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.

Heat dispersal *1	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 shuts down to prevent any damage - in this instance all 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.
