General Information |
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.

The following tools are recommended for the Take Apart procedures:
•Coin
•ESD wriststrap and mat
•Magnetized #0 Phillips screwdriver
•Jeweler’s flat-blade screwdriver
•Small soft cloth
•Torx T8 screwdriver
•2.0 mm hex nut driver
•Needlenose pliers
•Torx T6 screwdriver
