There are several ways to put your computer to sleep using the command line or command prompt. One way is to use the command rundll32.exe powrprof.dll,SetSuspendState 0,1,0. However, this command may not work as expected and may put your computer into hibernation mode instead of sleep mode. Another way is to use the NirCmd tool, which has a standby command that can be used to put the computer to sleep. Additionally, you can use the Sysinternals PsShutdown tool with the -x option to put your computer into sleep mode. It is important to note that the specific methods and commands may vary depending on your operating system version and your computer's settings.

Windows 11 Pro 22H2: use the command 'rundll32.exe powrprof.dll,SetSuspendState 0,1,0'
To enter sleep mode on Windows 11 Pro 22H2, you can use the command line. This can be useful if you want to put your computer to sleep or hibernate quickly and easily.
Firstly, open the Start Menu and find the Command Prompt by typing 'cmd.exe' in the search bar. Right-click on it and choose "Run as administrator" to open it with administrative privileges.
Now, to put your computer into sleep mode, type the following command:
Rundll32.exe powrprof.dll,SetSuspendState 0,1,0
Then hit Enter to execute the command. This will initiate the sleep mode on your computer.
Note that this command may result in hibernation instead of sleep if hibernation is turned on. To ensure your computer enters sleep mode, you can disable hibernation by opening an Admin command prompt and typing:
Powercfg -h off
By following these steps, you can conveniently put your Windows 11 Pro 22H2 device into sleep mode using the command line.

Disable hibernation: use the command 'powercfg -h off'
To enter sleep mode using the command line, you must first disable hibernation. This is because hibernation bypasses sleep mode and immediately saves session data to a hidden file named Hiberfil.sys. Therefore, if your computer is in sleep mode and the power goes out, the session data will be lost.
To disable hibernation, use the command powercfg -h off. This command will prevent your computer from entering hibernation mode, which can be useful if you want to ensure that your session data is always saved in the event of a power outage.
- Open the Start Menu and search for "cmd".
- Right-click on Command Prompt and choose "Run as administrator".
- Type the following command: powercfg.exe -h off
- Press Enter to execute the command.
- Type "exit" and press Enter to close the Command Prompt window.
Disabling hibernation will not corrupt your Windows files or operating system files. However, it is important to note that if your computer is in sleep mode and the power goes out, you may lose any unsaved data or files that were open, such as Microsoft Word documents or photos. Therefore, it is recommended to save your work and shut down your computer properly to avoid any data loss.

Linux: use the 'sleep' command
The 'sleep' command in Linux is a versatile tool for introducing delays in script execution. Its simple syntax, defined as 'sleep NUMBER [SUFFIX]', allows users to specify time durations in seconds or use suffixes to denote minutes, hours, or days. For example, 'sleep 6' will pause the script for 6 seconds, while 'sleep 3m' will pause it for 3 minutes.
The Sleep command is like a pause button for your computer. You can type "sleep N," with N being a number (either a whole number or a number with decimals), and your computer will wait for that many seconds before proceeding to the next task in a script. This is especially useful when you need extended periods of delay, and using suffixes makes the command more human-readable. For instance, 'sleep 3h' will pause the execution for 3 hours. You can even use decimal values to specify fractional seconds, such as 'sleep 3.5s' for a 3.5-second delay.
The Sleep command can be interrupted using signals. For example, pressing 'Ctrl+C' sends a SIGINT signal, terminating the sleep. This allows users to gracefully interrupt the sleep duration and proceed with other actions.
The sleep command is designed to work in combination with other Linux commands. For instance, you can use it to schedule the system to play an mp3 file after a specified time. Here's an example:
Bash
Sleep 8h && mplayer wake-up.mp3
In this case, the system will play the file 'wake-up.mp3' after an 8-hour delay. The sleep command is also useful for enforcing time between the execution of two commands. For example:
Bash
#!/bin/bash
SLEEP_INTERVAL="30"
CURRENT_TIME=$(date +"%T")
Echo "Time before sleep: ${CURRENT_TIME}"
Echo "Sleeping for ${SLEEP_INTERVAL} seconds"
Sleep ${SLEEP_INTERVAL}
CURRENT_TIME=$(date +"%T")
Echo "Time after sleep: ${CURRENT_TIME}"
In this script, the system displays the time before and after a 30-second sleep duration, demonstrating the use of the sleep command to pause execution.

Linux: interrupt the sleep command using 'Ctrl+C'
The 'sleep' command in Linux is a versatile tool that allows users to introduce delays in script execution. The syntax is simple and allows users to specify time durations in seconds or use suffixes to denote minutes, hours, or days. For example, using the 'm' suffix denotes minutes, so the command "sleep 3m" will pause execution for 3 minutes. Similarly, 'h' denotes hours, so "sleep 3h" will pause execution for 3 hours.
The sleep command can be interrupted using signals. Pressing 'Ctrl+C' sends a SIGINT signal, which terminates the sleep command. This allows users to gracefully interrupt the sleep duration and proceed with other actions. For example, if you had a sleep command set for 12 hours, you could press 'Ctrl+C' after a few minutes to end the sleep early.
The ability to interrupt the sleep command using 'Ctrl+C' is particularly useful when you need to delay a script for a long duration but want the flexibility to end the delay early if needed. Without this interruption feature, users would have to wait for the specified duration to end before they could proceed with other actions.
The sleep command in Linux, along with its interrupt feature, showcases the flexibility and control that the command-line interface offers. It is a valuable tool for users who prefer the efficiency and customisation of the command line over graphical user interfaces.

Windows: install PsShutdown from Microsoft
PsShutdown is a command-line utility that can be used to shut down or reboot a local or remote computer. It is part of the PsTools suite offered by Sysinternals. PsShutdown provides more flexibility and power than the Microsoft Shutdown tools. It works on Windows NT 4.0 and later, although certain options require Windows 2000 or higher.
Unlike other shutdown utilities, PsShutdown does not require manual installation of client software. To install PsShutdown, simply copy the PsShutdown file to your executable path. You can then run it by typing "psshutdown" followed by various command-line options.
For example, to initiate a system reboot at 10 pm, you can use the command:
Psshutdown -m "The system requires a reboot to complete hotfix installation" -t 22:00 -r
Here, the "-m" switch allows you to specify a message, "-t" sets the time for the operation, and "-r" indicates a reboot.
Additionally, PsShutdown offers features like aborting an imminent shutdown with the "-a" switch, locking the console with the "-l" switch, and logging off a user with the "-l" switch.
It's important to note that when using PsShutdown on remote computers, you must enable file sharing and ensure the Admin$ share is accessible through the Common Internet File System (CIFS)/Server Message Block (SMB) and Remote Procedure Call (RPC) TCP/IP ports.
