CAUTION: Never remove a wide, level key (like the space bar) from the keyboard. If these keys are
improperly removed or installed, the keyboard may not function properly.
●
Cleaning under a key may be done with a swab moistened with isopropyl alcohol and then squeezed out.
Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any
bers or dirt in conned areas. Allow the parts to air dry before reassembly.
Cleaning the monitor
●
Wipe the monitor screen with a towelette designed for cleaning monitors or with a clean cloth moistened
with water. Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and
damage a component. Never use solvents or
ammable liquids on the monitor.
●
To clean the monitor body follow the procedures in Cleaning the computer case on page 13.
Service considerations

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP

returned to their proper locations.

prevent damage.
