Bluetooth keyboard battery interpreted as laptop battery

Bug Description

My Logitech DiNovo Edge keyboard's internal battery status is available in:

for the first time ever in Ubuntu 12.10. This would seem like a good thing, except that upower indicator reports it as a regular laptop/system battery, and even proposing to power off my desktop system if the keyboard battery happens to drain completely. That is unacceptable behaviour. I rectified it by manually editing settings-daemon power settings with dconf-editor, so the critical action was set to "nothing". (The regular power system settings GUI would NOT let me select this value, which is pretty strange.)

Here's what upower says:
$ upower -d

While having apport collection info about upower, it made the kernel crash with nullpointer deref in kernel proc khidpd. Reboot failed, kernel was semi-hung afterwords. I suspect the crash might be triggered by reading/probing stuff about bluetooth or whatever. I have no time at the moment to report this as a separate bug, sorry. Traces appended below.

Looks like the kernel crash I reported above is actually bug 888828.

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

Changed in upower (Ubuntu):
status: New → Confirmed

Hello there,

I have this issue too.
Notice that with the Bluetooth USB dongle shipped with the keyboard, the "wrong" battery disappear and the keyboard is working fine.
So I am keeping the USB dongle plugged in, as Ubuntu do not work well with the laptop bluetooth device connected to the DiNovo Edge. With the dongle, I can let the bluetooth-wifi hard switch on, anyway. At least it does not interfere.

Please note problem also exists with other devices; i have a cheap bt mouse from DX and a Genius mouse/presenter both show the same behaviour descibed here.

David Morris (dmorris68) wrote :

Same problem with my Razer Pro|Click BT mouse on my Sony VAIO's built-in BT radio. This looks like a bug in the Unity battery applet, not in upowerd, but I could be wrong. upower-d displays the mouse battery with the proper device name and "no" to power supply (the laptop battery reports "yes" to power supply). But when I open the battery info app from Unity, it shows the mouse as a laptop battery. Not only that, but the "default" battery meter displayed in the Unity menu bar is for the mouse and NOT the laptop battery. So I have to click it to see the laptop's battery level.

I played around with several udev rules and inspected the upower source code. It appears that the kernel (in my case 3.7.0-7-generic) reports the device with the subsystem 'power_supply' with type 'Battery':

Reading the source code for ./linux/up-device-supply.c, it seems that upower doesn't expect CSR devices to be in the kernel, and therefore setting the kind as UP_DEVICE_KIND_BATTERY.

A udev rule like the following doesn't convince upower otherwise:

KERNEL=="hid-00:07:61:F7:60:01-battery", SUBSYSTEM=="power_supply", ENV{UPOWER_VENDOR}="Logitech, Inc.", ENV{UPOWER_PRODUCT}="diNovo Edge", ENV{UPOWER_BATTERY_TYPE}="keyboard"

For me, it affects me with the Lenovo Bluetooth Laser Mouse connected. There's no dongle, only connected to the internal bluetooth of my ThinkPad (it's a broadcom chip, but I don't think it's important). And sometimes, Ubuntu thinks that the battery is going dead, and shuts off!!! It's REALLY frustrating and unneccesary, because the laptop battery actually has 4-5 hours left of charge.... Also it displays the bluetooth mouse battery in the statusbar instead of the main battery, which is really strange and annoying.. I want Ubuntu to notify when BT mouse battery is getting low, but not turn off the computer by mistake :/ You know?

I'm having the EXACT same problem as David Morris three comments above!

Ralph Meijer (ralphmeijer) wrote :

@PnG: while this is marked as a duplicate of #1066208, I very much doubt it is, given its fix and my comments above (#8). The Logitech diNovo Edge is recognised as neither a keyboard nor a mouse in Raring's daily (12.10.6daily13.01.25-0ubuntu1) but as a laptop battery that is not a 'supply'. This device is primarily a keyboard with a small touch pad.

Besides that, upowerd doesn't seem to get the actual values right either. Fully charged it barely reaches 20%.

Here is an ugly patch that works for me (Logitech K810):

Since this report is identified as a dupe of #1066208 and this issue is marked as fix released, I opened a new issue only regarding the keyboard battery being marked as a laptop battery: #1195840
