Legion Y720 Keyboard backlight hotkey not working

Hi, 

I looked through all topic about this, but I don't know what to do.

Nothing worked for me what I understood to do.

I didn't go to Lenovo support to see if they can fix it.

First, all hotkeys with fn+f1 etc are working.

The only thing that doesn't work is Fn+space. 

In order to turn on the backlight, I have to go to Nerve center and turn it on. 

Did I do something to remove this feature that enables me to use this specific hotkey?

As you can see in the picture, this feature is off. How do I enable this hotkey?

If I have to go to BIOS, I'm gonna need an explanation on how to do that. 

Thank you so much for your help Smiley Happy

Hi AngieCRO!

 

Welcome to the Community,

 

Download the Lenovo Vantage, and use it to install all the latest drivers and BIOS.

 

https://support.lenovo.com/us/en/solutions/ht505081

 

Check if the feature works afterwards.

 

Regards,

Re: Legion Y720 Keyboard backlight hotkey not working

Hi Hector, 

Vantage is already pre-installed with a laptop, and I frequently check if all drivers are updated as well as check the system for any errors.

Everything is fine, but as I said, don't know why hotkey won't work.

It worked fine but now it won't work.

Is it maybe because of the update from windows? Around that time hotkey stopped working.

Thank you for your help.

There's also an option in Lenovo Vantage to enable or disable hotkeys, you may check it under Hardware Settings. If the issue persists, reinstall Lenovo Nerve Center and Lenovo Vantage.

Hi Bobby, 

I uninstalled and reinstalled Vantage and Nerve Center. And restarted laptop of course. 

Hotkey still doesn't work.

Also, I checked everything in Vantage to see if there is an option to enable hotkeys and couldn't find it anywhere (I checked 5 times under Hardware Settings first).

What should I try next? 

Thank you for your help.

You mentioned that other hotkey functions are working except for the backlight keyboard. Issue could be caused by the recent changes in Windows due to updates. Try to do a system restore prior to the issue.

Hi Bobby, 

Yes, I did. I tried to do it, but it made it worse.

I had to reinstall some programs such as chrome to make them working again. 

Oh well, I guess I'll just manually switch backlight on/off.

I just hope there aren't other functions affected that I cannot see at this time.

Thank you so much for replying and trying to help guys.
