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: click Start, Control Panel, Printers and Other Hardware,
Mouse (Windows XP), or click Start, Settings, Control Panel, and then double-click
Mouse (Windows 2000).
If the touch pad doesn't work
• Press the touch pad on-off button so the light turns on.
• Don't touch the touch pad while the computer is rebooting or resuming from Standby
mode. If this happens, try the following: press a key on the keyboard to restore
normal operation, or suspend and resume operation using the power button.
• If an external mouse is connected, the built-in pointing devices are normally disabled.
You can change this setting with the BIOS Setup utility—see "To run the BIOS Setup
utility" on page 118.
• Restart the computer: click Start, Turn Off Computer (or Shut Down), Restart.
If the touch pad moves the pointer or cursor while you type
• Press the touch pad on-off button to turn off the touch pad while you type.
If a PS/2 scroll mouse doesn't work
• The touch pad must be disabled for the mouse's 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 "To run the BIOS Setup utility" on page 118.
