Screen brightness keeps reverting to 0%

Hello,

Every time I boot my laptop, or wake it from sleep/hibernate, the screen brightness drops to 0%. It will display the previously saved brightness for approximately 1-2 seconds, before suddenly going to the minimum brightness. This is very frustrating, especially when I'm using the laptop at night as the screen goes so dark I can't see my keyboard to increase the brightness again (the backlit keyboard is always switched off when the laptop wakes/boots, I have to manually switch it on every time. I don't know if this is normal either).

There is no adaptive/auto light adjustment in windows settings - I don't believe this laptop has that feature. The screen will revert to zero regardless of the lighting in my environment. I installed all provided drivers when I received the laptop.

I have tried to search for an answer on Google but this doesn't appear to be a common problem as I cannot find anyone with a similar issue. I thought maybe it's an issue with PC Specialist/ TongFang builds perhaps. I've already RMA'd this laptop once for severe CPU and GPU performance issues (motherboard was replaced). I really hope I don't have a dud.

Cheers!
Chris

Does the brightness drop to 0% before Windows loads or after? If it's before, then it would seem to indicate a hardware fault somewhere...if it does it after Windows has loaded then it points to a driver/setting issue.

I would try rebooting into safe mode and seeing what happens...if it doesn't happen then it means there's something in Windows causing it. If it still does it, would likely point to hardware
