Battery The battery that comes with your workstation provides power to the real-time clock and has a lifetime of about three years. When replacing the battery, use a battery equivalent to the battery originally installed on the workstation. The workstation comes with a 3-volt lithium coin cell battery. NOTE: The lifetime of the lithium battery can be extended by plugging the workstation into a live AC wall socket. The lithium battery is only used when the workstation is NOT connected to AC power. WARNING! This workstation contains an internal lithium manganese dioxide battery. There is a risk of fire and burns if the battery is not handled properly. To reduce the risk of personal injury: Do not attempt to recharge the battery. Do not expose to temperatures higher than 140°F (60°C). Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water. Replace the battery only with the HP spare designated for this product. CAUTION: Before replacing the battery, it is important to back up the workstation CMOS settings. When the battery is removed or replaced, the CMOS settings will be cleared. Refer to Section 2.2 for information on backing up the CMOS settings. NOTE: HP encourages customers to recycle used electronic hardware, HP original print cartridges, and rechargeable batteries. For more information about recycling programs, go to http://www.hp.com/ recycle. CAUTION: Static electricity can damage the electronic components of the workstation or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. 1. Prepare the workstation for disassembly (Preparation for disassembly on page 59). 2. Remove the access panel and rotate the workstation so the system board is parallel to the table to make it easier to work on (Access panel on page 61). NOTE: It may be necessary to remove an expansion card to gain access to the battery. 3. Locate the battery and battery holder on the system board. 4. Depending on the type of battery holder on your system board, complete the following instructions to replace the battery: 92 Chapter 7 Removal and replacement procedures ENWW
