On battery * This feature lets you configure the computer in
order to save battery power. This can be
specified in the Power Options.
Critical battery
action * When battery power is exhausted to the point that
computer operation cannot be continued, the
system automatically enters Hibernation Mode
and shuts itself down. This can be specified in the
Power Options.
Processor power
management * To protect against overheating, the processor has
an internal temperature sensor so that, if the
computer’s internal temperature rises to a certain
level, the cooling fan is turned on or the
processing speed is lowered. This can be
specified in the Power Options.
If the processor’s temperature reaches an unacceptably high level with
either setting, the computer will automatically shut down to prevent any
damage - in this instance any unsaved data in memory will be lost.
Hibernation Mode This feature lets you turn off the power to the
computer without exiting from your software.
The contents of main memory are automatically
saved to the hard disk drive so that when you
next turn the power on again, you can continue
working right where you left off. Refer to the
Turning off the power section in Chapter 3,
Getting Started , for more details.
Sleep Mode If you have to interrupt your work, you can use
this feature to allow you to turn off power to the
computer without exiting from your software.
Data is maintained in the computer’s main
memory so that when you next turn on the power,
you can continue working right where you left off.
