Yeah, maybe no 'official click this box' type way but as we've found the settings are possible and pretty easy to invoke.

If I delete those files, will the separate Display/System sleep timers come back? Or will it just do what this button does?

No, the separate timers will not come back by deleting those files. The idea of deleting those files is it would reset any of the pmset command line options being discussed in this thread. I am not positive clicking restore defaults would do that.

It might help if you use the files from a 2012 MBA instead. I could provide you both. However, only at your own risk!

The problem I'm having with my 2013 MBP 13" is that when `Prevent computer from sleeping when display is off' is unchecked, sleep is set to 1 as seen with pmset.
This causes the system to fall asleep if there is no activity for 1 minute, even with displaysleep set to 10.

Observed behavior;
`Prevent computer from sleeping when display is off' unchecked and displaysleep 10 -> sleep 1 (system falls asleep if there is no activity for 1 minute)
`Prevent computer from sleeping when display is off' checked and displaysleep 10 -> sleep 0 (system doesn't ever sleep)

I would expect the correct behavior should be;
`Prevent computer from sleeping when display is off' unchecked and displaysleep 10 -> sleep 10 (system falls asleep if there is no activity for 10 minutes)
`Prevent computer from sleeping when display is off' checked and displaysleep 10 -> sleep 0 (system doesn't ever sleep)

It does help to set the sleep timer to zero with:
Quote:
pmset sleep 0
the display will go blank, but the MBA will still download files or compile a project, whatever.

Ok. I did a little more digging. If you want the old behaviour back, simply do the following: Open System Preferences and set the display timeout to 5 minutes (or whatever you prefer). Then, set the sleep timeout to 30 minutes: sudo pmset sleep 30. Be sure to do this both when connected to ac and on battery.

Put Screen to Sleep

There currently is NO option to have the display blank out while the computer is still working - in order to save energy. You can't even do that with a screen saver anymore because there is no blank screen saver .

Try Control + Shift + power button

This puts the screen to sleep.

Hey guys! I have same problem, I bought my MBA 3 weeks ago, and after 5 days screen started to shut off, it happens almost every 7 or 8 hours. I think its apple's fault, as I saw many people having this problem.

Thanks for this! Exactly what I was looking for.
