So I have had this laptop for coming up on 3 years now, so there's bound to be problems popping up. The issue I'm having is that the charger wont stay connected. Now this should be easy, just get a new charger. But I've also been having issues with my battery and was wondering is there anyway to check to see if this is a port issue, a charger issue, or a battery issue. The main reason I've noticed it is because the screen dims for a second or so every time the charger reconnects. So is there any way to see what the issue is without buying a new charger.
