It's mainly used for college and watching Netflix. The processor is slow and I can live with it, but it just would be better if it was possible for me to change out the processor to be better.
Is it possible to change my processor to a better one on my Lenovo Ideapad 120S laptop?
Yes "Possible",
NO! Not practical.
a CPU chip is matched to the motherboard to get maximum efficiency.
Use of a "better" chip will be a wasted expense, as the motherboard will bottle neck the system.
Then there's the problem of "Solid State", laptops are all Fixed to the motherboard (except sometimes RAM & Hard Drive) so they will not come loose during travel.
Its HIGHLY unlikely, i have only seen a few (less than 5 models) that can upgrade to a new processor.
generally they are soldered to the board and non swappable.
If you had a desktop computer and decided to switch the processor you could by just buying a new one and taking the old one out or by buying a new motherboard and processor combo. For laptops, you can't really buy a new processor since the processor is usually soldered to the board and it would be a big mess if you took the processor off and put a new one on. It is not practical to do it.
No. Laptops are not made to upgrade their processors under normal conditions. If you're a hacker then you might have the resources to do it but I'm assuming you aren't, like the 99% rest of us…
