If you own a Surface Pro, you might want to be careful using it for the next little while. Microsoft tells Channelnomics that it's planning a voluntary recall for the power cords on every Surface Pro tablet released before the Pro 4 and sold before a certain period (March 2015 in the US, July 15th in Europe). The tech giant warns that the AC power cable could trigger a fire if it's wound too tightly or otherwise damaged. Only a "very small" number of people have reported problems, Microsoft says, but the company isn't taking any chances.
