Charge Gauge
By either pressing once or pressing and holding the status button on the charge gauge on the battery, you
can check:
Battery charge (check by pressing and releasing the status button)
Battery health (check by pressing and holding the status button)
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. That is, a battery can
show a status of "charged" but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press and release 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.
Check the Battery Health
To check the battery health using the charge gauge, 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 the specifications in your User's Guide.
Low-Battery Warning
NOTICE:
To avoid losing or corrupting data, save your work immediately after a low-battery warning, and then
connect the computer to an electrical outlet. If the battery runs completely out of power, hibernate mode begins
automatically.
By default, a pop-up window warns you when the battery charge is approximately 90 percent depleted.
You can change the settings for the battery alarms. See your User's Guide for information about accessing
the Power Options Properties window.

Charging the Battery

NOTE:
When the computer is turned off, the AC adapter charges a completely discharged battery to 80 percent in
about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer with the computer turned on. You
can leave the battery in the computer for as long as you like. The battery's internal circuitry prevents the battery
from overcharging.
When you connect the computer to an electrical outlet or install a battery while the computer is
connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary,
the AC adapter then charges the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the battery may
not charge when you connect the computer to an electrical outlet.
