Lenovo Thinkpad W541 Laptop - Core i7-4810MQ @2.80GHz, Nvidia Quadro K1100M, 8GB DDR3L, 256GB SSD

Used Lenovo Thinkpad W541 Workstation Laptop in very good condition. Bought in 2017 for $1700 and incrementally upgraded and maintained over the years. I have upgraded the display, memory, boot drive, and Wifi chip. I have replaced the keyboard. It works like new except for the battery noted below. Reason for selling: Bought a new laptop to replace it. ** ISSUES ** 1. Detachable battery is dead. MUST be run while plugged into power unless you get a new battery. The battery is external and detachable, so it is easily replaced.
