Lenovo ThinkPad W541 with a Core i7-4710MQ Quad 2.5GHz processor, 16GB memory, and a 256GB Samsung SSD drive, 2GB NVIDIA K1100M Graphics Card, 1920x1080 Display, with Windows 10 Pro.&nbsp; This is a nice system with some wear, and a blemish on the lid (see pics), and some sticker residue on the bottom.&nbsp; The battery is new, but is an aftermarket ($25.99 off of eBay), not Lenovo.&nbsp; The battery seems to work fine.&nbsp; The laptop runs great.&nbsp; Comes with 170W Lenovo charger.<div>Thanks for looking</div>
