BondCreat, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [HP ProBook 4540s] brightness control problems

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I bought a laptop in December 2012, immediately tried to put Ubuntu
  12.10, got broken wi-fi and non-working graphics acceleration. Updated
  kernel to version 3.6, with graphic acceleration was all right, even
  partially earned wi-fi. After some time wi-fi hang, helped only
  restart the network subsystem.

  Updated kernel to 3.7, with the wi-fi was all became normal, but
  stopped working brightness control with the Fn keys. Progress bar
  indicates that the brightness changes, but in fact nothing happens.

  Tried the new distribution 13.04, on 3.8 kernels, 3.9, 3.10, nothing
  changes. Upon adjustment has broken in 3.7 kernel. It turns out that
  this is a regression.

  Hardware Configuration:
  Intel Core I5 3210M
