I am not a computer guy but I am a reliable ebay person. This device was used by my family. It is well used, shows some wear on the case, as pictured but overall is really in pretty good shape. The display looks great. The laptop itself works great, too. Please look at the pix. Hopefully those will answer any of your questions. My reply will mostly be, "umm" but you can still ask.

The charger and device are original apple products.

Thanks,Bob
