A few weeks ago, my MagSafe adapter burnt out. Someone else was using the computer, didn't notice, and the entire battery got depleted. Now, I replaced the MagSafe adapter. When I plugged it in, the MacBook worked, but the battery would not charge. I tried all the tricks, resetting the pram, getting the update, whatever. I then convinced Apple that the battery was bad, and they gave me a new one. So here I am, with a new MagSafe and new battery, and the thing still will not charge. The MacBook recognizes the battery, and it will run off the battery as well, but it will not charge it. I've tried other MagSafe adapters, tried cleaning the connector, tried taking the battery out and holding down the power button (while off), nothing works. I am hoping someone has a solution other than "buy a new logic board."

strung,
Well, the first battery I got did get completely discharged. And then it wouldn't recharge at all. So I suspected a bad battery, and had Apple replace it. Now, this brand new battery will not charge. Comparing what the system reports with the light indicator on the battery itself confirms that the % seems accurate. I started with 2 lights at about 34%, and now am at 1 light at about 16%. I have not tried running this battery flat because the 1st battery was already run flat.
Have you tried the steps in these two articles:

The first article doesn't apply, as I cannot calibrate the battery because it needs to be able to charge. And, the first battery was already fully depleted as said in the article. The second article also does not apply, as I don't have an X in the task bar, it shows it plugged in. And I have already tried re-seating the battery, taking it out, and resetting SMC.
One other update - I completely reinstalled OS X (having it revert to Tiger), and the battery will not charge still. Tiger does report something different though, it says "Calculating ... until full" and never changes. I installed that Battery Update 1.2, and it doesn't work either. It seems that the MacBook is probably entirely wonked. Good job Apple...
Thought I'd chime in here to say that I have the same issue and you're not alone.
I've got 2 MacBooks, which makes testing a bit easier. Both MagSafe adapters work fine on one MacBook, charging batteries and their LEDs light up fully, the other only ever has a dim green LED on the MagSafe.
Both batteries work fine - both MacBooks can run from them, but only one MacBook will charge them.
Like you I've re-installed Leopard, installed battery updates and reset everything I can think of.
The interesting thing about my broken MacBook is that it seems to have been cobbled together from parts. This is a white MacBook with black MacBook innards.
I know the MagSafe connector has been changed, so this only leaves the battery connector or the logic board.
I know there's some sort of small chip on the battery connector (I've had the affected MacBook totally apart) so I'm hoping this is fried and thus not creating a full circuit for charging (or something).
In the mean time, if you just want to get your batteries charging - a not so pretty method is to buy FastMacs U-Charge - it's an external battery charger. It should work well, I just need to get mine replaced because it's not working properly.
I'll be purchasing a new/used battery connector to try soon and will let you know what happens.
Sorry for the delay.
I've just moved house so I'm still getting bits sorted.
I sent my charger back to fastmac but haven't heard anything yet so I can't tell you whether it's a worthwhile buy or not. As for the battery connector, I'm waiting for a good deal to come up with one in the UK otherwise shipping will be nasty from the US.
Nope - sorry.
I bought a MacBook Pro. The MacBook sits there - still unable to charge.
It must be something in the charging circuit on the logic board, but I have no idea on which part - even if I did, repair (for me) would be difficult because all of the parts are so tiny.
I can only think that the faulty MagSafe shorted something out - I have no idea if my MacBook experienced this problem before I got it though.

Try resetting the SMU as follows:
If the computer is on, turn it off.
Disconnect the AC Adapter and remove the computer's battery.
Press and hold down the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the Power button to restart the computer.
