4Replace the back panel of the computer.

Slip the back panel over the prongs at the bottom edge of the back of the computer, then push the back panel up and forward until it snaps into place. If the back panel was held on by security screws, reinsert them. (If your computer came with optional security screws, you can insert them now.)

WARNING Never turn on your computer unless all of its internal and external parts are in place. Operating the computer when it is open or missing parts can be dangerous, and can damage your computer.
