How to reduce overheating problems on laptops by Lotfi the Expert.

Laptops suffer from overheating which you may notice after few hours of use underneath which can burn your skin or cause damage to your laptop resulting in a very complicated problem. I came up with few simple tips to reduce the likelihood of component failure due to overheating.

1) Use your notebook on a flat hard surface such as desk, table with wooden, glass or metal surfaces. if you want to use it on your bed use a large book underneath to put it on or something that is flat.

2) Do not play graphic demanding applications such as Games or Movies for long hours continuously, when you notice your fan is getting very loud and your laptop is overheating switch it off and let it cool down for about 10 minutes.

3) Never cover the ventilation holes on your laptop.

4) Carry out a full dust removal once every 6 months using an air can and also change the thermal paste on both processor and graphic chip unit once every year by a technician. as shown in my video here:

5) Set the power options to "power saver" when not using the laptop for performance mode applications such as gaming or editing.

Using a notebook cooling pad will not have such a dramatic effect to reduce temperatures as the cool air does not reach the specific components therefore do not waste money in cooling pads for laptops as you will not notice more than 2 or 3c drop.

I have an Acer Aspire 5551-2805. the problem i am having is my laptop just turn blank and only way to turn it off is to press down on the power button. Normally the laptop some time runs without any problem for hours. and just turn off suddenly. this one normally happens When i am just watching a film or just surfing the internet. But if i try to burn something, or use the usb to copy files to my system, most of the time within 5 mins it turns off. also when i play some games like sims 3, it turn off with the hour hour. but some time it goes pass an hour and turn off later on.


Your laptop is overheating, and it is shutting down to prevent it from more damage. I'm sure it is the CPU that is overheating as you mention burning, or using power hungry application will make the cpu to work harder, and increase in temp. There is a tjmax setting on the cpu that limits at a temperature when reach and shut down to prevent it from overheating. You may need to do some cleaning by blowing off the dust on the exhaust port, or even taking your computer apart and reapply your cpu/heatisink with new termal paste. Before this, check if your fan is working, and that your laptop is getting proper airflow from the bottom, you might need to get a usb cooling fan to help cool it down better in the future. I recommend not using this laptop much or long anymore as it will eventually become overheated and damaged.

i have a acer aspire 5003WLMi and my wifi is not working all of a sudden. It keeps telling me to turn the wifi switch on but i dont know where it is. please help


Hello and thank you for using Fixya.

This could be caused by two seperate issues:

1. The actual wirecard that is inside the laptop has been damaged or gone out. This can be caused by overheating or dust. Try getting a can or air, unplug the laptop and blow the dust gently to remove dust. If overheating is causing the issue, try letting the laptop cool down a few hours.

2. Driver issue - This can also be caused by a missing or deleted driver. You can visit the manufacturer's website and redownload the driver free.
