    These (and Dell’s) instructions don’t mention that you have to disconnect a second keyboard cable. It’s a 4 pin ZIF connector, you can see it in the picture above, already disconnected.

    • Pry up the right side of the palm rest.

    There are a couple of latches on the front of the palm rest which should be released before you move on to the sides. I think one of those latches is released in the picture above. The iFixit opening tool was helpful here, and I used some of the iFixit opening picks to stop the corner latches from closing while I worked on others.

    You can skip this step, and others related to removing the display, because removing the display isn’t strictly necessary.

    Con of removing the display:

    o It takes time

    Pros of removing the display:

    o It makes it a little easier to remove the VGA card

    o The computer will tip with the weight of the display when you remove other components.

    Indeed, pull straight up using the integrated handle on the connector. It required more force than I expected, and popped off suddenly once I pulled hard enough.

    If you decided to leave the display in place, you can just loosen the screw on the VGA board, and leave the board itself where it is. The board blocks access to a screw securing the system fan, but once you’ve removed the screw from the VGA board you can just push the VGA board out of the way and remove the system fan screw. Of course, this means the VGA board can move around while you’re working on the rest of the computer, but I didn’t find that was a big problem. You could temporarily reinstall the VGA board screw after you’ve removed the system fan.
