Couple days ago the screen will freeze after I move the laptop a little from the desktop. We thought maybe the hard drive went bad so we changed the hard drive yesterday. While I was doing all the update today it did it again and again. I left the computer sitting there by itself and it won't turn back on later on. I pressed the power button and the fan will turn on the all three light from the left of the keyboard (hard drive, battery and wifi) will flash once together then battery light will keeps on flashing. I have tried to unplug AC power and let battery runs alone or unplug battery let AC power runs alone but none of them work. Please Help !! thanks
