Dear Intel Support,
I have a Latitude E5450 laptop and after a driver update, afaik, the device stopped working.
Tried reverting to the previous driver, messing with BIOS settings and doing a clean installation of Windows with no luck.
Seems to be the same issue that's been discussed in these threads:
So I'd like to request the ULP tool to see if it resolves my issue.
I tried the ULP tool but it did not seem to work (the tool says nothing, so I may have botched the use of the tool).
Elsewhere there are six people who solved the issue by removing all power sources (mains, battery) ideally including mobo onboard CMOS button battery.
