I was also having trouble with my laptop. When i pressed the power button it turns on but the screen is still black. The power led is on, the batter led is blinking green, the dvd panel can be opened. So im really worried now. I tried thehard reset even though my laptop have a built in battery, i took it out and long press the powerbutton for 30 sec and plug in my charger and it automatically powered on even though i did not press the button but the screen is still black and the battery still blinking. Qhy it wont open? Please help me.
