A while ago there was an older computer game that my graphics driver wasn't working with. I downgraded the driver to play the game. Ever since that day, every time I unplug my laptop the screen goes almost black. The power cord is fine, the power options are fine. I reinstalled the up to date graphics driver from Intel and that didn't fix it... I don't know what else to try?
In order for me to provide more information and help you with your issue, can you please post your dxdiag report here?
