Hi,

I have Acer Predator Helios 300 (Model Name: PH315-52, Part Number: NH.Q53SI.018) purchased in India. I am facing a strange issue where when I turn ON the laptop, the keyboard backlight turns ON fine until the desktop appears. Now, if I do not press any key on the keyboard until it automatically expires after 30 sec, it turns OFF, and then if I hit any key, the backlight does not turn ON. I have to press "Fn + F10" to turn it for the first time on startup and then it functions normally afterwords. 

I tried this both with the adapter plugged in and when not. I also tried updating the BIOS version to "BIOS_Acer_1.11_A_A" and all other drivers up to date but the issue still persists. Even if I disable the "30-sec timeout" in the predator sense app, the issue still persists.

Is there something wrong with any service in the system which tracks the keyboard activity which is not starting on system startup? I see that the predator sense service starts up fine on system startup.

Thanks in Advance!
