Hi all, I hope someone can help me out... I've seen a few videos online of people installing the AMD FirePro M5100 into the HP Elitebook range - 8540w, 8540p, 8560w etc. I've got an 8560w, and have just bought an M5100 to upgrade it, but when I start the laptop, the screen is black. Sometimes, you see the backlight come on, and sometimes you don't. Can anyone advise how to get this going, please? Thanks muchly!
