The touch pad assembly is held on by two slim plastic tabs, which have notches in them to keep this in place. CAREFULLY push up on the touch pad assembly to lift the notches out of the metal slots. Then slowly pull it away.
There are lots of wires inside, which prevent you from pulling it very far. This is where it is easy to break the slim plastic tabs. The touch pad will dangle from the wires, and the tabs can break if you let the weight press on them. It's better if you have two people. But one can do it if you are careful.
