Upgrading system memory The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs). The memory sockets on the system board are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 32 GB of memory configured in a high-performing dual-channel mode.
DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this configuration, 4 GB will run as dual-channel and 1 GB will run as single-channel. ● In any mode, the maximum operational speed is determined by the slowest DIMM in the system. IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules.
3. Open both latches (1) of the memory module socket and insert the memory module into the socket (2). Press the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position (3). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Populate the black DIMM sockets before the white DIMM sockets.
3. Rotate the slot cover release latch to the open position. 4. Locate the correct vacant expansion socket on the system board and the corresponding expansion slot on the back of the computer chassis. 5. Before installing an expansion card, remove the expansion slot cover or the existing expansion card. NOTE: Before removing an installed expansion card, disconnect any cables that may be attached to the expansion card. a.
b. 18 If you are removing a PCI Express ×1 card, hold the card at each end and carefully rock it back and forth until the connectors pull free from the socket.

c. If you are removing a PCI Express ×16 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. 6. Store the removed card in anti-static packaging. 7.
8. 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 socket. 9.

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. To insert the new battery, slide one edge of the replacement battery under the lip of the holder (1) with the positive side up. Push the other edge down until the clamp snaps over the other edge of the battery (2). Type 3 a. Pull back on the clip (1) that is holding the battery in place, and remove the battery (2). 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. 40 5.
7. Reset the date and time, your passwords, and any special system setups using Computer Setup. 8. 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 staticsensitive 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.
