Some models break down like that and the news is grim. You can't trust CPU temps but always know to do the work. I'm finding more folk that won't do the work (cleaning, heatsink compound replacement) for many reasons. If you don't do this sort of work, then have it done. There are folk that want assurance that it will fix it. But that would require I see the laptop ahead of time to check out the model's history on the web, prior run ins and such.

My laptop won't boot anymore. If I push the power button, the LED turns on and the fan starts spinning normally. After 2-3 seconds, the fan starts spinning very fast, and 2-3 seconds later, the laptop turns off itself. I think it's the motherboards temperature sensor that gives a too high reading, so the laptop tries to lower it by spinning the fan at full speed, but then it shuts down. Sometimes, the laptop shuts down before the bios screen shows up (Press F2 to enter bios), but sometimes it reaches the bios screen and then it shuts down.
Very sometimes, the laptop does boot fine, but the fan doesn't spin at all. When I open speccy, it says that the motherboard is 5 degrees Celsius (41 degrees Fahrenheit). I think that's the reason the fan doesn't spin then. My CPU temps seem normal, but after some activity, the temperature gets high because the fan isn't spinning.
The bios doesn't show any temperatures readings, and most of the time, I can't even get into the bios. What do you think it is? And, can I repair it?
