HP 23-Q120 Benutzeranleitung

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.

To prevent damage to internal components, do not allow liquids to drip between the keys.

●

To clean the 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.

If you have a roller-ball mouse, clean the ball and rollers inside.

Turn the mouse upside down, and rotate the ball-cover ring counterclockwise to remove the ring and 

release the roller ball.

Rinse the roller ball with soap and warm water.

Clean the rollers inside the mouse with a cotton swab dampened with isopropyl (rubbing) alcohol.

After the roller ball and rollers are completely dry, replace the ball and ball-cover ring.
