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 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 

You can set two notifications. Each notification 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 Sleep mode or Hibernation mode or to completely power 
down when the alarm goes off.

To change the default alarm settings:

Click Start, Control Panel, Mobile PC and then Power 
Options. 

The Power Options window appears.
