Battery and charger cannot work same time

[rogery]

Hi friends, anybody experiences same problem with me?
My Macbook white is 2008 model. Whenever I insert the battery, charger stop working (no light at all) and also not charge. Take out the battery, charger shows green light and works as normal. I bring the battery to test with other Macbook white same model, it works very well. I also test the charger with other Macbook, also working fine.

It means that both the charger and battery are in good condition, but simply cannot work together. Anybody knows why?

Try resetting the SMC. Check to make sure the battery is properly seated and that connectors are clean and undamaged. Also check the adapter connection very carefully, to make sure the connection is clean and secure. If none of this helps, the other primary charging component is your logic board. Take it to Apple to have it checked.

This should answer most, if not all, of your battery questions:

I see. Thanks for your comment.
Anybody knows how much it costs and how long it takes to change the charge circuit?
Btw, I also want to upgrade RAM and HDD will it be very costly?
thanks

If the logic board needs to be replaced, it can run around $700.

Btw, I also want to upgrade RAM and HDD will it be very costly?

It depends on how much RAM and which HDD you select. Just shop around, as prices vary widely. Of course, you can easily replace both yourself, so there's no labor charge involved.
