the configuration information is erased if the system is turned off or
unplugged from the electrical outlet. In this case, you must enter the System
Setup program and reset the configuration options.
CAUTION: A new battery can explode if it is incorrectly installed. Replace the
battery only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
