USB problems

Symptom: The USB connectors cannot be accessed.

Actions:

Make sure the USB cable is securely connected to the USB connector and to the USB device. If the USB device has its own power cord, make sure it is attached to a properly grounded electrical outlet.

If the USB device has its own On/Off switch, make sure it is in the On position.

If the USB device has an Online switch, make sure it is in the Online position.

If the USB device is a printer, make sure paper is loaded correctly.

Make sure any device drivers or other software supplied with the USB device is correctly installed. Refer to the documentation for the USB device.

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 108 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 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” on page 109. For more information about the Lenovo Solution Center program, see “Lenovo Solution Center” on page 108.

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 109 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.
