msingh Posted January 4, 2009 Share Posted January 4, 2009 I have a nearly perfect install of iDeneb 10.5.5 on this Acer Travelmate 2420 - nearly perfect, because hibernate (or any type of sleep) does not work. I have tried setting hibernatemode various settings (3 and 7): $ pmset -g Active Profiles: Battery Power -1 AC Power -1* Currently in use: sleep 0 displaysleep 5 powerbutton 1 hibernatefile /var/vm/sleepimage hibernatemode 3 disksleep 10 ttyskeepawake 1 I have PC EFI v9 + chameleon 1.0.12. I cannot patch my DSDT (using fassl) : http://forum.insanelymac.com/index.php?sho...00#entry1024595 I have tried to generate dsdt.aml using the -f flag but that has not helped (or hurt). I need to get hibernation working. Its more important than any updates (any attempts to upgrade to 10.5.6 end in a hosed system anyways for me). When I choose Sleep (or the Deep Sleep widget or Fn+F4), I get a poweroff with a single clicking sound (the switch off takes maybe 2 seconds). I can confirm that a file /var/vm/sleepimage exists but I doubt that is it is being generate during the hibernate. As far as I can tell, I cannot find any messages about any hibernate attempt in /var/log/system.log. On powering on after such a "hibernate", I get a Sleep image has garbage error and the boot proceeds as if I had never attempted to hibernate. Since this is a laptop, getting hibernate to work is essential. Can anyone please help me diagnose the cause of this and hopefully fix it ?

I would like to add that this laptop previously ran Linux and had absolutely no issues hibernating. So, there is no limitation on the hardware side.
