Lenovo ThinkPad T61 Hardware Maintenance Manual page 31

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 BIOS Setup Utility before you run PC-Doctor. On the 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 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 ThinkPad Advanced Dock,
even if the computer supports the ThinkPad Advanced Dock. To test a USB device,
connect it to the USB connector of the computer.
Creating the PC-Doctor diagnostics diskette
To create the PC-Doctor disk from the Rescue and Recovery workspace, do as
follows:
1. Enter the Rescue and Recovery workspace by pressing the ThinkVantage button
during POST.
2. When the Rescue and Recovery workspace finishes loading, click Diagnostic
Diskette.
3. Authenticating the digital signature takes about 15 seconds; then the ThinkPad
computer will reboot into PC-DOS.
4. A batch file automatically starts up to prompt you through the process of
creating diskettes. You are notified of how many diskettes you will need.
a. You are prompted to insert each diskette in sequence.
b. Typically, all you need to do is to press the Enter key for the floppy drive;
the system then formats and creates the diskette.
c. Each diskette is erased and formatted with the PC-Doctor for DOS boot
image.
5. Once all the diskettes have been created, the ThinkPad computer will reboot.
The user is asked to remove all diskettes from the drive, or to insert the first
diskette created if it is desired to run the diagnostics.
Testing 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 pointer. 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
26, and check the power sources.
If an error code appears, go to "Symptom-to-FRU index" on page 35.
On the first screen, select the model and press Enter. Follow the instructions on
the screen.
2. The main panel of PC-Doctor appears.
3. Select Diagnostics with the arrow keys, and press Enter.
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.
