This bundle includes a Lenovo ThinkPad T420 (type 4177) running Linux Mint OS, a ThinkPad Mini Dock Series 3 (type 4337), two spare batteries that attach to the bottom of the laptop to extend the use time, a DVD Multi drive, a ThinbkPad SATA Hard Drive Bay Adapter III (interchangeable with the DVD drive) with hard drive, and two power adapters.

ThinkPad Specs:

Intel Core i5-2520M @ 2.5GHz

8GB RAM

Crucial MX500 1TB SSD

DVD/CD drive

All the batteries work and hold a charge but they are old so they won't last as long as new batteries would. The Windows 7 Home Premium product key is located under the primary battery bay.
