Note:
The metal EMI shields—bottom shield and top shield—are now marked with screw
identifiers for most of the screw locations. The screw identifiers are in the form of "M2x_"
where the last digit indicates the approximate screw length. For example, a marking of
"M2x3" indicates a 3.5-mm long screw, and a marking of "M2x14" indicates a 14.5-mm
long screw. Use the identifiers as a guide when reassembling the computer.
