i Use a HP Envy with a Navida GeForce and Intel core i7, how do i use this to mine ETH?
if you want to mine eth with that laptop, you really need a external gpu
you can use any thunderbolt 3 ports on your laptop to connect extarnal gpu's easy
OR
without any thunderbolt 3 ports. What you need is , remove the wifi mini card from your laptop, and plug a mPcie to Pcie adapter to the mPcie port .
you going to need a externap computer PSU , the adapter card and some work
if you want to do more than 1 extarnal vga card , you can try to use any pcie splitter there is no guarantee those splitters going to work and support all 3-4 slots , but you have a good chance to run 2 cards with those splitter / mPcie to Pcie adapter combination . You have to make sure your external psu can handle the load
