ensure that another person, familiar with the power-off controls, is near you.  
Attention: Another person must be there to switch off the power, if necessary.  
– Use only one hand when working with powered-on electrical equipment; keep the other hand in your  
pocket or behind your back.  
Attention: An electrical shock can occur only when there is a complete circuit. By observing the above  
rule, you may prevent a current from passing through your body.  
– When using testers, set the controls correctly and use the approved probe leads and accessories for  
that tester.  
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as  
metal floor strips and machine frames.  
Observe the special safety precautions when you work with very high voltages; Instructions for these  
precautions are in the safety sections of maintenance information. Use extreme care when measuring  
high voltages.  
• Regularly inspect and maintain your electrical hand tools for safe operational condition.  
• Do not use worn or broken tools and testers.  
• Never assume that power has been disconnected from a circuit. First, check that it has been powered off.  
• Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors,  
nongrounded power extension cables, power surges, and missing safety grounds.  
• Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is  
conductive; such touching can cause personal injury and machine damage.  
• Do not service the following parts with the power on when they are removed from their normal operating  
places in a machine:  
– Power supply units  
– Pumps  
– Blowers and fans  
– Motor generators  
– Similar units to listed above  
This practice ensures correct grounding of the units.  
• If an electrical accident occurs:

– Use caution; do not become a victim yourself.  
– Switch off power.  
– Send another person to get medical aid.  
Safety inspection guide  
The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each  
machine was designed and built, required safety items were installed to protect users and service technicians  
from injury. This guide addresses only those items. You should use good judgment to identify potential  
safety hazards due to attachment of non-Lenovo features or options not covered by this inspection guide.  
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and  
whether you can continue without first correcting the problem.  
Consider these conditions and the safety hazards they present:  
• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal  
electrical shock)  
• Explosive hazards, such as a damaged CRT face or a bulging capacitor  
• Mechanical hazards, such as loose or missing hardware  
To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning  
of every service task. Begin the checks with the power off, and the power cord disconnected.  
Checklist:  
1. Check exterior covers for damage (loose, broken, or sharp edges).  
2. Power off the computer. Disconnect the power cord.  
3. Check the power cord for:  
a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground  
continuity for 0.1 ohm or less between the external ground pin and the frame ground.  
b. The power cord should be the type specified in the parts list.  
c. Insulation must not be frayed or worn.  
4. Check for cracked or bulging batteries.  
5. Remove the cover.  
6. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo  
alterations.  
7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or  
other liquids, or signs of fire or smoke damage.  
8. Check for worn, frayed, or pinched cables.  
9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.  
Handling devices that are sensitive to electrostatic discharge  
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to  
electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects.  
Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the  
person handling the part are all at the same charge.  
Notes:  
1. Use product-specific ESD procedures when they exceed the requirements noted here.  
Chapter 1. Safety information  
Download from Www.Somanuals.com. All Manuals Search And Download.

2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.  
When handling ESD-sensitive parts:  
• Keep the parts in protective packages until they are inserted into the product.  
• Avoid contact with other people.  
• Wear a grounded wrist strap against your skin to eliminate static on your body.  
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when  
you are wearing a wrist strap.  
• Use a grounded work mat to provide a static-free work surface. The mat is especially useful when  
handling ESD-sensitive devices.  
• Select a grounding system, such as those listed below, to provide protection that meets the specific  
service requirement.  
Note: The use of a grounding system to guard against ESD damage is desirable but not necessary.  
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.  
– When working on a double-insulated or battery-operated system, use an ESD common ground or  
reference point. You can use coax or connector-outside shells on these systems.  
– Use the round ground prong of the ac plug on ac-operated computers.  
Grounding requirements  
Electrical grounding of the computer is required for operator safety and correct system function. Proper  
grounding of the electrical outlet can be verified by a certified electrician.

Chapter 2. Important service information  
This chapter presents the following important service information that applies to all machine types supported  
by this manual:  
•
“Strategy for replacing FRUs” on page 27  
–
“Strategy for replacing a hard disk drive” on page 28  
–
“Important notice for replacing a system board” on page 28  
•
“Important information about replacing RoHS compliant FRUs” on page 28  
Important: BIOS and device driver fixes are customer-installable. The BIOS and device drivers are available  
at http://www.lenovo.com/support.  
Strategy for replacing FRUs  
Before replacing parts:  
Make sure that all software fixes, drivers, and BIOS downloads are installed before replacing any FRUs  
listed in this manual.  
After a system board is replaced, ensure that the latest BIOS is installed to the system board before  
completing the service action.  
To download software fixes, drivers, and BIOS, do the following:  
1. Go to http://www.lenovo.com/support.  
2. Click Download Drivers & Software. The Web site offers three options to begin your search:  
• Search by product number  
• Search through the product auto-detect function  
• Search by product category  
3. Follow the directions on the screen and install the necessary software.  
Notes: If you need to improve the computer performance, you also could download and install the latest  
BIOS utility from the Support Web site.  
• Do not try to update the BIOS settings for any computer unless you have been trained and certified. An  
untrained person runs the risk of damaging the computer.  
• Before installing the latest utility, make sure that the battery is fully charged and an ac power adapter is  
connected.  
• Do not turn off or put your computer into sleep or hibernation until the update has been completed.  
Otherwise, the system board might be damaged.  
Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs:  
• If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall  
the original FRU before you continue.  
• Some computers have both a processor board and a system board. If you are instructed to replace either  
the processor board or the system board, and replacing one of them does not correct the problem,  
reinstall that board, and then replace the other one.

• If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error.  
Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change.  
Replace only the FRU that changed the symptoms.  
Strategy for replacing a hard disk drive  
Always try to run a low-level format before replacing a hard disk drive (HDD). This will cause all customer data  
on the hard disk to be lost. Be sure that the customer has a current backup of the data before doing this task.  
Attention: The drive startup sequence in the computer you are servicing may have been changed. Be  
extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect  
drive, data or programs can be overwritten.  
Important notice for replacing a system board  
Some components mounted on a system board are very sensitive. Improper handling of a system board can  
cause damage to those components, and may cause a system malfunction.  
Attention: When handling a system board:  
• Do not drop a system board or apply any excessive force to it.  
• Avoid rough handling of any kind.  
• Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.  
Important information about replacing RoHS compliant FRUs  
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive  
(2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS  
requirements must be implemented on Lenovo products placed on the market after June 2006. Products  
on the market before June 2006 are not required to have RoHS compliant parts. If the original FRU parts  
are non-compliant, the replacement parts also can be non-compliant. That is, if the original FRU parts are  
RoHS compliant, the replacement part also must be RoHS compliant.  
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified by the unique  
FRU part numbers.  
Lenovo plans to transit to RoHS compliance before the implementation date and expects its suppliers to be  
ready to meet Lenovo’s requirements and schedule in the European Union. Products sold between 2005  
and 2006 might contain some RoHS compliant FRUs. The following statement pertains to the products  
with RoHS compliant FRUs.  
RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date, the  
failed RoHS compliant parts must be replaced with compliant parts and only the following FRUs can be  
used: identified as compliant in the Hardware Maintenance Manual or direct substitutions can be used.  
• Compliant FRUs identified in Hardware Maintenance Manual  
• Direct substitutions with different FRU part numbers automatically shipped by the distribution center at  
the time of order  
For products shipped after June 2006

This chapter presents following information:  
•
•
“What to do first” on page 29  
“Power system checkout” on page 30  
Before you go to the checkout guide, be sure to read the following important notes.  
Important notes:  
• Only certified trained personnel should service the computer.  
• Before replacing any FRU, read the entire page on removing and replacing FRUs.  
• When you replace FRUs, it is recommended to use new nylon-coated screws.  
• Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer  
that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs  
might be overwritten.  
• Replace a FRU only with another FRU of the correct model. When you replace a FRU, make sure that the model  
of the machine and the FRU part number are correct by referring to the FRU parts list.  
• A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a  
variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge,  
or software errors. Consider replacing a FRU only when a problem recurs. If you suspect that a FRU is defective,  
clear the error log and run the test again. If the error does not recur, do not replace the FRU.  
• Be careful not to replace a nondefective FRU.  
What to do first  
When you do return a FRU, you must include the following information in the parts exchange form or  
parts return form that you attach to it:  
1. Name and phone number of service technician  
2. Date of service  
3. Date on which the machine failed  
4. Date of purchase  
5. Procedure index and page number in which the failing FRU was detected  
6. Failing FRU name and part number  
7. Machine type, model number, and serial number  
8. Customer's name and address  
Note: During the warranty period, the customer may be responsible for repair costs if the computer damage  
was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper  
maintenance by the customer. Following is a list of some common items that are not covered under warranty  
and some symptoms that might indicate that the system was subject to stress beyond normal use.  
Before checking problems with the computer, determine whether the damage is covered under the warranty  
by referring to the following list:  
The following are not covered under warranty:  
• LCD panel cracked from the application of excessive force or from being dropped

Power system checkout  
To verify a symptom, do the following:  
1. Turn off the computer.  
2. Remove the battery pack.  
3. Connect the ac power adapter.  
4. Check that power is supplied when you turn on the computer.  
5. Turn off the computer.  
6. Disconnect the ac power adapter and install the charged battery pack.  
7. Check that the battery pack supplies power when you turn on the computer.  
If you suspect a power problem, see the appropriate one of the following power supply checkouts:  
•
•
•
“Checking the ac power adapter” on page 30  
“Checking operational charging” on page 31  
“Checking the battery pack” on page 31  
Checking the ac power adapter  
You are here because the computer fails only when the ac power adapter is used.  
• If the power-on indicator does not turn on, check the power cord of the ac power adapter for correct  
continuity and installation.  
• If the computer does not charge during operation, go to “Checking operational charging” on page 31  
To check the ac power adapter, do the following:  
1. Unplug the ac power adapter cable from the computer.  
2. Measure the output voltage at the plug of the ac power adapter cable. See the following figure:  
Pin  
1
Voltage (V dc)  
+20  
0
2
Note: Output voltage of pin no.2 of the ac power adapter may different from the one you are servicing.  
3. If the voltage is not correct, replace the ac power adapter.  
4. If the voltage is acceptable, do the following:  
• Replace the system board.  
• If the problem persists, go to Chapter 5 “Lenovo B575e” on page 37.  
30 Hardware Maintenance Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Note: Noise from the ac power adapter does not always indicate a defect.  
Checking operational charging  
To check whether the battery charges properly during operation, use a discharged battery pack or a battery  
pack that has less than 50% of the total power remaining when installed in the computer.  
Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery  
pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does  
not turn on, replace the battery pack.  
If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is  
still not charged, go to the next section.  
Checking the battery pack  
Battery charging does not start until the power meter shows that less than 95% of the total power remains;  
under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from  
being overcharged or from having a shortened life.  
To check your battery, move your cursor to the power meter icon in the icon tray of the Windows® taskbar  
and wait for a moment (but do not click it), and the percentage of battery power remaining is displayed. To  
get detailed information about the battery, double-click the power meter icon.  
Note: If the battery pack becomes hot, it may not be able to be charged. Remove it from the computer and  
leave it at room temperature for a while. After it cools down, reinstall and recharge it.  
To check the battery pack, do the following:  
1. Power off the computer.  
2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the  
following figure:  
Terminal  
Voltage (V dc)  
+ 0 to + 14  
Ground (-)  
1
7
3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.  
Note: Recharging will take at least 3 hours, even if the indicator does not turn on.  
If the voltage is still less than +11.0 V dc after recharging, replace the battery.  
4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 5 and 7.  
The resistance must be 4 to 30 K Ω.  
If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system  
board.

“Power management” on page 34  
Recovering the computer settings  
Performing backup and recovery operations using the OneKey Recovery Pro program  
The OneKey Recovery Pro program enables you to back up all your hard disk drive contents including the  
operating system, data files, software programs, and personal settings. You can designate where the  
OneKey Recovery Pro program stores the backup. After you have backed up the contents on the hard disk  
drive, you can restore the complete contents of the hard disk drive, restore only the selected files, or restore  
only the Windows operating system and applications.  
Restoring factory contents using the Product Recovery program  
On the Windows 7 operating system, you can use recovery media to restore the computer settings to the  
factory contents only.  
Attention: When you use the Product Recovery program to restore the computer settings, all the data you  
have stored on the hard disk drive will be deleted and the computer settings will be restored to the factory  
contents. During the restoring process, you will be given the option to save one or more files currently on the  
hard disk drive to other media before the data is deleted.  
Passwords  
As many as two passwords might be needed for a Lenovo notebook computer: the power-on password, the  
hard disk password, and the supervisor password.  
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the  
computer is turned on. The computer does not start until the password is entered.  
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating  
system is started.  
Power-on password  
A power-on password (POP) protects the system from being powered on by an unauthorized person. The  
password must be entered before an operating system can be booted.  
Supervisor password  
A supervisor password (SVP) protects the system information stored in the BIOS. The user must enter the  
SVP in order to get access to the BIOS and change the system configuration.  
Attention: If the SVP has been forgotten and cannot be made available to the service technician, there is no  
service procedure to reset the password. The system board must be replaced for a scheduled fee.
