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 Configuration utility for DOS. The utility is
available on the following Web site: http://www.lenovo.com/support
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.
Testing the computer
Note:
The PC-Doctor diagnostic CD does not support any optical drives connected through USB devices or
any others. It supports only the internal optical drive of the ThinkPad Notebook.
To run the test, do as follows:
1. Turn off the computer.
2. Make sure that the internal optical drive that is supported as a startup device is attached to the
computer you are servicing.
3. Turn on the computer. If the computer cannot be powered on, go to “Power system checkout” on
page 32, and check the power sources.
If an error code appears, go to “Symptom-to-FRU index” on page 39.
4. When the ThinkPad logo comes up, immediately press F12 to enter the Network Boot menu.
5. Insert the PC-Doctor CD into the internal optical drive.
6. Press cursor keys to select
ATAPI CDx
(x: 0, 1, ...) and then press Enter.
7. Follow the instructions on the screen.
8. The main panel of PC-Doctor appears.
9. Select
Diagnostics
with the arrow keys, and press Enter.
Note:
You can select an item not only with the arrow keys, but also with the TrackPoint
®
pointer.
Instead of pressing Enter, click the left button.
A pull-down menu appears. (Its exact form depends on the model.)
Note:
PC-Doctor menu does not mean the formal support device list. Some unsupported device names
may appear in the PC-Doctor menu.
