Monitoring main battery power

What to do when the main battery runs low
When the main battery runs low you can
:
❖
Plug the computer into an external power source and
recharge the main battery
❖
Place the computer into Hibernation mode and replace
the main battery with a charged spare
❖
Connect the computer to an optional high capacity
battery (if available for your computer)
❖
Save your work and turn off the computer
If you do not manage to do any of these things before the
main battery completely runs out of power, the computer
automatically enters Hibernation mode and turns itself off.
Hibernation mode keeps track of where you were, so that
when you turn on the power again, you can continue where
you left off.
If you have Hibernation mode enabled (the default), the
computer copies the details of your open programs and files
to the hard disk before shutting down. For more information
on using Hibernation, see
.
Setting battery alarms
Your computer can be configured to warn you when the
battery is running low.
You can set multiple alarms. Each alarm can be set to alert
you when a specified percentage of remaining battery power
has been reached. You can set how the warning occurs: sound
an alarm, display a message, both, or none. You can also set
the computer to enter Standby mode or Hibernate mode or to
completely power down when the alarm goes off.
