I am here today with a problem which I have been trying to solve for a few months by myself and now I ended up with no solution whatsoever so I need some help.
At first I have this very laptop: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en... which is new.
From the first days I noticed that it has a very high CPU temperatures, and that is 55-60C on idle Windows 7, and it is 80-85C while playing some game or even watching high-definition movie on VLC player. Yes, those numbers are high and what I did from the start: I installed HP Coolsence software which does nothing, and then I reapplied thermal paste which gave a few degree difference, it is 75-80C on game, but still, maximum temperature is 85C.
Those temperatures would not be such a big issue, at least they would not burn CPU out of the laptop case or damage computer in any other overheating way, but there is a very strange thing which I called CPU throttling, at least it looks like it.
Then I go from idle to some game on this HP computer, after some time (2mins) the core i3 itself goes clocked down from ~2300MHz to 768.1MHz, and the CPU temperatures only starts to go high at that time, it throttles at only 60-70C.
Then I discovered this, I tried some software to stop throttling, specifically ThrottleStop which aloows one to set CPU multiplier manually. So I set it to 23 and it keeps at that for a while, but after some play time, it seems like ThrottleStop and motherboard or whenever does throttle is at fight and clock jumps and goes down from 800MHz to 2300Mhz all the time. It is not stuck at 786MHz but still the CPU power is very poor as more than a half a time it work on lowest clock.
