    The article is very helpful, even though you don't have any problem on the computer.

    Had the same problem. If you do a forced shut down from the black screen then it will start normally the next time. The fix was to disable fast boot. That fixed it. My toshiba never could come back from hibernation.

    What about when it's not there now? I've tried several times. I can't get it to show up. I'm in safe mode because regular startup only gives me. The black screen. That's what I'm trying to fix. There has to be a way to get it to work.

      @Megan: Your system has a different problem (black screen) than the article describes (Fast Startup). In your case you have to find out which program or service causes the black screen. Try to restore your computer to a previous working state or undo the latest changes you applied on your system. (e.g. uninstall the last program or driver you installed)
      p.s. If Fast Startup option is unavailable, apply the steps on Part 2 on the current article (Enable Hibernation).
