Hi Friends,
We do face SOC failure in newer motherboards very frequently and the exact SOC may not be lying around. SOC's are difficult to source as reliability is a big question mark besides being expensive as well. So, an alternative can be like getting a SOC from scrap board(You have to be sure that soc is ok). I myself started https://www.badcaps.net/forum/showth...&highlight=SOC this thread but it was inconclusive for various reasons. Many of you must be wondering, which SOC will work on a particular motherboard and do waste a lot of time replacing with an incompatible soc.
So here is simple guide to make a firm and foolproof decision in finding out which soc will run on a particular mb.
WARNING: SOC replacement is not an easy job and requires very good bga skills. The soc may bend due to improper profile,bad reballing. Same profile wont work on evry motherboard as some mb may tolerate heat well whereas some others may bend. So be careful.
SOLUTION: You need only one tool "MC Extractor"(MIcrocode Extractor) to get cpu id from your bios dump.So do the following based on my experience with HP15-LA-A992P Rev 1.0
01. Download MC Extractor tool. Its attached here for your convenience.
02. Open the exe file by double clicking on it.
03.Drag and drop your bios dump on the opened MC Extractor tool.
04.Press Enter.
05. Microcode will be displayed on the tool.
06.Open Intel microcode update guidance pdf file from here

07. Look for CPU-id you need and make sure you select "mobile" in Vertical Segment"
08.Now you know the list of processors which will support on that particular mb.
My LA-A992P mb had SR1EK as original SOC whereas i succesfully replaced it with SR170 as both have same cpu-id(40651) though there are differences between these two processor like Core Stepping. I've succesfully replaced SOC on many motherboards with these simple steps and hope it will help others as well.
I'll be happy to answer any queries.
