I have this problem. I can put my system to sleep, close the lid and it will have no problem waking up. But if I just close the lid it will not wake up after reopening the lid. The powerbutton lights up, but otherwise it won't react to anything. I have to do a hard shutdown by holding the powerbutton. After starting the system up I have no errors. Anybody knows how to change this behavior.
My setting are: System Settings > Power Management > Energy Saving > Button Event Handling > When laptop lid closes, Suspend. So in my mind the settings are correct. When I close the lid it should go to bed ( put things in Ram ) and sleep. I know it is not hard to make it sleep before closing the lid, but just closing the lid should work, right? Your thoughts about this please.
