Wait a few moments after turning on the computer before trying to 
monitor the remaining battery power. The computer needs this time 
to check the battery’s remaining capacity and perform its 
calculations.

Move the pointer over the power icon in the notification area, see 

 for more 

information on the notification area. A pop-up message displays the 
remaining battery power as a percentage.

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.

When the main battery runs low you can:

❖

Plug the computer into an external power source and recharge 
the main battery

❖

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 internal 
storage drive before shutting down. For more information on using 
Hibernation, see
