4. Using the Notebook PC 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 Lithium-Ion (Li-Ion) battery cells housed together. Only one battery pack can be inserted into the Notebook PC. 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 internal battery at the same time as long as it is plugged into an electrical outlet. CAUTION! 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. Battery Power System The Notebook PC is designed to work with a removable battery pack located inside the battery pack compartment. 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 environment, 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. Lithium-Ion (Li-Ion) Battery Advantages Over Traditional Nickel Metal Hydride (NiMH) • No memory effect - means you can connect the power adapter anytime you like for maximum convenience. You don't have to wait until the battery is completely used up. • No overheating - means safer and cooler usage and charging. This is better for your battery and your Notebook PC, so don't get burned with cheaper battery packs! • Higher capacity vs. weight - means longer usage per charge. You no longer have to carry a dozen heavy battery packs to get through the day because Li-Ion battery packs are lighter and more efficient than NiMH battery packs. • Longer life - means fewer battery purchases. This cuts down your battery cost. Charging the Battery Pack 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. When the orange charge LED is flashing, charging is required. The battery is charging when the orange LED is solid. When the LED is no longer lit, the battery pack is fully charged. NOTE: The battery stops charging if the temperature is too high or the battery voltage is too high. 53
