Toshiba C855-S5133 User Manual

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 (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 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. 

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:

While on the desktop, click the battery ( ) icon in the 
notification area.

Click More power options.

The Power Options window appears.

Click Change plan settings under the power plan to be 
customized.

The Edit Plan Settings window appears.
