HP 280 G3 User Manual

●
If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronics supply outlets.
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 conned 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 11.
Cleaning the mouse
Before cleaning the mouse, ensure that the power to the computer is turned o.
●
Clean the mouse ball by rst removing the retaining plate and the ball from the housing. Pull out any
debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
●
To clean the mouse body, follow the procedures in Cleaning the computer case on page 11.
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and software requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
Phillips #2 screwdriver
●
Diagnostics software
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP
strongly recommends that all screws removed during disassembly be kept with the part that was removed,
then returned to their proper locations.
CAUTION: Metric screws have a black nish. U.S. screws have a silver nish and are used on hard drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area
to prevent damage.
