Hello all,
Since I bought this laptop I have a problem with overheating. The temperature isconstant 70-90 degrees. Laptop works when I hold him in the air, but when you put it on the surface immediately reaches 100 degrees and turns off.

* I made a bios Updates
* I cleaned it from dust
* I put the thermal paste
* The processor is limited to 70% but can not work on it, I'm involved in music production , and I'm live deejay so that's why i cant send it on warranty, i have warranty 2 more months and if it's needed i will sent it but first i want to check out if you can help me somehow.

Another problem I have is with the screen. He has a idle 2 cm, and when it run Forward - backward , you hear a strange sound in left holder , like it's broken , Is it possible that the holder of the screen is broken, can I fasten it?

 I am sorry if i put it in wrong board , i am new here.

Thank you
