AC Power System

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. The battery pack consists of a set of battery cells housed together. The AC Adapter's primary

function is to provide power to the Notebook PC which also charges the battery pack. When the power

adapter is connected to the Notebook PC, it provides power to the Notebook PC and charges the inter-

nal battery at the same time as long as it is plugged into an electrical outlet.

IMPORTANT! To protect your Notebook PC from damage, use only the power adapter

that came with this Notebook PC because each power adapter has its own power

output ratings.

The Notebook PC is designed to work with a removable battery pack. A fully charged pack will provide

several hours of battery life, which can be further extended by using power management features through

the BIOS setup. The battery system implements the Smart Battery standard under the Windows envi-

ronment, which allows the battery to accurately report the amount of charge percentage left in the

battery. Additional battery packs are optional and can be purchased separately through a Notebook PC

retailer. Before using the Notebook PC on battery power for the first time, check the battery icon in the

Windows task bar to make sure that the battery is fully charged. Charging the battery takes a few hours

when the Notebook PC is powered OFF.

You can charge the battery pack by using the power adapter. When the power adapter is plugged in, the

inserted battery pack automatically recharges whether your Notebook PC is ON or OFF. It takes a few

hours to receive a full charge when the power is OFF but takes twice as long when the Notebook PC is

in use. The battery is charging when the orange LED is solid. When the LED is OFF, the battery pack is

charged.

NOTE: The battery stops charging if the temperature is too high or the battery voltage

is too high. BIOS provides a smart battery refreshing function.
