We've had this issue now for some time now. We ordered beefier 7490s for a few users and their fans are continually on what seems 100%.
I believe the user has updated to the latest BIOS and drivers and we've disabled C-States and still the fan is running at max cap.
Has anyone found a solution to this? If this issue is still persistent, it is a deterrent to continuing to purchase more of the same pcs.
I have the same issue, Fan always runs when it connects to power, it's not bad on battery. Can someone please post the resolution steps to fix this issue.
End task on Bonjour service in Task Manager. This has been a problem on all 7490 laptops that have this service running. Other models do not have this issue.
