Display brightness issue

Hi everyone, I’m having an issue on my Rog Strix G16 laptop where after turning off and turning back on the device the brightness will be set always at the ‘silent’ mode, even if I last had it on performance mode. The interesting thing though is the brightness slider will show it set at whatever mode I had the laptop last on.

For example, I had the laptop on turbo mode which was max brightness. I turn off the laptop and turn it back on and the display brightness is very dim, (silent mode), but if I look at the brightness slider it’s at 100% max as the turbo mode would normally be. I change the slider and the brightness is then fine, or I change plans and that works too.

Any ideas? It’s practically brand new and I have already reset it once.

Interesting thing I’ve found after troubleshooting is that this does NOT happen after disabling fast startup or when I restart the laptop. E.g. laptop was in turbo mode, restart laptop and laptop is in turbo mode with brightness slider at full and brightness display is at max brightness.

Anyone else having this problem? Shall I either disabled fast startup or just continue to change plans using buttons on keyboard until the brightness works properly? Cheers!

I would disable fast start up
Doesn't seem to make much difference
If any on my pc
Though I rarely use laptop
So can't specifically say about those
But you can test it anyway
Just had similar with a new monitor
A firmware update fixed it
But with a laptop it might just be a windows update
Will fix it
Not certain if firmware affects the screen in laptops
To be quite honest

Thank you, I have disabled fast start up and it works fine now and only adds 0.3 seconds to the boot time.

Ahh interesting you had a similar issue with your monitor. I think you're right that it's Windows, others are having similar problems as me! Cheers for your help.
