The ThinkPad W series laptops from Lenovo were described by the manufacturer as being "mobile workstations",^[1] and suit that description by being physically on the larger side of the laptop spectrum, with screens ranging from 15.6" to 17.3" in size. Most W series laptops offered high-end quad-core Intel Core processors with an integrated GPU as well as an Nvidia Quadro discrete GPU, utilizing Nvidia Optimus to switch between the two GPUs as required. Notable exceptions are the W500, which has ATI Mobility FireGL integrated workstation-class graphics, and the W550s, which is an Ultrabook-specification laptop with only a dual-core processor. The W series laptops offered independent software vendor (ISV) certifications from various vendors such as Adobe Systems and Autodesk for computer-aided design (CAD) and 3D modeling software.

The W-series laptops were introduced by Lenovo as workstation-class laptops with their own letter designation, a descendant of prior ThinkPad T series models suffixed with 'p'.^[2] The W series laptops were launched in 2008, at the same time as Intel Centrino 2, marking an overhaul of Lenovo's product lineup.^[2] The first two W series laptops introduced were the W500 and the W700.
