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 “Using and configuring Hibernation mode” on page 78.

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.
