I test two times as commented in [1] and I can see that this problem don't hapen if, before shutdown, I close LCD Display (activing LID to hibernate).
[1] <http://bugzilla.kernel.org/show_bug.cgi?id=10797#c1>
So, to shutdown laptop with no battery change, is necessary:
1) Active LID (closing LCD Display). With this, my laptop will hibernate, so is necessary wake-up again. 2) Shutdown
