Did you try a battery reset? Remove the battery and then reinstall it. Doubt that is the issue but is possible. Good luck!
Hello, I am new to the cnet forums.
I have a Dell Inspiron 6400 laptop with Windows XP and I have had it for about three years. I left it on with Google Chrome and Notepad open overnight and when I got back from school, it was still on but the screen was black (and I know its not hibernating or on standby). I have tried everything to get it back on. This has happened before and I just turned it off. When I turned it back on, a screen saying something along the lines of "drive unidentifiable." So I opened and closed the disk drive, it worked again. Is there any diagnosis or any idea on what to do? If so, would prefer to keep the computer on because I had an important document open in Notepad I would like to save.
