The strong processors also use to generate a lot of heat. Laptops are usually designed to allow a bit of cool down now and then - by stopping them now and then and/or by not leaving them hours after hours on 100% processor use. With GPU it's even worse.

Since mining is usually high CPU/GPU use and 24/7 run, you may end up by breaking the laptop early if you are lucky or burn down the house if you're not.


So if you want that badly to mine, I'd advice you do that only while you use the laptop for something else (like surfing the net or this forum) and use mining software that doesn't use the whole processing power (like the Stak miner for Monero). But you'll see that such mining will get you pennies over long periods of time and may not worth it.
