My MSI GE72 6QF was running fine and while I was working suddenly powered off and doesn't power on again. Tried all possible methods I could think of. Removed the battery and held power button and retried. Removed cos battery and tried but no sign of life. No signs of burn or weird smells were there. And it's in a very clean condition. There is no lights coming up when the power adapter is connected. Before it shut down around 10 minutes before I noticed battery was also full. And usually battery lasts at least an hour so can't be that. Out of warranty so in a fix.
