Battery Power System; Charging The Battery Pack - Asus L8400B User Manual

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 imple-
ments the Smart Battery standard under the Windows environment, which allows the battery to accu-
rately 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
(compared with traditional Nickel Metal Hydride (NiMH)
• No memory - means 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 effi-
cient than NiMH battery packs.
• Longer life - means fewer battery purchases. This cuts down your battery replacement 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 will automatically recharge 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 much longer 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 will stop charging if the temperature is too high or the battery
voltage is too high.
