Hello...

-  2 week old Thinkpad X390   (ordered P/N 20SC0009US )     w Intel i5-10210U 1.6Ghz CPU / 8G RAM /256G SSD,
   
    Order receipt says 'backlit keyboard'.   Keyboard space bar has backlight symbol toward its left;  according to
    some Lenovo Thinkpad web pages, this means my laptop was indeed supposed to be equipped with KB backlight. 

-  Win10 Pro with various updates applied.  All BIOS, etc. updates applied as well.

-  Unclear if backlight worked before updates applied.  Does not work now - Fn+Spacebar shows one of 3 symbols on screen (off, medium, high light)
    Have rebooted etc.   

-  Does not appear that KB backlight is a configurable option from BIOS at boot time.


Is there any patch or way i can further investigate this?   Otherwise very happy with laptop though the advertised
"17 hour" battery life is way over optimistic even with low activity (edit/web browse) and low screen backlight,
and windows set up for longer battery life.

hi，bwiese

When you press Fn+Space, does it show following icon? If you press Fn+ F1 -F12 key，the keys work?  Can you adjust volume up or volume down by press Fn keys? Only Fn+space does not work? Or all Fn key not work?

I have the same/similar problem on a new Legion 5 17IMH05H.  

* All drivers up to date.  

* All other fn keys work and show their overlay icons.

The backlight fn+space will turn OFF the backlight, but not turn it on.   No overlay icon appears in either case.  

 The Lenovo Vantage toolbar software can turn the backlight ON and OFF.

hi, ObiQuiet
