Hi, I have and old laptop which is Dell precision m6600, having a gpu Quadro 3000m. My power cable (250v) is not working and then I saw an old (125v) power cable, plug it in and it seems fine but I notice it's not generating enough power because it's charging my laptop very slow. Does this affect also the gpu performance? I know that this gpu is not for gaming but when i re install the drivers and play dota 2, my fps reach at a constant 150 fps. But when I turn off my laptop and open it again, the fps reach only 40. I don't know what seems to be the problem.
