b101 Posted April 12, 2016 Share Posted April 12, 2016 hi folks, i just installed El Cap on my ProBook 440 G3 (Skylake). When I stay long enough idle sleep mode activates.. at least the display turns off, but i hear no change regarding HDD and Fan speed ( I can literally hear no change) and after a while in this "sleep" mode my Laptop just reboots - and whats even worse ! After that it gives me some stupid message about my Battery being empty and resets my BIOS settings. This only happens in "sleep" tho. Anyone know of this problem?I've seen a couple of posts regarding hibernatemode but they all change it to 21 or 29 - I can't apply this command. As soon as I enter "sudo pmset -a hibernatemode 21" (or 29) my terminal output says: Usage: pmset <options> See pmset(1) for details: 'man pmset'well, when of course I have looked the manpage up and it says 0 3 25 are possible (no big surprise here LOL) so how should I set it to 21 or 29 ?? and will this fix the sleep mode / restart problem anyway?? best regards Link to comment Share on other sites More sharing options...

b101 Posted April 13, 2016 Author Share Posted April 13, 2016 I think I read that RehabMan said that hibernation is not working on Hackintosh - no I dont know if he means only on Laptops oder Desktops or in general.. Even if hibernate is not possible - there must be a way of fixing the sleep mode and stopping the laptop from restarting. Link to comment Share on other sites More sharing options...
Tetonne Posted July 30, 2016 Share Posted July 30, 2016 it's use to work with 29 with this http://www.insanelym...and-how-to-use/ but it doesn't anymore I found this For OS X El Capitan, you'll need modify the com.apple.PowerManagement.plist. Type this in Finder > Go > Go to folder: /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist And find the Hibernate Mode in both section and put the value that you want. source : #3 doesn't work either (it reboot ) Link to comment Share on other sites More sharing options...
