I have a MSI GF66 12UEK model.
It's probably been about 2 weeks now after the issue started happening where unknowingly my charger starts to constantly connect and disconnect over and over.
When im not running any games the charger works perfectly fine, but when i start trying to run certain games, the charger stars to connect and disconnect itself consistently which makes my frame drop constantly.
But sometimes those games would run normally without any charging issues.
Ive tried resetting the EC and reinstalling the battery device and the problem still persist.
I have only manage to run certain games with no issue, and sometimes the game i have issue with after awhile randomly and is unsure how to fix it, common solution that i should get a new charger.
