WARNING: For Parallel ATA drives, connect the IDE cable end (C) labeled Master to the primary hard disk drive. If the IDE cable is not connected correctly, the PC will not be able to locate the hard disk drives and data may be lost.
Adding an Additional Hard Disk Drive You can add an additional or secondary Serial ATA hard disk drive to the bottom of your PC (select models only). Check the bottom of your PC for four mounting holes to attach the secondary hard disk drive. If your PC has the holes, continue with this procedure. If your PC does not have the holes, you cannot add an additional hard disk drive.
4 Align the hard disk drive with the holes on the bottom of the PC. The cable connectors must face the back of the PC. Insert and tighten the four screws. 5 Attach the data and power supply cables to the back of the hard disk drive. Serial ATA hard disk drive Parallel ATA hard disk drive WARNING: For Serial ATA hard disk drives, do not use right angle data and power cable connectors. Right angle connectors will bend against the chassis bottom, and may break.
6 Attach the data cable connector end to an open Serial ATA (or Parallel ATA) connector on the PC motherboard. Serial ATA motherboard connector WARNING: Do not to use the connector that was connected to the original Serial ATA drive that was installed in the system. 7 Complete the procedures to replace the side panel, and to close the PC.

Installing a Memory Module Upgrade the memory in your PC with memory of the same type and speed as the memory originally installed in your PC. CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. 1 Open both latches of the memory module socket. See “Removing a Memory Module” on page 11. • If you are replacing a memory module, put the new memory module in the same memory slot from which the old memory was removed.
Removing an Add-in Card 1 Complete the procedures to prepare the PC and remove the side panel as described in “Opening and Closing the PC” on page 1. 2 Gently lay the PC on its side. 3 Inside the PC, locate the add-in card slots on the motherboard. 4 If you are replacing a card, make a note of any external or internal cables attached to the card, and then disconnect them. 5 Loosen the screw on the card you are replacing.
Replacing the Battery A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability. When the battery starts to weaken, the date and time may be incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery. WARNING: There is danger of explosion if the battery is incorrectly replaced. Replace only with the same, or equivalent, type of battery. Discard used batteries according to the manufacturer’s instructions.
