My understanding was that on well-designed machines, this would not be true. (Because the laptop would stop trying to charge the batteries once they were fully charged; for example, it is perfectly safe to leave nicad batteries in a Millenium battery charger for long periods of time, even after the batteries are fully charged). I remember reading in this news group that Toshiba computers (specifically, the T1000) are well designed in this regard. Can someone confirm or deny this? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Theodore Ts'o bloom-beacon!mit-athena!tytso 3 Ames St., Cambridge, MA 02139 tytso@athena.mit.edu Everybody's playing the game, but nobody's rules are the same!
