I was the last one who posted on that link above and I actually ordered one of the suggested power supplies from there and it didn't work (the barrel was too thick). Then I talked to Asus Support and they gave me the model of what their system returns when they entered my laptop's serial number and after I received the one they recommended it didn't have the right tip either, so I am going to send it back (see point #1 below).
I called the Asus store again today and they have no other supported listing for this specific model, I guess this model of laptop is unique since it was perhaps only sold at Best Buy or so?
In any case my options are boiling down to this:
1) Try to get a converter that goes from the tip of the 230W adapter I bought to the laptop
2) Order the G-model 180W adapter and see if it works
3) Return the laptop and get something else, since I have not been able to get in touch with any other owners of this exact same model and get the exact adapter model to look for one online.
