This section provides instructions on how to access the system board components and drives.
To access the system board components and drives:
1. Open the computer cover. See “Opening the computer cover” on page 107.
2. On some models, you might need to pivot the drive bay assembly upward and remove the hard disk
drive to access the internal components. See “Replacing the hard disk drive” on page 122.
Note: Make sure you note the location of any cables that you disconnect from the drives or the system
board.
Attention: If your computer has an internal hard disk drive, you must return the hard disk drive to the
latched position before closing the computer cover to prevent damage to the hard disk drive.
