My microsoft surface laptop 3 was simply switched off while working without warning and can no longer be switched on. Battery done
I do not know the Surface Lapton, but would first tap on a completely empty battery. A defective power supply is also conceivable. In the worst case, the mainboard is over, then the repair and replacement part is more expensive than a new notebook.
If you still have a guarantee, send it in. If not, have it checked by a PC screwdriver near you if you can't do it yourself.
Thank you for the answer, it was apparently due to the completely empty battery, because everything works again after 1 hour
