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
❖
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.
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 or touch the
