Help with complicated battery issues.

Some time ago my Model A1181 Macbook started to refuse to charge its battery. I have replaced the battery (new) and the battery interface cable/board (used) to no effect.

The magsafe connector is almost always green. It is not green for about a minute after boot or a minute after I plug in the battery. It thinks for this minute and then decides the battery does not exist. Black X. Despite this, starting with a running laptop plugged in to AC power with a charged battery.... the computer draws power (runs happily) from the battery it doesn't think exists when you unplug the AC power. I have tried all of the various resets and battery updates.

Is there anything which could be broken on the motherboard or hacked to become fixed?

From system profiler during the minute where its thinking about whether the battery exists:

Resolution

Shut down, then remove and reinstall the battery. Test for the issue(s) again.

Connect the MagSafe power adapter (if you haven't already) and see if the behavior continues.

If the issue(s) persist, download and install the Mac OS X v10.4.9 Update.

If the issue(s) persist, download and install Battery Update 1.3.

If, after installing the Mac OS X v10.4.9 Update and Battery Update 1.3, a black "X" still appears in the menu bar, follow the steps in MacBook, MacBook Pro, MacBook Air: Battery not recognized after being fully drained.

If the battery charge status still shows zero percent, yet appears to show a nearly full charge shortly thereafter, see Calibrating your computer's battery for best performance.

i have never heard something like that, if the battery was new, it should do that, but the there is a ten hour battery, if you bougth that type of battery your system might not want to reconized because that battery is only for new intel macbooks(2009-2010) go to apple.com/support
