I took my battery out of my Sony vaoi laptop and put it back in. I then turned it on and everything was fine! It said it had to restart or something to finish repairing a disk or something and then a sentence came on the screen saying it might take over an hour! About 2 hours passed and the message was still there! I turned it of and turned it back on again! It turns on and says Sony Vaoi and then it goes to a black screen and stays like that! But it is turned on! I've tried everything like leaving it that way over night and taking the battery out for a good few hours but this still keeps happening! Help please 🙁
