Removing the computer access panel To access internal components, you must remove the access panel: 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as compact discs or USB flash drives, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Replacing the computer access panel Place the panel on the computer (1) then slide it forward (2) and tighten the thumbscrew (3) to secure the panel in place.
Removing the front bezel 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as compact discs or USB flash drives, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Removing an optical drive bezel blank On some models, there is a bezel blank covering the slim optical drive bay. Remove the bezel blank before installing an optical drive. To remove the bezel blank: 1. Remove the access panel and front bezel. 2. To remove the bezel blank, press upward on the bottom tab and press downward on the top tab on the right side of the blank (1), and then rotate the blank off the front of the bezel (2).
System board connections Refer to the following illustration and table to identify the system board connectors for your model. 10 No.
Installing additional memory The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to two industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 16-GB of memory configured in a high-performing dual channel mode.
channel and the remainder is assigned to single channel. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. ● In any mode, the maximum operational speed is determined by the slowest DIMM in the system. Installing DIMMs CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules.
6. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM sockets on page 11 for more information. 7.
Removing or installing an expansion card The computer has three PCI Express x1 expansion slots and one PCI Express x16 expansion slot. NOTE: You can install a PCI Express x1, x8, or x16 expansion card in the PCI Express x16 slot. For dual graphics card configurations, the first (primary) card must be installed in the PCI Express x16 slot. To remove, replace, or add an expansion card: 1. Remove/disengage any security devices that prohibit opening the computer. 2.
b. If you are removing a PCI Express x1 card, hold the card at each end and carefully rock it back and forth until the connectors pull free from the socket. Lift the card straight up (1) then away from the inside of the chassis (2) to remove it. Be sure not to scrape the card against other components.
c. 9. If you are removing a PCI Express x16 card, pull the retention arm on the back of the expansion socket away from the card and carefully rock the card back and forth until the connectors pull free from the socket. Lift the card straight up then away from the inside of the chassis to remove it. Be sure not to scrape the card against other components. Store the removed card in anti-static packaging. 10.
11. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis (1) so that the bottom of the bracket on the card slides into the small slot on the chassis. Press the card straight down into the expansion socket on the system board (2). NOTE: When installing an expansion card, press firmly on the card so that the whole connector seats properly in the expansion card slot. 12.

A Battery replacement The battery installed on the computer provides power to the real-time clock. When replacing the battery, use a battery equivalent to the battery originally installed on the computer. The computer has a 3-volt lithium coin cell battery installed. WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of fire and burns if the battery is not handled properly. To reduce the risk of personal injury: Do not attempt to recharge the battery.
b. Slide the replacement battery into position, positive side up. The battery holder automatically secures the battery in the proper position. Type 2 a. To release the battery from its holder, squeeze the metal clamp that extends above one edge of the battery. When the battery pops up, lift it out (1). b. To insert the new battery, slide one edge of the replacement battery under the lip of the holder with the positive side up.
b. Insert the new battery and position the clip back into place. NOTE: After the battery has been replaced, use the following steps to complete this procedure. 8. Replace the computer access panel. 9. Plug in the computer and turn on power to the computer. 10. Reset the date and time, your passwords, and any special system setups using Computer Setup. 11. Lock any security devices that were disengaged when the computer access panel was removed.
B Electrostatic discharge A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. Preventing electrostatic damage To prevent electrostatic damage, observe the following precautions: ● Avoid hand contact by transporting and storing products in static-safe containers. ● Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
C Computer operating guidelines, routine care and shipping preparation Computer operating guidelines and routine care Follow these guidelines to properly set up and care for the computer and monitor: ● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold. ● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.
Optical drive precautions Be sure to observe the following guidelines while operating or cleaning the optical drive. Operation ● Do not move the drive during operation. This may cause it to malfunction during reading. ● Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the power. If you operate the unit immediately, it may malfunction while reading.
