Completing the FRU replacement

After replacing FRUs, you need to install any removed parts, replace the cover, and reconnect any cables,
including telephone lines and power cords. Also, depending on the FRU that is replaced, you might need to
confirm the updated information in the Setup Utility program.
Note: When the power cord is first plugged in, the computer might appear to turn on for a few seconds and
then turn off. This is a normal sequence to enable the computer to initialize.
1. Ensure that all components have been reassembled correctly and that no tools or loose screws are left
inside your computer.
2. Replace the cover.
3. Reconnect the external cables and power cords to the computer. See "Rear connectors" on page 107.

procedures" on page 285.

Utility" on page 39.
