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 Number of pins in power cable Maximum data cable length 39.37 in (100 cm)
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.
Identifying the Chassis, 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.
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.
● Keep electrostatic sensitive parts in their containers until they arrive at static-free stations. ● 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.
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 ●...
● Do not stack computers on top of each other or place computers so near each other that they are subject to each other’s re-circulated or preheated air. ● 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.
Cleaning the Keyboard Follow all safety precautions in General Cleaning Safety Precautions on page 28 before cleaning the keyboard. To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the Computer Case on page When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions on page 28...
Power Supply Fan The power supply fan is a variable-speed fan based on the temperature in the power supply. CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Hard Drives Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares. ● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.”...
