  Unable to toggle Touchpad by keyboard shortcut

Status in linux package in Ubuntu:

Bug description:
  Pressing Fn+F5 button should toggle the onboard touchpad. This seems not to 
work and might be related to the following bug:

  After pressing Fn+F5 shows the following:
  $ dmesg
  [  248.412826] atkbd serio0: Unknown key pressed (translated set 2, code 0xf8 
on isa0060/serio0).
  [  248.412833] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it 
  [  250.261108] atkbd serio0: Unknown key released (translated set 2, code 
0xf8 on isa0060/serio0).
  [  250.261110] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it 

  I've added the mentioned kernel parameters as described in 
  https://wiki.ubuntu.com/DebuggingACPI (adding acpi=off)
  but the problem still exists. 

  Touchpad also has a little dot in the upper left side which I assume
  also is for toggling on/off the touchpad. This is also unresponsive.

  How reproducible:

  Steps to Reproduce:
  Press Fn+F5

  Actual results:
  Touchpad is not working

  Expected results:
  Touchpad should toggle on/off, making it able to use the touchpad.

  Extra info:
  Bios is up to date.
