Chapter 3: Getting Started
This Eee PC may come with either a two or three-prong plug 
depending on territory to fit your wall outlet. If a three-prong 
plug is provided, you must use a grounded AC outlet or use a 
properly grounded adapter to ensure safe operation of the Eee 
PC.
THE POWER ADAPTER MAY BECOME WARM TO HOT WHEN IN 
USE. BE SURE NOT TO COVER THE ADAPTER AND KEEP IT AWAY 
FROM YOUR BODY.
Power System
Using AC Power
The Eee PC power comprises two parts, the power adapter and 
the battery power system. The power adapter converts AC power 
from a wall outlet to the DC power required by the Eee PC. Your Eee 
PC comes with a universal AC-DC adapter for connection to any 
100V-120V as well as 220V-240V outlets without setting switches or 
using power converters. Different countries may require an adapter 
to connect the provided US-
standard AC power cord to a 
different standard. Most hotels 
will provide universal outlets to 
support different power cords 
as well as voltages. It is always 
best to ask an experienced 
traveler about AC outlet 
voltages before travelling.
With the AC power cord 
connected to the AC-DC converter, connect the AC power cord to 
an AC outlet (preferably with surge-protection) and then connect 
the DC plug to the Eee PC. Connecting the AC-DC adapter to the AC 
outlet first allows you to test the AC outlet’s power and the AC-DC 
converter itself for compatibility problems before connecting the DC 
power to the Eee PC. The power indicator on the adapter (if available) 
will light if the power is within accepted ranges.
