I got rid of this idea because the mobile gpu is faulty but I came across a modification that let you use desktop gpu on a laptop, it's available at a store in China I'm not just sure if it's going to be worth it or not. Thanks for the contributions guys 👍.
Mining on laptops has long since died. Some miners still use laptops, but these are old purchases.
An external GPU costs more than a regular PC GPU. If you really want to mine now, then buy a small mining farm in an open case.
