I have tested the following: USB ports, camera, microphone, trackpad, all keys, speakers.

The battery has over 1100 cycles and will need to be changed. Sold as-is.

This only has 4GB of ram. Make sure that the software you want to use can run on this computer. This computer is 9 years old. Do not buy this if you want a new computer. This is not a new computer.

Minor signs of wear on body and screen. See photos for details.
