Are computer power cords interchangeable?
On One Hand: Desktop Power Cords Are InterchangeableWith rare exception, power cords for modern desktop computers are safe for use on any other desktop. In general, if the cord fits into the power supply unit, it will safely power the computer. Many monitors use the same power cables, and those can also be safely swapped.On the Other: Laptop Power Cords Are NotIn general, power cords for different models of laptops are not interchangeable, and should not swapped. DC power cords for laptops come in different voltage and current ratings, and often have different connectors. Even if the connector fits, the power cord should not be used unless it is meant for that laptop.Bottom LineDesktop power cords are interchangeable but laptop power cords are not. If you lose the power cord for a desktop computer or monitor, feel free to use another one you have laying around. But do not try to use a laptop power cord that is meant for a different laptop.Source:Tech Guy: Are Computer Power Cords Unive
