Hi people, My wife’s trusted MBP won’t turn on. The first clue is that the Magsafe indicator does not turn green when plugged. I have tried with another Magsafe charger, borrowed from a friend, but the result is the same, no green light at all. The second clue is linked to the charging indicator (on the side of the laptop): its first led blinks green rapidly when the Magsafe is plugged (upon pressing the button), but won’t turn on when the Magsafe is not connected. Any clues? Thanks in advance for any input, and I apologize if this question has been asked before (I have searched the similar questions but found none with the exact same conditions).
I assume the MagSafe plug stays Amber even after leaving it charging for 8 hrs. If thats the case you need a new battery: MacBook Pro 15" Unibody (Mid 2009-Mid 2010) Battery and here’s the guide you’ll need to follow: MacBook Pro 15" Unibody Mid 2010 Battery Replacement Update (06/08/2019) Stephane - Well, that puts a wrinkle in the answer! While you likely need a new battery, that’s not your issue here. No MagSafe LED is telling me either the MagSafe connector (DC-In board) or the charging logic has issues.
