I have an old pavillion laptop that I just took apart and want to replace the parts to improve it. I am new to this so I am very ignorant to a lot of the cans and cannots of laptop replacements. However, I would like to know if you can replace the wifi card and processor with any wifi card and processor with anyone that fits or does the wifi card have to be the same version and does the processor have to be the same AMD Turion 64 X2? I don't mind having the AMD I just know that this is old and want a better one. I included pictures too I hope it helps.
