[ltp] KDE Battery widget reads 11% w/ charged battery

[Jeffrey L. Taylor]

My new T520 has been working fine with OpenSuSE 11.4 and KDE installed.  Up
unitl Wednesday, the battery widget in the panel read 98% charged.  Starting
sometime Thursday, it turned red and reads "11% (charged)".  It continues to
read the same after a couple of hours of suspend to ram and overnight suspend
to disk.

Comparing this 6 cell setup to the 9 cell setup in my T41, this looks
reasonable given the change in capacity measurements from mWh to mAh.  Any
suggestions on how to reset the battery widget?
