Windows XP not entering standby mode

[Guest]

I am trying to diagnose why a computer will not go into Standby mode.

If i set the time for stanby to a couple of minutes, it will quite happily
go into standby, and then awake without any problems. However, if I make the
time for Standby 30 minutes, it never goes into Standby.

I've tried simply re-booting the computer and leaving it sitting at the
login screen, but even from here without any user logged on, it will only go
into Standby mode if the time is short.

Any ideas on how to diagnose where the problem is would be greatly appreciated

Cheers
Tom

Something is running in less than 30 minutes which prevents it from reaching
that time.

Is it a desktop or a laptop? You need to look into Power Options from
Control Panel.

it is a desktop computer. All of the Power option settings are correct and
working. If I set the time to go into standby to less than 5 minutes .. it
works fine. However, when I set it to a more reasonable 30 minutes it never
happens.

I am trying to get this to work, as we have over 600 identical computers in
pools for students to use, and having them sitting there waiting for someone
to log on 24 hours a day wastes a lot of energy

Are you sure you want the desktop to go into standby? Hibernation is
more appropriate for desktops.

Also, are you setting times for Monitor and Hard Disks to switch off
after specied time?

You also need to set the time for hibernation (the last item on that
tab)

only Tommy:

I did exactly as you, and got the same results.

But the screensaver and monitor shuts down at the correct intervals, namely
20 minutes, and 30 minutes respectively. It appears these react to keyboard
and mouse inputs.

I have 4 PC's on a home network that is often left on during the day, and
overnight, and the wife was complaining about electric bills exceeding
$140.00/month. What I did was got hold of freeware that I program in the
Windows Scheduler to hibernate it at a certain time at night, at 9:30 PM.

But checking further, it appears that there's a threshold of CPU activity
above which hibernation or standby will not occur. I watched on the
taskmanager, and it appears that even when there's nothing going on, CPU
activity ranges from 4% up to 16% for service running. I don't know where the
threshold is set, but it seems you wouldn't want the PC to hibernate when
running a large job.

I didn't want to start a project analyzing services.

I did locate a program that you can select a time interval, and CPU
threshold, and program it to set the PC to standby or hibernate. So having
CPU activity below 17% for 45 minutes may work for me. I have since lost
track of this program I found, and try to locate it myself. I was
concentrating on getting FREEWARE that works at the time.

For the home network, programming PC hibernation gets the PC to sleep at a
set time. I also set to hibernate in the power options, but it never seems
to work, except as you say, a time interval of 5 minutes is used.

I already cut the electric bill to below $80.00 and the wife wanted me to
get going on something else more useful.
