Do you own a Surface Pro, Surface Pro 2, or Surface Pro 3? If so, and if you made your purchase before March, 2015, you should know that Microsoft has just issued a recall for the AC power cords for those devices.
According to a spokesman for the company, the recall was issued because over an extended period of time, an extremely small proportion of customers owning these devices reported problems with excessive heat, and a potential fire hazard, caused by the power cords being wound or bound too tightly for an extended period of time.
