As simple as it sounds I cannot disable hibernation. I have disabled any GUI option to disable hibernation but my acer aspire one has decided to start hibernating after an hour.
When I first installed 12.04 on this machine I followed a tutorial to get get the suspend function working and I may have fiddled with hibernation settings as well. The real clanger to all this is hibernation doesn't work on my machine so if it hibernates I must hard reboot (holding down the power ky for 5 seconds) to boot up my machine
I don;t know where to look for what might be starting the hibernation, and cannot find the tutorial I used in the first place.
