Diagnostic programs

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 programs preinstalled on your computer to help you diagnose computer problems:

•Lenovo ThinkVantage Toolbox (used when you are running the Windows operating system)

•PC-Doctor for Rescue and Recovery (used when your Windows operating system does not start)

Notes:

1.You can also download the PC-Doctor for DOS diagnostic program from http://www.lenovo.com/support. See “PC-Doctor for DOS” on page 49 for detailed information.

2.If you are unable to isolate and repair the problem yourself after running the diagnostic programs, save and print the log files created by the diagnostic programs. You will need the log files when you speak to a Lenovo technical support representative.
