One thing that has puzzled me with Vista was the fact that the screen saver wouldn’t activate, and so the screen was staying “on” – and noticed a mini screen burn a week or so ago. Just turned it off over night, and was gone – but still a concern.
One quick I’d assumed was that the wireless keyboard and mouse couldn’t be used to “cancel” the screen saver – hence it wasn’t being turned on.
I did a bit of a search – and found this :
When you use a Microsoft wireless pointing device that uses Microsoft IntelliPoint software on a Windows Vista-based computer, you may notice that the screen saver of the computer does not work even though it is configured to run.
Yep – that sounds like the problem !
This mentioned something about PCM and DVDLauncher services running in the background (?), and part of a Dell operation system – nope, not for me. But – also said to :
Install the Optional Hardware Update that is named Microsoft HID Non-User Input Data Filter.
There was a quick & easy Windows Update “optional” component to install – and all OK. Didn’t even need a re-boot – the screen saver now comes on as expected – yay !
Here are the details of the update :
Microsoft – Other Hardware – HID Non-User Input Data Filter
