Flood of "ACPI action undefined":laptop not handling AC adapter state?

Soukyuu · 2014-04-19 16:51:16

Hello,

The laptop is an old Toshiba dynabook CX1/212CMEW, Celeron M CPU, so it doesn't have most of the power saving features. I frequently see the following message when monitoring with journalctl -f

Looking around, it seems to be related to the AC adapter somehow. I have the default handler.sh, modified for also handling the brightness keys:

#!/bin/bash
# Default acpi script that takes an entry for all actions

    button/power)
        case "$2" in

It appears whether the laptop is running on battery or on AC. When unplugging, the following appears in the log:

Apr 19 18:41:47 Elder kernel: toshiba_acpi: Unknown key e00
Apr 19 18:41:47 Elder logger[2226]: ACPI action undefined: ACPI0003:00

Plugging in shows the following:

Apr 19 18:44:31 Elder logger[2362]: ACPI action undefined: ACPI0003:00

I expected to see :01 while either plugging or unplugging the AC adaptor... Though (dis)charging state seems to be correctly reported to LXDE's battery widget.

Quite new to linux, so I'm a bit lost on how to "fix" that. Or can I safely ignore that without any side-effects on the battery? I can provide more info if you tell me where to get it.

You could ignore it, but I suggest you adapt that default handler.sh to ignore events with PNP in them. That would prevent flooding of your journal.
