How to use Group Policy Preferences to manage Windows Power Plans

One of the new feature of Group Policy Preferences in Windows 7 and Windows Server 2008 R2 is support for configuring power plans using preferences for Windows Vista and later (see Image 1). You used to be able to control power management in Vista using native policies however the advanced targeting of preferences now enables lot of new scenarios with power savings. AWSOME!

One of the really neat things that you can do with Group Policy Preferences (GPP’s) and Targeting is change the power scheme of a computer based on the time of the day and the day of the week. This allows you to apply more aggressive power plans to your workstations after hours but then then back off during the day when people are working. Even though that Windows Vista (and Windows 7) support adaptive display time out which backs off the screen saver timeout when a user is still sitting at a computer but not actively using it they still have to wake up the computer by before the timeout started to back off. Applying the less aggressive power plan during working hours means that the user is less likely to have to keep waking up their computer in the first place as you have configured longer time out values.

Now if this sounds familiar you’d be right as I did demo some of this during my TechEd Australia Group Policies session that I did with Lilia Gutnik and it is similar to the TechNet Edge video by Michael Kleef and Mark Gray. But in this article I am going to diving a lot deeper than my demo or in the TechNet Edge video.

So before we talk about how to do this first lets go over what we are trying to achieve. We are assuming you manage a fleet of workstations that are only used during standard business hours and afterhours you want the computers to go to use as little as power as possible. You want to apply different power plans to the computers not only based on the day of the week but also the time of the day to make sure you get maximum possible power savings (see Image 2).

So to do this we setup two separate power plans, with one that is applied by default all the time and the other one that will take precedence and apply during business hours.

How to setup the Default Power Plan Policy

Step 1. Create a Power Plan under the User Configuration option of a GPO that has has aggressive power savings configured without any targeting other than being applied to all the users you want to control the power plans. I will leave the exact details of the power plan up to you but I will recommend that if you are going to set the “Sleep” timeout for Windows Vista (or greater) then make sure you also enable the “Allow hybrid sleep” option (even on your desktops) (see Image 3.) as this will protect your computers from data loss if you lose power to your office environment afterhours.

Step 2. Rename the item to be called something like “Default Power Plan” (see Image 4) and also make sure that it is always set to order number one.

WARNING – If you do this make sure you either immediately disable the item (tool bar > red circle “disable this item”) or setup the Business Hours Power Plan straight away so that you don’t start shutting down all your computer during the middle of the day.

How to setup the Business Hours Power Plan Policy

Step 3. Create another Power Plan setting item called “Business Hours Power Plan” (see Image 5.) making sure it is lower order than the default power plan. Again I will leave the exact settings up to you but this one should be less aggressive than your default power plan.

Step 4. Now go into the properties of the “Business Hours Power Plan”

Step 5. Click on the Common Tab and tick “Item-Level Targeting”

Step 6. Click on the targeting button

First of all we are going to create a collection that will target the Business House Power Plan to only the weekdays of the week.

Step 7.  In the targeting Editor click on “Add Collection” (see Image 6.)

Step 8. Click on the “New Item” and then click on “Date Match” (see Image 7 & 8.)

Step 9. Now you will need to drag the “AND the day of the week is Sunday” onto the “the collection is true” and change the day to “Monday” (see Image 9.)

Step 10. Now make sure that “the day of the week is Monday” is highlighted and click CTRL-C once and CTRL-V four times to copy and paste the date match rule once for each weekday (see Image 10).

Step 11. Now click on each of the “AND the day of the week is Monday” and press F6 to change each date match rule from and “AND” to a “OR” and then change the days to Tuesday , Wednesday, Thursday and Friday (see Image 11).

Now we will add a Time Range option that will refine when we target the Business House Power Plan to just working hours of the weekdays.

Step 12. Click on the “this collection is true” and then click on “New Item” and then click on “Time Range” (see Image 12).

Step 13. Now configured the time range to when during the day you want to Business Hours Power Plan to apply (see Image 13).

Note – Make sure you allow for the policy refresh interval (default 90 minutes with a 20% random offset) when configuring the start and end time. This means you might want to start applying the policy 2 hours before the start of business (e.g. 6:30am) to make sure all the computers are configured with the Business Hours Power Plan before people login in the morning (e.g. 8:30am).

Now you have configured a Group Policy Preference to apply less aggressive power plans to your computer during business hours while still having more aggressive power plans applied after hours.

Other Option – More user Control

In the example above we just modified the “Balanced” power plan setting when we wanted to make changes to the power settings. If you did not want to give your users some more control and not force specific power plans you could just select the “High performance“ plan and tick “Set as the active power plan” for the Business Hours Power Plan (see Image 14) and the “Power Saver” plan as active in the Default Power plan (see Image 15).

This way your users can still configure each of the power plans to their own preference but you will still make sure that the “Power Saver” plan will be applied to your computers after hours. However as you are only setting which plan is active then your users could get around the power plan as by configure both plans to never time out thus negating the benefit of any of the plan’s.

Other Options – Less aggressive Default Power Plan

You may also want to set the default power policy to be less aggressive by default and then apply the aggressive power as the second item in the list using a little more complicated targeting (see Image 16). The advantage of this method is you can easily turn off the aggressive power savings plan when you want to do afterhours by just disabling the “Afterhours Power Plan”.

    I have been testing the GPP and found that if I use a "computer does not belong to a security group", the GPP does not work. The rest of negative statements worked OK. For example especifying "The computer does not belong to OU or domain or site , etc… These work. Does somebody has an idea about this issue??? (Marco Sanchez)

  2. Alan Says:

    Check the security filtering on the Group Policy Object… also run a Group Policy Report against the computer you are testing from the Group Policy Managmenet console to check which groups are being used for the processing of the policy.

    i can´t see the gpp option power plan for (Windows Vista or later) i only can see power option and power scheme but only for windows xp.

    Hello,

    We have about 500 xp desktop and laptop in 2003 AD environment that I would like to manage the power scheme.

    I installed GPMC on Windows 2008 and connect it to the AD and created a special OU with GP with the User Configuration power scheme. I added one of the machine as the target and installed XP Group preference Client-side extention. I ran gpupdate on the client machine that I tested but nothing is happened. The power scheme didn’t change at all. Also I enabled the log tracking and there is no log created.

    Did I make a mistake or this GPP doesn’t work in my AD 2003 and Windows XP client environment?

    Your input is much appreciated.

    regards,

    Morning, I know the post is old, but I have got rid of some old management software that didin’t warrent the price on renewal – Server 2008 is more then able to perform most of the functions out of the box. The above info is excellent though I am slightly confused.
    From what you are saying the policy is applied to the user which seems counter intuitive – that said having tried to apply it to the computer doesn’t work.
    so If I have 2 OUs, one for the computers and one for users – where is the policy applied? Is it applied to the ‘user’ part of the computer OU, or directly to the ‘user’ OU? If to the user OU are the settings persistent even when the user logs off. In other words during evenings and weekends will the power save plan remain in force?

    • Alan Burchill Says:

      This is a strange one. But the computer policy only applies until a user logs on…. Then it will always apply the power plan of the last logged on user.

      • Sean Says:

        I have tried applying it at: computer OU in both the computer and user settings – didn’t apply. I have applied it to the user OU in the user settings and it still didn’t apply. do I need to use loopback processing and apply it at the user section of the computer OU.
        Many thanks
