battery monitoring doensn't update

[ndlarsen]

Battery power status only gets updated on insertion and removal of the ac adapter on an Acer Travelmate 4500 series notebook. Other than that is't stuck at the same level. lshal -m only displays activity on the above mentioned events. Contents of /proc/acpi/battery/BAT1/ and /sys/class/power_supply/BAT1/ displays same behavior.

While on ac, doesn't get updated neither on ac nor not.

I hope the provided information is sufficient, if not please let me know what might be needed.

[ndlarsen (usenet)]

I see this report has been assigned to gnome-power-manager. More likely this is an acpi or kernel bug as it affects the power monitoring plug-in for the xfce panel as well.

[ndlarsen (usenet)]

It's an issue as well on linux-image-2.6.28-8-generic.

assigning to acpi then, thanks.
