Diagnostic programs
Diagnostic programs are used to test hardware components of your computer.
Diagnostic programs can also report operating-system-controlled settings that
interfere with the correct operation of your system. There are two programs
preinstalled on your computer to help you diagnose computer problems:
v
Lenovo ThinkVantage Toolbox (used when you are running the Windows
operating system)
v
PC-Doctor for Rescue and Recovery (used when you cannot start the Windows
operating system)
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 71 for
detailed information.

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