Chosen Solution
I have a Late 2008 Aluminum - MB466LL/A - MacBook5,1 - A1278. I have done all the steps Apple has told me to do which involves resetting things. I have tried using a new battery and new charger and still nothing. One of many problems are the battery life indicator button does not work or show any light at all when pressed. My charger shows it’s charging (orange light) but in a couple of minutes it turns green. The moment I disconnect the power my laptop immediately turns off. Was wondering if someone could tell me where to look internally to maybe see if there is something wrong?
Let’s us a better diagnostic tool to exactly the condition of the battery. Please download, install run and post your results using Coconut battery. https://www.coconut-flavour.com/coconutb… UPDATE 8/28/18 Thanks for doing the Coconut Battery. Your machine is not seeing the batteries at all. Lets look for connectivity errors. I would use a multimeter and check the continuity on your connector first : MacBook Unibody Model A1278 Battery Connector Replacement
