Asus ZX50VW (similar to gl552) won't turn on or show the charging led

I put my laptop in my backpack, it had a 50% charge and was running perfectly fine, next thing I know it won’t turn on, and when I plug it in the charging LED doesn’t turn on. I tried a different power brick, one with the same connector and voltage, but that didn’t work. I also tried disconnecting and reconnecting the internal cmos battery, but that still didn’t help. I also tested the stock powerbrick with a multimeter and it seemed fine, but the battery use a weird connector that I couldn’t find which pin was positive and which was negative so I couldn’t test the battery. Any ideas on what I can do?
