More detail:
Microsoft has chosen to replace the power cords on Xbox consoles manufactured before October 23, 2003.
We are providing replacement power cords because component failure in a small number of consoles - fewer than 1 in 10,000 - has caused burning inside the console or melting of the power cord where it connects to the console.
Microsoft has designed the replacement power cords to protect you and your Xbox from these component failures and a potential fire hazard.
Check the manufacture date on the bottom of your console. No action is necessary if your console was manufactured on or after October 23, 2003.
