    • Use a spudger or a clean fingernail to flip up the locking flap on the daughterboard ZIF connector—this is the unlocked position.

    • Use the widest tool possible to avoid damaging the delicate hinge pins.

    • Once the flap is in the unlocked position, use tweezers or your fingers to gently pull the cable out of its socket by the blue tab.

    • To reconnect, make sure the locking flap is flipped up and gently reinsert the cable. Then, flip the locking flap down to secure the cable. The cable should slide into the socket with little to no force. If you're having trouble, remove it, check that the flap is fully unlocked, and try again.

    • Remove the daughterboard from the laptop.

To reassemble your device, follow these instructions in reverse order.
