Restoring the factory contents by using Recovery Disc Set
When the hard disk drive or solid state drive is replaced because of a failure, no product recovery program
is on the new hard disk. In this case, you must use the Recovery Disc Set for the computer. Order the
Recovery Disc Set and the hard disk drive at the same time so that you can recover the new hard disk drive
with the pre-installed software when they arrive. For information on which discs to order, see “Recovery
discs” on page 156
.
The recovery disc set consists of the user instructions and the following set of DVDs to restore the computer
to the original factory conguration.

This disc restores the Microsoft
®
Windows operating system. Use this disc to start the recovery process.
Applications and Drivers Recovery Disc (one or more discs)
This disc restores the preinstalled applications and drivers on the computer.
Supplemental Recovery Disc
This disc contains additional content, such as updates to the software that was preinstalled on the computer. Not
all recovery disc sets come with a Supplemental Recovery Disc.
Notes:
You must have a DVD drive to use the recovery discs. If you do not have an internal DVD drive, you
