Reassembly Notes
Position the speaker on the pins on the bottom case before you install the speaker cover.
If the slider came off the module latch, attach it to the latch before you install the speaker cover.
Hint
On the bottom case, the holes for the top case screws are unmarked. The hole recesses have flat
bottoms for the 16-mm T-head screws and tapered bottoms for the longer 19-mm flathead
screws.
