A Playstation Portable blows up in a students pocket burning a hole through his pants. The student suffered minor burns to his leg. What could have caused such an over heating in this device allowing it to explode. This is yet undetermined, Police are still investigating. While Sony says it is an isolated occurrence, this wouldn’t be the first time a Sony product with malfunction battery exploded. Hmmm reminds me of a certain laptop incident read here and here too.
