USB problems
Symptom: The USB connectors cannot be accessed.
Actions:
• Ensure that the USB cable is securely connected to the USB connector and to the USB device. If the USB
device has its own power cord, ensure that it is attached to a properly grounded electrical outlet.
• If the USB device has its own On/Off switch, ensure that it is in the On position.
• If the USB device has an Online switch, ensure that it is in the Online position.
• If the USB device is a printer, ensure that paper is loaded correctly.
• Ensure that 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 Lenovo Solution Center program to test the USB
connector. 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 119.
