Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
● Place items on a grounded surface before removing them from their container. ● Always be properly grounded when touching a sensitive component or assembly. ● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.
Recommended Materials and Equipment Materials and equipment that are recommended for use in preventing static electricity include: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwea
● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure, and the same operating guidelines listed above will still apply. ● Keep liquids away from the computer and keyboard. ● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine Care General Cleaning Safety Precautions 1.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions on page 38 before following these procedures: CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys. ● Visible debris underneath or between the keys may be removed by vacuuming or shaking. ● Canned, pressurized air may be used to clean debris from under the keys.

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 four 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 either 4 GB, 8 GB, or 16-GB of memory configured in a high-performing dual channel mode.
Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. DIMM Socket Locations – HP Pro 2110 When installing memory modules: ● If installing only one memory module, install it in DIMM1. ● If installing 2 memory modules: ◦ 2 matching memory modules - install in DIMM1 and DIMM2. ◦ 2 non-matching memory modules - install in DIMM1 and DIMM2. Install the larger (GB) module in DIMM1 and smaller (MB) module in DIMM2.
DIMM Socket Locations – HP Pro 3120 When installing memory modules: ● If installing only one memory module, install it in DIMM1. ● If installing 2 memory modules: ● ● ◦ 2 matching memory modules - install in DIMM1 and DIMM3. ◦ 2 non-matching memory modules - install in DIMM1 and DIMM3.
