Hope this is not a duplicate, but I don't see it in the digest. This one was submitted (Jeremy) before I replied to David. Thanks/bg

I was forewarned they may or may not even work, hence my experiment. I read somewhere to recharge them 24 hours before even using them. That has now been done with both batteries (the first battery described in first post above). The second battery: During the last 24 hours, the adapter light remained amber, so I was "hopeful" it was actually recharging the battery. The control strip even says (again) that battery is charged. However, when adapter is removed - out go all the lights! (all power lost). I also read the article above (thank you!) and did as it instructed (2nd battery). But date/time still remains 1/1/04, but instead of 12 AM, it says 12:25 AM (maybe that's from my previously resetting the clock yesterday?) > ...and then test with known good adapters and batteries (one at a time, if you > swap both at the same time, you won't know which fixed the problem).

I am thinking the adapter does work since it does power the ibook (even with "dead" batteries). And since it appears both batteries are "kaput," I am not able to swap with "known goods." But thank you for outlining exactly what to do.
