I’ve been trying to help a friend install a GTX 1050 egpu on his HP 8470p EliteBook (which is a laptop on the supported list). He has 8 gigabytes of ram and an integrated HD 5000 graphics chip. He has tried both the Mini PCI-E version and the express card versions of the graphics card dock, and both have just given him a black screen while the caps lock and other lights that usually flash during post just continue to flash. He went as far as to update his bios and try an AMD card instead, but the computer will not post with any graphics card inserted into the slot at power on. We have both read over the manuals here multiple times and looked for YouTube videos, but nothing seems to help. Does anyone have any idea why the computer won’t boot?
