Standby
Puts the system into Standby mode, a power management state that saves the
state of the system and peripheral devices in memory (RAM). Power
consumption reduces to a minimum, and the system remains on. To return the
system to the active state, press any key or the power button on your computer.
Hibernate
Provides for the lowest level of power consumption. The system writes the
state of the system and peripheral devices to the hard disk and turns off the
system power. To return the system to the original state, use the power button
to turn on power. The system saves the data in the Save to Disk Partition on the
hard drive.
LCD (Video) Standby
Turns off the video display to save power. If you turn off the Video Standby
timer, the display remains active except when the system enters Standby mode.
The video display system is one of the largest consumers of power in the
system.
