Power setting keeps resetting monitor off to 20 minutes after restart

Yes, before anyone asks, I have made sure that the power settings in control panel have been set to "never" under advanced settings. :) 



About 4 months ago, windows decided to set my monitor shut off time to 20 minutes. The first time it happened, I figured it was a one-off thing, and set the monitor off setting back to "never".

Fast forward 4 months, and I have to turn the setting to "never" every time I start my computer.

I've even made custom power profiles, and every time I restart, the monitor off setting keeps going back to 20 minutes.

I've looked online for a solution, but all I've gotten is that it's a random bug that hits win7, and currently can't be fixed without reloading. I was hoping that one of you guys had a solution. Thanks in advance!

I'm not sure what age this computer is, but does the CMOS battery need changing?
I'm not sure what type of security you have , but did you try turning the security off while adjusting the power settings?
restart the computer and turn the security back on?
Did you try to create a custom power profile with you own monitor setting?

Reloading the OS is not a lot of trouble,
put the win 7 disk in and select "upgrade"
this reloads the OS without erasing your personal files. And, does not reformat the drive.
after that I would try leaving the automatic updates shut off for a while, and see if it's an automatic update that is corrupting the OS.
I shut my auto updates permanently. I use an all in one professional antivirus, and leave the microsoft updates. I find that this leads to a more stable system, and freedom from surprises that come along with automatic updates.

already tried it

already did, see my OP

Already reloaded/repaired in early Feb, due to a dx11 error.

This is a bug that microsoft knows about, and doesn't know how to fix. I was hoping that one of you guys might have a registry/ 3rd party software based solution. No worries though, I figured it wouldn't be able to be fixed without a full reload; I was just grasping at straws at this point.

Hello. I've had a somewhat similar issue with my power settings changing on their own although it wasn't every time I rebooted. It turned out the issue was being caused by a program called HD Tune (I use HD Tune Pro v5.0). Basically, HD Tune launches but then when I use it to run any kind of a disc check/scan/test it changes the monitor power off setting back to the default 20mins. It doesn't care if it's a windows generically installed power profile or a custom one I've saved. Whatever the present power setting is for the monitor gets changed to the 20min number. Weird! If it helps frame anything for ya I am running Win7Ultimate 64bit. Hope this helps and Good luck solving your issue.

Good job finding this bug with hdd tune m1kegallacher maybe other programs may cause this to happen as well?
I can confirm that Hdd pro 4.6 changes the monitor settings back to 20 mins. I just set my monitor to shut off at 40 mins opened hhd tune did a quick error test stopped it b4 it finished closed hdd tune opened power settings and it was set back to 20 mins i repeated this bug 3 times in a row.. that is odd..

You can set the entire OS back to default, which may eliminate these bugs...
put the win 7 install disk in the drive and select "upgrade." This does not erase your personal files or programs, but replaces the OS files.
Then AVOID any free software downloads...if you load free stuff from the internet, there's no telling what will happen.
Always use a professional security application, not a free one from the internet.
Avoid any "free" players, games, fixers, cleaners, scanners, etc...

Also, my personal preference would be to avoid anything but critical updates. Updates are known to corrupt the systems, but this does not happen on all computers, just some. I leave automatic updates turned off, and as a result have much fewer problems.

I thought for a while my computer was going haywire.. Could not figure out why monitor settings kept changing to 20 minutes. This is computer connected to a DLP HDTV and monitor can not be turned off by the computer. Thanks to your explanation (and Google), problem now resolved. It was indeed HD Tune Pro. Why the heck does it do that?
