CAUTION: Avoid strong cleaning solvents that can permanently damage your computer. If you are not sure
that a cleaning product is safe for your computer, check the product contents to be sure that ingredients such
as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons are not included in the
product.
Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and cleaning
agents can get trapped in the scratches.
Cleaning procedures
Follow the procedures in this section to safely clean your computer.
WARNING! To prevent electric shock or damage to components, do not attempt to clean your computer
while it is turned on.
●
Turn off the computer.
●
Disconnect AC power.
●
Disconnect all powered external devices.
CAUTION: To prevent damage to internal components, do not spray cleaning agents or liquids directly on
any computer surface. Liquids dripped on the surface can permanently damage internal components.
Cleaning the display (All-in-Ones or Notebooks)
Gently wipe the display using a soft, lint-free cloth moistened with an alcohol-free glass cleaner. Be sure that
the display is dry before closing the display.
Cleaning the sides or cover
To clean the sides or cover, use a soft microfiber cloth or chamois moistened with one of the cleaning
solutions listed previously or use an acceptable disposable wipe.
NOTE: When cleaning the cover of the computer, use a circular motion to aid in removing dirt and debris.
Cleaning the TouchPad, keyboard, or mouse
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.
CAUTION: To prevent damage to internal components, do not allow liquids to drip between the keys.
●
To clean the TouchPad, keyboard, or mouse, use a soft microfiber cloth or a 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.
