My system: Thinkpad Edge 13", Intel Version, OpenSuse 11.3 (64bit), KDE 4.5.3

Hello
when I start up my Thinkpad without having the AC adapter plugged in, Powerdevil Plasmoid and sysinfo:/ deliver the following information:
Battery is recognised correctly including charge level, battery time remaining and battery is discharged. But the AC adapter is recognised as plugged in.
Terminal output as follows:

Code: Select all

cat /proc/acpi/ac_adapter/ACAD/state
state:                   off-line


According to this, the ACPI interface recognises the AC adapater state correctly.
Once I plug in and pull out the adapter, Powerdevil shows the correct information; including AC adapter is not plugged in.

What can I do to have Powerdevil show the correct information since start up without pulling in and out the AC adapater?

Thanks for your support!

Please do the following:

Code: Select all

lshal -s | grep power

Take the text of the AC adapter item listed there, and run the following:

Code: Select all

lshal -u <ac adapter name>

Then post the output of both the commands here.

Example:

Code: Select all

ben@bianca:~> lshal -s | grep power
computer_power_supply_battery_BAT0
computer_power_supply_ac_adapter_AC0
ben@bianca:~> lshal -u computer_power_supply_ac_adapter_AC0
udi = '/org/freedesktop/Hal/devices/computer_power_supply_ac_adapter_AC0'
  ac_adapter.present = false  (bool)
  info.capabilities = {'ac_adapter'} (string list)
  info.category = 'ac_adapter'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'Generic AC Adapter Device'  (string)
  info.subsystem = 'power_supply'  (string)
  info.udi = '/org/freedesktop/Hal/devices/computer_power_supply_ac_adapter_AC0'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'power_supply'  (string)
  linux.sysfs_path = '/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/ACPI0003:00/power_supply/AC0'  (string)

Thanks for your reply!

I started the system without Ac Adapter plugged in; output is as follows:

Code: Select all

~> lshal -s | grep power
computer_power_supply_battery_BAT1
computer_power_supply_ac_adapter_ACAD

~> lshal -u computer_power_supply_ac_adapter_ACAD
udi = '/org/freedesktop/Hal/devices/computer_power_supply_ac_adapter_ACAD'
  ac_adapter.present = true  (bool)
  info.capabilities = {'ac_adapter'} (string list)
  info.category = 'ac_adapter'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'Generic AC Adapter Device'  (string)
  info.subsystem = 'power_supply'  (string)
  info.udi = '/org/freedesktop/Hal/devices/computer_power_supply_ac_adapter_ACAD'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'power_supply'  (string)
  linux.sysfs_path = '/sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0003:00/power_supply/ACAD'  (string)

There is the problem... HAL believes the adapter is connected, hence KDE does also. I suggest you contact your distribution for assistance, looks like a bug in HAL.

Thanks for your reply. I will inform the openSuse guys.

I did a little research on hal and found a workaround. Calling the following command at startup fixes my problem:

Code: Select all

hal-set-property --udi '/org/freedesktop/Hal/devices/computer_power_supply_ac_adapter_ACAD' --key ac_adapter.present --bool false

I put it in a script that utilizes /proc/acpi/ac_adapter/ACAD/state and it should be fine.

Tanks for your help!
