Inspiron 15 7570 Keyboard Light Not Working

Hello Elliot,

I've just updated the BIOS utility and encountered the same problem.

I searched for solutions to the problem and found only your post directly related.

Seeing there is no answer I thought I might be able to find a solution myself and I did.

Please follow the steps below:

1. At boot press F2 to go to the BIOS utility;
2. Go to System configuration -> Keyboard Backlight with AC: found it already enabled;
3. Disable it and click Apply;
4. Enable it again and click Apply;
5. Check the keyboard light by pressing Fn+F10 (at this point for me it stayed on, no more fading);
6. Exit the BIOS Utility.

This solved it for me. Hope this works for you too.

Cheers,

Cristian

Hi Cristan,

I know it's been several months since you posted in this topic, but if you check back here would you please post your BIOS version number? I have the same system as you do but I don't have the "Keyboard Backlight with AC" option. If I can get your BIOS number, I will upgrade (or downgrade) my BIOS with that one. I have been looking for a way to keep my keyboard light on for months!

Thanks!

Hello there,

I have got this same problem.

After upgrade BIOS to newest version i lost my keyboard's backlight.

Is it possible to downgrade BIOS to the older version?

Have you tried to reset the bios to defaults? I don't have this system but when I had odd problems after a bios update that solved it.

Hi, MuskyCM,

the BIOS version must have been at 1.14.0 at the time of my post.
I hope this helps.

Best,
Cristian

Check your BIOS settings to see if you can configure backlight illumination there.  And if you haven't already, try Fn+F10 rather than just F10 in case you changed your Function lock so that the F keys act as F keys by default rather than performing the function shown on their icons.
