Tip & How-To about Computers & Internet

Laptop over heating

To reduce the effect of the heat in a laptop, a fan and heat exchanging grill are attached to the CPU. The fan pulls air into the laptop from the bottom and blows it out the back. This produces a vacuum under the laptop and draws dust into the laptop which can clog the fins of the heat exchanger. After a while, usually just as the warranty runs out, it will start shutting down, locking up or any number of other things that are not good. A really good cleaning of the fan and fins are required.

TIP: Blow the dust from the fan and fins. To reduce the dust collection, Tape a coffee filter over the fan opening on bottom of the laptop. This will reduce the dust and can be easily changed when needed, and it's cheap.

My ibm thick pad laptop suddenlly off every time i on it what might be the problem


When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.If you are notusing your laptop on a flat surface, it may be obstructing the cooling vents onthe bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.A laptop fan assistedcooling pad may solve your problem

i have a sony vaio laptop.. after using it for a several minutes, my laptop will shutdown without any warning.. I check the the cpu fan but it works fine, please help me..


Did you pull the fan out to see if you have dust plugging the heat exchanger? over time the copper part the transers the heat to the fan area plugs up with dust and will prevent the air from moving and it will over heat causing the processor to kill everything in an attempt for self preservation.

More than likely just a dusty heat exchanger. Or else you have a video card getting hot too.
