This website made me feel confident that I ordered the correct charger. I glanced at the typical sites that came up like amazon and Walmart but I just was not sure about what I was ordering. Two choices came up for my charger on this site so I had to look at the old one to know which one. Of course it was the more expensive one which made me really think the other sites might have been less expensive but this is for sue the right part. It was not that expensive in any case. I just generally let someone else handle my computer but I figured I could probably buy a charger then had to stop and look at the electrical specs! At least I can read the specs. I am on the other side of the country or I��d go in and pick it up.
