Hello guys, So after reading a lot about the topic I still have issues with my macbook pro. So long story short, at time ‘‘A’’ I replaced the megsafe cord with one i bought . Never thought worked 100% because the light not always work and sometimes i connect to mac and it doesn t charge. At time ‘‘B’’ original macbook pro battery died and mac only works connected to cable cord. At time ‘‘C’’ with new battery I’m suffering random shutdowns. Already calibrate battery and reseted SMC various times. Can anyone help me? PS: I was thinking buying a new megsafe charger but I dont know if the problem is the new battery or logic board and I didn t want to spend 80€ for nothing image with charger light off

Repairing mag-safe adapters can be difficult and easy to mess up. I would start by replace the adapter with an Apple original. Most of the time used ones are OK. But the ones you get from iFixit carry a lifetime warranty. Apple MagSafe 1 AC Adapter
