Intelligent power	A microprocessor in the computer’s intelligent
supply *1	power supply detects the battery’s charge,
	automatically calculates the remaining battery
	capacity and protects electronic components
	from abnormal conditions such as a voltage
	overload from the AC adaptor. This can be
	specified in the Power Options.
Battery save mode *1	This feature lets you configure the computer in
	order to save battery power. This can be
	specified in the Power Options.
Panel power on/off *1	This feature automatically turns power to the
	computer off when the display panel is closed,
	and turns it back on when the display panel is
	opened. This can be specified in the Power
	Options.
Low battery	When battery power is exhausted to the point that
automatic	computer operation cannot be continued, the
Hibernation Mode *1	system automatically enters Hibernation Mode
	and shuts itself down. This can be specified in the
	Power Options.
Heat dispersal *1	To protect from overheating, the CPU has an
	internal temperature sensor. 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.
	Maximum Performance
	Turns on the fan first, then lowers the CPU
	processing speed if necessary.
	Battery Optimized
	Lowers the CPU processing speed first, then
	turns on the fan if necessary.

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.

TOSHIBA HDD	This feature uses the acceleration sensor built in
Protection	the computer to detect vibration and shocks, and
	automatically moves the hard disk drive’s
	read/write head to a safe position in order to
	reduce the risk of damage that could be caused
	by head-to-disk contact. Refer to the Using the
	Hard Disk Drive (HDD) Protection section in
	Chapter 4, Operating Basics, for more details.
