I am working with two Windows 7 desktop computers, both of which have a unique problem I have not seen before. (To reiterate, these are not laptop computers; they have no battery and hence no battery settings that can be set.) One of the computers has a brand new monitor, and the other has a monitor that I have no reason to believe is malfunctioning.
Please be advised that this dimming is coming while the keyboard and mouse are active. I do believe -- please correct if I'm wrong -- that active keyboard and mouse will bring a dimmed or display shutdown computer out of those states with an active keyboard and/or mouse.
I can be working right along using the keyboard and mouse. All of a sudden, the display dims for no apparent reason. The display will not brighten back up with vigorous mouse movement.
I have looked at articles like this, but I thought displays turned back on with keyboard/mouse activity, let alone never dim when there was mouse/keyboard activity already present.
My question is what setting or settings might be causing this? To the best of my knowledge no one has installed or set a screen saver that might be causing this.
