    BGA sockets are soldered IIRC, so upgrading it isn't really possible.

    Even if you had the technically know-how to remove it & re-solder something else that's socket compatible, you'll likely find a lack of BIOS support for most other chips. The N551JX models did have offerings with an i7-4720HQ, so it *could* work..... but it's not an easy upgrade, with no guarantees of functionality.

  3. Changing a BGA cpu requires experience, and expensive equipment and very few are willing to do it. It's not going to be cheap and failure rates are high. SO even of you manage to find somebody willing you may end up paying them to end up with a brick.

    To upgrade your option is to buy a N551JX motherboard that already has the i7 soldered to it.

    You really can't. You need to basically chop the cpu from the motherboard and hope you didn't break a single small connection (which is basically impossible not to have happen) in crude terms..

    They are soldered CPU's, so you would have to find one that someone already desoldered and is selling, I cant find any, they will likely be few and far between. Your only option will likely be to harvest one out of another laptop and unless you have done this before and been successful you will likely not be able to desolder and resolder a CPU, it's no easy task.
