MacBook won't run on battery power
The battery icon shows an X at all times. I installed a brand new battery and the problem still persists. I tested the new battery on another MacBook and it shows a full charge and works just fine. The light on the power adapter turns from green to red as soon as the battery is installed but still only ever shows an x for the icon. I also tried the smc reset - no luck. Any ideas??
Known issue with
contacts between battery connector board and logic board... Remove the battery connector board, clean the pins on the connector and contacts on the board with dielectric cleaner and a small stiff brush. 99% iso alcohol after will speed drying. Wait 72 hrs to reassemble after cleaning unless you speed the process with a desiccant. If this fails you may need a new logic board.
