Lithium coin cell battery The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years. See the appropriate removal and replacement chapter for the chassis you are working on in this guide for instructions on the replacement procedures. WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or expose it to temperatures higher than 140°F (60°C). Do not attempt to recharge the battery. NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste. In order to forward them to recycling or proper disposal, please use the public collection system or return them to HP, their authorized partners, or their agents. SATA hard drives Table 3-3 SATA hard drive characteristics Serial ATA hard drive characteristics Number of pins/conductors in data cable Number of pins in power cable Maximum data cable length Data interface voltage differential Drive voltages Jumpers for configuring drive Data transfer rate 7/7 15 100 cm (39.37 in) 400 mV-700 mV 3.3 V, 5 V, 12 V N/A 6.0 Gbps 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. SATA hard drive cables SATA data cable Always use an HP-approved SATA 6.0 Gbps cable as it is fully backwards compatible with the SATA 1.5 Gbps drives. Current HP desktop products ship with SATA 6.0 Gbps hard drives. SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius. The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive. 16 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
