Cleaning the Display

To remove smudges and lint, frequently clean your display with
a soft, damp, lint-free cloth. If the screen requires additional
cleaning, use an antistatic screen cleaner or pre-moistened
antistatic wipes.
Ä
CAUTION: Never spray water, cleaning fluids, or chemicals on the
screen. This can permanently damage your notebook.

Cleaning the TouchPad

Grease and dirt on the TouchPad can cause your cursor to
jump around on the display screen. To avoid this, wash hands
frequently when using the notebook and clean the TouchPad with
a damp cloth.
