If these actions do not correct the problem, have the computer and keyboard serviced. See Chapter 11 “Getting information, help, and service” on page 73 for details.

The mouse or pointing device does not work

Symptom: The mouse or pointing device does not work.

Actions:

•Verify that the mouse or pointing-device cable is securely attached to the correct connector on the computer. Depending on the type of mouse you have, the mouse cable will connect to either the mouse, serial, or USB connector. Some keyboards have integrated USB connectors that can be used for a USB mouse or pointing device.

•Verify that the device drivers for the mouse or pointing device are installed correctly.

•If you are using a USB keyboard or mouse, verify that the USB connectors are enabled in the BIOS settings. See “Enabling or disabling a device” on page 45.

If these actions do not correct the problem, run the diagnostic programs (see “Diagnostic programs” on page 69 for instructions). If you need technical assistance, see Chapter 11 “Getting information, help, and service” on page 73.

The pointer on the screen does not move smoothly with the mouse

Symptom: The pointer on the screen does not move smoothly with the mouse.

Action: Erratic movement of the mouse pointer is generally caused by a buildup of dirt, oils, and other contaminants on the ball inside the mouse. Clean the mouse. See “Optical mouse” on page 51 for instructions.

Action: The following could cause the fingerprint reader not to operate properly:
