Toverifyasymptom, dothefollowing:

1. Turnoff the computer.
   2.Removethebatterypack.
2. ConnecttheACadapter.
3. Check that power is supplied when you turn on the computer.
4. Turnoff the computer.
   6.DisconnecttheACadapterandinstallthechargedbatterypack.
5. Check that the battery packs supplies power when you turn on the computer.

If you suspect a power problem, se the appropriate one of the following power supply checkouts:

• "CheckingtheACadapter"
• "Checkingoperationalcharging" on page 42
• "Checkingthebatterypack" on page42
• "Checkingthebackupbattery" on page 43

CheckingtheACadapter

You are here because the computer fails only when the AC adapter is used.

• If the power problem occurs only when the docking station or the port replicator is used, replaced docking station or the port replicator.
• 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, goto "Checking operational charging" on page 42.

TochecktheACadapter,dothefollowing:

1. UnplugtheACadaptercablefromthecomputer.
2. Measure the output voltage at the plug of the AC adapter cable. See the following figure:

(20V)

PinVoltage(Vdc)
1+20
2	0
3Ground

Note: Output voltage of pinno.2 of the AC adapter may different from the one you are servicing.

1. If the voltage is not correct, replace the AC adapter.

2. If the voltage is acceptable, do the following:

•Replacethesystemboard.

- If the problem persists, goto "FRU tests" on page 39.

Note: Noise from the AC adapter does not always indicate a defect.

Checkingoperationalcharging

To check whether the battery charges properly during operation, use discharged battery pack or battery pack that has less than 50% of the total power remaining when installed in the computer.

1. Run the diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, donot replace any FRUs.
3. If any error is detected, replace the FRU shown by the FRU code. Rerunthe test to verify that nomore error sexist.

Undeterminedproblems

If the diagnostic tests did not identify the adapter or device that has failed, if wrong devices are installed, or if the system simply is not operating, follow these procedure to isolate the failing FRU (donotisolate FRU sthathavenodefects).

Verify that all attached devices are supported by the computer.

Verify that the powersupply being used at the time of the failure is operating correctly. (See "Powersystemcheckout" on page 41.)

Restoring the serial number of the system unit

When the computer was manufactured, the EEPROM Monthesystemboard was loaded with the serial numbers of the system and all major components. These numbers need to remain the same throughout the life of the computer.

If youreplacethesystemboard, you must restore the serial number of the system unit to its original value.

Before replacing the system board, save the original serial number by doing the following:

1. InstalltheLENOVOThinkPadHardwareMaintenanceDisketteVersion1.76or later, and restart the computer.
2. From themainmenu, select 1. Set System Identification.
3. Select2. ReadS/NdatafromEEPROM.

The serial number of each device in your computer is displayed; the serial number of the system unit lists as follows:

•20:Serialnumber

Writedownthatnumber.

Note: Theserialnumberofthesystemunitisalsowrittenonthelabelattachedto thebottomofthecomputer.

Afteryouhavereplacedthesystemboard,restoretheserialnumberbydoingthe following:

1. InstalltheLENOVOThinkPadHardwareMaintenanceDisketteVersion1.76or laterandrestartthecomputer.
2. From themainmenu, select 1. Set System Identification.
3. Select1.AddS/NdatafromEEPROM.

Followtheinstructionsonthescreen.

If the MT Mand Product ID numbers differ from each other on there are label, use what is shown for the Product ID field. See example below:

MTMonrearlabel:

TTTT-CTOS/NSSSSSSS

ProductIDonrearlabel:

TTTT-MMM(UsethisnumberwhensettingSerialNumber)

Intheexample,theSerialNumbertobeinputis'1STTTTMMMSSSSSSS'.

RetainingtheUUID

The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to your computer at production and stored in the EEPROM of your system board.

The algorithm that generates the number of designed to provide unique IDs until the year A.D.3400. Not wocomputers in the world have the same number.

Whenyoureplacethesystemboard,youmustsettheUUIDonthenewsystem boardasfollows:

1. InstalltheLENOVOThinkPadHardwareMaintenanceDisketteVersion1.76or later, and restart the computer.

2. From themainmenu, select 4. Assign UUID.

AnewUUIDiscreatedandwritten. If a valid UUIDal ready exists, it is not overwritten.
