The screws we need to remove all supposedly share the same pictogram imprinted on the bottom case. If this is true why have you circled the rightmost screw in the photo above? The forth pictogram is near the screw below and to the left of the circled screw?

Assuming Mike Kearney’s pictogram tip is correct we have a problem with this tutorial. Specifically, there’s a problem with the red circles identifying the four screws to remove in Step three. The right-most screw circled in this tutorial does not share this pictogram? The screw below and slightly to the left of the one circled has the pictogram. Which screw on the right side of the computer shall we remove?

Where in this guide does it say how much RAM is supported? Am I missing something? Looks like two slots?

The back case will still be attached to the motherboard here because the two speaker wires are still connected. You made no mention of removing the speaker wires? These connectors are small and stubborn while removing.

Be careful when removing adhesive from the back of the reused display. There’s black film beneath the adhesive which can tear and pull up itself.

I labeled mine with label printer labels prior to disconnection. The label/tabs made reinstalling easier as I held onto the label/tabs while pressing down on the connectors. Much easier than holding onto the physical wires.

Great technique. I plugged a cable into every port before tightening logic board screws.

As seen in the photo this clip clearly has a pull tab. Forget the spudger and just open the clip with the pull tab.

The photo you added is of the wrong side of the power cable connector? Please add a photo of the rear facing side so the clip mechanism so disconnection can be clearly understood.
