[QUOTE="cwa107, post: 684040, member: 24098"] I would just add that although there is a lot that can go wrong, typically it doesn't. In fact, the logic board (or motherboard, or systemboard, depending on your terminology) is comprised of 100% solid-state circuitry. Unlike mechanical devices like hard disks, fans and optical drives, they should be far less prone to failure. In my experience, most solid-state hardware failures are usually induced by something environmental (high humidity, liquid, intense heat, etc). It's rare to have a logic board fail due to manufacturer defect (like a cold solder joint), especially since the entire world has moved over to surface mounted components. Back in the day when computers actually had socket-mounted ICs, motherboard failures were a lot more common. In fact, we used to use techniques like "The Atari Twist", to correct a motherboard failure (i.e. reseat all of the chips by twisting the entire chassis of a machine until you heard it "crunch"). These days, it's relatively unheard of to see a motherboard die due to a manufacturer defect. [/QUOTE]
