yes I am going on a 3rd return right now for a 7510Gx series. If I have one more problem with it, I will file for no lemon. The issue is screen flicker.
yah this is a 7510gx with a upgraded processor (7510gx=3700+ 7525gx=4000+). Both have the same video card, same video ram, same system ram, same HD, list goes on. New name a little high proc, wham...got yourself a new model.
