OK, none of those backdoor passwords worked. There's some guy online who says he found a way to override any password, (I guess from a Fujitsu laptop). He sounds like the type of computer geek that loves a real challenge. Doesn't sound like a bad-guy. '

I downloaded a PY file, (Python) script file... but the computer was unable to open it. I did a little Googling and redd that if I can't open that kind of file, I may have registry problems. Does any of this ring a bell with you.
I realize we're at the end of the line.

Thanks for everything you've done. I only wish I had YOUR knowledge!
