I looked into this and realized it was about firmware, which apparently
can't be updated without hooking up to Windows. I don't think it's worth it
because like I said it worked with the firmware it's got for quite some
time.

I'm out of ideas. Can you guys think of anything?  I'm thinking I will need
to just rebuild my machine with a fresh install of the lastest Ubuntu and
see if that helps.  I've been getting this "system software problem
detected" popup a lot. Maybe that has something to do with it.
