Dang. Why do you ask ME all the hard questions?

Hokie. It looks like HP puts a HP Reovery Manager application on your harddrive. When you open that, one of the options should be Factory Reset. So, if all else fails you can do that, nuke all the work you’ve done to this point, and start over without any junk installed.
If that bad boy can’t print or open your external drive after you’ve done that, it’s not a laptop, it’s a doorstop.
And you can tell it I said so.
