6 517212-001 — Removing and Replacing the Hard Disk Drive
15 Remove the two hard drive retention screws. Set them
aside for use with the new hard drive.
16 Slide the hard drive to the rear of the computer until it
stops. Then slide the hard drive toward the center of
the computer to release it.
17 Lift the hard drive straight up and out.
18 Press the release button on the end of the power cable
and the data cable while disconnecting these cables
from the drive.
CAUTION: Using retention screws that are
too long can damage some hard disk
drives. The hard disk drive retention screws
are slightly shorter than the rest of the
screws. Set these screws aside for use with
the replacement hard disk drive.
