Replaced hard drive of Samsung 7 Series

Hello friends, i have just changed the hard drive of my laptop from 750 gb 5400 rpm hd to momentus 500gb / sd, so when i change it then i lost all functions of mouse pad, so tried to download drivers from Samsung website then also no helpful for me. Even tried to run easy settings, then giving me error that computer's model or operating system is not been supported by the easy software manager and telling me to download and install from Samsung mobile website. So does anyone has any idea about it, how to solve the problem? I am having the NP700Z5B-W01UB i7 Samsung 6gb RAM. Thank you.

Did you try to re-install the window, even you can try to download the ELAN PS/2 Port Smart-Pad touch pad drivers from the internet and do upgrade of the system, which might be helpful for you.

I have the proper solution for it, go to Samsung website and select the different model in series 7 of notebook, now you download the driver of touch pad driver and install it. It will be worked fine, even you can go to below link and get the driver for you.
