I checked power saving settings and everything seems fine with them (set to performance) and I mostly use it plugged in. I'm not sure how good is CPU-Z stress test, but it was the only I had. This is after torturing this laptop with 20 fps on pubg. It reached like 92C, throttled and capped to 0.99Ghz, then I waited some time for temps to drop and ran CPU-Z stress test. And here's the result: Also what's weird HWMonitor shows that every core is at 100%, but chip only 5%? and task manager 55% utilization? The only way for clock speeds to reset now is to restart the laptop.

I get what you mean. Yeah the second is without CPU usage, so it's kind of useless (my bad), but that was the problem when I loaded some games or tests it never went over 0.99Ghz and stayed capped. I just updated Windows 10 to April update and can't replicate this whole thing anymore. I ran test's and games for more than 30 min and somehow all this time CPU didn't throttle at all so it didn't cap itself at 0.99Ghz either. Maybe it's because of lower ambient temps. I'll need to wait for warmer days to see if this is still happening.

Yeah, I ran some tests. It reached 90C and throttled. The problem is when temps drop back down to 47-50C it never goes back to at least base clock speeds and stays capped at 0.99Ghz unless I restart. This shouldn't be happening right? Though even underclocked it barely drops under 50C so maybe this is the whole problem. The laptop is pretty old and I have some thermal paste so was thinking to replace the thermal paste, but that probably won't help much with the throttling problem considering a terrible cooling of a thin and light.

Okay, so I'm not sure since when this is happening, but recently I noticed my laptop (asus K56CB) with i5-3337U @1.8Ghz that most of the time operates on boost clock speeds @2.5Ghz. After few days of not restarting the laptop (hibernate, sleep) it caps itself to 0.99Ghz and laptop slows down significantly. First time I found it capped I found someone fixing this with updating ATK package so after installing it and restarting it, clocks speeds were back to normal, but after some time not restarting the laptop it capped itself again. The laptop is always plugged in so this shouldn't be a power plan problem. Is there a way to fix this? Or is this some sort of way Windows 10 forcing you to restart, so they can run their updates? I'm new to forums, but I've been watching Linus Tech Tips for a while. I'm open to any suggestions or discussion. Thanks in advance
