Oh yeah, that one's good.

So it's been at least one year since my Lenovo Y520 (bought about 18months ago) has been throttling its i5 at 800Mhz for no reason.
The thing was so fucking slow, you can't even imagine.

A few months back I found why: the fucking processor raised a PROCHOT flag constantly, even though it never exceeded 60°C.

So now, everytime I boot my computer, I have to run a fucking script to reset this fucking flag. Seriously Lenovo, what the fuck?
