laptop goes standby after gnome login on battery

[ubuntic]

I installed Karmic-beta (9.10) ubuntu on my laptop SAmsung r-50.
In the standart installation with succesfull configured wpa.

I charge the battery full and start the laptop with both battery and AC are
plugged in. I login into gnome desktop. Until now any problems.

But if i plugged out the battery, after a few time the system goes down without
any warnings.

The failure is that the system goes completly down (hilbernate or suspend, i
don't know), but only the blue-led on the front of the laptop is blinking.

I need to restart. With only AC booting no problems.

The same if i boot with only the (full)battery until "gdm login window" no
problem, but after i login into gnome a few time later (5sec - 1min.) the
system close the screen session and goes standby or hilbernate.

But on kde-desktop i can login and can work with battery without ac.
And on jaunty standard installation, i haven't any problems with battery plugging

During the installation of Ubuntu Karmic i haven't any problems.

Steps to reproduce:
1. Plug the power cable an battery
2. Start the System and login into Gnome
3. work a little bit and plugg out the battery (working until putting out, no
probs)
4. On my laptop few sec. later my screen session is going to close and
goes standby (hilbernate or suspend) because the blue-led is blinking.

The same failure: (starting with only battery)
1. Plug battery
2. Start the System and login into Gnome
3. I can't work a long because after a few seconds Point 4 happends
4. On my laptop the, few sec. later my screen session is going to close and
goes standby (hilbernate or suspend) because the blue-led is blinking

thanks all

I have have the german language configured during Karimc installation, if its importent.

I installed 9.04 back and see no standby problem. (karmic apha 5)
Then i install karmic alpha 6 and the problem is here again. Same problem in live Desktop and Alternate Ubuntu Karmic apha 6.

Same problems in Karmic beta

After the update since yesterday the standby failure is in the whole cleared, im happy.

The only thing is that the screen becomes black during pluggings in/out battery and AC, that is really a smaller problem as going standby.

Sincere thanks are given to all

On my sony vaio vpcw11s1e, I can confirm this bug. unplugging the power cord in gnome makes the system go to standby. I just bought the computer and put Ubuntu 9.10 on it (fresh standard install of the final version):
kirstin@vaio:~$ cat /proc/version
Linux version 2.6.31-14-generic (buildd@rothera) (gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu8) ) #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009

the acpi event it receives on unplugging is:
processor CPU0 00000081 00000000
processor CPU1 00000081 00000000
battery BAT1 00000080 00000001

This is probably connected to an issue with the gnome-power-manager or pm-utils, since it doesn't happen in gnome-safe mode or when I use another WM such as fluxbox.

Same problem on my old Toshiba...Karmic goes into stand-by if I boot the laptop with ac connected and then I unplug it; or
if I boot on battery and then I plug in the ac adapter..

[Alessio "Spinus" Moscatello (spinus)]

Sorry...now I'm not sure that this is a bug of pm-utils, because I've find out that HAL wasn't running on my laptop (see attached pm-suspend log)..
I've killed gnome-power-manager, started hal and restarted gnome-power-manager: now my laptop doesn't go in stand by if I unplug the ac cable...so I will try to find out why hal doesn't start at boot time...

[Alessio "Spinus" Moscatello (spinus)]

I've done other tests...and it seems that the issue goes away simply restarting some times gnome-power-manager...
In addiction I've discovered that if I connect and disconnect ac adapter while I'm on the terminal the laptop doesn't go into stand-by, but as soon as I switch to GDM it goes on stand-by!

I have the same problem on my HP Pavilion DV 1000
If I start with power plugged and then just unplug the power,my laptop goes to suspend mode, after the wake up his just freeze and needs to hard reboot, the same picture is vice versa
