Keyboard Backlight Not Working After Hibernation When Using GHelper (Windows Dynamic Lighting Off)

[Juah56]

Hello,

I have an Asus TUF Gaming A16 FA608 (2024) laptop and I'm having an issue with the keyboard backlight when using GHelper and Windows Dynamic Lighting is turned off.

Here's the problem:

When I disable Windows Dynamic Lighting and control the keyboard backlight using GHelper, everything works fine until the laptop goes into hibernation.

After waking the laptop from hibernation, the keyboard backlight doesn't turn on at all, even though GHelper is running.

To fix it, I have to either restart the laptop or turn Windows Dynamic Lighting on and off again, and then the keyboard backlight starts working based on GHelper settings.

This issue does not happen when the laptop wakes from sleep mode — only from hibernation.

Also, if I control lighting through Armoury Crate and pair it with Windows Dynamic Lighting, the backlight works correctly after hibernation. But I prefer not to use Armoury Crate or Windows Dynamic Lighting because they are limited and a bit clunky.

I really want to control the keyboard lighting only through GHelper, but after the laptop wakes up from hibernation, the keyboard backlight doesn't work at all — the keyboard stays completely dark and unresponsive.

As soon as I turn Windows Dynamic Lighting on and off again, or restart the laptop, the backlight comes back on and I can fully control it through GHelper, switching between all modes without issues.

However, every time the laptop goes into hibernation and I turn it back on, I have to repeat this process again. It becomes a loop where I constantly need to toggle Dynamic Lighting or restart the system just to get the backlight working with GHelper.

Is there any solution or workaround for this?
Could GHelper be updated to reinitialize the keyboard backlight properly after hibernation, even with Windows Dynamic Lighting turned off?

Thank you

@Juah56 hello, did you try using latest https://github.com/seerge/g-helper/releases/tag/v0.214 ? I have added a workaround specifically for your model there

Ahaa, I hadn’t noticed that at all — I just tried it now and it works. Thanks a lot, you’re a legend!

Hi, I found out today that the issue is still happening, although less frequently than before. After about 10 wake-ups from hibernation, the keyboard backlight failed to turn on 2 times. Do you know what might be causing this, or how to fix it? :/

[Juah56]

Hi, so today after waking the laptop from hibernation, it happened again. But this time it occurred in a strange way: the laptop was in hibernation, I plugged in the charger, and only then I turned it on. It’s just weird — I don’t understand it.

Check app's log, do you see Dynamic lighting ON / OFF lines AFTER wake up ?

[Juah56]

I don't see any 'Dynamic lighting ON / OFF after wake up' in the log — I already sent the log above.

@Juah56 ok, thanks.

Your laptop seems to wake up (screen turns on, etc.) before Windows has fully resumed G-Helper, which prevents it from acting in time.

Try this build — it should initialize Dynamic Lighting in all power state changes.

Alright, thank you.

Hi. Is there a way to get the keyboard backlight to work on boot and not on sign in? I downloaded the version given and then also tried the latest version and it only works after signing in. I have it set so it should work on boot and awake. Also sometimes it doesnt turn on even after signing in and requires a manual toggle of dynamics light. Asus tuf a16 FA608WI

@SlySylveon hello, the workaround with Dynamic Lighting init is long time live in all releases (as a result of this issue #3990)

Obviously app needs to start first, to do it's thing :) And it starts after you sign in.

You can also simply enable Dyanmic Lighting in windows instead, and then lighting will be always on.
