Hello,
Recently I bought an Eurocom X8 and I am having trouble getting the brightness control to work. My laptop has 2 970m GPUs in SLI, and a 120Hz screen LP173WF2 which uses eDP. I couldn't get it to work in Windows 8.1 until I flashed a Prema BIOS and Prema VBIOS on the GPUs, then tried like 7 or 8 different NVIDIA drivers until it worked. However, I recently updated to Windows 10 and the brightness control has stopped working. I would really like to get it working again but in Windows 10 instead of Windows 8.1. To me, it seems clear that it is not a hardware issue since I did get it working at some point. However, the weird thing about this is, the one time I got it working when the screen brightness was set to 0/the lowest, the display turned off completely... I don't think this is normal since I have never seen any other Clevo laptop do this, but perhaps I am wrong and that is normal. Also, hotkey was all messaged up with everything saying null and literally looked like this: http://i.imgur.com/XOwmboa.jpg I emailed Prema and we talked back and forth and couldn't really figure it out. I tried a newer stock BIOS/EC that he said would work with Windows 10 for brightness, but that didn't help, so then I went back to the latest Prema BIOS/EC (. I'm thinking it's something to do with the NVIDIA drivers, perhaps a configuration issue or something, maybe there is a setting I can change somewhere, or I need a custom NVIDIA driver somehow or something? Enabling/disabling SLI doesn't help,
I am willing to pay money to whoever gets this fixed for me. I will make it worth your while.
Thanks.

I looked through the emails that Prema sent me before. I tried something he suggested before and it didn't work before (or perhaps it did, because eventually brightness started working on 8.1).
He suggested this to me:
"Your BIOS and EC are fine now, must be the fact that Windows was setup with broken BIOS.
Try to add it manually:
1) Open regedit and go to the "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class" key.
2) Find the sub-key corresponding to the NVIDIA graphics adapter. I did this by going to Find in the Edit menu and searching for "nvidia".
3) Add a new DWORD called "EnableBrightnessControl" and set the value to 1.
4) Reboot and the brightness keys should work again."
I did it just now, and it worked again. To me, it seems like this fix should work for any non-iGPU display/laptop that doesn't have any working brightness control.
Well, I'm good for my word, so I'm going to donate to Prema again (this is like the 4th time I have donated to him, he really deserves every penny of it).
Mods, you can close this topic now.Last edited: Aug 1, 2015Bullrun likes this. -
