Bug description

I was inspecting the .xsession-errors log file and noticed there are a lot of unexpected csd-power-WARNING lines:

(csd-power:1213): csd-power-WARNING **: 15:25:30.594: enum unrecognised: 17
(csd-power:1213): csd-power-WARNING **: 15:25:30.594: enum unrecognised: 17
(csd-power:1213): csd-power-WARNING **: 15:25:30.594: in an undefined state we are not charging or discharging and the batteries are also not charged
(csd-power:1213): csd-power-WARNING **: 15:26:00.675: enum unrecognised: 17
(csd-power:1213): csd-power-WARNING **: 15:26:00.675: enum unrecognised: 17
(csd-power:1213): csd-power-WARNING **: 15:26:00.675: in an undefined state we are not charging or discharging and the batteries are also not charged

I investigated a bit and I have a guess about this.
My notebook (LENOVO IdeaPad 3 15ITL6) has a set of custom power policies in the BIOS, where one can set how much to charge the battery - in my case I have it always plugged so I choose the so called "maximum protection" option.
This makes it so it never charges it more than 60%.
My guess here is that it's reporting an APCI value of 17 and this is not understood by csd-power-manager - maybe it's a non standard value.

Can this be handled more gracefully, without spamming the logs?

Steps to reproduce

Install Linux Mint 22.1 Xia on a LENOVO IdeaPad 3 15ITL6, update all packages, check .xsession-errors log file.

Expected behavior

No csd-power-WARNING in the logs.

Same here with a similar system:

I looked into the log messages and it seems that enum unrecognised: 17 comes from the fact that in gpm-common.c
there is no case branch for kind = 17, which corresponds to UP_DEVICE_KIND_HEADSET.

Since I’m using a Bluetooth headset with battery level indicator, this would explain why the message shows up. Can anyone confirm if they also had a headset connected when the error appeared?

As for the in an undefined state... warning, gpm-common.c suggests that it is triggered by an unhandled power state, such as UP_DEVICE_STATE_UNKNOWN. This also seems related to the headset, as there's no state reported when I run upower --dump with the headset connected.

The laptop battery being in "conservation mode" is an alternative hypothesis (my system also has that feature), but given the earlier finding, the headset explanation seems the more likely one.
