Laptop shuts off when I unplug the charger
I have a MacBook Pro 13” Mid 2012. It first began shutting off at 50% if the charger wasn’t plugged in, so I’ve just been keeping it in for this reason.
I recently unplugged it so I can bring my laptop with me on a trip, tried to plug it back in and turn it on once I got to my destination and it wouldn’t turn back on. There was only a very dim, flashing orange light appearing on the charger.
I opened up the back and disconnected the battery connector on the motherboard, plugged it back in, and now the charger light is green and laptop turns back on. NOW, my laptop has stayed on 96% and shuts off whenever I unplug the charger.
I attached some photos of the System Report and Coconut Battery Health App. I tried doing an SMC reset by holding Shift + Cntrl + Opt and power button for 10 seconds, but I don’t think it worked.
Any suggestions on how I should move forward would be greatly appreciated!
