Thinkpad T470s Star and Scissors Keys Stopped Working

I have my keyboard set in Lenovo Vantage to load a website when I press the F12/Star key.  It was working for the entire time I've had my computer, but stopped about 2 weeks ago.  Also, today I tried to use the Fn+PrtSc/Scissors key to take a screenshot, and that is not working anymore either.  It could have been one of the recent Lenovo updates, but I'm not sure.  Does anybody know how to turn these keys back on or to figure out what is causing them to not work anymore?  Thanks!

Did you update power management driver recently?  That is casuing FN key and OSD problems.  Solution is to roll back the power management driver.

The Power Management driver had been updated last month.  I went into Control Panel, Device Manager, System, Lenovo PM, and deleted that.  After restart, the keys work again!  Thanks!

Delete or ROLL back the driver?  You still need the driver for power management.  By the way thanks for coming back to mark "solved"

Rolling it back and restarting didn't fix the problem, so I deleted it.  After restart, it's automatically back in the device manager and the computer is working, so I'm happy.

Ah ok.   Thats good then.  Glad it worked out.  I noticed Lenovo removed the bad driver from Vantage and the website.
