If the computer is connected to an electrical outlet, a icon appears.
Charge Gauge
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.
