The Inq writes the countless Xbox 360 deaths are caused by poor surge protectors:
According to Law of the Game, technical support are reading from a card saying that the Xbox 360 is highly sensitive to reductions in power, and even the slightest cut in power can cause things like the fans and even the DVD laser to malfunction.
Apparently ninety percent of the failed consoles have been plugged into a surge protector, so Vole thinks they are responsible. Using a similar logic 100 percent of them were also switched on so maybe the power switch is to blame.
Vole is saying that you should let your Xbox run free a surge protector and experience lightning strikes, power surges and brown outs.
