I've got a 12" PowerBook (1.5GHz), and just wondered if this is a known issue with iStat Pro & the 12" or not.

You'll notice that the meter says the battery has done no cycles, and the health is at 0.

I'm running Leopard (10.5.0, haven't done updates yet), and the computer's got 512 MB ram, and is booted off an external drive (don't ask, just… don't ).

If I look in system profiler, it tells me the battery has done 467 cycles, doesn't mention a "health" percentage or anything though.

If you need more information i'll be happy to provide it.
