This section contains information on the computer’s power system,
including the AC Adapter, the battery pack, recharging the battery,
and tips for conserving battery power.
The power system is comprised of two parts, the AC Adapter and the
battery pack. The AC Adapter converts AC power from a wall outlet
to the DC power required by the computer.

Before using the computer on battery power for the first time, check
the battery status icon in the Windows System Tray to make sure the
battery is fully charged.
See “Battery Status” later in this section for a description and
explanation of the Windows’ Battery Status icon. The battery takes
about 4 hours to reach a full charge when the system is in a powered
off state. Whenever possible, always charge the battery completely.
Battery Status
Windows 7 has 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 indicates how many percent of power is remaining in
the battery.
Battery Low Warning
When the battery initially reaches the “Battery Low” state,
approximately 10 ~ 15 minutes of the usable battery life is left.
You will see the Battery LED Indicator change to red blinking to alert
you the “Battery Low” status.
