Cooling vents
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.
