I took a couple of the ones with the green bases and found that I can peel the green base off of the black part. After doing that I found that the green base has gold colored foils that I can peel off pretty easily with a chisel. Plus, there were some that had a metal disc on top of the black part.

I take my chisel with with the flat side down and put the tip between the green base and the board. Then I tap the chisel lightly with my hammer until it separated from the motherboard.

how do you remove those from the motherboard?

you can use a hot air desoldering machines, or if you are in the large number of boards, u can use a low temp torch to make it quick.
