Macbook comes in. Does boot, but green light on charger.

I disconnect battery, and try with just charger no luck.

I investigated the other side of the board and found corrosion on U7840 which I removed.

Success! Computer now boots with battery and charger connected. BUT the keyboard does not work (I have to disconnect both charger and battery then reconnect to get a boot)

and the Caps Light on Keyboard is always on.

Simple case of keyboard replacement or trouble ahead?

You should try first known good TP/KB; remember, KB will not work if TP doesn't.

Battery is recognized by macOS at least?
Check its SCL/SDA lines.
