Suspension not working

I cannot put my pinebook 1080 in suspension.

I read this thread https://forum.pine64.org/showthread.php?tid=6859 but I cannot understand how this will be applicable to my distribution.

Any help?

Suspension does not really suspend. It puts the device in a sort of sleep mode.

The best way to use this sleep mode, is with lid close and open.
It's pretty much just turning off the screen.

If you use the suspend function in other ways, you have to turn the device off by holding the power button, then turn it on again, which would be a fresh boot.

So anything to configure?

And what is useful the tlp daemon?
