hi guys. So, for Christmas I got a Lenovo G505s laptop. It's great for gaming on medium to high settings, but here's my problem.. it's only good for gaming if it's not charging. I'll get a steady 40-60fps until I plug the charger in and switch it on, then, the fps drop to 7. So I did and a test and left the charging, but took out the battery. This resulted in the normal 50fps or so, so is it a faulty battery? I did tamper around with the power options, but i think i set them all back to normal.
I really need your help here guys, please.
