Keyboard and pointing device problems

Use these suggestions for built-in or external devices.

If the pointer is difficult to control

Adjust the pointer controls. Select Start > Control Panel > Printers and Other Hardware > Mouse.

If the TouchPad doesn’t work

•Press the TouchPad on-off button to turn on the light.

•Don’t touch the TouchPad while the notebook is rebooting or resuming from Standby mode. If this happens, try the following: press a key on the keyboard to restore normal operation.

•If an external mouse is connected, the built-in pointing devices are normally disabled. You can change this setting with the BIOS Setup utility.

•Restart the notebook. Select Start > Turn Off Computer > Restart.

If the TouchPad moves the pointer or cursor while you type

Press the TouchPad on-off button to turn off the TouchPad while you type.

If a PS/2 scroll mouse doesn’t work

•The TouchPad must be disabled for the mouse scroll feature to work. In the BIOS Setup utility, make sure the External Pointing Devices option in the System Devices menu is set to Auto. See “Configuring the Notebook” in this chapter.

•Suspend or shut down the notebook before you attach the scroll mouse, so that it will be detected properly.

If you want to use the TouchPad again, you must suspend or shut down the notebook before you detach the scroll mouse.
