If you have a PC whether desktop or laptop, do you shut it down or sleep or hibernate? What is the difference?
When you shut down, you need to save your programs before closing them. The next time you need to use it you need to wait for the boot up process.
This mode will preserve your session. You can close your lid on a laptop and it will do this. On a desktop you can choose to sleep. When you come back everything will be the way you left it. Sleep is a low-power mode. The current state will be saved in RAM. The only power drawn is to keep RAM on. It will resume where you left off when you power back on.
Hibernation mode works a little bit differently. It saves your computer’s state to the hard drive and shuts down completely. There will be no additional power drawn like sleep mode. When you power back up, the data it loaded to the disk will load back into RAM and resume where you stopped. It will take longer to resume to where you were but not as long as a regular boot up. Hibernate is the almost the same as shutting down but your work will be preserved without shutting it down.
Most laptops are set up to sleep when you close the lid. You can customize in your settings how long it be before it goes into sleep mode. In settings you can also set up your power button to put your computer into sleep mode. Laptops may be configured already to go into hibernation mode after so many hours in sleep mode.
