after closing the pc replacing the side panel To avoid injury and equipment damage, always follow this procedure in this order after closing the PC. 1 Place the side panel in the proper position on the chassis and slide it into place. 1 Reconnect the power cord. WARNING: To reduce the risk of electrical shock, fire, or damage to the equipment, do not plug telecommunications or telephone connectors into the network interface card (NIC) (labeled as an Ethernet connector).
replacing the front panel 1 Align the top of the front panel with the top of the chassis front. 2 Press the panel onto the chassis at the top and at each side near the bottom until the panel snaps into place. removing and replacing drives Your PC has several drives that you can replace or upgrade. See the preceding topic, “locating components inside the PC“ for drive type and location.
3 Release the drive from the chassis by lifting the tab (1) on the latch drive bracket, and then sliding (2) the drive partway out of the bay. (The latch drive bracket secures the drives in their respective positions in the chassis.) 4 Disconnect the power cable (1) and data cable (2) from the back of the drive you want to remove, as indicated in the following illustrations. Use a gentle rocking motion. Some units may have a sound cable. If so, disconnect the sound cable (3).

Your drive may vary from the illustration. cable select jumper NOTE: An optical drive may include a sound cable. Connect this cable also. connecting the memory card reader drive cable 4 Install four guide screws on the sides of the new drive (two on each side). The screws help guide the drive into its proper position in the bay.

The PC ships with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity ones. 5 Push down the two retaining clips on the ends of the memory socket until the memory module pops out of the socket. The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules).
2 The memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket (B). Push the module carefully and firmly into the slot, ensuring that the latches on both ends snap into place. removing an add-in card 1 Complete the procedures to prepare the PC and to remove the side panel. See “opening and closing the pc“ on page 1. 2 Gently lay the PC on its side.

The whole connector should be seated properly in the card slot. replacing the battery A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability.
