The system detects battery without any problems and battery indicator works fine in KDE when I boot from Kubuntu 14.04 installation DVD. The battery indicator works fine after I install Kubuntu 14.04 to hard disk, but stop work after I did 'dist-upgrade' on installed system.
Note for my last comment:

I hope this info helps to fix the bug.
