WARNING: Please read "Safety Information" in the User's Guide before installing and connecting your system to the electrical power system. · Write down and save the system model and serial numbers, all installed options, and other information about the system. It will be easier to consult this information than to open up and examine the PC. · Compaq recommends that you use an antistatic wrist strap and a conductive foam pad when working on the system. WARNING: Always disconnect the modem cord from the telephone system, and then disconnect the PC from the power source before removing the front and side panels of the PC. Failure to do so before you open the PC, or do any procedures, can result in personal injury or equipment damage. Opening and Closing the PC Before Opening the PC 1 Remove any diskette or optical disc (CD or DVD) from the PC. 2 Click the Start button, and then click Turn Off Computer. Click Turn Off. 3 Disconnect the modem/telephone cable, if present. CAUTION: To reduce the risk of personal injury from electrical shock or hot surfaces, disconnect the power cable from the wall outlet, and allow the internal system components to cool before touching. Preparing the PC Before you upgrade any component in your PC, you need to prepare the PC so that you can safely handle it and the components. Read the following items before attempting to upgrade or service the PC. · These procedures assume familiarity with the general terminology associated with personal computers, and with the safety practices and regulatory compliance required for using and modifying electronic equipment. 4 Disconnect the power cable from the electrical outlet and then from the PC. 5 Disconnect all other attached cables (such as the keyboard, mouse and monitor) and all external devices. CAUTION: Static electricity can damage the electronic components of the PC or optional equipment. Ensure that you are discharged of static electricity by briefly touching a grounded metal object. Upgrading and Servicing Guide 1 After Closing the PC To avoid injury and equipment damage, always follow this procedure in this order after closing the PC. 1 Reconnect the power cable. 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 Side Panel 1 Place the side panel in the proper position on the chassis, and slide it into place. 2 Reconnect the modem/telephone cable, and all other cables (such as the keyboard, mouse, and monitor) and external devices. 3 Turn on the PC and all peripherals. 4 If you installed an add-in card, install any software drivers supplied by the card manufacturer. Removing the Side Panel 1 Remove the side panel by loosening the screw (D) that secures the panel to the PC chassis. 2 Ensure that the hole for the thumbscrew aligns with the hole in the chassis, and replace the thumbscrew (D). Removing the Front Panel This procedure is necessary only when removing or replacing an optical drive, memory card reader, diskette drive or the hard disk drive. 1 Press and hold down the square button (1) near the top front of the inside of the chassis. Press one tab (2), and then press the other tab (3), toward the outside edge of the chassis. 2 Slide the panel back about 1 inch (2.5 cm), and then lift it off the unit. WARNING: Beware of sharp edges inside the chassis. 2 Remove the front panel. 2 Upgrading and Servicing Guide 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. The hard disk drive is either a Serial ATA (advanced technology attachment) drive that uses a narrow data cable, or a Parallel ATA drive that uses a wide data cable. CAUTION: Back up your personal files on the hard disk drive to an external storage device, such as a CD, before removing the hard disk drive. Failure to do so will result in data loss. After replacing the hard disk drive, you need to run System Recovery, using the recovery discs, to load the factory-installed files. See the user documentation that came with your PC for details about the recovery procedure. Locating Components Inside the PC You can add an optical drive into an empty lower optical drive bay. IMPORTANT: Before adding a new optical drive, make sure that it is compatible with the Microsoft® Windows® XP operating system. Also, make sure you have the correct software and drivers for the optical drive to work with the operating system. Removing a Drive A Upper optical drive bay, may be a CD-ROM, CD-RW, DVD-ROM, DVD+RW/+R or combination drive B Lower optical drive bay, may be empty (blank plate) or a CD-ROM, CD-RW, DVD-ROM, DVD+RW/+R or combination drive C Memory card reader (select models) D Diskette (floppy) drive (select models) E Front connector panel (no replacement instructions) F Hard disk drive 1 Complete the procedures to prepare the PC, to remove the side panel, and to remove the front panel. See "Opening and Closing the PC" on page 1. Upgrading and Servicing Guide 3 2 Locate the drive you want to remove. Disconnecting the Memory Card Reader Drive Cable 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 and data cable from the back of the drive you want to remove, as indicated in the following illustrations: · For optical drives, disconnect the power cable (P) and the data cable (D) from the back of the drive you want to remove. If the drive has a sound cable (S), disconnect it also. · For most drive cables, use a gentle rocking motion to free the plug. For Serial ATA hard disk drive cables, press the latch (1) (select models only) in the center of each plug and pull the plug (2) from the drive connector. Disconnecting the Diskette (Floppy) Drive Cables Disconnecting the Serial ATA Hard Disk Drive Cables Disconnecting the Optical Drive Cables Disconnecting the Parallel ATA Hard Disk Drive Cables 4 Upgrading and Servicing Guide 5 Pull the drive out of the drive bay. 6 If you are replacing the old drive with a new drive, remove the four guide screws (two on each side) from the old drive. You need these screws to install the new drive. 5 Slide the drive partway into the drive bay, making sure to align the guide screws with the guide slots. Replacing or Adding a Drive 1 If necessary, remove the existing drive. See "Removing a Drive" on page 3. 2 If you are adding a drive to an empty lower optical drive bay, you must remove the blank plate from the bay. To do so, insert a flat screwdriver into the blank plate slot (C) and rotate the screwdriver to break the blank plate out of the chassis. Discard the blank plate. 6 Reconnect the power and data cables to your drive, as indicated in the following illustrations. If it is present, reconnect the sound cable. 3 Make sure the jumper on the new optical drive or new Parallel ATA hard disk drive is in the CS (Cable Select) position. Your drive may vary from the illustration. The Serial ATA hard disk drive does not use cable select. Connecting the Optical Drive Cables NOTE: An optical drive may include a sound cable. Connect this cable also. Cable Select Jumper 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. Connecting the Memory Card Reader Drive Cable Upgrading and Servicing Guide 5 Adding Memory Your PC comes with random access memory (RAM), which temporarily stores data and instructions on your PC. The PC ships with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity ones. The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). The exact number of sockets and type of DDR memory module depends on which model PC you have. Connecting the Diskette (Floppy) Drive Cables A DDR DIMM To determine which type of memory module your PC uses, and for specific memory module information and specifications, go to the Web site listed in your Warranty and Support Guide and click the Support link. Connecting the Serial ATA Hard Disk Drive Cables WARNING: Using the wrong type of memory module could damage the system. Removing a Memory Module 1 Complete the procedures to pr ...
