Mmm.. me too. I think I was misled by the whole "don't ever totally
discharge your lithium battery" thing. I thought the whole memory
effect thing was NiMH/NiCd specific. Seems it's just not permanent
with Li-ion.
My iBook stays on charge pretty much all of the time. That regime
has just changed. Cheers Tim. :)
It's a shame the charger can't be controlled from the OS... if it
could, a program could be written to do a discharge cycle while still
staying on mains power. :(
