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.
As the AC adaptor is universal, it can receive a
range of AC voltages from 100 to 240 volts,
however you should note that the output current
varies among different models. Using the wrong
adaptor can damage your computer. Refer to the
AC adaptor section in Chapter 2, The Grand
Tour.
