RTC battery The RTC battery that comes with the computer provides power to the real-time clock. When replacing the battery, use a battery equivalent to the battery originally installed in the computer. The computer comes with a 3-volt lithium coin cell battery. WARNING! The computer 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 60°C (140°F). 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. IMPORTANT: Before replacing the battery, it is important to back up the computer CMOS settings. When the battery is removed or replaced, the CMOS settings will be cleared. Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. NOTE: The lifetime of the lithium battery can be extended by plugging the computer into a live AC outlet. The lithium battery is only used when the computer is NOT connected to AC power. 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. To locate the battery on the system board, see Internal components on page 21. 1. Prepare the computer for disassembly (see Preparing to disassemble the computer on page 16). 2. Remove the base unit rear and front access panels (see Base unit access covers on page 17). 3. To release the battery from its holder, squeeze the metal clamp that extends above one edge of the battery. When the battery pops up, lift it out (1). 4. To insert the new battery, slide one edge of the replacement battery under the holder's lip with the positive side up. Push the other edge down until the clamp snaps over the other edge of the battery (2). 5. Replace the base unit front and rear access panels. See Base unit access covers on page 17. 6. Reconnect the power cord and any external devices, and then turn on the computer. 7. Reset the date and time, your passwords, and any special system setups using Computer Setup. 24 Chapter 4 Removal and replacement procedures
