I have searched the forums and found many threads about similar topics, but nothing quite like my problem:

Having heard other users posting that while having your Time machine disk plugged in the computer will not automatically sleep. I have my computer set to go to sleep after inactivity lasting 7 minutes, but nothing happens. If this is because of Time Machine, is there a fix? My computer does sleep when I select Apple menu> Sleep, or pressing the power button and then clicking Sleep, so it is not that my system doesn't sleep.

This is a MacBook (May 2007), see signature below.
 
anyone with a solution to this?
is it some plist somewhere that prevents the mb to go to sleep?
