Diagnostic programs are used to test hardware components of your computer and report operating-system-controlled settings that can cause hardware failures. There are two diagnostic programs preinstalled on your computer to help you diagnose problems: PC-Doctor for Windows and PC-Doctor for DOS.

Notes:

1.You can download the latest version of the diagnostic programs from http://www.lenovo.com/support/. Type your machine type into the Use Quick Path field and click Go to find the downloadable files that are specific to your computer.

2.If you are unable to isolate and repair the problem yourself after you run PC-Doctor for Windows and PC-Doctor for DOS, save and print the log files created by both diagnostic programs. You will need the log files when you speak to a Lenovo technical support representative. (The log file created by PC-Doctor for Windows is automatically saved in C:\PCDR\DETAILED.TXT.)
