IdeaPad C340 (14", Intel) can't turn off keyboard backlight

I just bought Lenovo IdeaPad C340-14IML Yoga and installed Windows 10 Home. I turned on keyboard backlight with pressing Fn+Spacebar , but after a while I found that I can't turned it off any more. I try with Fn+Spacebar and from Lenovo Vantage Toolbar, but with no result. Also I tried with turning on safe mode and rebooting but with no result again. I guess the FN button is not the problem because it works fine with other combinations. I ran a hardware test from Lenovo Vantage and it passed with no errors.
Does anyone have an idea how to solve  this problem.
Thanks in advanced!

Hi @Irensh,

 

Welcome to the Community Forums!

 

Does the space bar work when you type in Notepad, Word Document, or browser?

 

Please perform a power drain

 

If the issue persists, backup your important data and perform System Restore from a previous restore point or reset your PC

 

Let us know how it goes.

 

Regards,
Maru

Every thing works fine except this combination... I returned the laptop for repairing and the problem was the motherboard

Hi,

I also bought the same laptop with the latest 10th gen but I am not able to turn on the backlit keyboard. Any recommendations or suggestions for fixing that issue would be much appreciated.

 

Thanks,

Rambo
