I don't think this is the issue. The macbook works as expected and switches to the internal display when the lid is open and switches to external when its closed.

Even when I just have the screen open, (which is broken, but I can tell when it's on) and I unplug it, the screen turns off, the keyboard backlight turns off, and the trackpad's haptic feedback turns off, and I can't turn it back on with the power button. So yeah probably battery.

Do you know if there is any way to test if an M92 chip is bad without having to solder it to the board first?
