Watts are the right unit to measure power.
What we really want to know, though, is how many joules of energy they wasted
My workplace requires all computers used there to have anti-virus installed, which is why I have antivirus on this machine despite it running Linux. (It even found something, once: a decompression bomb that I was looking at for fun.)
Something similar to the summary happens to me occasionally (although it isn't obviously linked to suspend or lid closing).
I'm using a (custom-patched) Unity, so I fix the problem with control-alt-f1, log in, DISPLAY=:0 unity &. (The DISPLAY=:0 is required because most window managers don't know how to run in a terminal.) If you're using a different window manager, just swap out its name.)
You don't even lose any work, but all the windows do end up collapsing onto the same virtual desktop.
For anyone interested reading this discussion, I may as well say what the proof actually is, because it's shorter than typical explanations of how easy it is.
Suppose there are only a finite number of prime numbers. That means you can produce a complete List Of All Primes. Multiply them all together, add 1. This number has no prime factors (by definition; none of the primes on our List Of All Primes divide into it), which means it must be prime itself, but it's way bigger than anything on the list so it can't be. This is a contradiction, so the assumption that there are only finitely many primes must be wrong.
(And indeed, this is used as a standard example of proof technique.)

It refuses to serve text/plain, even if you ask for it specifically. (Compare http://en.wikipedia.org/w/index.php?title=Main_Page&action=raw&ctype=text/css, which it'll serve quite happily.)
