Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the AC power cord from the AC outlet and disconnect any external devices.
Installing additional memory The computer comes with small outline, dual inline memory modules (SODIMMs). SODIMMs The memory sockets on the system board can be populated with up to two industry-standard SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum memory support, you can populate the system board with up to 32 GB (EliteDesk 800 and ProDesk 600) or 16 GB (EliteDesk 705 and ProDesk 400) of memory.
Populating SODIMM sockets There are two SODIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM3. The DIMM1 socket operates in memory channel B. The DIMM3 socket operates in memory channel A.
Installing SODIMMs CAUTION: You must disconnect the AC power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board. The memory module sockets have gold-plated metal contacts.

A 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.
B 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: 44 ● 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.
Shipping preparation Follow these suggestions when preparing to ship the computer: 1. Back up the HDD files to an external storage device. Be sure that the backup media is not exposed to electrical or magnetic impulses while stored or in transit. NOTE: The HDD locks automatically when the system power is turned off. 2. Remove and store all removable media. 3. Turn off the computer and external devices. 4. Disconnect the AC power cord from the AC outlet, then from the computer. 5.
