Follow these rules below to ensure general safety:
• Observe a good housekeeping in the area where the machines are put during
and after the 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 it.
4. Lift it by standing or pushing up with your leg muscles; this action could
avoid 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 machine unsafe.
• Before you start the machine, make sure that other service representatives
and the customer are not in a hazardous position.
• Please remove 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 it
over.
• Do not wear loose clothing that can be trapped in the moving parts of the
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 the
nonconductive clip, about 8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for
your clothing.
Attention: 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 may 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 the overheating of internal
components. Do not obstruct fan louvers or cover them with labels or
stickers.
General safety
Safety information
3
Observe the following rules when working on electrical equipments.
• 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 the 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. Be extremely careful when you measure the 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 it
to make sure that it has been powered off.
Electrical safety
Important:
Use only approved tools and test equipments. Some hand tools have
handles covered with a soft material that does not insulate you when
working with live electrical currents.
Many customers have rubber floor mats near their machines that contain
small conductive fibers to decrease electrostatic discharges. Do not use such
kind of mat to protect yourself from electrical shock.
Safety information

The purpose of this inspection guide is to assist you in identifying potential
unsafe conditions. As each machine was designed and built, required safety
items were installed to protect users and service personnel 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 potential 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. Turn 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.

General checkout
Important notes:
•Only certified trained personnel can service the computer.
•Before replacing any FRU, read the entire page on removing and
replacing FRUs.
•When you replace FRUs, 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 an FRU only with another FRU of the correct model. When
you replace an FRU, make sure that the machine model and the FRU part
number are correct by referring to the FRU parts list.
•An FRU should not be replaced just 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 an FRU
only when a problem recurs. If you suspect that an FRU is defective,
clear the error logs and run the test again. If the error does not recur, do
not replace the FRU.
•Be careful not to replace a nondefective FRU.

Perform operational charging. If the battery status indicator or icon does not
light on, remove the battery pack and let it return to room temperature. Reinstall
the battery pack. If the charge indicator or icon is still off, replace the battery
pack.
If the charge indicator still does not light 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.

• “Restoring the factory contents by using Recovery Disc Set” on page 23
• “Passwords” on page 24
• “Power management” on page 25
When the hard disk drive or solid state drive is replaced because of a failure, no
product recovery program is on the new drive. In this case, you must use the
Recovery Disc Set for the computer. Order the Recovery Disc Set and the drive at
the same time so that you can recover the new drive with the pre-installed
software when they arrive.
The Recovery Disc Set consists of the following set of DVDs to restore the
computer to the original factory configuration.
Start Recovery Disc (one disc)
This disc is used to format the hard disk drive and initiate the recovery process.
Operating System Recovery Disc (one or more discs)
This disc restores the Microsoft Windows operating system.
Applications and Drivers Recovery Disc (one or more discs)
This disc restores the pre-installed applications and drivers on the computer.
Supplemental Recovery Disc
This disc contains additional content, such as software for specific models and
updates to the software that was preloaded on the computer. Not all recovery
disc sets come with a Supplemental Recovery Disc.
To restore the computer to the original factory configuration using the recovery
disc set, do the following:
1. Insert the bootable Start Recovery Disc into the optical drive.
2. Start the computer. When the Lenovo logo comes up, immediately press F12;
on the boot sequence menu, select the optical drive as the first boot-up device.
The computer will boot from the Start Recovery Disc. Follow the on-screen
instructions to begin the recovery process.
3. Read the license. If you agree with the terms, select I accept these terms and
conditions and then click Next.
4. Insert the Operating System Recovery Disc when prompted and click Yes to
begin the operating system recovery process.
5. Insert the Applications and Drivers Recovery Disc when prompted and then
click OK to begin the applications and drivers recovery process.
6. If you have a Supplemental Recovery Disc, insert it when prompted and click
Yes. If you do not have a Supplemental Recovery Disc, click No.

7. When all of the data has been copied from the last disc in the set, remove the
disc and restart the computer.
8. When the recovery process is complete, the Welcome to the Microsoft
Windows screen is displayed. Follow the instructions on the screen to
complete the Windows setup.
As many as three passwords may be needed for any Lenovo computer: the
power-on password (POP), the hard disk password (HDP), and the supervisor
password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear
when the operating system is booted.
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.
Hard-disk password
There are two hard-disk passwords (HDPs):
+ User HDP - for the user
+ Master HDP - for the system administrator, who can use it to get access to the
hard disk drive even if the user has changed the user HDP
Attention: If the user HDP has been forgotten, check whether a master HDP has
been set. If it has, it can be used for access to the hard disk drive. If no master
HDP is available, neither Lenovo nor Lenov authorized service technicians
provide any services to reset either the user or the master HDP, or to recover data
from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS
Setup Utility. The user must enter the SVP in order to get access to the BIOS
Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the
servicer, there is no service procedure to reset the password. The system board
must be replaced for a scheduled fee.
Note: The remainder of the recovery process is fully automated and no
action is required by you. The computer will restart into the Windows
desktop several times and you might experience periods when no activity is
apparent on the screen for several minutes at a time. This is normal.

This section presents notices related to removing and replacing parts. Read this
section carefully before replacing any FRU.
Screw notices
Loose screws can cause a reliability problem. In the Lenovo computer, this
problem is addressed with special nylon-coated screws that have the following
characteristics:
• They maintain tight connections.
• They do not easily come loose, even with shock or vibration.
• They are harder to tighten.
• Each one should be used only once.
Do the following when you service this machine:
• Keep the screw kit in your tool bag.
• Remove screws carefully for reuse.
• Use a torque screwdriver if you have one.
Tighten screws as follows:
•Plastic to plastic
Turn an additional 90° after the screw head touches the surface of the plastic
part:
•Logic card to plastic
Turn an additional 180° after the screw head touches the surface of the logic
card:
•Torque driver
If you have a torque screwdriver , refer to the “Torque” column for each step.
• Make sure that you use the correct screws. If you have a torque screwdriver,
tighten all screws firmly to the torque shown in the table. Never use a screw
that you removed. Use a new one. Make sure that all screws are
tightened firmly.
• Ensure torque screwdrivers are calibrated correctly following country
specifications.
