Supplying power cleanly and without bursting into flames is the basic function of a power supply. That's true for all electronics, of course, and Microsoft's Surface Pro line is no different. That’s why Microsoft is recalling the AC power cords for the Surface Pro, Surface Pro 2, and Surface Pro 3 sold prior to July 2015, according to ZDNet.
Here's the scoop:
"As a result of damage caused by AC power cords being wound too tightly, twisted or pinched over an extended period of time, a very small proportion of Surface Pro customers have reported issues with their AC power cord. We will be releasing details of how customers can obtain a free replacement cable shortly," a Microsoft spokesperson confirmed to me today via e-mail.
Apparently the Surface Pro 4 already has the new and improved version of the power cord, and so if that's the version you're sporting, you're already covered. The voluntary recall is actually upcoming, according to a Channelnomics Europe report, with more information coming on January 22. Note that in the U.S., covered devices sold prior to March 2015 will be included.
So, if you've found your Surface Pro, Surface Pro 2, or Surface Pro 3 power cord to get a little warm, help is on the way. Hang tight, and Microsoft should be contacting you soon to organize the transfer.
