If an external mouse doesn't work • Standby or shut down the computer before you attach the mouse, to ensure that it will be detected properly. If you want to go back to using the touch pad, you must standby or shut down the computer before you detach the mouse. If the embedded numeric keypad doesn't work • Make sure Num Lock is on-that you have pressed Fn+F8 to activate the numeric keypad and that you have pressed the Lock key to turn on number lock. • Don't touch the touch pad while booting or resuming-see above.
