Interesting - I think this must not be a kernel problem. While trying to
do the bisection testing, I accidentally removed some needed drivers, so
I just reinstalled 13.10.

When I originally installed 13.10 (from the same USB drive), the
trackpad was definitely working, but now it is not. I think there must
be some firmware/BIOS/something setting that somehow gets reset when the
battery dies?

I don't have Win 8 anymore on this computer, so I can't test Todd's fix,
but I would be very, very interested if anyone has any ideas about how
to get Ubuntu to recognize my trackpad again!

Title:
  Trackpad not detected; Asus K55N (AMD)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Following upgrade to 13.10 my trackpad was working fine, but I had
  been having suspend issues. Apparently, last time I closed the lid on
  the laptop, it didn't suspend, as when I retrieved it today, it was
  dead. After starting the computer, the trackpad was no longer working.

  I do not think that this was following a kernel upgrade, but the page
  at https://wiki.ubuntu.com/DebuggingTouchpadDetection suggested that
  non-detection is a kernel issue. I don't really know much about kernel
  bug reporting, so forgive me if I'm doing anything wrong. :)
