Has anyone managed to configure 'hibernate' after x minutes of sleep? I'm able to map the physical power button to hibernate which works awesome. But the ideal solution would be to hibernate after 30 mins of connected standby/sleep for the best battery life. Could care less about potential wear on the disk. I've not been successful, wake on timers, hibernate after X minutes options all seem to do nothing. Is there a trick to this? or not technically possible?
