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.

Reconnect the external cables and power cords to the computer. See “Rear
connectors” on page 128.

“Flash update procedures” on page 606.
