Rather than show all of these comparisons, how about showing every single step, every little insignificant piece of whatever that you remove, move to take something out or to make taking something out easier... I've got the MackBookPro 17" back together and have about a half dozen parts that go somewhere, but who knows.
How about putting some arrows pointing out connectors that are being removed??? Not just listing 6-7 of them and assume we know what it is and more importantly where it is...
Good evening. Should the mains plug be disconnected before disconnecting the battery? Joseph Deneurone - Feb 14, 2018 Hello, yes, it is indeed recommended to completely unplug the computer from the outlet and the AC adapter. It's best to wait for the battery to discharge. You will thus avoid any risk of short circuit when handling the computer. Good repair! Claire Miesch - Feb 15, 2018
