There are 4 white boxes on the left side from CPU labeled 1,2,3,4 on the Lenovo Y50 motherboard (please attached photo). My replacement motherboard has box 4 marked with a marker. I am wondering what those number mean. Is it some kind of indication of the motherboard grade and if so, is lower number higher grade or opposite?
