Not a diagnostic, more of a simple check - - make sure all the air vents on the laptop (usually situated underneath & on the sides) are clear of fluff & dust build-up.

Also, avoid using it on your lap unless it's sitting on a hard, flat surface such as a meal tray. When placed directly on your lap it can overheat because your clothing and the uneven surface are blocking one or more of the air vents.

 

Thanks for the advice but its not that simple. Air vents have been clean and this problem still exists even on a flat surfice. The only wait i can stustain use over a period of time with several applications running at the same time is by proping up the back end and forcing more air underneith via fan

 

Hello and Welcome to TSF.

Try using compressed air to blow out the dust etc... from the fan.

You can find a can at walmart...example.

They do sell dual fan units that laptops sit on to provide extra cooling.
