In addition, when your computer is connected to a docking device (docked), the Battery Meter window includes a Dock Battery tab, which displays the charge

level and current status of the docking device battery.

The following icons appear in the Battery Meter window:

The computer or docking device is running on battery power.

The computer is connected to AC power and the battery is charging.

The computer is connected to AC power and the battery is fully charged.

If the computer is connected to an electrical outlet, a

Charge Gauge

Before you

insert a

battery, press the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20

percent of the total battery charge. For example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery

has no charge.

Health Gauge

The battery operating time is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, batteries lose some

charge capacity, or battery health. To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no

lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. Each light represents incremental

degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery. See "Specifications" for

more information about the battery operating time.

NOTE:

When you press and hold the status button on the battery charge gauge for at least 3 seconds, the charge-level lights will first light to display

the current charge status. Then they switch to Health status where they represent incremental degradation when lit.

Low-Battery Warning

NOTICE:

To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then connect the computer to an electrical outlet.

You can also turn the computer off and install a second battery in the module bay. If the battery runs completely out of power, hibernate mode begins

automatically.

A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The computer beeps once, indicating that minimal battery

operating time remains. During that time, the speaker beeps periodically. If two batteries are installed, the low-battery warning means that the combined

charge of both batteries is approximately 90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low level. For
