Looks normal.

Maybe a 
      sleep 1 
will help with your issue (or more secs...)

               This only has elements when the lid is closed, so the do 
               block will only be exexuted, if the lid is closed.

          Therefor this is totally pointless, because we only come to 
          this point if the lid is closed and thus $i is always == "closed"

This whole block will never ever be reached, so you can easily erase it.

You should test if your Desktop Environment does the suspending for you. 
Then you have to tweak there, to get the behaviour you want.
