PC-Doctor for Windows
PC-Doctor for Windows is a diagnostic program that works through the Windows
operating system. The PC-Doctor for Windows diagnostic program enables you to
view symptoms and solutions for computer problems, access the Lenovo
troubleshooting center, update system drivers, and review system information.
To run PC-Doctor for Windows, open the Start menu from the Windows desktop,
select All Programs, select PC-Doctor for Windows, and click PC-Doctor for
Windows. Follow the instructions on the screen. For additional information about
running the diagnostic program, refer to the PC-Doctor for Windows help system.
If you still suspect a problem after PC-Doctor for Windows runs successfully, run
PC-Doctor for DOS or PC-Doctor for Windows PE to help you diagnose the
computer problem.
PC-Doctor for DOS
Depending upon your machine type and model, you either have
PC-Doctor for DOS or PC-Doctor for Windows PE on each Lenovo computer. The
PC-Doctor for DOS diagnostic program is part of the Rescue and Recovery
workspace and runs independently of the Windows operating system. Use
PC-Doctor for DOS, if you are unable to start the Windows operating system or if
PC-Doctor for Windows has not been successful in isolating a possible problem.
You can run PC-Doctor for DOS from a diagnostic CD image or diagnostic
diskettes that have been created. You can also run PC-Doctor for DOS from the
Rescue and Recovery workspace.
