Windows 7 Waking Up Laptop

[BillW50]

I normally don't leave this laptop in the dock when hibernating and I
don't often have a battery installed (it actually holds two). So there
is no way when I hibernate it through BattStat 0.99b, that the machine
could self power up. But last night I left it in the dock with power.
And it woke up 58 minutes after I put it into hibernation mode.

The system time has changed to ‎2011‎-‎12‎-‎11T03:17:14.500000000Z from
‎2011‎-‎12‎-‎11T02:19:39.999025300Z.

This is the event that seemed to start the wake up. The rest of them
seem to suggest that it was looking to get on the Internet for some
reason. I don't understand the system time change event since this was
the time it was sitting in hibernation. So of course it needs the system
time change, but why would this event cause the laptop to wake up?

It looks like the system is set to check for the correct time over the
internet. It has to compare its time/date with the correct one for your
time-zone, right? It can't do that without waking up. Keep in mind that
"hibernate" does not turn off the system, merely sets it to minimal
activity.

Windows does a lot of system maintenance in the background, by default.
I don't know how to find out what all it does, nor how to turn it off,
maybe someone else can help you with that. I doubt that it would be
advisable to do so, however.

PS: if the clock is out by over an hour, something is seriously wrong. I
suspect that your habit of taking out the battery is messing with the clock.

Thanks Wolf. As far as I know, hibernation under Windows 7 does both
hibernate and standby in one shot. If it never loses power, well it acts
just like standby. If the power is removed, then it reboots using the
hibernation file. Somebody correct me if I am wrong, but that is how it
looks here.

The reason why the system clock was off by 58 minutes was that it was
hibernating for 58 minutes. So that makes perfect sense to me and the
RTC (which is running from the CMOS battery) was never off.

So following the event log, the first thing happened was the system
clock got updated. This happened when the laptop woke up on its own.
There is a power event about 6 events later (all seconds after powering
up). And it stated like power was enabled and the reason was unknown
(big help there).

I have five other M465 too. But they all have XP installed and no
Windows 7. And they don't wake up on their own. The XP ones does have
third party software to keep the time correct. Although it does nothing
at all if it is hibernating/standby or has no Internet connection. I
never installed the same software on this Windows 7 machine yet.

Here is what normally happens on these machines. If you press the power
button and turn them on. Then walk out of the room to make coffee or
something and come back after 5 minutes or so, it goes and shuts down on
its own. Although if you do anything at all, press a key, move a mouse,
etc. it stays on as long as you would like.

I assume this is a safety feature to shut down if it accidentally woken
up. I didn't allow this to happen last night. I just used hibernation
again and then removed the power and went to bed.

I do have two USB TV tuners that I run with these things too. And if a
sheldule is set to record something, they will wake and record and then
do what you set the schedule to do after the recording. They will only
wake if they are either in standby or hibernation. If shut down, they
will miss the schedule. And I never seen this software wake one of them
up if there wasn't a schedule set to wake them up.

And I seem to remember this machine doing this once Windows 7 was first
installed. Before anything else was installed at all.
