Comment 26 for bug 99356

I have installed Ubuntu Feisty Fawn 7.04, without any changes. Didn't
compile myself, etc... All default. Then using apt-get, installed xfce
on top of it. To avoid repeat bug, turned off acpid, and turned on apmd
in Xfce Menu--> System--> Services. Now repeat bug disappeared, but
battery applet shows 50% of battery all the time. Even if new battery is
attached and filled. I DID NOT SUGGEST to do so to anybody else, neither
I can take on the responsibility for others, since I am noob myself :-)
This was just the information on what I have done.
Good luck and please let me know, if solution is found to make battery
applet working.
