[RagzXD]

Hellooooo, I have been using my "Pavilion Gaming" laptop, and I have realized one i plug in the charger port it lags unlike anything you could imagine, its unplayable. I can still use the web, but any other game is terrible too play, yes I have tried changing too better preformance, and setting as high priority. I have had this laptop for a good while, but got a full repair not even 2 weeks ago, undamged since, any help is greatly apperciated!

I'm curious -- you said you have had this for "a good while" (I'm presuming -- years) and you also had this "full repair" recently -- so is this problem ONLY since this recent repair?

IF so, they messed up something during that "repair".
