powercfg must be run from an elevated command prompt, and, under Windows XP, it requires workstation Administrator or power user rights. Power Schemes are configured on a per-user basis. The most common cause of problems with power saving and hibernation on Windows systems is an incompatible device driver.
This approach combines the benefits of sleep mode and hibernation: The machine can resume instantaneously, but it can also be powered down completely (e.g. due to loss of power) without loss of data, because it is already effectively in a state of hibernation. This mode is called "hybrid sleep" in Microsoft Windows other than Windows XP.
Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers [1]) in computing is powering down a computer while retaining its state. When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage. When the computer is turned on the RAM is restored and ...
In Windows XP only, there is a "Shut Down" menu that provides access to Standby, Hibernate, Turn off, Restart, Log Off, and Switch User. This is because, by default in Windows XP, pressing Ctrl+Alt+Delete opens the Task Manager instead of opening a dialog that provides access to the Task Manager in addition to the options mentioned above.
Released in July 2008; adds support for Windows Vista SP1 and Windows XP SP3 [1] Windows SteadyState (formerly Shared Computer Toolkit ) is a discontinued freeware tool developed by Microsoft that gives administrators enhanced options for configuring shared computers, such as hard drive protection and advanced user management.
The exceptions to this are if it is selected during installation or already in use before an upgrade, but leaving the domain will still disable the feature. Windows Media Player 6.4, which was hidden in Windows XP and came shipped with Windows 2000 and can be installed on Windows 95, Windows NT 4.0 and Windows 98, was removed.
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.
The computer can be returned to its former state quickly (in response to activity such as the user pressing a key on the keyboard). APM Suspend: Most devices are powered off, but the system state is saved. The computer can be returned to its former state, but takes a relatively long time. (Hibernation is a special form of the APM Suspend state).
