Razer Blade 15 Advanced won't stay plugged in when game running

As many others have experienced by the looks of other posts on the forums my Blade 15 Advanced recently stopped consistently charging when a game is focused. Works fine normally but as soon as I run a game and have it focused it constantly goes back and forth between plugged-in and not. This obviously affects game performance and also eventually the battery drains to 0 even when plugged-in.
