This is my beloved 2012 17" laptop. When they put in a replacement logic board, they used one from a 2010 model. it effectively became a 2010 model. The screen is the 2012 model screen
It is fully operational, except no optical drive. there is a space for a second internal drive there.
Power supply is not pretty but it works.
