gogole the laptop and words service parts. see if there are part numbers for cpu chips. a lot of laptops have cpu chips fixed into the system board and cant be changed. if there are cpu it be up to the vendor on what cpu that laptop can take.
Processors on laptops are usually integrated into the motherboard, therefore cannot be swapped out and replaced. Unless you replaced the entire motherboard. But, upgrading laptops is a very difficult task, and I would only advise you do it if you are an expert at it or are confidently following a trustworthy online guide.
One way to check if it is upgrade able is to see if the specs say that it is soldered or socketed. If it is soldered, then it means you can't upgrade it. If it is socketed then you can. Most laptops don't have upgrade able cpus as the laptop is small. Only high end laptops and some hps have this option.
