The top is from one laptop in the bottom is from another laptop. they look similar but are not compatible. Use the top and the bottom as separate parts or try to get the bottom working with your own hard drive and operating system. We can provide a VGA monitor and the adapter to use it. The battery is dead but I think we had it working with the external monitor. you have to provide your own power supply. The bottom is a A1286 from 2010.
