Default Finding process that prevents screen blanking

I have my power saver set to blank the screen after some time. Right
after a boot, it works fine. Some time later it stops blanking. I have
tried to figure out what is doing it will little success, other than
just rebooting the machine. I am sure I am starting something in my
normal course of use that is doing this.
I can't find any process in particular that I can stop that makes it
better and eventually I break so much stuff I have to boot anyway.
Any tips?

I don't know if this POWERCFG switch is available in XP, so try typing below
from the command prompt.

powercfg -requests

I'll list either applications and/or drivers which prevent the display or
system from entering power saving mode. The output would look like below.

DISPLAY:
None.

SYSTEM:
[DRIVER] ú
[DRIVER] ú
[DRIVER] ú
[DRIVER] ú
[DRIVER] ú
[DRIVER] Legacy Kernel Caller
[DRIVER] ú

AWAYMODE:
None.

What you should look is the lines between the "DISPLAY:" and "SYSTEM:". In
above example output, there's none. Note that it only list those which are
actively preventing power saving mode.

Most non-utility applications that prevent power saving mode won't be
detected by POWERCFG. There's no way to know which application that do it
without a system debugging tool and knowledge about Windows programming.
There may be a utility designed for this purpose, but I haven't tried to
search for it.

POWERCFG is there but "requests" is not an option on that version.

Right click desktop, properties, screensaver. Set it to blank
after, say 15 minutes.


It is set and works OK for a while after a fresh boot.
Sometimes it goes days and still blanks on schedule. Other times a few
hours in, it stops blanking. I can't seem to develop any pattern about
what is stopping that from happening. Booting always brings it back to
blanking on schedule.
The only thing I am worried about is that maybe there is some malware
running.


Well, I like CodeStuff Starter to look at services and
programs that are running in the background.

http://www.majorgeeks.com/files/details/starter.html
I use the portable version.

Compare what is running when the screensaver is working OK to
what is running when it does not. Quite a few programs have "prevent
screensaver from working" in their options. Maybe you closed one down
but left the module in memory.
You did say "any tips"

Warning CodeStuff Starter is a powerful tool. Careful with
which services/programs you mess around with.

Modern screens use so little power that you are not really
saving much.

I have tried comparing the task manager list when it os working and
not and nothing stands out. This may be a svchost thing since there
are lots of them each time.
