Computer dies on battery power
I just installed the a second replacement battery in my MacBook Pro.
After fully charging the battery and disconnecting the power adapter, the MacBook just dies after taxing the computer a little bit like scrolling through pictures in Aperture of Photos.
The computer has recently undergone a major repair after sitting in a drawer for over a year. I removed the mother board and applied heat to the GPU and CPU, reassembled the computer and it booted. The original battery, however, would not take a charge.
I’m wondering if I would have better luck with a better battery or could there be another problem with the computer?
The battery I installed is a relatively cheap after market battery manufactured by Cameron Sino. Will I have better luck with a Ifixit battery?
Update (04/12/2019)
I just removed the magsafe charger and went to markup a photo I took of the motherboard. During this process the computer died.
In the photo of the motherboard the component with a red rectangle fell off while I heated with a heat gun. I got it back on with the heat gun. I am wondering if this could be the problem. I am not sure what the component does. I used a thermometer and kept the temperature under 230 degrees celsius. Another issue I had after initially putting the computer back together was the wires to the magsafe female end in the computer got squeezed and the computer was not getting power. I discovered this issue loosened the screw and freed the wires and it booted but the 8 year old battery that hadn’t been used in over a year would not charge. I do not know how to read schematics and board views. I do not have any tools for working on logic boards.
How will I see if the battery is delivering enough power?
Es esta una buena pregunta?

The component is an inductor coil L8920 0.56UH-31A. Its part of the PPVCORE_GPU powering GFXIMVP6_PHASE line on U8900

@danj Right, not at all related to the charging circuit that will have to be troubleshooted separately. It takes quite a bit of heat to get that big coil off the board, very lucky thing that everything still works around Cpu/Gpu :)
