========================
Detailed description：Around October 17-19, my laptop(BIOS 308, the latest offered by MyASUS) performance suddenly decreased. For example, playing videos games my FPS would be 60 normally, but now it is 9-30. Overall, there are stuttering and lagging when playing video games. My internet is working fine. Streaming videos, doing multiple tasks, or downloading, there are noticeable lag. MyASUS(V2.2.44.0) checkup shows there may be an issue with the fan. I've went to Nvidia Control Panel and set it to High-Performance Nvidia Processor, Power Option and set to High Performance and still nothing. Using Turbo mode, the fans are somewhat quiet and CPU/GPU fan kicks up to 2800-2900 RPM. Normally, using Turbo mode, the laptop emits a very loud noise and CPU/GPU fan kicks well over 5000-5500 RMP. So something is wrong here. I've also installed ASUS System Control Interface V2( V2.2.30.0) and reinstall MyASUS and the problem still persist. I've also resetted my laptop twice and it fixed nothing. I've checked Task Manager and Armoury Crate(V3.1.6.0), CPU/GPU temperatures seems fine. I'm not tech savy and not sure what is going on. Could it be CPU/GPU fan? Or motherboard? If you need more information to help a guy out, please ask.
Edit: I also should mention when I do Full Scan on Window Virus Security, it usually take 15-20 minutes and utilization of CPU is 98-99%. Now, it takes slighty longer and utilization of CPU is around 33%. I don't know if that info will help. I've also never underclocked or overlocked my CPU because I don't know how to do that.
Edit 2: I've emailed ASUS about the issue. It will take 48 hours for them to get back. I will update as soon as ASUS respond.
Thank you

Did you set battery saver to turn on automatically at 30%?

Nope, Battery Saver is turned off and in advanced power settings minimum processor state on battery also set to 100%.

I just noticed that after updating BIOS 308 to 309, my led light for charging doesn't turn on after shutting down and closing the laptop. Usually, the led light turns amber to notify it is charging then becomes white to show it is full. Led power lights only work when the laptop is turned on. Either that or my laptop is not charging when it is shut off. Anyone have this problem or know the solution?

Edit 1: Ok. So when turning my laptop off, it does charge. The problem is the charging LED light does not turn on(amber) to indicate it is charging or white that it is full. But turning on the laptop the LED charging lights works as intended.
