MacBook Pro won't turn on after battery reach 1300 cycle

I have a 13” MacBook Pro late 2012, the battery has reached 1300 cc. Then the my system died suddenly. When I plug in the charger, my system turns on, I then notice that the battery says replace now.

Then bought a new original battery to replace the old one. It did not start the first time, and after a few hours after I had replaced the battery my MacBook turned on but the fan was in maximum speed and the battery was not recognized.

I then did SMC and NVRAM resets and it works, but after shutting down my system and then tried to turning it back on and it was successful and normal.

But now my system sometimes turning on but sometimes it won’t. Sometimes the MagSafe lights is on but sometimes not. The MagSafe charger is not genuine by the way.

Is there any chance that non genuine MagSafe causing the problem? And if I buy a genuine MagSafe, could it fix the problem?

Thank you

Well, you did it! You got 300 more cycles out of your battery was intended to run. Determine battery cycle count for Mac notebooks

Time to replace the battery! If you told us which model you had we could have even you a bit more.

Update (03/18/2020)

At this point you’ll need to decide which way to go. Your logic board has failed it might be repairable but you’ll need to find someone with the deeper skills to do that. Or, your other option is to replace the logic board:

@Oktavianus Misro Adrianto - Please tell us your exact model 13" or 15" as well as unibody or retina. Need that first otherwise I'm just shooting in the dark.

Install this gem of an app: CoconutBattery then take a snapshot of the main window so we can see what you have post it here Adding images to an existing question

it is 13" macbook Pro @danj. right now when I plug the charger in, it has green light but won't turn on. The macbook can't even turning on so there is no chance for me to take a snapshot. I already installed the coconutbattery yesterday, and the battery was recognized and it looks normal and good. after i turned off, the battery then unrecognized. Is it possible that the charger cause this problem? because the charger is not genuine.

While I strongly recommend using a real Apple MagSafe chargers as the cloned ones have damaged systems. OEM MagSafe Chargers vs Cheap Imposters: Teardown for Truth. I'm not sure that's the issue here alone. So yes, you really need to get the proper charger your system has issues as well.

okay @danj, Thanks for the information. I'm going to buy the original charger today and I'll give you the update soon

my macbook is on now but the battery is still unrecognized and the fan is in maximum seed
