The internal RTC battery backs up the Real Time
Clock (RTC) and calendar.
The AC adaptor provides power to the system
and recharges the batteries when they are low. It
comes with a detachable power cord which will
either have a 2-pin or 3-pin plug enclosure.
Because it is universal, it can receive a range of
AC voltage from 100 to 240 volts; however, the
output current varies among different models.
Using the wrong model can damage your
computer. Refer to the
chapter 2, The Grand Tour.
