I tried the Kernel PPA but it didn't correct the problem. As asked I've moved back onto the Ubuntu 13.04 release, now at 3.8.0-26-generic, but after rebooting and going into Suspend, it acted the same way when I tried to wake up (<shift> would wake up the computer as the fan was running, but the monitor would stay in sleep mode and nothing else would happen).
