Using an optional external numeric keypad
Keys on most external numeric keypads function differently according to whether num lock is on or off.
(Num lock is turned off at the factory.) For example:
●When num lock is on, most keypad keys type numbers.
●When num lock is off, most keypad keys function like the arrow, page up, or page down keys.
When num lock on an external keypad is turned on, the num lock light on the computer is turned on.
When num lock on an external keypad is turned off, the num lock light on the computer is turned off.

4 Cleaning the TouchPad and keyboard
Dirt and grease on the TouchPad can cause the pointer to jump around on the screen. To avoid this,
clean the TouchPad with a damp cloth, and wash your hands frequently when using the computer.
WARNING! To reduce the risk of electric shock or damage to internal components, do not use a
vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on
the keyboard surface.
Clean the keyboard regularly to prevent keys from sticking and to remove dust, lint, and particles that
can become trapped beneath the keys. A can of compressed air with a straw extension can be used to
blow air around and under the keys to loosen and remove debris.
