iv Hardware Maintenance Manual
Chapter 1. Safety information
This chapter presents following safety information that you need to be familiar with before you service a
Lenovo Notebook.
• “General safety” on page 1
• “Electrical safety” on page 2
• “Safety inspection guide” on page 3
• “Handling devices that are sensitive to electrostatic discharge” on page 3
• “Grounding requirements” on page 4
• “Safety notices (multilingual translations)” on page 4
• “Laser compliance statement (multilingual translations)” on page 19

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:

2 Hardware Maintenance Manual

 – 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 3

 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.
4. Restart the computer.

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.

© Copyright Lenovo 2012, 2013 27

• 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

Chapter 3. General checkout
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 subjected 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:

30 Hardware Maintenance Manual

 • If the problem persists, go to Chapter 5 “Lenovo E49 and ZhaoYang E49” on page 37.

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

The battery status icon in the Windows® notification area displays the percentage of battery power remaining.

Passwords
As many as two passwords might be needed for a Lenovo notebook computer: the power-on password
and the supervisor password.

© Copyright Lenovo 2012, 2013 33

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.

Power management
Note: Power management modes are not supported for APM operating system.

To reduce power consumption, the computer has three power management modes: screen blank, sleep,
and hibernation.

Screen blank mode

In the following circumstances, the computer goes into screen blank mode:
• The time set on the “Turn off monitor” timer on the Windows 7 operating system expires.
To end screen blank mode and resume normal operation, press any key.
• You have pressed Fn+F2.
To end screen blank mode and resume normal operation, press Fn+F2.

Sleep mode
When the computer enters sleep mode, the following events occur in addition to what occurs in screen
blank mode:
• The LCD is powered off.
• The hard disk drive is powered off.
• The CPU stops.

To enter sleep mode, press Fn+F1.

In certain circumstances, the computer goes into sleep mode automatically:

• If a “suspend time” has been set on the timer, and the user does not do any operation with the keyboard,
the hard disk drive, the parallel connector, or the diskette drive within that time.
• If the battery indicator blinks orange, indicating that the battery power is low.

To cause the computer to return from sleep mode and resume the operation, do one of the following:
• Press the Fn key.
• Open the LCD cover.
• Turn on the power button.

34 Hardware Maintenance Manual

Also, when the time set on the resume timer elapses, the computer automatically returns from sleep mode
and resumes operation.

Note: The computer does not accept any input immediately after it enters sleep mode. Wait a few seconds
before taking any action to reenter operation mode.

Hibernation mode
In hibernation mode, the following occurs:
• The system status, RAM, VRAM, and setup data are stored on the hard disk drive.
• The system is powered off.

If you have defined one of the following actions as the event that causes the system to go into hibernation
mode, perform that action.
• Closing the lid.
• Pressing the power button.

Also, the computer goes into hibernation mode automatically in either of the following conditions:
• If a “hibernation time” has been set on the timer, and if the user does not do any operation with the
keyboard, the hard disk drive, the parallel connector, or the diskette drive within that time.
• If the timer conditions are satisfied in suspend mode.

When the power is turned on, the computer returns from hibernation mode and resumes operation. The
hibernation file in the boot record on the hard disk drive is read, and system status is restored from the
hard disk drive.

Chapter 9. Parts list
This chapter contains following lists of the service parts.
• “Overall” on page 78
• “LCD FRUs” on page 82
• “Keyboard” on page 84
• “Miscellaneous parts” on page 85
• “ac power adapters” on page 86
• “Power cords” on page 86

Notes:
• Each FRU is available for all types or models, unless otherwise specified.
• A CRU (customer replaceable unit) is identified by a single asterisk (*) or two asterisks (**) in the CRU ID column. An
N in the CRU ID column means that the part is not a CRU. A single asterisk (*) means that the part is a Self-service
CRU; two asterisks (**) means that the part is an Optional-service CRU.
CRU statement for customers:
You can resolve some problems with your product with a replacement part you can install yourself, called a
“Customer Replaceable Unit” or “CRU.” Some CRUs are designated as self-service CRUs and others are
designated as optional-service CRUs. Installation of self-service CRUs is your responsibility. For optional-service
CRUs, you can either install the CRU yourself or you can request that a Service Provider install the CRU according
to the warranty service for your product. If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU
information and replacement instructions are shipped with your product and are available from Lenovo at any time
upon request. You can find a list of CRUs for your product in this Hardware Maintenance Manual. An electronic
version of this manual can be found at http://www.lenovo.com/UserManuals. Follow the on-screen instructions to
find the manual for your product. You might be required to return the defective CRU. When return is required: (1)
return instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you
might be charged for the replacement CRU if Lenovo does not receive the defective CRU within thirty (30) days of
your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details.
Lenovo computers contain the following types of CRUs:
– Self-service CRUs: These CRUs unplug or are held by no more than two screws. Examples of these types
of CRUs include the ac power adapter, power cord, battery, and hard disk drive. Other self-service CRUs
depending on product design might include the memory module, wireless card, keyboard, and palm rest
with finger print reader and touch pad.
– Optional-service CRUs: These CRUs are isolated parts within the computer that are concealed by an access
panel that is typically secured by more than two screws. Once the access panel is removed, the specific
CRU is visible.
