The new panel will have some protective plastic over the screen. It's a good idea to leave this on until just before the bezel goes on.

Place the new panel in the same orientation as the old panel, face-down, on the keyboard. Reconnect the plug and secure with the existing tape (if it's in good enough shape), or a new piece.

Before lifting up the panel and securing with screws, make sure that the tape holding the protective plastic is out of the way.

To reassemble, just follow the guide in reverse order. Remember to remove the protective plastic sheet from the new panel before snapping the bezel back on.
