According to your description, I suggest you refer to the following information:
The cpu, graphics card and motherboard of notebook products are highly integrated and customized products. Replacing any component alone may lead to hardware compatibility problems, and the upgrade flexibility of these components will be very low, not only CPU and graphics card, but also wireless network card. To improve the performance of the notebook, we suggest upgrading from the aspects of memory and hard disk capacity. Upgrading these two parts has high security and compatibility.
Because these two parts are our reserved extensible components, and the associated interfaces also meet the unified standards.
If it is confirmed that the original notebook spare parts can't meet the existing work requirements and you want to upgrade the spare parts, you can try to contact the Gold Medal Service Center for consultation.
You can check the nearest HP Gold Service Center through the following website:
