I have a 2.4ghz MacBook A1181 (Purchased August 2008) in that runs 100% perfect off charger, but when you install battery it shuts off though the sleep light turns on. When you start up with the battery alone it gets to the point of the blue login screen them shuts off but again its fine off ac. I don’t have any spare energy star battery connectors to swap out so before I buy one wanted to see if my macbook teachers (abceller, lemerise, meters) etc had any ideas. Thanks guys!
First I would try a known working battery connector/sleep sensor board and also check the 20 pins socket where the board connects to the logic board for any abnormal color or corrosion. If the issue is caused by a liquid spill in this area then the main board could be damaged (often an issue with liquid spilled units). Make sure your battery is not the culprit by testing it on another macbook or try a known working battery in your macbook. If you have a multimeter I think ABCellars could guide you testing the battery connector voltage. Pretty sure he’s got the voltage values. MacBook Battery Connector/Sleep Sensor (Energy Star)
