I have a 3 year old DELL desktop computer that 4 times a year travels back and forth across the state with me to and from college. Nearly every time I make sure to label which power cords go to which machines, but this last time I forgot. Now I have two power cords, one to my monitor and one to my CPU and I do not know which cord goes to which. One is a Longwell E55349 10A 125V LS-13 LP-31 The other is Foxconn E301899 10A 125V FM-008 The computer itself is a DELL XPS 410 produced in 2006, and the monitor is a standard 19" that was included with the computer package. Any help would be appreciated. Thanks so much!
