The HP Digital Entertainment Center is a high-quality 
device that requires special care when cleaning. To clean 
the HP Digital Entertainment Center, follow these steps:

Turn off the HP Digital Entertainment Center and 
connected equipment.

Unplug the HP Digital Entertainment Center from the 
wall outlet before cleaning. 

Use a soft dry cloth for dusting.

Use a clean cloth dampened with warm water to 
wipe it clean. If sticker residue is present, use 
isopropyl alcohol or rubbing alcohol and a lint-free 
cloth to remove the residue.

Use a battery-powered vacuum to remove dust and 
buildup from the vents and the I/O ports on the sides 
and back of the system.

Plug in the HP Digital Entertainment Center.

Turn on connected equipment and the HP Digital 
Entertainment Center.

Debris particles and oil can accumulate on, between, and 
beneath the keys of your keyboard and trackball. 

Gently use a small battery-powered vacuum to 
remove debris particles that get between and 
beneath the keyboard keys. Use a low setting to 
avoid removing key caps and springs.

Use a clean, dry cloth and isopropyl alcohol to clean 
the buildup on the keyboard keys.

Rotate the trackball-cover ring counter-clockwise to 
remove the ring and release the trackball.

Rinse the trackball and cover ring with soap and 
warm water. Dry them with a lint-free cloth.

Clean the rollers for the trackball with a cotton swab 
dampened with isopropyl alcohol. 

Replace the trackball and trackball-cover ring.
