Unfortunately i am back on 13.04 and installing with the patched driver
still results in freezes when on battery. I will try and rebuild this
evening.

Title:
  Random system freeze in 13.04

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I am having a problems after upgrading to 13.04. This problem was not
  apparent in 12.10.

  My system now freezes randomly. When this happens i cannot input (no
  mouse, no keyboard) or output (if music is playing it starts to skip)
  anything from the machine. The only option left when this happens is
  to hard reboot by holding down the power button. The freeze appears to
  happen randomly and could occur after 3 minutes of use or after 10
  hours. It has even occured during the shutdown process.  I have no
  sense what, if anything causes the freeze.

  I have seen that i am meant to upgrade my BIOS before posting bugs,
  and while my BIOS is out of date, i see that my BIOS update now
  includes a UEFI update which i am worried will break my system. As
  such before fiddling with the BIOS i thought i'd see if this was a
  kernel issue or a bug.

  I am running 64bit Ubuntu 13.04, dual booting windows 7, on a Lenovo
  Thinkpad x131e.
