Chosen Solution
I have a MacBook Pro (Retina, 15 inches, Mid 2012), recently replaced the battery ourselves with an ifixit kit (MacBook Pro 15" Retina (Mid 2012-Early 2013) Battery, Fix Kit. SKU: EU117047-5). This was fitted at the beginning of February and had given the mac a new lease of life. But unfortunately, it was being used last week it ran out of charge even though the MagSafe charger had a green light on it, it ran out of power. I have since tried another power supply that has the same green light on, and also not charging. I have tried resetting the SMC but nothing seems to work or power it up. If I press the power button the no charge icon appears on the screen and the MagSafe light stays green. Has anyone any ideas? could it be the logic board or is there anything else that can try?
