Lenovo Legion 5 15ARH05 - Backlit keyboard not turning on? Fn + Spacebar NOT WORKING

2020-07-12, 17:20 PM

So, recently I've noticed the Fn+spacebar shortcut doesn't toggle my backlit keyboard to turn off or on. The weird thing is, the backlight turns on when I start up my laptop but the moment I turn it off and try to turn it back on later with Fn+spacebar, it doesn't work at all! 

 

I've heard this might be a BIOS problem but I checked everything on Lenovo Vantage a bunch of times and the program insists that everything is up to date... what should I do?? 

Solved! See the solution

Hi there Jae1C

 

Welcome to the Community Forums.

 

Try heading over to the Support Page for your device and download and install the newest Chipset / Serial I.O and Management Engine Interface drivers for your device. Also look for any firmware driver updates for your device if any. These kind of updates don't normally get updated through the Vantage app as far as I know.

Just plot in the serial number for your device and hit enter, might have to hit it twice. Then head to Drivers & Software then Chipset

Please make sure you have your AC adapter connected when applying these updates.

 

Hope this helps.

 

Regards

I just received a Legion 5-17IMH05H and have also updated the drivers and BIOS and am having the same issue with no back light on the keyboard.
