步骤 3

Use a spudger to pry up each side. Then, lift the connector straight up from its socket.
To reinstall, carefully position the connector, and then press it straight down until it snaps into its socket. Finger pressure is all that is required. If it won't snap home it'll be because it isn't correctly positioned. Sometimes it can take a little patience to find exactly the right position.
