It is very common that laptop owners experience their laptop overheating. Some signs that this is the case are when your laptop suddenly shuts down after operating it for a certain amount of time and its casing become increasingly hot as you operate it. Most of the time, the cause is dust accumulating to the cooling fans and the heatsink which in turn causes the processor to overheat and the bios shutting down the computer in order to protect the CPU.

If you can hear the laptop's fan spinning it is a good sign that it is working and that a replacement would not be a neccessity (something that would require dissasembling the laptop and replacing it). A complex and risky procedure to try without the help of an expert (Computer Repair London) .

However, before resorting to bringing to us you can try the following tips:

1) Unblock the air flow by blowing into the laptops exhaust  (from the bottom and side) with a compressed air can .

2) Keep the laptop on a flat and hard surface. When the laptop is placed on an uneven surface such as a pillow or blanket the flow of air is disrupted and the laptop overheats. You can avoid that by placing it on a tray or a special laptop holder or stand.

3) Purchase a laptop cooler which either blows cool air upwards or merely absorbs heat.
