Basic Power Management Schemes
This section discusses the basic schemes of power management when the computer is operating on battery power or using AC power.
Standby vs. Hibernation
Hibernation is a state where the contents of memory are stored in a special file on the hard disk, and Standby simply keeps a small holding current through the memory to keep the data. You are more likely to sustain loss of data in Standby mode so it is recommended to save all open files before entering Standby.
