Chapter 03: Battery Usage and Care 23
When fully charged, the battery indicator will change to green and
the battery’s charge will be maintained while connected to the
external power source. When the computer is disconnected from
the electrical outlet, the battery indicator will turn off.
NOTE: The time to fully recharge the battery is approximately 90 –
100 minutes when the computer is powered off. The time to fully
recharge the battery when the computer is in use varies according
to the power requirements of the operations that the computer is
performing while charging.
Problems Charging the Battery
Environmental conditions can affect the ability of the computer
to charge the battery. If the battery is too hot from either being
used in your computer or being exposed to an overly hot
environment, the battery may not charge when you connect the
computer to an electrical outlet.
If this occurs, disconnect the computer from the electrical outlet
and allow it and the battery to cool to room temperature. Then
reconnect the computer to an electrical outlet to continue
charging the battery.
Battery Status
Both Windows XP and Windows Vista have an applet in the
Control Panel that will display an icon in the Windows taskbar
indicating when the computer is running on battery power or is
attached to the AC adapter.
This applet also displays a meter that indicates approximately
how much of a charge is remaining in the battery.
Low Battery Warnings
A beeping sound will be heard once to alert you to a “Battery
Low” status.
