First, tilt the entire bottom portion of the chromebook up in order to force both LCD hinges in an upward position. (Forcing the hinges in this position allows you more room to be able to lift out the motherboard and all of its components)

Then remove the motherboard starting by pulling the motherboard data cable up next to the fan. Keeping the fan, heatsink, and speakers attached to the motherboard saves you some time when installing onto the new palmrest.
