Still ongoing.
The issue actually reoccurred again today.
I'm glad that it's not just me, or my hardware, but it would be really nice to have something to trace to try to resolve the issue.
I have not noticed it on my home desktop, but my home desktop is rarely ever left on but not in use.
Out of curiosity, what brand are the laptops? Maybe it's a Dell issue (my work machine is a Dell desktop, with dell peripherals)
