On a Linux system, the suspend and hibernate functionality allows you to put the system into a low-power state when it is not in use. Suspend will save the current state of the system in memory and power off most of the hardware, while hibernate will save the current state of the system to disk and power off the hardware completely.
To use the suspend or hibernate functionality on a Linux system, you will need to ensure that your hardware and software support these features. Here are a few things to consider:
Hardware support:
Your hardware must support suspend or hibernate in order for the functionality to work. Most modern hardware should support these features, but it is always a good idea to check the documentation for your hardware to ensure that it is compatible.
Software support:
Your Linux distribution must have the necessary software support for suspend and hibernate. Most modern Linux distributions include the necessary support by default, but it is always a good idea to check the documentation for your distribution to ensure that it is compatible.
Kernel support:
The Linux kernel must have the necessary support for suspend and hibernate. Most modern kernels include the necessary support by default, but it is always a good idea to check the documentation for your kernel to ensure that it is compatible.
If your hardware, software, and kernel support suspend and hibernate, you should be able to use these features on your Linux system. To use these features, you can use the systemctl command or the pm-suspend or pm-hibernate commands, depending on your system. Consult the documentation for your Linux distribution for more information on how to use these features.
