[Bug 1153488] [NEW] Treats bluetooth input device batteries as batteries

Fri Oct 11 08:12:06 UTC 2013

You have been subscribed to a public bug by Shih-Yuan Lee (fourdollars):

[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:

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.
