Thanks mate. I didn't expect that you are still monitoring this post. Good to know that it works on clevo machine. I have tried this adapter on Zbook 15 g2 and Dell Precision M6700 with optimus enabled and UEFI boot mode only. I have tried two GPUs, 750TI and GTX980.
For 750TI, the sleep/hibernate function works if I disable the gpu before putting laptop to sleep/hibernate. Putting the laptop to sleep/hibernate overnight will break the initialization of the gpu with the gpu detected as 3D video controller under other devices.
For GTX980, I got BSOD after waking the laptops from sleep and I also tried disabling the gpu from device manager before putting the laptop to sleep but I got BSOD after re-enabling the gpu. Hibernate seemed to work for a while if I disable the gpu first before proceeding to hibernate but putting laptop to hibernate over night also breaks the initialization of gpu.
I haven't had an occurrence where the laptop will randomly go to sleep when I am using this adapter. I have been using it for gaming and Topaz video AI for video upscaling. Gaming is so far stable but I had a BSOD when using Topaz video AI last night, suggesting driver issues.
The NVIDIA driver versions I have tried are 391.35 and 536.67. Just putting my finding here, in case, anyone finds this useful or happens to have a solution to this problem.
