if you removed the support bracket, reinstall it before you replace the side cover.
see “removing and installing the support bracket” on page 33.
the rear adapter retaining bracket rests against the computer side cover.
you might find it easier to lay the computer on its side to replace the side cover.
complete the following steps to replace the side cover:
1. before installing the cover, check that all cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the computer.
2. place the bottom lip of the side cover over the bottom edge of the computer chassis.
3. rotate the side cover to a vertical position, inserting the tabs at the top of the side cover into the matching slots in the computer chassis.
4. slide the side cover forward until it locks in place. press down on the cover-release-latch button as you close the cover-release latch to lock the side cover.

5. if you have not done so already, make sure that the two front stabilizing feet are rotated outward so that they properly support the computer. rotate each foot outward 90 degrees (see “moving the stabilizing feet” on page 30).
6. reconnect the external cables and power cords to the computer; then, connect the power cords to electrical outlets.
7. turn on the attached devices; then, turn on the computer.
