This listing is for a Lot Of 3 Apple MacBook Pro 13" laptops that all power on but have various issues. I don't know the exact years of manufacture, but two say A1278, and the other has no visible model number. One is in good cosmetic condition but took a few times once plugged in to get to the home screen without shutting off, then while it functioned, it was very slow. The second one started up and went to home screen fairly quickly, but the flat control pad was slow to respond, and it also operated slowly and has a cracked screen. The third one would start up, but shut off before it would get through loading process so home screen was never achieved. This unit also has a broken screen. These units are being sold AS-IS and for PARTS/REPAIR and do not include any accessories, cables or power cords. See photos for more details, and I will attempt to answer any questions you may have...Thanks!
