What to do when the battery runs low
When the battery runs low you can:
❖
Plug the computer into an external power source and
recharge the battery.
❖ Put the computer in Hibernation mode and replace the
battery with a charged spare.
❖ Save your work and turn off the computer.
If you don’t manage to do any of these things before the
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, when
you turn on the power again, you can continue where you left
off.
The computer stores the information on what you were doing
until the battery runs out of power. 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.
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 Stand by mode or Hibernation mode, or
to Turn Off when the alarm goes off.
To set an alarm:
1 Click Start, then click Control Panel.
The Control Panel window appears.
2 Click Performance and Maintenance.
