upgrading components in a laptop/notebook is extremely difficult at best, excepting the ones that are designed to be removed easily. Depending on the computer, this can include RAM, HDD/SSD, Wireless Card, Disk Drive, but I have never seen the processor or video card in this situation. It's probably a better option to buy a new laptop, assuming it is possible at all to upgrade at all.
you cant do it
it can be done but it will cost you a lot of cash first take your laptop to its company and ask them for upgrading the cpu they will tell you that you will have to change the entire motherboard if they accept it you will pay them maybe more than half of the laptop price
