Hello! I have a ROG GL753V for over a year. A few days ago I noticed that whenever it's on, the fan would not slow down, even though it wasn't overheating. But as I don't use it daily, it didn't bother me much. Last time I used it on battery a couple of days ago and it was just fine. Yesterday when charging the battery icon was constantly blinking and now it won't start unless plugged in. When I do start it in charge mode, the battery icon shows it's at 0% constantly and won't go up.
To my knowledge batteries die gradually and not instantly like that. So is there something I can do?
