What is the difference between Standby, Suspend to RAM and Suspend to DISK?

A. Standby is simply a “cat nap” mode that keeps the unit running but in a very low power setting. Pressing a key will bring the unit back up as normal. Suspend to RAM sends all of the active information to RAM and shuts down all other system functions. It uses battery or AC power to keep the RAM powered in order to keep your information intact. If all power is shut off, your work will be lost. Pressing a key will resume your session. Suspend to DISK is a full hibernation mode for the unit. It will physically write all data from RAM and video memory to a special location on your hard disk (the suspend to disk partition) and shut down all power for the unit. This mode is a more long term Suspend mode. To resume you must press the power button as you would for a normal boot.
