i was wondering if this is a bad fuse or bad battery, because i just replaced the battery. i get the message warranty service. and when i go to device monitor, and this what it looks like. The board works fine when the battery is unplugged, as fine i mean when its disconnected from the mod and just plugged in through the usb. i would just check the fuse but, i cant get to it because its on a thick plastic mounting piece, i don't want to risk breaking the board to get it off.
