It would also be good to know if this has already been fixed in the latest upstream kernel.  Can you test the v3.11 final kernel:

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
