12.04.3 ships with the 3.8 kernel whereas 12.03.2 ships with the 3.5
kernel.  Would it be possible for you to test the latest 3.8 upstream
kernel to see if the issue exists there as well:

Title:
  [HP Pavilion 15 Sleekbook] wireless hotkey function loss on 12.04.3
  but works on 12.04.2

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  CID 201209-11789

  Hardware: HP Pavilion 15 Sleekbook
  image: 12.04.3

  Step to reproduce the bug:
  1. boot into the system
  2. connect to wireless AP (if any) via the indicator on Desktop (upper-right hand side)
  3. if connected, make sure we could surf on internet
  4. press the wireless hotkey, in this case, it is F12

  Expected result:
  1. the wireless will lose connection
  2. no AP on the scanning list of the wireless desktop indicator
  3. wireless LED will change color (from white to orange)

  Actual result:
  nothing happened

  More information may help:
  1. "rfkill list" shows the soft block was still "no" after the wireless hotkey is pressed
  2. "sudo showkey -k" has no response when the wireless hotkey is pressed
  3. 12.04.2 will not have this bug on the same machine
