My Razer Blade Pro Gaming Laptop from 2016 at about 2 am last night had stopped charging, after flickering from charging to not charging for about an hour and a half. When it shut off from being unplugged for a bit, I took off my headphones and heard a buzzing noise. it's much louder than normal, and it's coming from the left of the laptop, where it's charging. I'm not sure if it's a charger issue or an issue with the laptop. I had just recently bought a new charger a month or two ago. Yes, the power brick was hot when I inspected it. This morning is more of the same. Any help would be appreciated.
