Note: It is important to create a diagnostic CD image or diagnostic diskettes in
case PC-Doctor for DOS cannot be run from the Rescue and Recovery
workspace.
Creating a diagnostic CD image
To create a diagnostic CD image, download a self-starting bootable CD 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
using any CD burning software.
If the computer does not have a CD burner or you do not have Internet access, see
“Creating diagnostic diskettes.”
Creating diagnostic diskettes
To create diagnostic diskettes, download the PC-Doctor for DOS diagnostic
program from http://www.lenovo.com/support/ onto two blank, formatted
diskettes.
If you do not have Internet access, create the diagnostic diskettes using the
following procedure:
Note: You will need a diskette drive on the computer or a USB diskette drive to
complete this procedure.
1. Shut down the operating system and turn off the computer.
2. If you are using a USB diskette drive, plug it into the computer.
3. Repeatedly press and release the F11 key as you turn on the computer.
4. When you hear beeps or see a logo screen, stop pressing the F11 key. The
Rescue and Recovery workspace opens.
Note: For some models, press the Esc key to enter Rescue and Recovery.
5. From the Rescue and Recovery workspace, select Create diagnostic disks.
6. Follow the instructions on the screen.
7. When prompted, insert a blank, formatted diskette into the diskette drive and
continue to follow the instructions on the screen.
8. When the operation is complete, remove the diskette and click Quit.
9. Insert another blank, formatted diskette into the diskette drive and continue to
follow the instructions on the screen.
10. When the operation is complete, remove the diskette and click Quit.
Running diagnostics from the CD or diskettes
1. If you are running diagnostics from diskettes using a USB diskette drive, plug
in the USB drive.
Note: The optical drive or diskette drive must be selected in the startup
sequence. See“Changing the startup device sequence” on page 53 for
instructions on how to select the startup device.
2. Insert the CD or diskette.
3. Restart the computer.
4. When the diagnostics program opens, follow the instructions on the screen.
