Use the following procedures as a guide in identifying and

correcting problems with the ThinkPad computer.

Note: The diagnostic tests are intended to test only IBM

products. The use of non-IBM products, prototype

cards, or modified options can lead to false

indications of errors and invalid system responses.

1. Identify the failing symptoms in as much detail as

possible.

2. Verify the symptoms. Try to re-create the failure by

running the diagnostic test or by repeating the

operation.

Testing the computer

The ThinkPad computer has a test program called

PC-Doctor

DOS (hereafter called PC-Doctor.) You can

detect errors by running the diagnostics test included in

PC-Doctor. This section is an overview of the procedure.

For details that depend on model-unique functions, refer to

“Product overview” on page 43.

For some possible configurations of the computer,

PC-Doctor might not run correctly. To avoid this problem,

you need to initialize the computer setup by use of the IBM

BIOS Setup Utility before you run PC-Doctor. On the IBM

BIOS Setup Utility screen, press F9, Enter, F10, and then

Enter.

Note: When you initialize the computer configuration,

some devices are disabled, such as the serial port.

If you test one of these devices, you will need to

enable it by using PS2.EXE.

PC-Doctor cannot be used to test a device that is in the

docking station, even if the computer supports the docking

station. To test a USB device, connect it to the USB

connector of the computer. To test the Ultrabay device,

install it in the Ultrabay Plus slot of the computer.

To run the test, do as follows:

Note: In the following procedure, you can select an item

not only with the arrow keys, but also with the

TrackPoint. Instead of pressing Enter, click the left

button.

1. Insert the PC-Doctor disk into the diskette drive; then

power on the computer.

If the computer cannot be powered on, go to “Power

system checkout” on page 38, and check the power

sources.
