Monitoring battery power
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.
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
❖ Place the computer into Hibernation mode and replace the
battery with a charged spare (not included with your computer)
❖ Save your work and turn off the computer
If you do not 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 that when you turn on the power again,
you can continue where you left off.
Setting battery notifications
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 also set the computer to enter Sleep mode or
Hibernation mode or to completely shut down when the notification
goes off.
To change the default notification settings:
1 While on the desktop, click the Battery ( ) icon in the
notification area.
2 Click More power options.
The Power Options window appears.
3 Click Change plan settings under the power plan to be
customized.
The Edit Plan Settings window appears.
