Great condition, no signs of use at all on the exterior, but the battery needs to be serviced (it still works but will only hold a charge for 30 minutes to an hour). The computer works great plugged into power, and the battery does still work for short periods of time, but you will probably want to get the battery serviced at an Apple store, and potentially get a new battery (unless you plan to only use the laptop at a desk where you are plugged into power, in which case it works great as is). 

I'm including the charger and also a dongle with USB 2 ports and SD and micro-SD card slots. Let me know if you have any questions!
