Incorrect time estimates on battery charging with HP2133

Hi all,

A little while ago I installed Opensuse 11.4 to my HP 2133 minilaptop. Now when the very first time I ran out of battery and started to charge it from empty I noticed that the time estimates of the charge are not accurate. Actually, It is remaining constantly at the point where it claims that my battery is fully charged in 2 minutes.

Does anyone know where I can report this bug or if this is already something known?

Also a screenshot about this:
