Completing the parts replacement

CAUTION:
After replacing a CRU, reinstall all protective covers, including the computer cover, before connecting
power and operating the computer. This action is important to help prevent unexpected electrical
shock and help ensure the containment of an unexpected fire that could happen under extremely rare
conditions.
After completing the installation or replacement for all parts, reinstall the computer cover and reconnect
cables. Depending on the parts you installed or replaced, you might need to confirm the updated information
in the Setup Utility program. Refer to "Using the Setup Utility program" on page 69.
To reinstall the computer cover and reconnect cables to your computer, do the following:
1. Ensure that all components have been reassembled correctly and that no tools or loose screws are left
inside your computer. See "Computer components" on page 35 for the locations of various components
in your computer.
2. Ensure that the cables are routed correctly before reinstalling the computer cover. Keep cables clear of
the hinges and sides of the computer chassis to avoid interference with reinstalling the computer cover.
3. Hold the computer cover with the handle and position the computer cover on the chassis. Insert the tabs
on the bottom of the cover into the corresponding slots on the chassis.
