If you believe that Bilal Khalid is Satoshi, he says he mined with a laptop.
actual data of the extranonce sequence shows that he mined more blocks of incremental sequence in less time than other users. thus his cpu was faster then average. thus not a laptop
There are many laptops that have much faster CPUs than the average office computer most people are using that do programming on an unknown new internet currency. I myself also started mining on the laptop that Im writing this post on currently.
