Accessing system board components and drives
To access system board components and the drives:
1. Open the computer cover. See “Opening the cover” on page 12.
2. On some models, you might need to pivot the drive-bay assembly upward and
pivot the hard disk drive upward to access the internal components, see
Figure 6.
Note: Make sure you note the location of any cables that you disconnect from
the drives or the system board.
Attention: You must return the hard disk drive assembly to the latched
position before you close the cover to prevent damage to the hard disk drive
assembly.
