Can i change my processor on laptop?
Yes you can change a processor, but I will recommend you don't do it and go for a new laptop. It is rarely of help to change because other problems will crop up.
Most upper end laptops (not netbooks) come with the processor mounted in a socket. You can replace it with any other from the same socket series, however, be aware that laptops are built to only handle the power and heat requirements of the original build. If the processor was an option in the original build you should not experience any trouble.
Well, you can change but you won't be getting any better performance. The data bus speed and other stuffs comes on the way and that needs a lot of replacing. And even it might effect the cooling design of the system as well. Yes, if you have some tech stuffs.you can but find the right CPU. But my suggestion would be to buy new one.
Yes, you can processor in laptop.
Not to my knowledge. I think that laptop motherboards are designed to only support a certain make and model CPU. You could replace the CPU you have now with one that is the same, but you can't upgrade it to something more powerful is what I'm trying to say.
