Sleep mode and hibernation can be combined: the contents of RAM are copied to the non-volatile storage and the computer enters sleep mode. This approach combines the benefits of sleep mode and hibernation: The machine can resume instantaneously, and its state, including open and unsaved files, survives a power outage.
Sleep mode has gone by various names, including Stand By, Suspend and Suspend to RAM. Machine state is held in RAM and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automatically enter ...
The shutdown-versus-sleep-mode debate has raged for years, and you’ve probably wondered about the answer a time or two yourself. ... Omega Computer Services advises that once you turn off the ...
An uninterruptible sleep state is a sleep state that will not handle a signal right away. It will wake only as a result of a waited-upon resource becoming available or after a time-out occurs during that wait (if specified when put to sleep). It is mostly used by device drivers waiting for disk or network IO (input/output).
When computers such as laptops go into hibernation mode to save energy by shutting down the processor, the state of the processor is stored on the computer's hard disk, so it can be restored when the computer comes out of hibernation, and the processor can take up operations where it left off.

Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
