Can you give me some guidance if you know?
Imho the proper guidance should be: stop using laptops for mining.
Laptops don't handle well running 24/7, laptops may not have proper heat dissipation, all in all, laptops are not fit for mining. And you have a good chance to damage the laptop way before the ROI (PS. Did you calculate the electricity cost vs the income?)
All in all, I think that you're doing it wrong and you may have to ask for guidance in the altcoin mining section (I do hope that at least you don't try to mine Bitcoin with your laptop).
