Problem Description:
Event "ac_adapter ACAD 00000080 00000000" doesn't appear in output of
acpi_listen when I unplug AC adapter. After several plug in and plug out event
appears. For example:
battery BAT0 00000080 00000001
battery BAT0 00000081 00000001
ac_adapter ACAD 00000080 00000001
battery BAT0 00000080 00000001
battery BAT0 00000080 00000001
battery BAT0 00000081 00000001
battery BAT0 00000080 00000001
ac_adapter ACAD 00000080 00000001
battery BAT0 00000080 00000001
battery BAT0 00000081 00000001
battery BAT0 00000080 00000001
battery BAT0 00000080 00000001
battery BAT0 00000081 00000001
ac_adapter ACAD 00000080 00000001
battery BAT0 00000080 00000001
ac_adapter ACAD 00000080 00000000
battery BAT0 00000080 00000001
Exept it value of /sys/class/power_supply/ACAD/online is still "1", but value
of /proc/acpi/ac_adapter/ACAD/state is "off-line".
My notebook is HP Pavilion dv6700t us.
I have latest BIOS from HP website.
This problem appeared also in Gentoo (gentoo-sources) and ARCH.
Steps to reproduce:
Start up acpi_listen command and plug out AC adapter.
