Battery taking a long time to charge
I have a MBP early 2011, I have replaced the battery with a genuine apple one. it takes over 12 hours to charge, and only runs for less than 2 hours on battery once charged. So here is what i’ve tried.
- Ran battery calibration 3 times as on apple website
- SMC reset
- PRam reset
- multiple genuine apple 85watt chargers
- new hard drive with fresh install mac OS (to eliminate any OS settings or software)
I have tried the new battery in another macbook pro early 2011 of exact spec. it charges to full in 2.5 - 4 hours hours with over 5 hours running time on battery. So clearly the battery is not at fault.
So it looks to be a hardware fault, i have ordered the internal magsafe PCB. which I am waiting to arrive. Anyone else have ideas. its starting to look like logic board.
I am an electronic engineer by trade and quite capable of any hardware replacement on this device.
Is this a good question?
