Bug description:
  [Impact]

   * There are many Bluetooth devices with battery information inside.
  When they are treated as system battery, it will make the system
  poweroff/suspend/hibernate when some Bluetooth device has critical low
  battery. It is a very annoying behavior for the users. Originally,
  there is no such Bluetooth battery information until Ubuntu 12.04
  brings linux-quantal-lts and linux-raring-lts, so those linux kernels
  also bring this issue.

  [Test Case]

   * Pair some Bluetooth devices, such as Apple Wireless Mouse or Apple Wireless Keyboard.
   * Click the power indicator and you can find Apple Wireless Mouse is listed as system battery, and there is no Apple Wireless Keyboard. If you open gnome-power-statistics, you can find the 'Supply' field of Apple Wireless Mouse is 'Yes' but it should not be.

  [Regression Potential]

   * There is no obvious regression as I know.

  [Other Info]

   * Most patches are from upstream, modified to fix the conflicts, and made by the same developer (i.e. fourdollars).
   * We need another patch from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d0a934b764c67b4bf626f5b7cf725a6e3066afd2 to make Apple Wireless Keyboard showing.

  [Original Bug Description]

  This is a weird one... the system is an HP Pavilion 23 All In One and
  is powered by a large power supply brick.

  I currently have an Apple Magic Mouse connected via Bluetooth.  As
  soon as the mouse is connected, the Battery indicator shows up and
  clicking on that shows that the system is reading my mouse as a
  battery!

  See the attached screen shot for what I see in the Power status.

  Looking at hcitool:
  ubuntu at 201206-11396:~$ hcitool dev
  Devices:
   hci0	9C:B7:0D:80:71:DB

  To make matters even more weird, I actually observed the battery
  indicator go from full to "Critically Low" and the system suspended
  itself.  Keep in mind, again, that this system has NO battery, it's
  reading my bluetooth mouse as a battery device.

  I disconnected the magic mouse and the battery indicator went to Empty
  Red outline and status showed Battery Disconnected.
