Random Load Spikes on GPU

[creepercomputer]

Hey guys, first post here, hope you are doing great!

 

A couple days ago I got as a gift a new laptop, an Asus fx505gt (i5 9300h, 16GB RAM, GTX1650 and 500GB SSD).

The laptop is awesome, I do coding at uni and for the renders and calculations I need to do its perfect + I can play games ocasionally with ease.

The problem is this: I start the computer with only battery, everything goes fine. I now plug it to the wall, and the Intel UHD630 integrated graphics just starts spiking consstantly to 100% usage no matter what, even if all programs are closed and I'm at the desktop. CPU usage is normal in this situations, arround 2%-5%, no SSD load nor RAM, just the integrated graphics.

This also happens viceversa: plug the laptop, turn it on, everything is fine, now un-plug it, and it starts freezing the graphics the same way.

This goes away with just a restart. 

I don't know what to do, I have the latest drivers both Intel and Nvidia, tried reinstalling them, but nothing changed.

 

Any help is welcome!
