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 Hibernate mode and replace the
battery with a charged spare.
❖Save your work and turn off the computer.
If you do not set any of these options 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 of a low
battery charge condition, so you can take the necessary steps
to save your work.

your system shuts down.
