If the touch pad doesn’t work

∙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.

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

If you want to use the touch pad again, you must suspend or shut down the computer before you detach the scroll mouse.

∙Test the keyboard and pointing devices with the e-Diagtools diagnostics. See “Testing the Hardware” on page 115.

If the embedded numeric keypad doesn’t work
