alcohol, methylene chloride, or any petroleum-based materials, such as gasoline, paint thinner, benzene,
or toluene.
IMPORTANT: To avoid damaging the surface, avoid abrasive cloths, towels, and paper towels.
4. Wipe the exterior of the product gently with the moistened cloth.
IMPORTANT: Keep liquids away from the product. Avoid getting moisture in any openings. If liquid
makes its way inside your HP product, it can cause damage to the product. Do not spray liquids directly
on the product. Do not use aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide
or bleach that might damage the nish.
5. Start with the display (if applicable). Wipe carefully in one direction, and move from the top of the
display to the bottom. Finish with any exible cables, like power cord, keyboard cable, and USB cables.
6. Be sure that surfaces have completely air-dried before turning the device on after cleaning.
7. Discard the gloves after each cleaning. Clean your hands immediately after you remove the gloves.
Cleaning the computer case
Follow all safety precautions before cleaning the computer case.
To clean the computer case, follow these procedures:
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth
or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed because the alcohol evaporates
quickly and does not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the
airow.
Cleaning the keyboard
Use this information to properly clean the keyboard. Follow all safety precautions before cleaning the
k
eyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer
case on page 16.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 14
before following these procedures.
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the
keys.
● You can remove visible debris underneath or between the keys by vacuuming or shaking.
● You can use canned, pressurized air to clean debris from under the keys. Use caution because too much
air pr
essure can dislodge lubricants applied under the wide keys.
