Computer Diagrams - i need to find computer diagrams?

i need to find computer diagrams?

I just started in a computer repair class and their are a few things i want to know. I tried to find diagrams of the motherboard and such but couldnt find anything extremely detailed. i want to know what those little battery looking things are inside all electronic thins, and the little silver lines on the chips. like all the detailde hardware stuff. there is other stuff i want to learn but this is the only thing i cant seem to find online. maybe im just searching in the wrong way. if you have any idea what im talking about, please try to help by maybe finding me a link or something. thank you!

Those "battery looking things" could be capacitors, diodes, resisters or batteries. If a motherboard is broken then it is better to replace the motherboard rather than replacing components on it. Those silver lines are the equivalent of wires. The could be transferring data of sourcing/sync'ing power. Try searching for Printed Circuit Boards (PCB) for more information on how the circuit boards are created. See the following wiki pages for more info: http://en.wikipedia.org/wiki/Printed_circuit_board http://en.wikipedia.org/wiki/Motherboard http://en.wikipedia.org/wiki/Central_processing_unit
