The mainboard is held in place by the marked locking tang. Using your fingers, push the locking tang away from the mainboard. If you cannot push with your fingers, a plastic spudger can be used instead.

Do not lift the mainboard past the perpendicular position. Permanent damage to the connected data cable may occur if the mainboard is pushed or pulled too far.

While holding the locking tang back, lift the mainboard to the perpendicular position.
