ACPI only works for certain settings.. why?

That is to say if I set my STANDBY to 25 minutes, the machine will do
just that.. go on standby after 25 mins +/- but if I go beyond 25
minutes the machine continues to run. In fact anything above 25 and it
won't go on standby at all.

The machine is a Gateway with XP Pro installed on it. The Gateway
Green power management program has been removed. There are no settings
in the BIOS that pertain to system standby at all.

Thank you.

Bet you did not install SP1 yet. That will fix the problem.

Do you have 'content indexing service' enabled? This (and also some
prefetch deframentation, and maybe other stuff) will run if WinXP thinks
the machine is idle .. I guess it could stop the machine ever getting
idle enough to go into standby. I have it turned off here, so I don't
know for sure.

You might look at what is running (using CPU and doing IOs) after the 25
minutes is up .. however it'll just be svchost.exe (one of them)
probably.

No the indexing service was OFF, but thank you anyway.

Well, keep looking. My best guess is still that there is something
waking up after 25 minutes of 'idleness' that then makes the machine no
longer idle (or maybe XP just can't count past 25 minutes? 8>.)
