Our Helproom expert explains how to prevent a laptop overheating, and gives a reader tips on how to deal with a laptop that is running hot.

QUESTION My laptop runs very hot, and I'm concerned that it could be on its way out. Is there anything I can do? Joe G

HELPROOM ANSWER Dust is the common culprit behind excessive heat, Joe. It's sometimes necessary to return the laptop to a service centre for internal cleaning, but in many cases you can resolve the problem by blowing the dust out of the vents. A can of compressed air designed for the purpose can be useful here. 

If this doesn't resolve the issue, you may find that your fan has stopped spinning. If you don't hear it whirring into action when the laptop is under load or becoming rather hot, you may need to take it to a local PC shop for repair.

A cooler can help prevent your laptop from overheating, but it won't deal with any underlying problems that are causing this heat.
