Surface Laptop Studio doesn't turn on anymore
So I have a massive problem...
two days ago, i was just playing a game on it, then it suddenly turned off. I realized, that it wasn't charging (the light on the connector was off), even tho its plugged in. I thought it just turned off because the battery was empty, this happend a couple times already, and for some reason, the laptop doesnt warn me when the battery is down when im gaming.
So I unplugged everything, and plugged it back in, then it worked again and the light is on.
Then, the windows logo popped up, but didappeard after a short time again, and nothing happened.
And since then, my laptop is in this stage. No matter what i do, it's just this:
(And yes, i have tried pressing the power button for 20-30 seconds many times, also tried various other combinations like windows, cntrl, shift, B or F4+Powerbutton, etc. Nothing worked...)
