A+ Question of the Week: Video Projector

AplusQOW5Why is it a bad idea to unplug a running video projector unit?

A. The operating system might have open file handles.
B. The projector’s fan will be unable to exhaust the residual heat.
C. You must first disconnect the projector from the attached computer.
D. You will not be able to discontinue DualView in Windows.

The correct answer is B.

Projectors need to continue to run their exhaust fan after use. If the projector’s power source is removed before the fan stops on its own, the leftover heat can damage the expensive projector bulb and the projector itself.
