Battery not charging or seen by OS
Here's my problem,
The Macbook is functioning fine, but the battery shows a black cross. I can't boot without the power adapter connected but once started, even right in the beginning, i can disconnect the power and it boots up fine. The magsave connector is green.
Ive done the following step,
Reset the pram and smc even disconnected the pram cel for a wile.
Tested the battery and adapter on my other macbook (same model) And finally swapped both battery cable and mac connector with the working macbook. None solved the problem.
So i'm thinking its the logic board. and i would think this is reparable if i know witch component is the most common to fail.
Dos anyone have an suggestion?

+ your English is flawless, I wish your problem was the same. What system are you running, this is a hard problem in case you didn't know.

Tanks for the quick reply and compliment.
I'm running 10.6.6 but also tried previous versions. By hard problem i guess you mean hardware.
I'm almost curtain thats the case but simply buying an new logic board seems very expensive.
In the netherlands the repair prices are skye high and i've found DT&T whats seem resonable but the
cost of sending the part is making it costly unfortunately.
So i'm trying to obtain information,Diagrams scheme's so that i can fix it myself!

I agree, this is a hard problem to solve. There are no known good sources for schematics for Logic Boards. I also agree that it might be a component on your board being at fault here. When you say that both MacBooks are the same exact model, are you sure about this?

Have you tried a fresh install of OS?
由 Majesty 完成的
yes i've tried a fresh install. someone answered something about if i'm sure its the same macbook and another about a fuse on the logic board but these answers i don't see anymore?
The reason i think its the same is because its the same duo core and speed. and both are E star.
The battery connectors are the same. the serial nr of the broken logic board is W87420TSZ5Z
And the one that's working is W8734089Z5W If there is a difference in the dc board i would like to know this.
furthermore tot the person wich said something about the fuse,,, i've made detailed high resolution pictures and posted them online an can be seen here
Logic board detail
I hope you can tell me in what area i must look the fuse nr you mentioned i did not find
Thanks so far for the great input!!
PS, the pictures can be downloaded then you can zoom in more!
