Cleaning the TouchPad and keyboard
Dirt and grease on the TouchPad 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 deposits household debris on the
keyboard surface.
Clean the keyboard regularly to prevent keys from sticking and to remove dust, lint, and particles that
become trapped beneath the keys. A can of compressed air with a straw extension can blow air around
and under the keys to loosen and remove debris.
