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 

section in Chapter 2, The Grand Tour.

DVD-ROM drive

Some models are equipped with a full-size, DVD-ROM
drive module that lets you run either 12 cm (4.72") or 8 cm
(3.15") CD/DVDs without using an adaptor. It runs DVD-
ROMs at maximum 8 speed and CD-ROMs at maximum 24
speed. A Mode Control button turns power to the fixed
