Tip
Foam swabs or cosmetic
applicators are preferred
to cotton swabs because
cotton can add rather
than remove lint.
Tip
Give your Presario Notebook a
safe home. If your Notebook is
consistently exposed to direct
sunlight, consider moving it.
The heat from the sun shining
on the display screen can
reduce its performance and
cause glare.
Warning
Always disconnect the
power from your Notebook
and disconnect any other
peripherals before attempting
to clean your Notebook or
any of its components.
The surface of your display screen may look fuzzy or smudged.
You can use a soft, damp, lint-free cloth to wipe the screen
clean.
If the display screen requires any additional cleaning, use an
antistatic screen cleaner or pre-moistened antistatic wipes.
Grease and dirt on the TouchPad
can cause your cursor to jump
around on the display screen.
To avoid this, periodically clean
the TouchPad with a damp cloth.
Remember, before using your
Notebook, always wash your
hands if they are dirty.
