incredibly difficult. easy times unscrewing things but no guide as to "disconnecting.. cables..". used a jewelers loop & a flash light to see "push" on the connector, but that's it. Push down to connect? ..or up to disconnect.. slide it out- squeeze the something. nothing. I ended up breaking it off the logic board accidentally, rendering my computer irreparable, unless i could solder the wires to the board. yeah right. My advise do do it.
