HP Pavilion dm4-2191us, 8GB RAM, 250GB SSD, Windows 10 EVGA GTX 560 Ti (1GB VRAM?) Blue Star 650W PSU EXP GDC Beast V8.3 (from GearBest) Hey guys, just got my GDC Beast V8 in yesterday and put my eGPU setup all together. I know my PSU works and I know my GPU works (tested in another machine). My HP laptop has whitelist, so I tried booting with my wifi card, putting computer to sleep, hotplugging mPCIe adapter in, and turning the computer back on - but windows doesn't detect the GPU. I've also bought DIY eGPU Setup and hotplugged whilst in that, and even then the GPU doesn't register. I tried doing the same on another (Dell Inspiron 1420) laptop, with the same results. I can't figure out what is wrong, short of the HDMI to mPCIe cable being bad. But it doesn't seem bad since the GPU/PSU turn on/off when I turn my laptop on/off. Further, I've tried taping over pin 22, as well as hotwiring the PSU to be always on before hotplugging the adapter into my mPCIe port. Still no luck. Are there more settings I need to be changing in DIY eGPU Setup, such as link speed or width? I really thought hot plugging was the defacto tell on whether or not your setup works or not. Thanks for your help!
