Activare functie sleep in windows 7

If you don?t see the Sleep option or the Hibernate option, it may be for one of the following reasons:

Your video card may not support the Sleep mode. Refer to the documentation for your video card. You can also update the driver.
If you don?t have administrative access on the computer, you may have to refer to the administrator to change the option.
The power-saving modes in Windows are turned on and off in your computer?s BIOS (basic input/output system). To turn on these modes, restart your computer and then enter the BIOS setup program. The key for accessing BIOS differs for each computer manufacturer. Instructions for accessing BIOS generally displays on the screen as the computer boots. For more information, see your computer?s documentation or check the website for your computer?s manufacturer.
If you don?t see the Hibernate option, the Hybrid Sleep option is mostly likely enabled. We will explain how to enable and disable the Hybrid Sleep mode later in this article.
