Razer blade advanced 2022 turning off ehen is not on original charger

I have a Razer Blade Advanced 2022 with an RTX 3080 Ti and an i7 12800 HX. Besides the temperature and bottleneck issues it's experiencing, I've always used it outdoors with a Power Deliver charger with 100W, but in a few weeks ago the notebook It started shutting down even when the battery was charged, and it doesn't turn off when I plug it into the 100W charger.It only turns on when I plug it into the original power source. If anyone knows how to solve this and the temperature problem, I would be eternally grateful.
