Lenovo 100e Hardware Maintenance Manual

General safety 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 over it.

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.

About this manual

Electrical safety Observe the following rules when working on electrical equipments.

Important: Useonlyapproved toolsand testequipments.Somehand toolshavehandles coveredwithasoftmaterial thatdoesnot insulateyouwhenworkingwithlive electricalcurrents. Manycustomershaverubberfloormatsnear theirmachines thatcontainsmall conductivefiberstodecreaseelectrostaticdischarges.Donotusesuchkindofmat toprotectyourselffromelectricalshock.

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.

Lenovo 100e Hardware Maintenance Manual

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 and similar units. (This practice ensures correct grounding of the units.)

If an electrical accident occurs: Caution: do not become a victim yourself. Switch off the power. Send the victim to get medical aid.

About this manual

Safety inspection guide 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 according to the 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.

Lenovo 100e Hardware Maintenance Manual

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. Useproduct-specificESDprocedureswhen theyexceed the requirements

notedhere. 2. Makesurethat theESDprotectivedevicesyouusehavebeencertified(ISO

9000)asfullyeffective.

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 the black side of 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: TheuseofagroundingsystemtoguardagainstESDdamageisdesirablebutnot 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.

Important service information

This chapter presents the following important service information: Strategy for replacing FRUs on page 16

Strategy for replacing a hard disk drive on page 17 Important notice for replacing a system board on page 17

Important information about replacing RoHS compliant FRUs on page 18

Important: BIOSanddevicedriverfixesarecustomer-installable.TheBIOSanddevice driversarepostedonthecustomersupportsite: http://support.lenovo.com.

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 loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, follow the steps below: 1. Go to http://support.lenovo.com. 2. Enter the serial number or select a product or use Lenovo smart

downloading. 3. Select the BIOS/Driver/Applications and download. 4. Follow the directions on the screen and install the necessary software.

17

Important service information

Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: If you are instructed to replace an FRU, but the replacement does not solve

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 of them, and replacing one of them does not solve 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.

Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive. This will cause all customer data on the hard disk to be lost. Make sure that the customer has a current backup of the data before performing this action. 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 can cause damage to those components, and may cause a system malfunction. Attention: When handling a system board: Do not drop the system board or apply any excessive force to it. Avoid rough handling of any kind. Avoid bending the system board and hard pushing to prevent cracking at

each BGA (Ball Grid Array) chipset.

Lenovo 100e Hardware Maintenance Manual

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, replacement parts can also be non-compliant. In all cases if the original FRU parts are RoHS compliant, the replacement part must also be RoHS compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique FRU part numbers.

Lenovo plans to transit to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovos requirements and schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRUs.

RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date, failed RoHS compliant parts must always be replaced with RoHS compliant ones, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs may be used.

Products marketed before June 2006 Products marketed after June 2006 Current or original part

Replacement FRU Current or original part

Note for warranty: 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. The 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:

The following are not covered under warranty: LCD panel cracked from the application of excessive force or from being

dropped Scratched (cosmetic) parts Distortion, deformation, or discoloration of the cosmetic parts Plastic parts, latches, pins, or connectors that have been cracked or broken

by excessive force Damage caused by liquid spilled into the system Damage caused by the improper insertion of a PC Card or the installation of

an incompatible card Improper disk insertion or use of an optical drive Diskette drive damage caused by pressure on the diskette drive cover,

foreign material in the drive, or the insertion of a diskette with multiple labels Damaged or bent diskette eject button Fuses blown by attachment of a nonsupported device Forgotten computer password (making the computer unusable) Sticky keys caused by spilling a liquid onto the keyboard Use of an incorrect AC adapter on laptop products

The following symptoms might indicate damage caused by nonwarranted activities: Missing parts might be a symptom of unauthorized service or modification. If the spindle of a hard disk drive becomes noisy, it may have been subjected

to excessive force, or dropped.

To verify a symptom, follow the steps below: 1. Turn off the computer. 2. Connect the AC adapter. 3. Make sure that power is supplied when you turn on the computer. 4. Turn off the computer. 5. Disconnect the AC adapter. 6. Make sure that the battery pack supplies power when you turn on the

computer.

If you suspect a power problem, see the appropriate power supply checkout: Checking the AC adapter on page 21 Checking operational charging on page 21

Checking the AC adapter You are here because the computer fails only when the AC adapter is used. If the power-on indicator does not turn on, check the power cord of the AC

adapter for correct continuity and installation. If the computer does not charge during operation, go to Checking

operational charging on page 21. To check the AC adapter, follow the steps below: 1. Unplug the AC adapter cable from the computer. 2. Measure the output voltage at the plug of the AC adapter cable. See the

following figure:

Note: Output voltage for the AC adapter pin No. 2 may differ from the one you are servicing. 3. If the voltage is not correct, replace the AC adapter. 4. If the voltage is acceptable, do the following: Replace the system board. If the problem persists, go to Lenovo 100e on page 27. Note: Noise from the AC 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.

22

Lenovo 100e Hardware Maintenance Manual

Perform operational charging. If the battery status indicator or icon is not lit, 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.

Passwords

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. 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.

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 protects the system information stored in the BIOS. The user must enter the supervisor password to get access to the BIOS and change the system configuration.

Attention: If you forget the password, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.
