On a Sony Vaio CS11S if i unplug power i don't see any "ac_adapter"
messages in the lshal output, just this line:

HP Pavilion dv6000t with same problem. For me this is really difficult
because I never get a low-battery warning and my auto-suspend never

Workaround seems to work for me, however. Thanks!

Thanks Moebius, I put those on the sh files and the circle is now
complete.
Yeah, got guidance configured that way already, the problem is well, if HAL
doesn't know the laptop is unplugged guidance obviously can't do anything at
all, not even change the governor. At least on my laptop! So nothing
Luis,
for me hal changes the CPU freq scaling governor too.
However, you cannot edit the file
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor until you are in a root
environment (sudo will not work). So, to edit the file, just type:
sudo -i
echo "powersave" > /sys/devices/system/cpu/cpu0/c
Moebius, your workaround works lovely :) However there's one thing it
doesn't change: the cpu freq scaling governor.
So I was trying this out on the command line:
sudo echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
but I get a "permission denied" error (using sudo wtf)...
Thanks Moebius, your workaround worked like a charm.

I don't understand why this hasn't been fixed yet. The worst part is that it
used to work fine until a change in hal happened, and I reported the bug
like a week after.

Guidance-Power-Manger doesn't recognize if mains is plugged out and
battery put in (to save battery lifetime I always plug the battery of if
it isn't needed) in hibernate/suspend-to-disc mode. I have to restart
the power manager that the battery is detected and the battery profile
gets enabled.

HAL does detect when power is unplugged. lshal -m shows correct output but the
command
hal-get-property --udi `hal-find-by-capability --capability ac_adapter` --key
ac_adapter.present
returns true in both cases (plugged or unplugged)

Well, sort of :) unplugging from mains has got the effect of changing the
screen brightness straight away, however the CPU governor takes a long while
to switch, if it actually does :)

I've got the same problem on a VAIO FZ160E. Seems to be a common problem
on Vaios : see bug #216345 .
Hal reports if battery is charging or discharging as well as the
remaining power. Maybe guidance-power-manager should rely on those info
to switch between power management policies.
Any chance it
I think it's a hal issue that has to be solved there.

The problem is, that your AC adapter is reported as present (eg. plugged

Can I please have you provide the output (if any) of the following command:

Can you provide "lshal" when plugged and when unplugged, to see if HAL
has proper information?
You can also run "lshal -m" and plug/unplug power supply to see if
anything is printed to console output.
