A series of Microsoft tablets have power cord errors.

Starting today (January 22), Microsoft will activate a recall program for defective power cords of Surface Pro, Surface Pro 2 and Surface Pro 3 models sold before July 2015.

The main reason for this recall is that the power cord of the above Surface Pro models has an overheating error that can be dangerous to users.

"We are launching this free recall program after receiving complaints from some Surface Pro users that their AC power cords have issues, specifically twisted or bent cords that cause overheating," said a Microsoft spokesperson.

The recall may not apply to power cords that are in perfect working condition—that is, not deformed like bent or twisted—and it also doesn't apply to the Surface Pro 4, which was released late last year.

Additionally, the program does not apply to non-Surface Pro tablets. That means anyone who purchased a Surface Pro, Surface Pro 2, and Surface Pro 3 before March 2015 in the US will get a free power cord replacement.

For users in other countries, Microsoft's faulty power cord replacement program will be rolled out shortly after the US market.
