2. Ground yourself by touching an unpainted metal surface at the back of the computer before touching anything inside your computer. While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components. 3. 4. Disconnect any devices connected to the computer, including the monitor, from their electrical outlets to reduce the potential for personal injury or shock.
Reattaching the Hinge Arms 1. Shut down the computer. 2. Disconnect the power cable from your computer. 3. Remove the front door, if it is attached. The front door snaps off of the two hinge arms. 4. Remove the front-panel insert above the front-door bay area. Pull the bottom of the insert with your fingers to remove it. 5. Lift both hinge arms to the horizontal position. 6. Use the two view slots to align the pivot bar with the two pivot-bar slots.
NOTICE: Using excessive force to pull the hinge arms into place may damage the arms or the front panel. 7. Pull the arms toward you until they snap into place. If the hinge arms don't snap back into place on the first attempt, slightly reposition the arms and try again. 8. After the hinge arms clip into place, lower and raise the arms two or three times to properly seat them. 9. Reattach the front-panel insert. 10. Reconnect the power cable to your computer. 11.
Adding Cards CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in "Safety Instructions." CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover. 1. Shut down the computer. 2. Turn off any attached devices and disconnect them from their electrical outlets. NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack. 3.
8. Lower the plastic securing lever. 9. Connect any cables that should be attached to the card. See the documentation that came with the card for information about the card cable connections. 10. Close the computer cover. 11. Connect your computer and devices to their electrical outlets, and turn them on. NOTICE: To connect a network cable, first plug the cable in to the network wall jack and then plug it in to the computer. 12.
HINT: Installing filler brackets over empty card- slot openings is necessary to maintain Federal Communications Commission (FCC) certification of the computer. The brackets also keep dust and dirt out of your computer. 8. If you are not replacing the card, install a filler bracket in the empty card-slot opening. If you are adding a card, see "Adding Cards." 9. Lower the securing lever. 10. Close the computer cover. 11. Connect your computer and devices to their electrical outlets, and turn them on.
8. Align the notches on the bottom of the module with the crossbars in the connector. NOTICE: To avoid breaking the memory module, do not press near the middle of the module. 9. Insert the module straight down into the connector, ensuring that it fits into the vertical guides at each end of the connector. Press firmly on the ends of the module until it snaps into place. During most installations, the securing clips snap into the cutouts at each end of the module.
NOTICE: Visually inspect the position of the securing clips on the memory connectors and make sure that they are secured in the vertical position in the cutouts on the ends of the memory modules. Otherwise, the securing clips may prevent the AGP card from being properly reinstalled. 6. To replace the AGP card, gently press it down into the slot connector until it clicks into place. Press the card clip lever while inserting the card into the slot connector. 7. Close the computer cover. 8.
NOTICE: Do not install any drive into the lower hard-drive bay until after you have removed the green drive rails from the inside of the hard-drive cage. 9. c. Gently slide the first hard drive into the lower bay until you hear a click. d. Reconnect the power cable and the data cable to the back of the first hard drive. Gently slide the new hard drive into the upper bay until you hear a click. NOTICE: Match the colored strip on the cable with pin 1 on the drive. 10.
Your computer includes a floppy drive and a CD or DVD drive. You can add other devices, such as a Zip drive, a CD-RW drive, or a tape drive. 5.25-Inch Devices CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in "Safety Instructions." 1. Shut down the computer. 2. Turn off any attached devices and disconnect them from their electrical outlets.
See the documentation that came with the drive for instructions on connecting a drive cable to the drive and system board. HINT: Your computer uses cable-select drive cables. This means that the device connected to the end connector of the drive cable is the master device and the device connected to the middle connector is the slave device. Be sure the jumper setting on the new device is set for "cable select" (see the documentation that came with the drive for information). 11.
9. Attach the rails to the drive using the screws supplied with the drive. Ensure that the rail tabs are positioned at the back of the drive. 10. Gently slide the drive into the bay until you hear a click. 11. Carefully replace the drive bay cover. You do not need to replace the cover insert. 12. Connect a power cable to the drive. See the documentation that came with the drive for instructions on connecting a drive cable to the drive. HINT: Your computer uses cable-select drive cables.
6. Disconnect the +12-VDC P2 DC power cable from the J4B1 connector on the system board. 7. Lift up the airflow shroud. 8. For each of the metal securing clips that secure the heat sink to the microprocessor, press down on the clip's latch to release the clip from the retention base. Then lift each clip out of the tabs on the retention base and away from the heat sink. NOTICE: Gently rock the heat sink and then lift it to remove it. 9. Lift the heat sink away from the microprocessor.
11. Remove the microprocessor from the socket. Leave the release lever extended in the release position so that the socket is ready for the new microprocessor. Installing the Microprocessor NOTICE: You must position the microprocessor package correctly in the socket to avoid permanent damage to the microprocessor and the computer. 1. If the release lever on the ZIF socket is not extended to the release position, move it to that position. 2.
Removing the Front I/O Panel CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in "Safety Instructions." 1. Shut down the computer. 2. Turn off any attached devices and disconnect them from their electrical outlets. NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack. 3. Disconnect the power cable from your computer, and then press the power button to ground the system board. 4.
Note the routing of the DC power cables underneath the tabs in the computer frame as you remove them from the system board and drives. It is important to route these cables properly when you replace them to prevent them from being pinched or crimped. 6. Remove the two screws that secure the power supply to the back of the computer. 7. Press the "PUSH" button located on the floor of the computer frame. 8. Slide the power supply toward the front of the system approximately 1 inch. 9.
NOTICE: The system board and the metal tray are attached and are removed as one piece. 5. 6. Remove or move any components that restrict access to the system board. Disconnect all cables from the system board. Before you remove the existing system board, visually compare the replacement system board to the existing system board to make sure that you have the correct part. 7. Pull up on the tab and slide the system board toward the front of the computer; lift it up and away. 8.
