That's interesting. If a fractional recharge counts as the same fraction of a power cycle, then it should not matter how frequently or infrequently the battery is charged, at least with respect to the impact of power cycling on overall battery longevity. If that's true, and I'm certainly not saying it isn't, that seems like good news for those of us who have been trying to monitor battery status and wait until the battery is low. Thanks for the information. Gregg _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
