Probook 6470b
Microsoft Windows 7 (32-bit)

I have a Probook 6470b with Windows 7 Enterprise.  It is connected to a NEC m322x projector via VGA cable.  

 

As a domain administrator, I go to "Choose when to turn off display" and set "Dim the display" and "Turn off the display" to NEVER.  This way the picture does not turn off while the teacher is presenting.

 

I have ONE computer where the settings seem to change themselves - to turn off the display after xx amount of time.  Teachers and students do not have access to that setting.  Is there a way to prevent this from happening?  This is the only computer it is happening on.
