Have you tried Apple menu>System Preferences>Energy Saver? Disable hard-drive sleep and display/computer sleep?

I want to turn it off. On my last laptop with 16gb ram it gave me extra space on ssd.

From my archives, I found this:
===========================
First, disable hibernation mode :
sudo pmset -a hibernatemode 0

delete /private/var/vm/sleepimage :
sudo rm /private/var/vm/sleepimage

create an empty file and name it 'sleepimage' :
sudo touch /private/var/vm/sleepimage

change this flag to immuable:
sudo chflags uchg /private/var/vm/sleepimage

Now, OS X won't be able to rebuilt over your sleepimage file since it is locked.

Hello, Thank you for this tip. It worked for me. Now I want to go back to the standard.

Is it possible to know the workaround to enable the default settings ?

thanks !

If you followed Fishrrman’s suggestion fully, then you should proceed as follows. First, you need to restore the sleep image to its original state with these commands:

sudo chflags nouchg /var/vm/sleepimage
sudo chown root:wheel /var/vm/sleepimage
sudo chmod 1600 /var/vm/sleepimage

To verify, when you type this command:

ls -lOh /var/vm/sleepimage

You should get this result:

-rw------T  1 root  wheel  -  4.0G Aug 23 15:01 /var/vm/sleepimage

Then you need to reset the hibernation mode to its system default:

sudo pmset -a hibernatemode 3

You may have to reboot.
