DVD Super Multi (+-R Double Layer) drive
The full-size DVD Super Multi drive module lets you record data to
rewritable CDs as well as run either 12 cm (4.72") or 8 cm (3.15") CD/DVDs
without using an adaptor.
AC adaptor
The AC adaptor converts AC power to DC power and reduces the voltage
supplied to the computer. It can automatically adjust to any voltage from 100
to 240 volts and to a frequency of either 50 or 60 hertz, enabling you to use
the computer in almost any region.
To recharge the battery, simply connect the AC adaptor to a power source
and the computer. See Chapter 6 Power and Power-Up Modes .
