I have a Dell precision M4700 laptop (CAD workstation), with a AMD M7700 professional graphics card that can no longer be detected.
This forces me across to the integrated Intel HD 4000 graphics. Wouldn't be a huge issue as I now rarely do graphics intensive stuff on my personal laptop, but it seems that only the M7700 runs the display-port's. I have a nice 1440p 27" monitor, so using the laptops screen while I am at my desk sucks in comparison.
Anybody know how to diagnose a failed graphics board so I can be comfortable to order another off ebay?
Have managed to get the graphics card back live twice. First time (for 10mins or so) by updating the bios (subsequent update didn't get it back, bios is now current). Second time was then I physically removed the graphics card, then reseated (takes about 30mins of dismantling to get to it).
I assume I could just drop in a new card like this if the graphics board is faulty?
