Fine but could you recommend good system configuration for mining Monero. I mean desktop or laptop. Assume that i have good internet and electricity for Free Then can i able to make profit by just investing for good configuration computer or laptop

Nope, It would be a waste of time use your laptop to do this, instead of that better read, learn, participate giving opinions or things like that, it's the best thing you can do with with your laptop.
