my screen on my aw 17xr3 doesn't light up.but i can hear the pc start up like normal...if i keep turning the LT on and off sometimes the back light turns on and it will work but it hasn't got that far in a while. Also if i remove the 460m vid card it will light up..but it just gives me the beeps telling me no vid card. I could of sworn there is a way to switch from the gpu to the on board video but it was disabled with the A9 bios. i have read that the current one allows it to be done but i don't know how to do a blind flash of the bios. please help i have posted on the AW site and no answers from any one. its also out of warranty.
