Doug Schaapveld, as per
http://support.lenovo.com/en_US/downloads/default.page? an update is
available for your BIOS (1.43). If you update to this, does it change
anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  [Lenovo ThinkPad T520 4240] won't boot with 3.5.0-27

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After updating to kernel linux-image-3.5.0-27-generic a week or two
  ago, my T520 4940-49U won't boot.  After 1-2 seconds, the screen goes
  blank (dark - backlight off) and the laptop stops responding.  Alt-F2,
  etc does not cause any change.  Alt-SysRq-B will reboot, but nothing
  else has any effect.  The hard disk light is not on/blinking.
  Removing the "quiet splash $vt_handoff" options from the grub boot
  options does NOT help; also adding "nofb" does NOT help; also adding
  "init=/bin/bash" does NOT help.

  Booting recovery mode for 3.5.0-27 DOES work.  Booting 3.5.0-26 in
  standard (non-recovery mode) DOES work.

  I'm unable to capture any output from a failed boot, so not sure how
  to troubleshoot further.

  Attached data was captured while running 3.5.0-26 (NOT the problem
  kernel).
