Cleaning The Computer And Monitor; Cleaning The Computer Vents; Cleaning The Keyboard And Mouse; Cleaning The Touch Screen (Select Models Only) - HP Computer Troubleshooting And Maintenance Manual

Cleaning the computer and monitor

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.

Cleaning the computer vents

Air vents keep the computer 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.
2.
Remove any debris that has accumulated in and around the computer connectors (for example, the
Ethernet and USB connectors).

Cleaning the keyboard and mouse

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.

Cleaning the touch screen (select models only)

CAUTION: Do not spray or place the cleaner directly on the screen; spray the cleaner into the cloth,
and then wipe the sides and surface of the touch screen.
Do not use an abrasive cleaner or cloth when cleaning the sides or the surface of the screen, because
this could cause damage to the touch screen.
