Issue

More recent versions of Windows 10 do not respect the "min power savings" setting used by Imaging Toolkit 10 to keep machines awake.


This means that during phase 3 Application Installation, machines may go to sleep if application installation takes a long time.


Ideally one would simply configure new power settings using a phase3-before script, however the build process alters the power settings after the phase scripts have run, therefore negating any settings applied.

NOTE:This issue has been fixed in Imaging Toolkit 11.0 and this workaround should be removed from any project(s) after upgrading

Solution

Upgrade to Imaging Toolkit 11.0.


If upgrading is not possible create a script which is launched asynchronously by the phase3-before script and polls waiting for a point after the power settings have been configured to set the updated values.

Procedures

1.Add powerscheme.vbs to project Custom Files
 
2.Update phase3-before.vbs to launch powerscheme.vbs
 
3.Test

  1. Add powerscheme.vbs to project Custom Files

    • Download the attached powerscheme.vbs file

    • Open the affected project in Build Console and add the powerscheme.vbs file to the Custom Files view

  2. Update phase3-before.vbs to launch powerscheme.vbs

    • Right-click and Edit the phase3-before.vbs in the Custom Files view

    • Add the following lines:

      Utils.AppendLog "Launching powerscheme.vbs script"
Utils.Run "wscript c:\ztoolkit\powerscheme.vbs", 0, false
    • Save the file 
    • Validate the project and then use the Deployment Wizard to recreate the Build Process (ztoolkit) image 
    • Copy the updated ztoolkit image to your imaging server/share 

  3. Test

    • Build a machine using the new ztoolkit image 
    • If the scripts have been correctly implemented the machine will not go to sleep during phase 3
