If the computer is starting from a powered off state (hibernate), there are
most likely "Wake..." settings in BIOS that are enabled: wake on LAN, wake
on Ring, wake on timer, etc. If there are no wake settings in BIOS, the
system power supply or power switch may be faulty.

The standby problem may or may not be related. There are many programs that
can be configured to perform tasks if the machine is idle after x number of
minutes. Check settings in programs that are normally left running. Also,
check the configuration of each task listed in Scheduled Tasks.

Do you know if these same laws regarding power supplies etc.. are applicable
to laptop computers with ACPI whatnot?

There are no BIOS settings on this thing. Everything seems to be controlled
by XP.

Checked and rechecked one million switches, I am totally baffled.

OK after little more testing, I have more feedback.

I switched off my PC (via shutdown) and the thing didn't start up again
until I switched it back on manually.

But if I Hibernate or Standby it, it switches on automatically after approx
20-30 mins. There are no wake on LAN options set. The PC has a builtin LAN
and also Wireless. The LAN is set to switch off in Device Manager and the
Wireless is set to Maximum power save mode. Both options *don't* appear to
be the culprit.

The PC is a Sony laptop with XP Home OEM.

Is there a utility I can use to troubleshoot my problem here? How can I use
Event Viewer more effectively?

Thanks, I appreciate the input.

Some systems have varying levels of "sleep." For example, a trickle of
power that maintains data in RAM but the rest of the system is effectively
"off." Not really "hibernate" in the usual sense of the word and referred
to as "deep sleep" in some setups.

My suggestion is to dig deeper in the power management documentation for
this laptop. You may also want to involve Sony tech support just in case
there is something triggering an "on" response that shouldn't be happening.

I think I may have finally rooted the problem, but am unsure how to fix it.

I have found that connecting to the net leaves my inbuilt softmodem in a
funny state when hibernating or going into standby.

I have found that if I restart my PC and go straight into Hibernate/Standby,
before connecting to the modem, then the PC is stable and does not
autoresume.

So my guess is it could be a firewall issue which leaves the modem in a
funny state when going to hibernate/standby.

I have had issues in the past when connecting using a modem via a firewall.
Sometimes it seems XP and modems weren't a match made in heaven (Redmond).

Interesting. Have you checked to see if there is an updated driver for the
modem or talked to Sony about this?

I was thinking about your problem today. Another thought that crossed my
mind is the settings in Control Panel's Power Options. You can use this to
set up the system to hibernate by "closing the lid" of a laptop. If the
latch was loose on the lid and there is a lack of clearance between the
edge of the screen and the power switch, they could bump into each other
enough to turn the system back on.

I may be reaching more than I should for an explanation to your problem but
but it does sound like the Sony laptop is not truly hibernating (power
completely off). There is either a power switch problem of some kind or
power management/hibernate is very different on a Sony than most laptops.
