I had a similar issue. Baking work momentarily but I ended up using a Dell X600 from a D810. WAY cheaper, and since all those cards wont play jack anymore, it will just give you better battery. Wasn't a perfect transition though. The saga is here: E1505+6400 and M1710+m90 video card compatibility
Anyway, just do a bit of reading or PM if you decide to take that route.
