My Razer Blade 15 keeps shutting down. It dims like it is fixing to fall asleep and then instead of falling asleep is shuts down completely. Is also does this while I am in the middle of using it. The laptop is plugged in, so it's not that. Also, this battery in it isn't even a year old yet. I had to replace the battery last year because it wouldn't hold a charge. Is anyone else having this problem too?
