• Reset the device by detaching and reattaching the USB connector.
If these actions do not correct the problem, run the diagnostic programs to test the USB connector (see
“Diagnostic programs” on page 107 for instructions). If the USB device came with its own diagnostics, run
those diagnostics against the USB device. If you need technical assistance, see Chapter 11 “Getting
information, help, and service” on page 109.
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 Lenovo ThinkVantage Toolbox program to diagnose computer problems, if your
computer is running 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 107 for detailed information.
2. If you are unable to isolate and repair the problem yourself after running the programs, save and print
the log les created by the programs. You will need the log les when you speak to a Lenovo technical
support representative.
