5 Serial ATA (SATA) Drive Guidelines and Features NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel ATA (PATA) drives are supported. SATA Hard Drives Serial ATA Hard Drive Characteristics Number of pins/conductors in data cable 7/7 Number of pins in power cable 15 Maximum data cable length 39.37 in (100 cm) Data interface voltage differential 400-700 mV Drive voltages 3.3 V, 5 V, 12 V Jumpers for configuring drive N/A Data transfer rate 3.
SMART ATA Drives The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
6 Routine Care and Disassembly Preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

NOTE: 700 volts can degrade a product. Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD.
Grounding the Work Area To prevent static damage at the work area, use the following precautions: ● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ● Use static-dissipative mats, foot straps, or air ionizers to give added protection. ● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas.
Operating Guidelines To prevent overheating and to help prolong the life of the computer: ● 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. ● Never restrict the airflow into the computer by blocking any vents or air intakes.
To clean the computer case, follow the procedures described below: ● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water. ● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
Cleaning the Mouse Before cleaning the mouse, ensure that the power to the computer is turned off. ● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly. ● To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 39.
Cables and Connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.
7 Removal and Replacement Procedures – Microtower Chassis Adherence to the procedures and precautions described in this chapter is essential for proper service. After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify that all components operate properly. NOTE: Not all features listed in this guide are available on all computers. Serviceability Features The computers include features that make them easy to upgrade and service.

Memory Description Spare part number PC3-10600 for use in 3400/3405/3410 models 4-GB 585157-001 2-GB 635803-001 1-GB 635802-001 PC3-12800 for use in 3500/3505 models 4-GB 671613-001 2-GB 671612-001 The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DDR3-SDRAM DIMMs The system board offers two memory sockets. These memory sockets are populated with at least one preinstalled DIMM.
Populating DIMM Sockets Populate the DIMM sockets in the following order: XMM1, XMM2 or Channel A, Channel B. Figure 7-3 DIMM Socket Locations (HP Pro 3400 model shown) Table 7-1 DIMM Sockets Description Socket Color XMM1 socket, Channel A (populate first) HP Pro 3400: Black Insertion Order 1 HP Pro 3405/3410/3500: Blue XMM2 socket, Channel A HP Pro 3400: Black NOTE: HP Pro 3505 models label this connector as XMM3.
populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A.
4. Open both latches (1) of the memory module socket , and remove the memory module from the socket (2). Figure 7-4 Removing a DIMM To install a memory module, reverse the removal procedures. NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. A DIMM must occupy the XMM1 socket. To create a dual-channel memory configuration, the memory capacity of Channel A must equal the memory capacity of Channel B.

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. If you are removing a PCI Express x1 card, hold the card at each end and carefully rock it back and forth until the connectors pull free from the socket. Be sure not to scrape the card against the other components. Figure 7-9 Removing a PCI Express x1 Expansion Card c. If you are removing a PCI Express x16 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.
7. If you are not installing a new expansion card, install an expansion slot cover to close the open slot. CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. 8.
10. Connect external cables to the installed card, if needed. Connect internal cables to the system board, if needed. 11. Reconfigure the computer, if necessary. Refer to Computer Setup (F10) Utility on page 7 for instructions on using Computer Setup. Cable Management Always follow good cable management practices when working inside the computer. ● Keep cables away from major heat sources like the heat sink. ● Do not jam cables on top of expansion cards or memory modules.
