Power System

Using AC Power

The Notebook PC power is comprised of 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 Notebook PC.Your Notebook PC comes with a universal AC-DC adapter.That means that you may connect the power cord to any 100V-120V as well as 220V-240V outlets without setting switches or using power converters. Different countries may require that an adapter be used 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 when bringing power adapters to another country.

You can buy travel kits for the Notebook PC that includes power and modem adapters for almost every country.

WARNING! DO NOT connect the AC power cord to an AC outlet prior to connecting the DC plug to the Notebook PC. Doing so may damage the AC-DC adapter.
