The battery that does not allow you to start up your Duo has a short in it which is why is stops the unit from powering up...and it should be disposed of in a proper manner, as all batteries. The battery which gave you all indicators grey except one was actually almost all full. when the grey indicators are filled, that means the battery is full, but to be safe it is best to let the battery full charge overnite. The other thing that is a good idea is to recondition the battery which you can do with most powerbooks. Just do a search for battery in your FIND menu and it should come up. If not, go to Apple.com and download a free version of it. Alan ---------- Duo/2400 List, The friendliest place on the Net! A listserv for users and fans of Mac subportables.
