This is the motherboard from my retired Samsung NP530U4C laptop computer. The number stamped on the PCB is Lotus-14R_INT, Rev 1.1. It includes an Intel Centrino processor, as you can see in the pics. It was working fine when the computer was retired for unrelated reasons. I would expect it still to work fine, but cannot test and thus cannot guarantee it.
