What computer brand/model do you have?

Here's a workaround you can try to disable the reboot (but doesn't deal with the battery monitor part): http://askubuntu.com/questions/61390/why-does-my-laptop-think-my-battery-is-dead

thanks bcbc for the help.
I saw that people have the same problem in the above link. I installed gconf-editor but when ı go /apps there is no gnome-power manager. what is the problem with my laptop?

my laptop's brand is Monster FL90

It's not a problem with your laptop. It does sometimes help to search on specific models because sometimes you'll find specific workarounds for that model. In this case, it appears to be a problem in a specific package.

You shouldn't need to install the gconf-editor. From the bug report you can run:
gconftool-2 --type bool --set /apps/gnome-power-manager/general/use_time_for_policy false

I just wrote that in the terminal, gconftool-2 --type bool --set /apps/gnome-power-manager/general/use_time_for_policy false

nothing changed. can you help me more on this please ?

Hi, I had to wait to get to my 11.04 install to try this. I followed the instructions in the 'askubuntu' link I provided and, apart from a slight typo, it was as specified.

Alt+F2, gconf-editor
Then navigate by clicking on the folders:
/apps/gnome-power-manager/actions/critical_battery

And edit the value to "nothing"

After that, when you go to System Settings, Power Management, under the "On Battery Power" tab, you'll see under:
When battery power is critically low: Do nothing

Using the gconf-editor, you can also navigate to: /apps/gnome-power-manager/general/use_time_for_policy
and uncheck that. It should have the same effect as running the command gconftool-2 .... shown above. Either should work.

If you've double checked and you're still having issues please confirm what release you are on by running from a terminal (Ctrl+Alt+T):
cat /etc/lsb-release

and paste the results back here.
Thanks

hi.
thanks for the help. I tried what you suggested before. but, the problem is when ı go /apps/ in gconf-editor there is no such a thing, gnome-power-manager. that is the problem my friend.

this is the output from terminal :

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=oneiric
DISTRIB_DESCRIPTION="Ubuntu 11.10"

Okay, you said you had 11.04, and 11.10 is entirely different. See this
answer here on how to do it: http://askubuntu.com/a/83225/14916
