Hello,
Sorry for my english, it's not my native language.
After overheating problems, I've dismounted my laptop, cleaned the fan (it was necessary...) and changed the thermal paste.
Everything was OK, my laptop worked very well and I hadn't any overheating problem. But the fan worked always with high speed. I read on a forum that a solution might be to press hold the power button during several seconds while the battery and power cable are unplugged.
Since this operation, my laptop doens't work. It starts during several seconds, till the windows starting screen and suddenly shut down. If I try to go to the bios, it's the same thing, after a few seconds it shut down. My laptop is not hot. Thank you for your help.

Hubert
