The remaining battery charge is indicated on the top-left side
of the dialog box.
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 battery runs low
When the battery runs low you can:
❖
Plug the computer into an external power source and
recharge the battery.
❖ Put the computer in Hibernate mode and replace the
battery with a charged spare.
❖ Save your work and turn off the computer.
If you do not set any of these options 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, when you turn on the
power again, you can continue where you left off.
The computer stores the information on what you were doing
until the battery runs out of power. If you have Hibernation
mode enabled (the default), the computer copies the details of
your open programs and files to the hard disk before shutting
down.
