Thinkpad X250 window 7 hotkey F4, F7, F8 not working

Hi,

 

recently, hotkeys F4, F7, F8 of some Thinkpad X250 in our company stop working, the OS is windows 7.

 

I have tried to update the driver, still the problem is not solved.

Did you update power managment driver a while back?  That was causing porblems for other people with Fn key and OSD see below.

 

the solution was to roll back the power management driver.
