those diagnostics against the USB device. If you need technical assistance, see Chapter 11 "Getting
information, help, and service" on page 111.
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 computer.
You can use the preinstalled diagnostic program to diagnose computer problems, if your computer is
running the Windows operating system.
Notes:
1. Depending on the date when your computer was manufactured, your computer is preinstalled with
either the Lenovo Solution Center program or the Lenovo ThinkVantage Toolbox program for diagnostic
purposes. For more information about the Lenovo ThinkVantage Toolbox program, see Lenovo
ThinkVantage Toolbox. For more information about the Lenovo Solution Center program, see "Lenovo
Solution Center" on page 109.
2. You can also download the PC-Doctor for DOS diagnostic program from http://www.lenovo.com/support.
See "PC-Doctor for DOS" on page 110 for detailed information.
3. 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.
