Can it be that the laptop has some power management policy defined
that stops the disk after some time, and Emacs waits until it spins
up?

If the files are local, there's nothing for Emacs to check on the
network, I think.  But if you can install some sniffer, like windump,
and see what is the traffic on the network during these delays, that
might unlock the mystery.

But you said that in your case, setting w32-get-true-file-attributes
to nil didn't help, didn't you?

How about this setting:

  (setq vc-handled-backends nil)

Put it in your .emacs, restart Emacs and see if the delays go away.
