Cleaning the keyboard
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from
under the keys.
If the keyboard has an on/off switch, turn it off.
Follow the safety precautions in the Maintenance and Service Guide for your workstation before
cleaning the computer.
Visible debris underneath or between the keys can be removed by vacuuming or shaking.
Canned, pressurized air can be used to clean debris from under the keys. Use caution because
too much air pressure can dislodge lubricants applied under the wide keys.
If you remove a key, use a specially designed key remover to prevent damage to the keys. This
tool is available from many electronic supply outlets.
CAUTION: Never remove a wide key (like the space bar key) from the keyboard. If these keys
are improperly removed or installed, the keyboard might not function properly.
Clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be careful
not to wipe away lubricants necessary for proper key functions. Allow the parts to air dry before
reassembly.
Use tweezers to remove any fibers or dirt in confined areas.
Cleaning the monitor
Follow the safety precautions in the Maintenance and Service Guide for your workstation before
cleaning the computer.
To clean the monitor, wipe the monitor screen with a towelette designed for cleaning monitors or a
clean cloth moistened with water.
CAUTION: Do not use sprays or aerosols directly on the screen—the liquid might seep into the
housing and damage a component.
Never use solvents or flammable liquids on the monitor because display or housing damage may
result.
