About System Standby/Hibernate
System standby/hibernate is a very useful power management tool. For example, after
the computer has entered a system standby mode, you can restart the computer more
quickly when compared to restarting after a normal shutdown operation. When the
computer resumes from a system standby or hibernation mode, the system restores the
exact last state of the computer. In Windows, the System standby and System
hibernate are defined as following:
•
System standby stores the current condition of the computer in RAM and stops
power supply to all but a few essential components. In a standby mode, the power
