I think mining BItcoin (BTC) can not use laptop because the capacity of RAM, Memory and Procecor in laptop is not able to offset server. mostly for Bitcoin miners using computer assembled PCs. the specifications of RAM, Memory and others have been enlarged. Not to mention to mine require air conditioner, Fan and expensive electricity cost. because the computer must be On 24 Hours. that's what I know to mining.
But i have heared that MENORO is the only currency which you can mine on laptops. what do you say?
It's Monero, not Menoro. There are much more coins which you can mine with CPU. Monero it's just most popular and maybe most profitable. But it's not worth using laptop, and wont earn significant amount of coins. I suggest to forget this idea.
But if you are interested, you can check this thread to see coins which can be mined with CPU:
