I don't know if either of those will work.
Use the best buy part store to do a search for your laptop's model number and it'll give you a list of accessories. Usually the power cord and a few alternatives are there. I wouldn't recommend buying from them, because it'll be hella expensive. Just take the model number of the charger(s) it gives you and do a search on ebay/amazon.
