Monitoring battery power
With repeated discharges and recharges, the battery’s
capacity gradually decreases. A frequently used older
battery does not power the computer for as long as a new
battery, even when both are fully charged.
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 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,
or save your work and shut down your computer.
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 to completely shut down when the
notification goes off.
To change the default notification settings:
1 Right-click the
Battery ( ) icon in the notification area.
2 Click
Power Options in the pop-up menu.
3 Click
Change plan settings under the plan you wish to
change.
The Edit Plan Settings window appears.
4 Click

window appears.
