upower showing keyboard at 0% charge

[Kevin Krafthefer]

This bug is new upon upgrading to 13.10; bug did not exist on 13.04, 12.10 or 12.04.

I'm using an apple wireless keyboard. I have replaced the batteries and confirmed they are fully charged with voltmeter.

Keyboard is working fine but indicator says it's 0% and is red indicating some problem. Also upower says "keyboard not present"; bluetooth shows keyboards.

I have 13.04 and have power indicator reporting 0% per Apple Wireless Keyboard.
Upower daemon said "no valid voltage value found for device".
Is there any chance to ask upower to ignore keyboard or detect voltage correctly?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[X-Stranger (xstranger)]

Looks like nobody is interested, so I did a dirty hack to make upower ignoring Apple Wireless Keyboard. The patch is attached.

Posting the pre-compiled package for patch testing and for everybody else interested.

Thank you for your bug report, could you report the issue upstream to https://bugs.freedesktop.org/enter_bug.cgi?product=upower ?

[Jean-Pierre Rupp (xenog)]

I have added information to the upstream package, and modified the patch slightly in my system to ignore Logitech K810 keyboard, which displays the same behaviour.

This was originally reported downstream, in Ubuntu 13.10: https://bugs.launchpad.net/ubuntu/+source/upower/+bug/1245287

I am not the downstream reporter. I have experienced this bug in Ubuntu 14.10 and 15.04.

Here's what I see in syslog:
