Surface Pro 4 won't turn on at all after battery replacement
Text:
Hey! So I followed the guide here on iFixit to replace my battery. Unfortunately now my Surface Pro 4 won’t turn on at all (unplugged or plugged in). Nothing happens, not even the fan goes on.
I can’t really figure out what the problem might be. Maybe someone can give me a clue where to look next or what it might be?
A few more notes:
* When I tore off the screen I broke one of the three antennas at the top, but I would guess this wouldn’t cause this problem.
* When I first tried to turn it on, I forgot to connect the fan back to the mainboard. I fixed that very shortly after.
* After it didn’t work the first time, I removed the battery again and put it back in, but that didn’t help either.
I hope that is enough information!
