So, suddenly one day, while I was plugging into my wall, it showed no response. I have checked the battery is fine its giving more than 25v, and the wall supply is also fine its that when I press the power button, nothing happens. When I connect the battery no response, and it's just completely silent. I have a multimeter. I can't lose this board now, so can someone help me troubleshoot this? I really don't know what happened there; there isn't a single overheating or burn mark, everything is fresh, that's why it's hard to understand what really happened. Oh, and there is no visible fuse, and the circuit breaker is also fine.
