iv Hardware Maintenance Manual
Chapter 1. Safety information
This chapter presents the following safety information that you need to be
familiar with before you service a Lenovo notebook computer.
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 tool case 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 non-conductive 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 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, non-grounded 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 as 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 cathode ray tube
(CRT) face or a bulging capacitor · Mechanical hazards, such as loose or
missing hardware
2 Hardware Maintenance Manual
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
authorized type specified for your computer. Go to: http:// www.lenovo.com
/serviceparts-lookup 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. 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.
Chapter 1. Safety information 3
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. General checkout
This chapter contains the following topics:
Before you go to the checkout instructions, ensure that you 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. · 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 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. Failure symptoms, error codes
appearing on the display, and beep symptoms 6. Procedure index and page number
in which the failing FRU was detected 7. Failing FRU name and part number 8.
Machine type, model number, and serial number 9. 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,
