Usefulness
When using sleep mode, you can turn off the computer, and make sure all the work back when (including not enough time to save or close the program and documentation) will be fully restored to exactly the state left off. The contents of memory are saved on disk, monitor and hard drive will shut down, but also saves energy, reduces the loss of the computer. In general, make the time to lift the computer time required for hibernation state needed to wait longer than the lift, but consumes less power sleep state. If you work frequently interrupted, as some secretarial career, often while you want to have to answer the call while the computer processing, etc., you can consider to _set_ the computer after a specified number of minutes after entering the automatic sleep mode. Sleep mode will save all the contents of memory to the hard drive, turn off the monitor and hard drive, and then turn off the computer.

When you enable hibernation, the system prompts "Energy Policy Manager unable to retain Enable Hibernation", "Access Denied." Workaround: Remove hiberfil.sys file C root directory, and then re-enabled. (_Delete_: In the "Start" - "Search" - "files and folders" - Enter the "All or part of the file name" box "hiberfil.sys" in the "Look in" box, _select_ "c. disk "and click" Search Tools "If you do not find the file, then." "-" Folder Options "-" View "- the" Hide protected operating system files "option in front of the box in the "√" removed, then re-search, no accident, then, should be able to find the "hiberfil.sys") 6 End sleep function Re-enter the system and boot as: power, start, but the system started soon.

What is the difference between sleep and standby
In Windows XP features include power "sleep" and "standby." "Sleep" to save a copy of your desktop and all open files and document image, and then turn off the computer. When power is turned on, according to the original file and the document will look like when left open on the desktop. "Standby" function of the hardware components used in cutting power, thereby reducing the power consumption of the computer. "Standby" to cut off peripheral devices, monitors and even the hard drive's power, but it will keep your computer's memory power, so as not to lose work data. When your computer into hibernation, the contents of memory will be saved to the hard disk. When you wake the computer, all programs and open documents before entering hibernation are restored to the desktop. This allows greatly improved startup and shutdown speed.
