My Mac book pro not charge even charger is ok. Charger light blink green for 2 to 3 sec and after that red light blink for 2 to 3 sec and then light stop blinking.
Hi have you tried cleaning the contacts for the MacBooks charging port with some isopropyl alcohol as they can get very dirty over time you can use cotton buds/qtips or a soft toothbrush to do this if this doesn’t work let me know Hopefully this helps Any questions please ask Thanks:-)
What is the condition of the MagSafe charger? Is the cord in good shape? No cuts or other damage. See if cleaning the contacts helps. Is this the original battery or a newer one (one or two years old) A dim green MagSafe charger LED is not a good sign, it often tells me the charging MOSFETs are damaged on the main logic board.
