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

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
