This motherboard from an Acer Laptop was given to me by someone I work with who knows I've been getting interested in computers. You can see the two RAM slots but I can't for the life of me figure out where the address and memory buses connecting these to the CPU are. Any help is appreciated.

Somewhere on layers 2 through n-1 on a n-layer PCB. – Ignacio Vazquez-Abrams – 2018-04-09T02:10:19.560
Sorry I'm still new at computers. So you're saying they're buried under the motherboard and therefore not visible? – Jaull – 2018-04-09T02:13:56.773
They're routed on one of the inside layers of the motherboard. It is not strange for a x86 motherboard to have 6, 8, or even 10 layers. – Ignacio Vazquez-Abrams – 2018-04-09T02:14:57.033
ok thanks for responding. So they're just not on the surface then, right? – Jaull – 2018-04-09T02:16:16.930
Not for very long, usually. The outer layers are usually ground, for RF/EMI purposes. – Ignacio Vazquez-Abrams – 2018-04-09T02:17:01.807
