Oh, sorry. I would like to claim that a loss of consciousness indeed
might pass unnoticed by the "subject" in this case. I should have
stated that.

For example, let's say that all of Monday except the last seven minutes
is a genuine computation on some genuine computer, and that in
executing Monday, the computer goes through N states per minute.
Let's further say that during the last seven minutes, each of the 7*N
states was not computed at all, but was loaded from completely
random states somebody produced from a random number
generator BUT JUST SO HAPPENED by sheer chance to be
identical to the 7*N states that would have been computed.

Then I claim

(1) during those 7 minutes the subject, i.e. the person, was
      not conscious (or alive)
(2) later he would have absolutely no way of knowing that
     those 7 minutes were in any way different, unless he
     learned about it indirectly some time later.

For, to the person, it might just as well have been, I claim,
the same as if he stopped being conscious at 23:23 on Monday,
and then at 12:00:00 am on Tuesday morning had some memories
of those 7 minutes added, memories that would be identical to
the memories he would have obtained had he been calculated
the whole time.
