This affects me as well. ThinkPad S431, using UEFI (not legacy boot). I
don't need to put the machine in suspend though. I can just shut down
Ubuntu, and the computer turns off then turns back on again. So I reboot
into the BIOS and hit the power button to turn the laptop off. Once
again it boots up, I go into the BIOS, hit power, and then it stays off.
I think this is related to UEFI.

Title:
  Thinkpad T430u reboots twice after suspend then shutdown

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  If I power on, use my computer without closing the lid or otherwise
  suspending it, it shuts down fine.

  However if I suspend it at any point while using it, then shut down,
  after it completely powers off it turns on again, exactly twice.  The
  first time it turns on I hold the power button before Ubuntu boots up
  to turn it off, then it will power on exactly one more time, and I'll
  hold the power button again to turn it off the second time, at which
  point it stays off.

  This isn't a recent change; I've noticed this behavior ever since
  installing 12.04.

  In case it's relevant, I'm using BIOS instead of UEFI, and I am dual
  booting with Windows 7.
