Lenovo T-420 Laptop. Intel Core i5-2520M CPU, 8GB RAM, 300GB Hard Drive, Win 10 Pro 64 bit operating system, freshly installed. Everything works perfectly, even though caps for two keys are missing. The one on the left the Function key, the other is for a Ctrl button. They don't affect the performance, and can be replaced.

Shipped with USPS Priority Mail.
