Replacing A Hard Disk Drive - Lenovo ThinkCentre A55 Hardware Maintenance Manual

Replacing a hard disk drive

Important
When you install a new hard disk drive, you also need a set of Product
Recovery discs. The set of Product Recovery discs will enable the contents of the
hard disk to be restored to the same state as when the computer was
originally shipped from the factory. For more information on recovering
factory-installed software, refer to "Recovering software" in the User Guide.
1. Open the computer cover. See "Opening the cover" on page 83.
2. Pivot the drive bay assembly upward to gain access to the system board.
3. If an optical drive is installed, disconnect the signal cable from the drive to
access the hard disk drive cables.
4. Disconnect the signal and power cables from the rear of the hard disk drive.
