My MacBook Air Mid 2012 recently stopped working unless plugged into the charger. The battery appears to have disappeared, though Apple Hardware Test doesn’t find any faults. Coconut battery doesn’t find anything and the System Information produces: Battery Information: Charge Information: Charge Remaining (mAh): 0Fully Charged: NoCharging: NoFull Charge Capacity (mAh): 0 Health Information: Cycle Count: 0Battery Installed: NoAmperage (mA): 0Voltage (mV): 0 SMC and PRAM resets have done nothing. Does anyone have any experience in whether this is likely to be a battery or a logic board issue? The battery was replaced in May with a third party battery. Is there another test I can do other than buying another battery? Thanks, Sam
The micro controller within the battery is not responding! Which is why the system is not seeing it. Sorry, you’ll need to replace the battery. Given the age of the system it’s likely well worn as well.
