Checking the Backup Battery

1. Power off the computer and unplug the AC Adapter from the computer.
2. Open the keyboard and remove the battery pack.
3. Lift the right-hand section of the black insulator sheet.
4. Locate the backup battery on the system board, shown at 1.
   
   
   Do not use a metal tool when removing the backup battery. Use only a plastic tool.
5. Using a plastic tool, remove the backup battery from the system board.
6. Measure the voltage of the backup battery. Refer to the following table for voltages:

   Wire	Voltage (Vdc)
   +	+2.5 to +3.7
   -	Ground

• If the voltage is correct, replace the system board.
• If the voltage is not correct, the backup battery has been  discharged. Replace the backup battery.
• If the backup battery discharges quickly after replacement,  replace the system board.

Checking the Battery Pack

Battery charging will not start until the Fuel-Gauge shows that less than 95% of the total power remains, with this condition the battery pack will charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life.

Do the following:

1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 2 (+) and 6 (-).
   

   Terminal	Voltage (Vdc) / Signal
   1	-
   2	+8 to +13.5
   3	-
   4	-
   5	Thermal
   6	Ground (-)

   NOTE: Signal lines, not used in these steps, are used for communication between the system and the battery.

   • If the voltage is less than +9.6 V dc, the battery pack has been discharged. Recharge the battery pack.

   If the voltage is still less than +9.6 V dc after recharging, replace the battery.

   NOTE: If the voltage of the battery pack is 0 V, it is not defective.

   • If the voltage is more than +9.6 V dc, measure the resistance between battery terminals 5 and 6. The resistance must be 4 K to 30 K ohm.

     If the resistance is not correct, replace the battery pack.

     If the resistance is correct, replace the system board.

1020 Battery Pack

  Be careful that the computer does not fall backward when the battery pack is removed.

2. Connect the AC Adapter and check that power is supplied.
3. Disconnect the AC Adapter and install the charged battery pack, then  check that power is supplied by the battery pack.

If you suspect a power problem, see the appropriate power supply check listed below.

Checking the AC Adapter

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

• If the power problem occurs only when a Port Replicator is used,  replace the 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 operational charge does not work, go to 'Checking Operational Charging' .

NOTE: For Model 365XD, there are two types of adapters. The procedure for checking both types is the same.

1. Unplug the AC Adapter cable from the computer and  measure the output voltage at the plug of the AC Adapter cable.

   

Pin	Voltage (Vdc)
1	+14.5 to +17.0
2	Ground

• If the voltage is correct,  replace the system board.
• If the problem is not corrected, go to 'Undetermined Problems' .
• If the voltage is not correct, go to the next step.
• Unplug the AC Adapter cable from the ac power outlet and wait  five minutes or longer to allow the over-voltage protection circuit  to be fully discharged and initialized.
• Plug the AC Adapter cable into the ac power outlet.
• Measure the output voltage of the AC Adapter.
• If the voltage is still not correct, replace the AC Adapter.

NOTE: An audible noise from the AC Adapter does not always indicate a defective adapter.

Checking Operational Charging

To check operational charging, 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 does not turn on, remove the battery pack and leave it to return to room temperature. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack.

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

• If the power problem occurs only when the Port Replicator is used,  replace the 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 operational charge does not work, go to 'Checking Operational Charging' .

1. Power off the computer
2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 4 (-).
   

   Terminal	Voltage (Vdc) / Signal
   1	+0 to +13.5
   2	N/C
   3	Thermal
   4	Ground (-)
   5	Select
   6	A-Ground

   NOTE: Signal lines not used in these steps are used for communication between the system and the battery.
   • If the voltage is less than +11.0 Vdc, the battery pack has been discharged. Recharge the battery pack.

   If the voltage is still less than +11.0 Vdc after recharging, replace the battery.

   NOTE: If the voltage of the battery pack is 0 V, it is not defective.

   • If the voltage is more than +11.0 Vdc, measure the resistance between battery terminals  3 and 4. The resistance must be 4 to 30 K ohm.

     If the resistance is not correct, replace the battery pack.

     If the resistance is correct, replace the subcard.

1. Power off the computer and unplug the AC Adapter from the computer.
2. Turn the computer upside down.
3. Remove the DIMM cover and backup battery (see DIMM Card / Backup Battery)

Keyboard/Auxiliary Input Device Checkout

Remove the external keyboard if the internal keyboard is to be tested.

If the internal keyboard does not work or an unexpected character appears, make sure that the three flexible cables extending from the keyboard are correctly seated in the connectors on the keyboard card.

If the keyboard cable connections are correct, you can run on TP-2635 the - Keyboard Test by doing the following:

1. Go to the diagnostic menu screen by selecting Test in the Easy-Setup screen.
2. Press Ctrl+A. The ThinkPad FRU Connections screen appears. (If the Ctrl+A does not work, triple-click on the icon on the right bottom corner on the basic diagnostic screen.)
3. Make sure that the keyboard connection is Connected, then press Esc to escape the screen.
4. A layout of the keyboard appears on the screen. Check that when each key is pressed, the key's position on the keyboard layout on the screen changes to a black square. NOTE: When a Fn key is pressed, a black square briefly appears.
5. Press Ctrl+Pause to end the test.

If the test detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a nondefective FRU

• Reseat the keyboard flexible cable.
• Replace the keyboard assembly.
• Replace the subcard
• Replace the system board.

Diskette Drive Test

Do the following to isolate the problem to a controller, drive, or diskette. A scratch, write enabled, non-defective 2HD diskette is required.

FDD-1 represents the built-in diskette drive for 365X. FDD-2 represents a diskette drive in the Port Replicator or a diskette drive attached through the external diskette drive connector.

  Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or can cause the drive to fail.

Do the following to select the test device:

1. Select the advanced diagnostics mode and  select Tool , then  select the FDD-1 or FDD-2 icon and  press the spacebar.  A OK mark appears next to the selected icon.  Insert a blank diskette when instructed.
2. Run the diskette drive test.
3. If the controller test detects an error, FRU code 10 appears.  Replace the system board.
4. If the controller test runs without errors,  the drive read/write tests start automatically.
5. If the drive test detects an error, FRU code 50 for FDD-1  or 51 for FDD-2 appears.  If the diskette itself is known to be good, replace the drive.

1070 Keyboard Unit

When replacing the keyboard unit, connect the keyboard connector as shown in the figure, then replace the keyboard.

 

  Some TP 365X / 365XD will have problems with the Keyboard Position Sensor Switch failing to properly actuate when the keyboard is lowered into normal usage position. (Cause: enter HIBERNATION mode)

Spacers should be affixed to the underside of the keyboard to ensure that the switch is depressed when keyboard is lowered. More than one spacer (incl. in FRU P/N 39H7105) can be affixed to overcome this problem.

Memory Checkout

DIMM cards are available for increasing memory capacity.

DIMM	Displayed Value 2625 365X, XD	Displayed Value 2635 380-385
No DIMM installed	7808KB	16000KB
8MB	16000KB	24192KB
16MB	24192KB	32384KB
32MB	40576KB	48768KB

Memory errors might stop system operations, show error messages on the screen, or hang the system.

Use the following procedure to isolate memory problems.

NOTE: Make sure that the DIMM is fully installed into the connector. Both latches must be latched completely. A loose connection can cause error code 195.

1. Power off the computer and remove the DIMM from its  slot (if installed).
2. Press and hold the F1 key, then power on the computer.  Hold the F1 key down until the Easy-Setup screen appears.

5. Power off the computer and reinstall the DIMM, then power on the  computer. Verify the memory size, then test the memory. If an error  appears, replace the DIMM.

If memory problems occur intermittently, make sure the DIMM socket latches are latched completely. If the DIMM latches are securely latched, use the loop option to repeat the test. When the test detects an error, an error log is printed on the printer connected to the parallel port.

• For 2625 365X, XD see 'Error Log'
• For 2635 380-385 see 'Error Log'

for more information.

Checking the Installed Devices List

If a device is installed but the icon appears in a gray shade rather than a dark shade on the basic diagnostics screen, the device is defective. Reseat the device connectors. If the symptom remains, replace the device or the system board. If needed, adjust the contrast control to clearly distinguish the shade of the icon.

If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when NO second FDD is installed), do the following:

1. Replace the first device in the configuration, such as the FDD-1.
2. If the problem remains, replace the system board.

The PCMCIA, Parallel, and Serial icons are always displayed in a dark shade because the icons represent subsystems of the system board and not the actual attachment of the devices.

The FDD-1 icon represents the first drive in the system configuration. Similarly, the FDD-2 icon represents the second drive, attached to the external diskette drive connector or through a Port Replicator.

Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow the procedures below to isolate the failing FRU (do not isolate non-defective FRUs).
