Vista laptop awakes from hibernation in the middle of the night !!

End June 2007 I bought a Sony Vaio laptop (TZ11MN) with Vista Business.
I have lots of problems with Vista, specially with wireless connection
(takes a lot of time before connecting, you see it connecting, disconnecting,
connecting again...) and performance (it is frustrating !).
Now I have discovered another (serious) problem: I noticed that the laptop
was being waked automatically from hibernation state (not from sleep state,
no..., from HYBERNATION state) in the middle of the night. Today I
investigated (inspecting the event log) and found out that there were entries
starting from 3:00:55 in the morning, and this for a several days in a row.
... As the mains was disconnected at night (I disconnect also my wireless at
night) I got an almost empty battery in the morning, when I noticed that the
laptop was on.
I investigated the Task Scheduler for all tasks there, and saw no task with
triggers to awake the laptop.
Then I looked into Control Panel ->Windows Update and found to my surprise
that Automatic Update was set for 3:00:00 every day ! Bingo ! It is very
coincidental that those entries in the event log start around 3:00:55 in the
morning and Automatic Update is set to run at 3:00:00 every day ! (I never
set this myself, it was set from the installation).

But what surprises me the most, is that Automatic Update (without any
warning in the configuration) awakes the laptop (this is an assumption I will
test tonight by changing automatic update to manual update) that is
completely shut down. In hibernation stand a copy of the used memory is
written to disk and the computer is shut down completely, no power usage
whatsoever. It is completely unacceptable for any Vista component (a
scheduled component or any part of the OS) to wake a computer that is in
sleep stand (unless the user specifically has stipulated so) ! If you put
your laptop in a closed bag and it is waked automatically the produced warmth
cannot dissipate and the computer can be destroyed (plastics,
electronics...). Actually I saw mention of such an event in the following
blog: http://jkontherun.blogs.com/jkontherun/2007/06/coffee_break_wa.html.

If I compare XP (installed in another laptop) with current Vista, I must say
XP is a fantastic product ! No problems connecting to the same wireless
device that is giving so much problems with Vista (a Linksys WRT54G), no
problems with performance, (almost) no problems with hibernation.

Yes, this is another problem with Microsoft's "We have control"
philosophy, albeit an unintentional one.

I would advise that you change the time to one where the machine is
likely to be opened up and maybe on the charger. If you turn updates off
you will stop normal updates but not the "Stealth" updates that
Microsoft have begun to perform. Since Microsoft don't really want to
talk about these we have no idea what time they may take place, so we
just have to "Hope" they either occur when the machine is on or else
respect the time settings for ordinary updates.

My assumption was correct: Automatic Windows update was the one awakening my
laptop from hibernation, since I changed the setting to “check for updates
but let me choose whether to download and install them†the laptop did not
awake at 3:00 in the morning like it had being doing several nights in a row.
I think Automatic Updates must have been updated itself recently to have this
feature, has I never noticed this behavior before.

How would this update setting be different – in terms of received update
contents – from the setting “Install Updates Automatically (recommended)â€.
What are those "Stealth" updates ? I never heard about them. Can you point me
to information about that ?
 
This irritating behavior can also be caused by Media Center if it tries to
update the program guide. It needs to be fixed urgently, since it presents a
potential fire risk if the laptop was put away e.g. in a carry case. James

It is indeed very wise to use hibernation before storing or moving a portable
PC, and that is the reason why I started this thread in the first place,
because, as I have discovered, *Windows Automatic Update* – the king of the
hidden timed events (is not mentioned in the Task Scheduler list in my Vista
laptop) – was the one timed event that was interrupting my laptop from
*HIBERNATION* !
