I would HIGHLY recommend buying it online. Look on the bottom of your computer, get the make and model number and type that with "power cord adapter" into google. You have to get the right power cord for your comp or you risk frying your motherboard. You may find it in Yongsan, but if they tell you they don't have it, they probably don't. A new cord will probably set you back $40 - $80 as most cords cannot be shared across different makes. Good luck in your search!
