Motherboard or Battery problems?

I am trying to start repairing phones and one of my first is this moto E4 plus, when I plug it in nothing happens, when I hold down the power button nothing happens, no status LED’s, nothing. Could this be a problem with the motherboard or is it definitely the battery? my initial thought is the battery but I know that on some laptops they will show something even if there is no battery but it’s plugged in, do phones do this?
