Dave Peck, as per
http://www.sony.co.uk/support/en/product/SVE1712C5E/updates an update is
available for your BIOS (R0170D6). 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:
  [Sony VAIO SVE1712C5E] Backlight brightness controls not working in
  12.10

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have recently updated from 12.04 LTS to 12.10 to enable better
  support for UEFI booting on my machine.

  Now that I have updated to 12.10 the brightness controls no longer
  work. They were working fine in Version 12.04 LTS. I have been
  debugging this problem with a very helpful person (Toz) on the Ubuntu
  Forums and it would be worth taking a look at this thread to see
  progress to date http://ubuntuforums.org/showthread.php?t=2092897

  As suggested I have created a bug report with "ubuntu-bug linux" in
  terminal.

  I am happy to provide any additional information they may help resolve
  this problem.

  Regards,  Dave.
