2. Lift the drive up (1), and then pull the drive out of the system board connector (2).
To install the solid-state drive module, reverse the removal procedure.
Battery
To remove the battery, use these procedures. The battery that comes with the computer provides power to
the r
eal-time clock. When replacing the battery, use a battery equivalent to the battery originally installed in
the computer. The computer comes with a 3 V lithium coin cell battery.
WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of re and
b
urns 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 (149°F).
Do not disassemble, crush, puncture, short external contacts, or dispose of in re or water.
Replace the battery only with the HP spare part that is designated for this product.
IMPORTANT: Before replacing the battery, back up the computer CMOS settings. When the battery is
r
emoved or replaced, the CMOS settings are cleared.
Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, be sure that you are discharged of static electricity by briey touching a
grounded metal object.
NOTE: You can extend the lifetime of the lithium battery by plugging the computer into an AC outlet. The
lithium b
attery is used only 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

Before removing the battery, follow these steps:
1. Prepare the computer for disassembly (Preparation for disassembly on page 21).
2. Remove the access panel (Access panel on page 21).
