You have been subscribed to a public bug: Hello!
I've scanned many bug topics here for my problem, but none of the things, for example http://ubuntuforums.org/showthread.php?t=1978290 , I tried have solved my problem. So my problem is that my Thinkpad T530 won't suspend anymore at all -- what happens is just a flash of screen and return to the previous view. It seems that there could be something that automatically wakes the laptop at an instant later. I have suspected it might be related to mDNS activity but since I don't have any knowledge about Ubuntu, I'd better not speculate. I couldn't find my Ubuntu package name from this apt-cache file...
