PC-Doctor for DOS
You can also download the latest version of the PC-Doctor for DOS diagnostic program from
http://support.lenovo.com. The PC-Doctor for DOS diagnostic program runs independently of the Windows
operating system. Use the PC-Doctor for DOS diagnostic program if you are unable to start the Windows
operating system or if the two diagnostic programs preinstalled on your computer have not been successful
in isolating a possible problem. You can run the PC-Doctor for DOS diagnostic program from a diagnostic
disc that you created.
