My Blade V8 Pro took a hard knock on it's side and continued to function for another 30 minutes. After that it restarted, said the battery was at 100% (I predict it should have been at 50 to 70%), then proceeded to shut down and say that it was due to low power. It has since held to that belief despite charging with the supplied charger. I opened it up and all appears intact. I have been able to boot it up, then immediately plug it in, to get it going for about 1 to 5 minutes before it decides that it needs to shut down due to overheating. Any ideas on what's wrong? The screen is 100% fine thanks to the screen protector.
