Why wont my screen turn on? SolvedMy battery is fully charged. When i press the power button, i hear the "on" sound; however, my screen stays black!
"On start up I get the tone then immediate shut off"에 답변I JUST HAD THE SAME PROBLEM!!! I was trying to fix my friends mac and it fixed its self after i realized there was a disk in it. so i pressed f12 during start-up and it works now!!
