A friend gave this to me to sell on ebay. The only info they had about the specifics was that it was a mid 2009 model. The screen is 15 inches and the case is in so so condition. No guanrentees when it comes to anything specifically working. I have plugged it in and it boots but there is no harddrive.  This should be considered as not working and for parts only. It comes with the magsafe power supply (as shown in the pictures)
