Apple MacBook 13,1" Laptop -  (May, 2007).

The original polycarbonate MacBook 3,1 (13-inch, Late 2007) was Apple’s first notebook to use new features, such as the glossy display, the sunken keyboard design and the non-mechanical magnetic latch. The MacBook 3,1 (polycarbonate model) followed the same line. With this late-2007 revision, the MacBook keyboard received several changes to closely mirror the one which shipped with the iMac.

The battery does not hold a charge. It works when it's on the charger. Charger included.
