M18 R1 performance/battery issue?

[Popcan]

Just wanted to get opinions on what I should do. Warranty is up in April.

 

Started off a few days ago, turned laptop on started a game and I was stuck at 45w on the gpu. Normally it runs at the 175w mark. CPU due to undervolt and whatnot only hits about 100w max.

 

I have 2 330w adapters same results. 
Noticed battery won’t charge above 9% 6555mv. Battery is also in excellent health I ran the whole diagnostics deal in the bios.

I also got 4 red flashes followed by 1 solid blue. While doing this

 

unplugged the battery and waited for a bit.

That still didn’t fix it. I left it charging for about a half an hour and all of the sudden it jumped from 9% to 100% with 76000ish mv.

 

so far it is working normally but the laptop often hangs at 93% charge even while not doing anything. Has always said charging in windows.

 

any suggestions? Idk if Dell would even do anything.

 

  Cheers!
