Completing the FRU replacement
After replacing the FRUs, you need to install any removed parts, reinstall the
computer cover, and reconnect any cables, including telephone lines and power
cords. Depending on the FRU that was replaced, you might need to confirm the
updated information in the Setup Utility program, see Chapter 6, “Using the Setup
Utility,” on page 49.
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.
To reinstall the computer cover and connect cables to your computer:
1.
Ensure that all components have been reassembled correctly and that no tools
or loose screws are left inside your computer. See “Locating components” on
page 88 for the location of various components.
