See “Opening and Closing the Computer” on page 1.
3 Disconnect the power and data cables from the back of the drive. 4 Pull the drive out through the front of the chassis. Adding or Replacing the Primary Hard Disk Drive 1 If you are replacing the existing hard disk drive, remove it. See “Removing the Primary Hard Disk Drive” on page 10. 2 Slide the hard disk drive partway into the front of the chassis.
3 Connect the power and data cables to the back of the hard disk drive. A — Connect to a primary hard disk drive. B — Connect to a secondary hard disk drive (select models only). C — Connect to the motherboard. 4 Slide the hard disk drive completely into the front of the chassis. 5 Align the two screw holes on the chassis with the two screw holes on the side of the drive labeled HDD, and then attach the two screws. 6 Replace the front and side panels, and then close the computer.
Removing the Memory Card Reader 1 Prepare the computer to be opened, and then remove the side and front panels. See “Opening and Closing the Computer” on page 1. 2 Release the memory card reader by removing the screw on the right side of the memory card reader, sliding the reader to the left to loosen it, and then pulling it partway out through the front of the chassis.
Adding or Replacing a Memory Card Reader 1 If you are replacing an existing memory card reader, remove it. See “Removing the Memory Card Reader” on page 13. 2 If necessary, remove the knockout plate on the front cover. To do this, press the release button (A), and then pull the plate out.

For Serial ATA hard disk drive cables, press the latch (1) (select models only) in the center of each connector (2), and then pull the connector out of the drive connector.
Adding Memory Your computer comes with random access memory (RAM), which temporarily stores data and instructions on your computer. The computer is shipped with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity modules. The motherboard contains sockets for DDR (double data rate) DIMMs (dual in-line memory modules). The exact number of sockets and the type of DDR memory module depend on the model of computer that you have.
5 Push down the two retaining clips on the ends of the memory socket until the memory module pops out of the socket. WARNING: Do not pull the memory module out of the memory socket. Always use the retaining clips to remove the module. 6 Lift the memory module out of the memory socket.
