My predator17 froze so I tried to force shut down but it wouldn't do it. So I unplugged power and let the battery run down. This morning I pressed a paperclip in the battery reset button for 5 seconds and then plugged the power in and tried to turn it on. The laptop started but with a black screen. So i force shut it down and that turned it off. So after research I unplugged it and held the battery reset again, this time I held the power button in as well for 30 seconds to rid the laptop of any residual power. Then plugged it back in and tried to turn it on again with the same result: laptop turns on but with black screen. Any suggestions?
