So I recently upgraded the mobo in my E6420 from the intel hd to the NVS board which left me with a spare board.
Then I had an idea: I have a parts lenovo with an i3-3120m, and the i3 fit in the socket.
So I put the CPU in the Dell board, put a battery on it, turned it on, and it stayed on, it even warmed up!
The only problem is that I was getting no display output, But I think that has more to do w/ the i3 having HD 4000 rather than HD 3000.
Any insights on this would be helpful.
