I have an Alienware m17x and I have been playing games on this primarily using steam for the last year. In that time I have never experienced any FPS problems. Last night I was playing DayZ for a while and it seemed that my charger was getting extremely warm so I stopped playing. Today I tried to play and discovered that my fps was really low. I then tested out Battlefield 3 as it is a graphically challenging game and I had never had problems with it before. It seems I am getting low fps with all of my games and I think it may have something to do with my charger not enhancing performance as it should but I'm not sure because the charger still charges the laptop fine. Any help would be greatly appreciated
