FPS drop when plugged in and charging

[skibs]

 while gaming, the FPS drops whenever I am charging this laptop. Problem still persists when battery is removed and laptop is only being powered by AC adapter. When unplugged and powered by battery, FPS in games stays constant and perform smooth.

I have tested CPU and GPU temps, and none of them are hitting above 75 degrees so i doubt it could be caused by thermal throttling or overheating. 

All drivers and BIOS are updated. I have checked the power options, and it still happens when both power settings for on battery and charging are the same.

I also bought a 90w charger to see if it was caused by power sortage (it worked in other forum) but nothing changed. 

I have already received a replacement 65W adapter from HP, but this issue still occurs.

After contacting tech support, a lady on the phone told me that laptops' performance decrease when charging, and recommends me to use the laptop on battery for better performance? What??

After doing some searching on Google, there seems to be a few similar individual cases being brought up on various forums. Some of them were solved via a BIOS update, a few commented that it could be a problem with the AC adapter.(already tried all of it) 

Also The fan no longer works the way it was because it never changedsits speed no matter what temp.

I reinstalled windows 2 times and update them nothing changed,

Pls suggest something that you have  not already because non of the forum worked for me.
