You

should inspect your desktop computer for dust accumulation at least once

every three months. Before inspecting your computer, turn off the power and

unplug the computer’s power cord from the electrical outlet; then remove any

dust from vents and perforations in the bezel. If you notice external dust

accumulation, you should also examine and remove dust from the inside of the

computer including heat sink inlet fins, power supply vents, and fans. Always

turn off and unplug the computer before opening the cover. If possible, avoid

operating your computer within 2 feet of high-traffic areas. If you must operate

your computer in or near a high-traffic area, you should inspect and, if

necessary, clean your computer more frequently.

For your safety and to maintain optimum computer performance, always

follow these basic precautions with your desktop computer:

v Keep the cover closed whenever the computer is plugged in.

v Regularly inspect the outside of the computer for dust accumulation.

v Remove dust from vents and any perforations in the bezel. More frequent

cleanings might be required for computers in dusty or high-traffic areas.

v Do not block or restrict airflow into the front of the computer.

v Do not block the airflow vents on the back of the computer.

v Do not store or operate your computer inside furniture, as this might

increase the risk of overheating.

v Airflow temperatures into the computer should not exceed 35° C (95° F).

v Do not use non-ThinkCentre air filtration devices.

CD and DVD drive safety

CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or

otherwise physically damaged, it is possible for the disc to break apart or even

shatter when the CD drive is in use. To protect against possible injury due to

this situation, and to reduce the risk of damage to your machine, do the

following:

v Always store CD/DVD discs in their original packaging

v Always store CD/DVD discs out of direct sunlight and away from direct

heat sources

v Remove CD/DVD discs from the computer when not in use

v Do not bend or flex CD/DVD discs, or force them into the computer or their

packaging

v Check CD/DVD discs for cracks before each use. Do not use cracked or

damaged discs
