gnome-power-manager not detecting battery changes

[Rafael Rocha]

Binary package hint: gnome-power-manager

gnome-power-manager version: 2.30.0-0ubuntu1
Ubuntu 10.04.01 LTS
Acer Aspire 5745-3428 recently bought
SMBIOS 2.6 revision: 8.240 - according to dmidecode

g-p-m does not notice the power cable presence/disconnection, it shows the battery icon as fully charged all the time; under its properties is shown the battery as 100% charged all the time and the battery icon does not indicates the battery discharging.
g-p-m is using preferences as the laptop is pluged on charger.
Running acpi returns message of "rate information unavailable"; running acpi -a shows "Adapter 0= on" all the time, even if the power cable is off; running acpi -bi shows "Battery 0=unknown...;
So, the power manager and acpi are not detecting the battery discharging and both of them indicate the power line cable as on all the time.
YACPI command returns that AC ADAPTER is on, even if it isnt.
All the system power monitors indicates that the power cable is on all the time, so there is no difference when the notebook is using batteries or charger.
The only indicator that is OK is the laptop charging light.
Tried booting with ec_burst=1 and acpi=force parameters but there was no change.

I just cant use the ubuntu with the laptop unpluged cause i dont know the battery status.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GNOME Power Manager is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back? Thanks in advance.

Hello,

First of all sorry for the lack of update on the bug.

Actually i have updated my bios version and the problem is almost gone.
The only issue now is when i unplug the power cable, so the manager detects that i have unpluged it and shows the battery status, but this status remains the same and dont decrease with the energy level.

I havent downloaded Maverick yet, when i do so i will report back.

Thanks for the concerning.

Is this bug repaired? You say it is, but I still have similar problem on my Fujitsu Amilo Pi3560; i'm using Ubuntu 11.04.
