HP 700 G1 Service considerations, Cleaning the monitor, Cleaning the mouse, Power supply fan

Page 24

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 15.

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 15.

Service considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.

Power supply fan

The power supply fan is a variable-speed fan based on the temperature in the power supply.

CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes.

You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

Tools and software Requirements

To service the computer, you need the following:

Torx T-15 screwdriver

Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)

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

Phillips #2 screwdriver

Diagnostics software

Tamper-resistant T-15 wrench
