guidance doesn't find any battery if battery is not present on startup

[daimadoshi85]

Binary package hint: kde-guidance-powermanager

After upgrading to Hardy guidance doesn't recognize battery when powered by AC from startup, and Kubuntu freezes if I try to insert battery. When otherwise battery is inserted on startup, everything works fine.
I've done this screenshot to explain what I mean. This is the situation if I don't insert the battery on laptop. Battery is not recognized (also the icon is different) and if I want to use it I must restart with battery inserted.
Package version is:

That is how it handles batteries as it is now. It doesn't really handle removal/insertion of batteries that well.

This bug should be marked as wishlist.

[Scott Kitterman (kitterman)]

No. It should recognize the battery on startup.

Please run the power manager from a konsole shell.

1. Exit guidance-power-manager (right click on the icon and select quit).
2. Open a konsolse shell.
3. Type guidance-power-manager

If that produced any output, attach that to the bug.

For your initial startup errors, look in your user's .xsession-errors for anything that appears power-manager, hal, or dbus related.

@Luca
Am I understanding right, that the battery is not present (eg. physically removed) when booting?

And does it work if you are running on A/C when booting and the battery is inserted?

[daimadoshi85 (dragon-fog)]

@ Awen Yes. You're right. Battery is not present phisically when booting. and the situation is like my screenshot.
If I insert it later there are two consequences :
a - System doesn't freeze, but battery is not recognized. The situation is the same of my screenshot and doesn't change.
b - System freezes.

[daimadoshi85 (dragon-fog)]

Obviously happens consequence a OR consequence B.

[Andreas Wenning (andreas-wenning)]

Thanks for clearing that up.

Then this is a wishlist bug. g-p-m doesn't actually handle battery insertions.

The system freeze however has nothing to do with this or guidance-powermanager. I will suggest you look in /var/log/syslog or some of the other logs to see if you can find a cause for the freeze and report it as a new bug.

[daimadoshi85 (dragon-fog)]

Normally the system doesn't freeze, but if it will happen another time I will notice you.
I want to specify also that if I insert the battery and remove A/C, the laptop works without say battery's remaining time.
I hope you will solve this behaviour :)
Thank you

I have a very similar problem: If the battery is not present at startup, g-p-m does not detect if it is inserted. My system does not freeze. Only an exit of g-p-m in the tray bar and a manual start in a console fixes the problem.

But: This "feature" was available with Feisty, so it is quite annoying that it no longer works with Hardy.

PS: Once a restart of g-p-m is done the battery can be removed and readded without problems, even after a suspend oder hibernate.

Guidance Power Manager has been removed from Kubuntu 10.04 and onwards since it is unmaintained. Unfortunately, this means that no new features or bugfixes will be made.
