I have a Dell Latitude E5420, which I have upgraded to 16GB RAM and thrown in an SSD. It currently houses an i3-2310M, and I'm wanting to upgrade that as well. Before I hear the countless comments, let me dismiss the big two. Yes I know the upgrade isn't worth it. My daily driver is an ASUS GX501, I just like upgrading my old systems. And secondly, yes this is a socketed CPU not soldered, I know there'll be plenty of comments saying "Laptop CPUs tend to be soldered" so I'm saying it now, this is a socketed CPU that can be upgraded. Now onto the main topic, if I keep at the same socket and TDP, the best CPU I could theoretically upgrade to would be an i7-3632QM. However I don't know if that will work in my laptop since DELL is nonsensical with their laptop BIOS. So I was wondering if any of you fine folk have upgraded this laptop or have any experience with this and can help me determine the best I can put in this old timer. And one last time, yes this is pointless, I just like upgrading even if it's a 1% upgrade, and yes this is a socketed not soldered CPU platform.
