The Sleep tool lets you put your computer into a power-saving mode and more through the Command Line.

By default, when using Sleep, the computer enters "suspend" mode, a low-power state designed to save energy while allowing for a quick return to full operation. In this mode, the current state of the operating system, including open applications and documents, is stored in the computer's RAM (Random Access Memory). This RAM remains powered, ensuring all information is retained and can be accessed immediately upon awakening the computer.

Advantages
One of the significant advantages of suspend mode is the speed with which the device can be reactivated. Users can quickly resume their work by simply pressing any key on the keyboard or moving the mouse, eliminating the need for a lengthy boot-up process. This feature is particularly beneficial for those who need to take short breaks or are in situations where they quickly need to switch their attention back to their tasks. Overall, suspend mode strikes a balance between energy efficiency and user convenience.

Hibernate
Sleep also has the capability to initiate "hibernate" mode on the computer by utilizing the /h switch in its command line. When this mode is activated, the entire state of the operating system, including all open applications and active processes, is saved to the hard drive. This process effectively captures the current session, allowing users to resume their work precisely where they left off.

It's important to note that the wake-up time from hibernation is significantly longer compared to "suspend" mode, as the system must retrieve the saved state from the hard drive and restore it to RAM. However, one of the key advantages of hibernation is its energy efficiency; while in this state, the computer consumes almost no electricity since the RAM does not need to be powered to maintain the stored data.

Wake Up
When you want to resume the computing session, you can simply press the power button, which triggers the computer to wake from hibernation and reloads the saved session, allowing for a seamless transition back to work.

Usage:

SLEEP [/f] [/h] [/m] [/nologo] [/nr] [/ns] [/r] [/w#]


Switches:

/f Force the computer to sleep. Otherwise, any running application will be able to prevent the computer from sleeping if it so chooses.

/h Hibernate instead of suspending. Go here for an explanation of how to enable hibernation.

/m Turn the monitor off.

/nologo Suppress the title banner.

/nr Don't report the current power status.

/ns Prevent entering sleep mode. The power status will still be reported.

/r Reboot instead of suspending.

/w# Wait for the specified number of milliseconds before sleeping/hibernating/rebooting.

For example, you can make your PC enter hibernation mode instead of sleep mode by using the /h command. Hibernation saves power because the computer does not use any RAM. To wake up your PC, you need to press the power button. Sleep will report the current power status in the console window, but you can disable this with /nr. Use /ns to prevent entering sleep mode while still reporting the power status. To reboot the PC, use /r. Set a delay before termination with /w#.
