HP 100B manual Service Considerations, Cleaning the Monitor, Cleaning the Mouse, Screws

Page 27

If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.

CAUTION: Never remove a wide leveled 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 squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

Cleaning the Monitor

Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for cleaning monitors. 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 flammable liquids on the monitor.

To clean the monitor body follow the procedures in Cleaning the Computer Case on page 18.

Cleaning the Mouse

Before cleaning the mouse, ensure that the power to the computer is turned off.

Clean the mouse ball by first 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 18.

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 (HP screwdriver with bits, PN 161946-001)

Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)

Phillips #2 screwdriver

Diagnostics software

HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper- resistant bits (Smart Cover FailSafe Key, PN 166527-002)

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different 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: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.
