ubuntu 11.10 unity hibernate when battery full

[garvin timmann]

in Ubuntu 10.04 gnome had a bug that was worked around but cannot be done in Unity in 11.10
IN GNOME:
Whenever I unplug my laptop from AC power, I get a window popping up that says "Laptop battery critically low. Computer will hibernate very soon unless it is plugged in." And a little notification pops up that says that the laptop has 5 minutes until the power drains.

But when I click on the battery icon, it says that I have 4 hours of battery time remaining. My battery is a six cell battery with 97.1% charge capacity. I have no idea why it's saying that it's almost out of power. That doesn't come up if I turn on my laptop after I unplug it.

Does anyone know why it's coming up or how I can disable it?

WORKAROUND:

If you open up a terminal and run gconf-editor, go to apps, navigate to gnome-power-manager, click on general, and then uncheck "use_time_for_policy", it will fix the warning messages. Some people (myself included) were also having trouble with it automatically hibernating/suspending when unplugged, and this fixes that issue also.

IN UNITY THERE IS NO GNOME-POWER-MANAGEMENT SO HOW DO WE STOP THIS?

Status changed to 'Confirmed' because the bug affects multiple users.

Happens to me as well. Dell D620. Upgraded from 11.04 to 11.10, then the problem started happening.

I have the same problem.
Ubuntu 11.10 32 bit
netbook msi wind

Also, when I suspend, if I unplug from AC power, when I resume the system crashes and I have to turn off and turn on. If don't unplug from AC power, it resumes ok.

It seems to be a duplicate of #860427 and #531190.

Problem began when I upgraded from 11.04 to 11.10. Toshiba Satellite P205D-S7802

Same here. Since Upgrade from 11.04 to 11.10 my HP Pavillion dv9913cl goes immediately to "Battery Critical" when I unplug from AC. If I am lucky it actually completes hibernation, but half the time just cuts off before it has completed.

battery critically low popup - computer halts sometimes and need hard reset.

Windows 7 install gives normal battery life

Here's how to do it in Unity (you'll need to install dconf-tools): http://askubuntu.com/questions/92794/how-to-change-critically-low-battery-value
I'm not very clear yet - is this an ACPI-BIOS bug or not?
It also affects my laptop - Lenovo Ideapad U450p

Bug confirmed : Ubuntu 11.10 64bit on Toshiba Satellite L500-120 ( german model; phoenix bios , v2.10 ) , same issue : when A/C is unplugged, Unity Gnome pops up the "critical" warning and the Laptop goes into suspend mode in such a rapid time that I can't stop it.

Workaround : use the terminal commands given here solved it completely : http://askubuntu.com/questions/92794/how-to-change-critically-low-battery-value

Otherwise the ubuntu 11.10 works beautiful without any issue on this machine, congrats -- looking forward to 12.04 .
