I tried searching launchpad, as you suggested (although I do not really 
understand what that is all about and what is going on there).
Apparently this IS a bug ...
https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/875546
"Bug Description
Ever since I did a fresh install of Natty (and subsequently Oneiric) I 
have not been able to wake my desktop from suspend to RAM. Sleep 
previously worked on Maverick with no problems.

The computer will go into sleep mode after selecting suspend, but when I 
try to wake it by pushing the power button, the monitor remains shut 
down (not even a blank screen) and the USB keyboard and mouse are both 
unresponsive. The desktop tower itself is powered on though."

"Status changed to 'Confirmed' because the bug affects multiple users."

As far as I can tell, a solution has not been proposed (but maybe I am 
not looking in the right places)
My computer - very old, for experimenting with Ubuntu - Hitachi, Flora 
(I don't know the precise model name)
AND I don't know where to look for something that would be in Windows 
"system properties"
Ubuntu 12.04 English version (Japanese language enabled) with all 
updates installed (clean install last week)
Does this information help?
