The main board is also held in with two screws - go ahead and remove them.

You may need to slide the Bluetooth antenna’s sheath out of the way of one of the screws.

Again, keep track of your screws! These are a different length than the case screws.

Once the screws are out, pull the board directly up.

Everything is connected through some pin headers, so don’t worry about disconnecting any ribbon cables.

If one of the cables tries to come up with the mainboard, just pull it off and return it to its place.
