How is it that certain electronic goods are designed to fail? Planned Obsolescence is just that, planned. So what goes into designing failing systems of computer? Hypothesis: Perhaps there are defects in the n and p-type doped semiconductors. The lattice entropy increases over time producing defects in the semiconducting material. The joule heating of any electronic device supplies the energy to increase entropy. So if one could design an electronic system to dissipate and increasing amount heat over time then more defects in the semiconductors will occur. The question is do computers dissipate more heat over time? When does a computer typically fail?
