i have an acer aspire 7736z-4015 laptop running windows 7. after about 15 minutes or so of usage on my laptop this evening, my laptop just shut off. i tried to turn it back on and the back light for the screen came on but the screen was blank and then it would not turn off. i had to remove the battery to shut the screen off. i reinstalled the battery but nothing will come on now. when the charger is plugged in, the light on my laptop does not come on to let you know it is charging but the light on the charger itself is lit up like normal. any help is greatly appreciated.
