Razer Blade 15 advanced 2021

I had to take out battery from my Blade due to bloating and I was running it without it for a while without any issue.

But recently it started to overheat like crazy. On idle, literally doing nothing, it hits 100°C on CPU and 70°C on GPU. I reinstalled it, repasted it and cleaned it twice but that made no difference. It start 5 seconds after booting and stays like that no matter what but the fans has never hit max speed, only when set manually to max but that also made no difference. When trying to start Cyberpunk it just switches of completely, no blinking led or nothing. I was thinking that the vapor chamber has gone bad but, when I connected it to my Philips 346B1C monitor that has 90W power delivery thru USB-C, the laptop suddenly started to cool down and hit normal temps, around 50°C on CPU and 40°C on GPU. I had the video output on the laptop screen with the monitor connected but tried also switching to monitor only. Cyberpunk also starts now normally but in game, no matter what graphic setting are set, FPS are around 30, but the game lags and audio also lags. Synapse also displays that the power source is not enough and telling me to connect the original power supply even if its connected all the time. If I unplug it, the laptop dies so its not running of the monitor power. So maybe the power adapter is bad? I would like to hear if anyone had this problem before I try ordering new power adapter or vapor chamber to test if it helps.

Specs are:

i7-10875H

RTX 3070

RAM 16Gb

Full HD 360Hz
