So, again as originally recommended by Usasma, get down to the computer shop and buy a tube of thermal paste. It looks like, from your report, that you are heading in the right direction. The paste is not cheap and, if you read my original post on the i3, I would not guarantee a 100% result. Worth a try, though?
Okay! so i bought some thermal paste and applied it to the gpu and processor and sealed the laptop...
In initial testing, for abt 10 mins, i played a 720p video, during which the temp spiked about 3-4 times and at the fourth time, it didnt cool down and reached 107 and the laptop shut down...
However i was able to achieve d minimum temp of 50 which a couple days ago was impossible!
So it didnt xactly solve the problem, bt made it a lill bttr...
I'll watch for a couple of days.. if it aggravates, den i will give it in lenovo for diagnostics and repairing...
P.S.
A guy i met for this thermal paste said that there can be various reasons for the laptop to shut down, like the fan running at low rpm or the graphics card malfunctioning... He said graphics card malfunctioning is rare so i must check the fan speed and rpm..
However he said that for checking that, there are no softwares available and that i must keep the laptop with him so that he will check it..
I'm nt sure i believe him and/or trust him..
Is there any ways to check the rpm and speed of the fan using any software?
If so any links for such software would b appreciated!!
