Okay, so I am relatively new in the field of laptop maintenance and repair, but the other week I managed to swap out HDD's in my Sager without any assistance or issues. The differences between Laptops and Desktops just seems to be hardware placement and accessibility.
My question is where can I buy GPUs, CPUs, and Mobos for Laptops to have infinite customizability for my laptop? I don't want to have to buy a new laptop every few years if I can just buy new parts for cheaper and upgrade my existing laptop.
I think your sager may have mxm graphics card which can be changed, can you confirm that? If you looked into laptop upgrade you find cpu are easy to find and graphics upgrade are slightly more difficult but the major challenge for laptop is the mobo because they not compatible between models.
