System board connections See the following illustration and table to identify the system board connectors for your model.
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 64 GB of memory configured in a high-performing dual-channel mode.
should be populated with the other two 1 GB DIMMs. With this configuration, 4 GB runs as dual-channel and 1 GB runs 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.

A Battery replacement The battery that comes with the computer provides power to the real-time clock. When replacing the battery, use a battery equivalent to the battery originally installed in the computer. The computer comes with a 3 V lithium coin cell battery. 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 (1). When the battery pops up, lift it out (2).
b. To insert the new battery, slide one edge of the replacement battery under the holder’s lip with the positive side up (1). Push the other edge down until the clamp snaps over the other edge of the battery (2). Type 3 a. Pull back 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. 42 8.
10. Reset the date and time, your passwords, and any special system setups using Computer Setup. 11. Lock any security devices that you disengaged when you removed the computer access panel.
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 1 hr before you turn off the power. If you operate the unit immediately, it may malfunction while reading.
