Cooling
1. Clean any dust accumulated on the computer's cooling vents.
The cooling vents are located on the back and underside of the
computer.
When you use your computer in a dusty area, dirt and debris may
accumulate on the cooling vents at the under side of your unit. If this
occurs, the accumulated dust can cause insufficient heat dissipation which
may result in the computer shutting down during use. Carefully clean the
dust from the vents using a vacuum cleaner.
2. Cooling vents on the underside and back of the computer.
The above illustration is of the subwoofer equipped model. Models without
the subwoofer have cooling vents in the subwoofer location pictured
above. Models with the subwoofer do not have cooling vents in the
subwoofer location pictured above.
