MacBook Pro not working without charger
My MacBook Pro doesn’t boot without the charger. It even turns off if the charger is disconnected. Coconut battery says cycles completed are 3. But battery status is poor and battery failure says yes.
I tried doing an SMC reset but I don’t know if it’s working as the battery is at full capacity.
When it’s plugged in and I press the battery status button, it blinks 5 times with all lights. When it’s not plugged in, battery indicator doesn’t work.
Even the front light blinks 5 times, then stops, then again blinks 5 times when I boot up the MacBook, again while connected to the 85W charger.
I had replaced the old battery with a new one as it had swollen up.
For reference, I had kept this MacBook unused for over a year with this new battery which was working fine before.
Is this just a bad battery? Or is it my charger? Or worse, my MacBook?
It doesn’t seem like a battery problem because it is brand new.
Is dit een goede vraag?
