You need to contact the laptop manufacturer so they can provide you a list of fully supported processors for your laptop system.
Keep in mind that the compatibility between the Intel processors and any laptop system is determined by the laptop manufacturer, not by the processor manufacturer.
Adolf is right, but if you encounter a bad will person at the manufacturer, and a slow response, you can verify it your self. Download a program (freeware) like cpu id, where at the mainboard you will have the model used (the notebooks don`t highlight ever the mainboard used) and google it. You will sure find details of what socket and processors can sustain. Good luck. You can also use wikipedia for intel processors.
