laptop battery meter not working?

Hi! I'm using mandriva linux 2007 on a HP compaq nx6115 notebook. i have a problem with my battery meter (Klaptopmonitor) in KDE. when i boot my laptop pluged in to AC power i see that the laptop monitor is working, when i plug it out of the AC power he change to battery... but if i'm working for 1 hour and i check the battery it seems to hang because it says that the battery is still 96% full... and when i plug it in again it doesnt switch back to AC power anymore. does anyone know how to solve this problem?

i just figured out that the meter is working... until i change something to the taskbar nex to the clock... if i start Amsn or skype there is coming a new icon next to it... when that happens the battery meter starts hanging and doing nothing anymore:???:
PS. i tryed to restart the battery meter but that doesn't work.


can somebody help me please?
