Monitoring main battery power
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.
❖
Put the computer in Hibernation mode and replace the
main battery with a charged spare.
❖
Connect the computer to the optional high capacity
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, when
you turn on the power again, you can continue where you left
off.
The computer stores information on what you were doing
until the main 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.
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.
