  • Page 27: Electrostatic Discharge Information

    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.

  • Page 28: Personal Grounding Methods And Equipment

    ● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. Personal Grounding Methods and Equipment Use the following equipment to prevent static electricity damage to equipment: ● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords.

  • Page 45: Memory

    Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2- SDRAM) dual inline memory modules (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 4 GB of memory configured in a high- performing dual channel mode.
  • Page 46 Figure 6-10 DIMM Socket Locations Table 6-1 DIMM Socket Locations Item Description Socket Color DIMM1 socket, Channel A (populate first) Blue DIMM2 socket, Channel B Blue NOTE: A DIMM must occupy the DIMM1 socket. The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
  • Page 47 CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other. Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.
