My MacBook Pro 17”, mid 2010 model is not charging. I’ve switched out 2 batteries. I’ve tried multiple mag safe power supplies. The Mag safe light is green. I’ve pzapped the ram and SMC My Mac repair guy thinks it’s a logic board issue and wants to charge me $250/hr to start looking around. Any suggestions? Update (06/07/2018)
Lets get a better handle on the batteries. Download this great app: CoconutBattery depending on your OS you may need to older version. Lets see what is says. Post a screen shot of the main window here for us to see: Adding images to an existing question. Do one with the charger plugged in and a second with the battery. As you have a few batteries do them as well hopefully you’ve ID’ed them so we can tell which is which.
