Cleaning the TouchPad and keyboard
CAUTION: When cleaning the TouchPad and keyboard, do not let liquids drip between the keys.
This can permanently damage internal components.
● To clean the TouchPad and keyboard, use a soft microfiber cloth or chamois moistened with one
of the cleaning solutions listed previously or use an acceptable disposable wipe.
● To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a
can of compressed air with a straw extension.
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.
