MacBook Pro not charging after running out of battery

텍스트:

Hi,

I posted this question a few months ago and managed to resolve it myself by changing the DC in board, but today the same issue happened. Laptop ran out of charge and doesn’t charge when plugged in or start up. The DC in board is only a month old and looks fine visually. I also took apart the computer to make sure the connections were secure and clean and they are. The charger blinks green three times over ten seconds when I plug it in and the indicator light shows that it has no charge. My battery was tested last week in coconut battery and has 86% health so it’s still okay. I’m at wits end as the laptop was working fine before I ran out of battery.

Original question: “I’ve had my mid-2012 15 inch unibody Macbook Pro since 2012 and it’s been a champ, withstanding daily use of up to 7+ hours. Only issue I ever had with it was a wifi ribbon that needed replacing a year ago. Yesterday night, I was busy working and lost track of the charge and it died. Plugged it into my charger, but the charger light wouldn’t come on and there was no evidence that it was charging. Not to worry, I had another charger and tried with a different outlet. This charger’s light blinked green three times before going dark again. Still nothing. I unscrewed the bottom and disconnected the battery before trying to plug it in and power it on, but still nothing. I’ve run the laptop before with the battery cable out so this gave me pause. My concern now is that its either an issue with the magsafe port or the logic board, and I’m praying its not the latter as I leave for an overseas trip in two days and need my laptop to do work there. As a result of the battery being drained, I can’t do an SMC or PRAM reset and can’t run any diagnostics. Any advice would be appreciated.”
