Monitoring battery power

The computer's main battery light gives you an indication of
the main battery's current charge:
❖
Green indicates the AC adapter has fully charged the
battery.
❖
Amber indicates the AC adapter is charging the battery.
❖
The battery light does not glow if the external power
source is disconnected or if the battery is completely
discharged.
TECHNICAL NOTE: The RTC battery does not charge while the
computer is turned off, even if the AC adapter is attached.
The RTC battery charges when the computer is powered on.
This message may vary by model.
The RTC battery does not charge while the computer is turned off
even if the AC adapter is attached.
TECHNICAL NOTE: The computer drains the battery faster at low
temperatures. Check your remaining charge frequently if you are
working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based on your
current rate of power use and other factors such as the age of the
battery.
TECHNICAL NOTE: When your computer is using all of the power
provided by the AC Adapter to run applications, features, and
devices, the recharging of the battery cannot occur. Your computer's
Power Saver utility can be used to select a power level setting that
reduces the power required for system operation and will allow the
battery to recharge.
