I am new here so I hope I behave well. I want a motherboard for my HP 350 G1 laptop. The existing one is SNOWI10-6050A2608301-MB-AO5 (core I7). In searching, I find more that seem just the same but have the number SNOWI10-6050A2608301-MB-AO4 (not AO5). Is the AO4 likely to work in place of the AO5? Thanks for any advice. I have never replaced a motherboard before, so this is a new adventure for me.
