This is my old ThinkPad w540 that I used for editing on Avid Media Composer. It was lightly used before I upgraded to a newer ThinkPad. Comes with all original packaging and documentation, also including a Lenovo Bluetooth Laser Mouse.

Just used the included Windows 8.1 discs to upgrade the OS and wipe all my personal data, so you'll have a clean Windows installation (see pics 4 & 5).

Battery still works, but obviously not as strong as it used to be. When I unplug the AC cord, Windows esitmates about 4 hours of battery life.
