CHECK THE SYSTEM
Monitoring battery power
The computer's main battery light gives you an indication of
the main battery's current charge:
❖
Glows green when the battery is fully charged
❖
Glows amber while the battery is being charged
❖
Does not glow if the external power source is
disconnected or if the battery is completely discharged
Setting battery alarms
Your computer can be configured to warn you when the
battery is running low. For more information, see "Setting
battery alarms" in the electronic user's guide.
Changing the main battery
When your battery power is running low, you have two
options: connect the computer to an AC power source or
install a charged battery.
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.
When handling a battery, be careful not to drop it or short-circuit its
terminals.
If your battery discharges fully, your information will be lost. Be sure
to save your work often.
