Figure 3-35. Locating the battery on the system board
WARNING: The system board contains a lithium-ion battery pack. There is a risk
of fire and chemical burn if the battery pack is handled improperly. Do not
disassemble, crush, puncture, short external contacts, dispose in water or fire, or
expose it to termperatures higher than 60ºC (140ºF).
CAUTION: Before removing the access panel, ensure that the workstation is
turned off, all cables are disconnected from the back of the workstation, and the
power cord is disconnected from the grounded AC outlet.
CAUTION: Static electricity can damage the electronic components of the
workstation. Before beginning these procedures, be sure you are discharged of
static electricity by briefly touching a grounded metal object.
