Actually, that is exactly what the mag-safe adapter does when it charges a battery. It is green when first plugged in, then if it needs it it starts charging the battery and changes to orange. Lets see if it will sententiously boot. Disconnect the battery from the logic board, also the mag-safe. Press and hold the power on button for ten seconds. Now plug in the battery then the mag-safe. It should reboot.
