Power off - Sleep or Hybernate when closing the lid - which options do we have?

Recommended Posts

good day dear php-community,


today-topic: Power off - Sleep or Hybernate when closing the lid - which options do we have?


well i allways thought that we are able to choose what happens when we close the lid of our laptops once our work is over. i allways thought that we have many options:

Closing the lid can result in the linux system is shutting down, sleeping or hibernating.  I allways thought that we control the behavior and decide what we want tod do, once we close the lid.guess that we can sum it up - that there are particularly 3 methods for powering down in linux.

- making the PC going to sleep
- making the system hibernating the PC
- turn it off completely - in other words - shooting down the system completely

The Sleep options consumes only a very little power :: With this - the pc can wake up after sleep. 

security-levels: Chances of losing your work due to battery draining are minimized to zero in the Sleep mode as the OS automatically saves all your 
work before turning off your PC when the battery is too low. This so called sleep mode is often brought into use when a person is away from his desk just for a short while. 

more options: We have even more options - eg. the so called the Hibernate option, 

to compare it with other methods and options: in comparison to the Sleep mode uses even less power (it is a true power - saver) and lands us at the same position where we last left off. That is brilliant - isnt it!? The so called Hibernate-option however, should be used when we are aware that we won’t use our laptop for an extended period. There are differences between the different modes:  we have Hibernate or Shutdown and here to see the difference between Sleep & Hibernate.

question: is it possible to push the laptop to any of the three power states described above, by simply closing the lid of the machine?
