Completing the parts replacement
After completing the installation or replacement for all parts, you need to reinstall the computer cover and
reconnect cables. Depending on the parts you installed or replaced, you might need to conrm the updated
information in the Setup Utility program. Refer to Chapter 6 “Using the Setup Utility program” on page 37
.
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 “Locating major FRUs and CRUs” on page 56
for the locations of various
components in your computer.
2. If you have removed the front bezel, reinstall it.
3. 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.
4. Align the cover with the chassis, and then close the cover to engage the cover latch. Use the keys
attached at the rear of your computer to lock the keylock that is built into the computer cover.
5. If there is a padlock available, lock the computer cover.
6. If there is an integrated cable lock available, lock the computer..
7. Reconnect the external cables and power cords to the computer. See “Locating connectors on the
rear of your computer” on page 56.
8. To update your conguration, refer to Chapter 6 “Using the Setup Utility program” on page 37.
Note: In most areas of the world, Lenovo requires the return of the defective Customer Replaceable Unit
