Cleaning System Components
As it draws in air to cool the computer, the power supply fan also draws dust and
other particles into the computer. This contaminant buildup increases the system’s
internal temperature and interferes with component operation.
To minimize these conditions, Dell recommends keeping your work environment
clean. In particular, you should regularly clean your computer system. You may also
want to purchase monitor and keyboard covers to protect against dust and debris.
Recommended Tools and Accessories
Use the following tools and accessories for cleaning the computer system:
•
Wrist grounding strap to reduce the effects of electrostatic discharge (ESD)
•
Liquid dishwashing detergent
•

Cleaning the Computer, Monitor, and Keyboard Exteriors
To clean the exterior of the computer, monitor, and keyboard, perform the following
steps:
1.
Place the strap around your wrist, and attach the other end to an unpainted metal
surface on the back of the chassis.
2.
Turn off the computer, monitor, and any other attached devices, and disconnect
them from their power sources.
3.
Use the vacuum cleaner to remove any dust from the slots and holes on the com-
puter and between the keys on the keyboard.
4.
Moisten a soft cleaning cloth with a solution of three parts water and one part liq-
uid dishwashing detergent.
Do not soak the cloth in the solution; you must not let the solution drip inside the
computer or keyboard.
NOTICE: Do not wipe the monitor screen with this solution. Doing so may
damage the antiglare coating on your monitor screen.

Use the moistened cloth to wipe the computer cover, the keyboard, and the exte-
xte-
