PC-Doctor for Windows PE
The PC-Doctor for Windows PE diagnostic program is part of the Rescue and
Recovery
®
workspace on each Lenovo computer. Use the PC-Doctor for Windows
PE if you are unable to start the Windows operating system or if the Lenovo
System Toolbox has not been successful in isolating a possible problem.
Running diagnostics from the Rescue and Recovery
workspace
You can run the PC-Doctor for Windows PE diagnostic program from the Rescue
and Recovery workspace. To run diagnostics from the Rescue and Recovery
workspace, use the following procedure:
1. Shut down the operating system and turn off the computer.
2. Repeatedly press and release the F11 key when you turn on the computer.
3. When you hear beeps or see a logo screen, stop pressing the F11 key. The
Rescue and Recovery workspace opens.
4. From the Rescue and Recovery workspace, select Launch Advanced Rescue
and Recovery → Diagnose hardware.
5. The diagnostic program opens automatically. Select the diagnostic test you
want to run. Press the F1 key for additional help.
6. Follow the instructions on the screen.
Note:
The rescue media includes the PC-Doctor for Windows PE. For more
information about the rescue media, see “Recovering software” in your ThinkCentre
User Guide.
PC-Doctor for DOS
Depending upon your machine type and model, you have either the PC-Doctor for
DOS or the PC-Doctor for Windows PE on your Lenovo computer. The PC-Doctor
for DOS diagnostic program runs independently of the Windows operating system.
Use the PC-Doctor for DOS, if you are unable to start the Windows operating
system or if the PC-Doctor for Windows has not been successful in isolating a
possible problem. You can run the PC-Doctor for DOS from a diagnostic CD/DVD
image that you create.
Creating a diagnostic CD/DVD image
To create a diagnostic CD/DVD image, download a self-starting bootable
CD/DVD image (known as an .iso image) of the diagnostic program from
http://www.lenovo.com/support. After you download the image, you can create
the CD/DVD using any CD/DVD burning software.
Running diagnostics from the disc
To run diagnostics from the diagnostic CD/DVD image that you created, do the
following:
1. Make sure the optical drive you want to use is set as the first boot device in the
startup device sequence. See “Selecting a startup device” on page 51.
2. Make sure the computer is turned on and then insert the disc into the optical
drive.
3. Turn the computer off and back on again. When the diagnostics program
opens, follow the instructions on the screen.
