Laptop switching off due to overheating, what can I do?

By March 11, 2013Uncategorized

If your laptop is getting hot and switching off it may be caused by dust collecting in the cooling system. After prolonged use every laptop require cleaning of the cooling system.The largest amount of dust and dirt is deposited inside of the heat sink and fan.If your laptop hasn’t been cleaned for long time the air ducts can get completely clogged with dust, pet hair, etc.

Lack of air circulation causes a rapid rise in temperature inside the case and a number of problems with the operation of the laptop and may cause permanent damage.


The most common symptoms of laptop overheating:

  • laptop casing getting very hot
  • increased noise due to fan working at high speed
  • laptop crashes and freezes
  • noticeable decrease in performance
  • unexpected shutdowns

You may try to clean the laptop yourself if you feel confident enough to do it, however we do not recommend to do this as you may cause permanent damage to the laptop. You should also avoid using compressed air to clean the dust. If there is a small dust deposit it may do the trick but in case there is a large dust deposit using compressed air can cause dust to block the fan blades which will result in permanent damage to the processor and graphics card.


The only legitimate solution for heavily dusted laptop is to physically open the case, clean the cooling system and replace the conductive thermal paste between the heat sink and processor as well as graphics card.


In order to perform a thorough cleaning and servicing your laptop should be booked for the repair with the professional. You can email us or call 020 3086 7882 to arrange the repair.
