Seemed pretty straightforward. Googled the computer model number and the words 'power adapter' and the store popped up on the right hand side of the search results. Generally I skip paid placements like this, but they had the best price and most coherent product description (as opposed to Amazon). Orderings was simple. I thought the shipping was on the high side, though.
