Mining Ethereum these days is becoming more and more complex. Eth 2.0 is causing even more confusion to make matters worse. However, questions about mining ethereum from your laptop have come up quite often, so I do my best to answer.
In short, the answer is no; however, for some gaming laptops with a 6GB GPU or higher, you can technically mine Ethereum with them, so if your laptop is not a gaming laptop equipped with a GPU, sorry, the answers a hard NO.
At some point, I'm sure when Eth was first released, this was possible, but these days, the DAG file and mining difficulty make it impossible to do with a CPU. Why you might ask, and in short, my answer to this is that's the way these blockchains are designed to evolve.
However, I want to back and state that even with having a laptop with a 6GB or better GPU, you should st6ill proceed to mine Eth with caution. The reason is that laptops are well equipped to deal with the constant heat that mining emits due to the machine running heavy math calculations 24/7.
You can add ons items such as extra fans or install software that allows you to adjust the CPU fan speeds. Whatever you do, make sure the laptop is running in a room that is cool with lots of circulating fresh air.
If you really want to mine Ethreum, you should really look into building a GPU mining rig with several GPUs instead of trying to run one GPU through a laptop. I'm not saying you can't mine some form of a coin with a laptop and come out on top, but for Eth, you need alot of decent hardware to have a sizeable yield these days.
I hope my answer helps someone out...
