keyboard cable to the same connector.

that was replaced, you might need to confirm the updated information in the Setup
Utility program. Refer to “Starting the Setup Utility” in the Hardware Maintenance
Manual.
To complete the part installation:

or loose screws are left inside your computer. Refer to “Locating components”,
