Remove the 4.8 mm standoff screw near the headphone jack.

Standoff screws are best removed using a standoff screwdriver or bit.

In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

When reassembling the device, this standoff sets the height of the Wi-Fi shield removed in step 13. If not torqued down, the shield will be above the plane of the frame and the back will not slide into place in step 2. The shield should be flush with the headphone jack.

When reassembling the motherboard, ensure that its edge sits under the circled standoff, otherwise the screws will not fit.

When reassembling ensure that the small rubber spacer attached to the top of the motherboard is in place.

Without this part, the motherboard could damage the ribbon cables around it.
