Introduction
Disks
RTC battery
The internal RTC battery backs up the Real Time
Clock (RTC) and calendar.
AC adaptor
The AC adaptor provides power to the system
and recharges the batteries when they are low. It
comes with a detachable power cord. It encloses
2-pin or 3-pin plug type.
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
section in
Chapter 2, The Grand Tour.

Disclaimer (HDD Drive Capacity)
1 Gigabyte (GB) means 1000 Ч 1000 Ч 1000 = 1,000,000,000 bytes using
powers of 10. The computer operating system, however, reports storage
capacity using powers of 2 for the definition of 1 GB = 1024 Ч 1024 Ч 1024
= 1,073,741,824 bytes, and therefore may show less storage capacity.
Available storage capacity will also be less if the product includes one or
more pre-installed operating systems, such as Microsoft Operating System
and/or pre-installed software applications, or media content. Actual
formatted capacity may vary.
