SSC MTS EXAM

Detailed explanation-1: -The built-in fan absorbs the air around the computer and if the computer has not had a cover, dust will be sucked into the fan and into the computer. This in time can cause problems with the fan, because each build-in fan has a filter which will collect dust if a cover is not used.

Detailed explanation-2: -It is not a good idea to cover a laptop with cloth as the keyboard in a lot of them is used as a vent to help circulate air through the case . Static electricity is a possibility but unless there is a touch screen on the laptop it has little effect and is protected .

Detailed explanation-3: -The computer’s fan will go on trying to cool the computer but if computer is covered by a blanket the fan energy will just cause over heating sooner. If you use a blanket to block your computer’s ventilation you will cause heat to build up and most likely it will power itself down (due to CPU overheating).
