I keep trying to turn the LCD on my W500 off via Fn + F3.

Problem is, while it initially shuts off like it should it keeps coming back on after a few minutes. There is nothing going on that would normally 'wake up' the screen (including minimizing any active apps & turning off the wireless mouse).

any ideas why it keeps waking up?

i've seen similar behavior on my winxp machines, but haven't noticed it since moving to win7
are you running xp?

Yep, Win XP SP3.

Interesting that it isn't a consistent, set period before it 'wakes up'. Sometimes within a couple/three minute. Other times it can be as much as 10-15 minutes.

Think it's O/S related?

not sure, but i don't see the behavior on win7.
if you boot to safe mode, does it still happen?

Do you lock your screen before turning it off, or do you just turn it off? I had a similar issue, and I solved it by going to the welcome screen before hitting FnF3 - I don't know if this is applicable for you, but it works perfectly for me

I'm going to venture a guess that it's some software - quite likely AV - checking out the surroundings...
