I have a gaming laptop (acer aspire timelineX). I'm having trouble when I play any graphically intense games(guildwars 2). I set the settings all the way to low and after a short while I will get the warning sound that the battery cable is unplugged and the screen will dim to low for a few seconds, this will continue on and off for a few minutes and eventually subside. After playing for a while the performance will start to drop.
I'm guessing the machine isn't getting enough power, is there a way to feed it more or is there another problem/solution going on here?
