Not sure how to fix this problem. My netbook completely crashed tonight. It goes to the black screen telling me it shut down incorrectly (because it froze, I had to press and hold the button until it finally turned off and when I went to turn it back on, it wont boot up.
I am on a different machine right now so I can't be too detail. With this problem in the past , I turned it back on and got the black screen.
There are about two function keys (FN)+ that can bring it up into a state of checking your system drive. When through it should boot up. It can take some minutes for the check so be patient. It will do this check to see why you had the freeze and initiate possible updates.
I sure hope this will help you, it me.
If you can't find the right key just press them and wait you will come to the right one. It won't do anything else until you hit the right key anyway. I can't remember what that key says.
