    The V3-331, as far as I can determine, does not employ a socket mounted CPU. The CPU is a BGA (Ball Grid Array) device which is surface mounted. Intel use the term 'socket' (in the case of the i5-4200U, the 'socket' is fcbga1168) but in reality it is not a socket at all and likely simply indicates a connection map.

     

    While it is not impossible to replace these at home (it would require a rework station, hot air or oven etc) it is generally considered not to be a user exchangeable part. Below is a link to a Russian YouTube video which details the procedure (for a BGA graphics chip):

    While it is possible to do this at home without the 'proper' equipment, it does require considerable precision and preparation. Ideally, you would want to obtain a stencil for applying the solder paste. The likelihood of shorts, non connections or simply destroying the motherboard due to incorrect heat profiling is not inconsiderable!

    Hello,

     

    Could you give me the first ten characters of the laptop serial number (S/N)? Only the first ten.

    Thanks for your info.  I realized that the CPU was solded in the motherboard after I made my first post and it is difficult for me to upgrade CPU by my own hand.
