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.
