Restarted my laptop after all-night torrenting, and when the exhaust fan felt unusually warm, I notice the setting is gone, my CPU is running on max-speed no matter what profile I choose (even setting the CPU to always low in BIOS don't work). I've tried resetting the power profiles, and still nothing happened. Maybe an in-place upgrade would solve this, but is there someway to restore it without spending few hours waiting the process? Or did the failure of BIOS option for forcing to low power (which previously work just fine, even on Linux distro which doesn't support power throttling) is a sign of some hardware problem?
EDIT : I check CPU-Z and it turns out my CPU throttling is still working normally. Even the reset doesn't change the state setting (I set it to always use the lowest on power saver, and maximum at 80% on balanced), so the setting somehow doesn't appear, and it's not affected by setting reset too. The task manager still report as if my CPU is working on maximum frequency though.
