Hi friends, I just want to know whether there are any new bios is coming out to support graphics cards HD5450. I have tried several cards which support there in this Desktop but however I have not find.

I have seen that Most of the Lenovo Desktop is not working properly with the ATI GPU which is from 5xxx series. So for that reason if you wish to make include of GPU in your Device then try to install the ATI graphics card.
