Installing the Top Cover
1. Before replacing the top cover, make sure no tools or
loose parts have been left inside the system chassis.

their respective slots and that all interior cables are
properly connected.

outside the chassis metal.

until it stops at the edge of the front bezels.
5. Reinstall two retaining screws at the back.
6. Reinstall the two side panels.
