RTC battery The computer has an internal battery to back up the
internal Real Time Clock (RTC) and calendar.
Universal AC adaptor The universal AC adaptor provides power to the system
and recharges the batteries when they are low. It comes
with a detachable power cord.
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. See the universal AC adaptor
section in Chapter 2, The Grand Tour.
