Keeping the computer free of dust, dirt, and heat
Keeping your computer system free of dust, dirt, and heat will prolong its life. Dust, pet hair, and other particles can
build up, creating a blanket effect; as a result, components can overheat, or, in the case of the keyboard and mouse,
not work smoothly and effectively. Check your system once a month for visible signs of dust and debris, and clean it
about once every three months. Visit www.hp.com/support for additional cleaning instructions.

ENWW
Use CD or DVD recording software that is installed on your computer to create (or "burn")
backup discs of important information, including personal files, e-mail messages, and Web
site bookmarks. You can also move data to an external hard disk drive.
Air vents keep the computer and monitor cool. Keep these vents clean by using a small,
battery-powered vacuum cleaner. (A battery-powered vacuum cleaner eliminates the
risk of electric shock.)
1.
Vacuum the vents on the computer case and the monitor case.
2.
Remove any debris that has accumulated in and around the computer connectors
(for example, the Ethernet and USB connectors).
Follow these steps to clean the computer and monitor:
1.
Unplug the power to the computer and the monitor.
2.
To clean the monitor screen, use a clean, dry cloth. Do not use water on the
monitor screen. For more thorough cleaning, use a clean cloth and antistatic
screen cleaner.
3.
Use a clean, dry cloth to dust the computer case and the monitor case.
NOTE:
To remove sticker residue or a spill on the computer or monitor case,
use isopropyl (rubbing) alcohol and a lint-free cloth.
When cleaning the keyboard keys, use a low setting on a battery-powered vacuum
cleaner, to avoid removing key caps and springs.
1.
Vacuum between the keys of the keyboard and along the grooves.
2.
Use a clean, dry cloth and isopropyl (rubbing) alcohol to clean buildup on the
keyboard keys and along its edges.
3.
Wipe the body of the mouse and the mouse cord by using cleaning wipes.
If you have a roller-ball mouse, clean the ball and rollers inside:
1.
Turn the mouse upside down, and rotate the ball-cover ring counterclockwise to
remove the ring and release the roller ball.
2.
Rinse the roller ball with soap and warm water.
3.
Clean the rollers inside the mouse with a cotton swab dampened with isopropyl
(rubbing) alcohol.
4.
After the roller ball and rollers are completely dry, replace the ball and ball-cover
ring.
