3 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.
4 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. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
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.
● 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. ● 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
● Do not place computers so near each other that they are subject to each other’s re-circulated or preheated air. ● 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. Never use solvents or flammable solutions to clean the computer. 2.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the Computer Case on page 20. When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions on page 20 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.
Tools and Software Requirements To service the computer, you need the following: ● Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001) ● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver) ● Phillips #2 screwdriver ● Diagnostics software ● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 166527-002) Screws The screws used in the computer are not interchangeable.
● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. For more information about preventing electrostatic damage, refer to Electrostatic Discharge Information on page 17 ● Do not use excessive force when inserting a drive. ● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.

Interpreting POST Diagnostic Front Panel LEDs and Audible Codes This section covers the front panel LED codes as well as the audible codes that may occur before or during POST that do not necessarily have an error code or text message associated with them. WARNING! When the computer is plugged into an AC power source, voltage is always applied to the system board.
Table A-2 Diagnostic Front Panel LEDs and Audible Codes (continued) Activity Beeps Possible Cause Recommended Action Red Power LED flashes four times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. 4 Power failure (power supply is overloaded). 1. Open the hood and ensure the 4 or 6-wire power supply cable is seated into the connector on the system board. 2.
Table A-2 Diagnostic Front Panel LEDs and Audible Codes (continued) Activity Beeps Possible Cause Recommended Action Red Power LED flashes eight times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. 8 Invalid ROM based on bad checksum. 1. Reflash the system ROM with the latest BIOS image. 2. Replace the system board. Red Power LED flashes nine times, once every second, followed by a two second pause.
Table A-2 Diagnostic Front Panel LEDs and Audible Codes (continued) Activity Beeps Possible Cause Recommended Action Red Power LED flashes eleven times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. 11 The current processor does not support a feature previously enabled on this system. 1. Install a TXT capable processor. 2. Disable TXT in the Computer Setup (F10) utility. 3. Reinstall the original processor.

C Power Cord Set Requirements The power supplies on some computers have external power switches. The voltage select switch feature on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power supplies on those computers that do not have external power switches are equipped with internal switches that sense the incoming voltage and automatically switch to the proper voltage.
