Responder a:Microsoft surface pro 4 mother board schematic helpHello, Unfortunately I haven' t got the schematic. Also for surface 1 they were not available. But if anybody have got them, I would also take them. But I' ve also got another question. Is your surface fitted with 8 or 16gb of ram? I ask because I want to upgrade my Ram from 4 to 16gb and I also ordered the necessary chips already. These are K4EBE304EB-EGCF ones from Samsung. But now I'm not sure whether it is necessary to equip also the marked areas in the pictures with components. https://picload.org/view/dgrpgrdr/pictur... https://picload.org/view/dgrpgrda/pictur... Now my question for you is the following. If you have removed your mainboard, could you please take a look at the marked free areas in the picture and check if there are any components are mounted. And if there are should be any maybe you could take a picture or tell me what' s there because there are absolutely no pictures in the inernet. Thank you very much for your help.
