# ThinkPad W series

The ThinkPad W series laptops from Lenovo were described by the manufacturer as being "mobile workstations", 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'. The W series laptops were launched in 2008, at the same time as Intel Centrino 2, marking an overhaul of Lenovo's product lineup. The first two W series laptops introduced were the W500 and the W700.

### W540

Announced in 2013 and released in the US and Europe early 2014, the W540 featured a brand-new, slimmer design based on the new generations T540p. Slimmer than the prior W530, the new design received mixed reactions from traditional ThinkPad users. Critique was mainly aimed towards lower build quality and missing user interface indicators, together with a new style of touchpad where the traditional ThinkPad trackpoint functionality had been radically changed, and the controversial island style keyboard introduced in 2012 on other products, which many enthusiasts claimed abandoned the core tactile principles established by IBM over previous decades.
The new W series however featured newer hardware such as the option for a 3K 2880 x 1620 IPS display. Other new features included:
* 4th generation Core processors
* Upgraded Quadro GPUs to K1100M and K2100M
* Full size keyboard with numeric keypad (though offset from center of screen, causing criticism from those who rarely use the keypad)
* New touchpad/trackpoint integration (though TrackPoint "thumb" buttons were removed causing criticism due to lost tactile feedback)
* Changed UltraBay design (the easy eject locking buttons were replaced by a hidden locking screw rendering "hot swap" functionality moot and earlier UltraBay modules incompatible)
* New rectangular connector for charger (rendering earlier accessories and docking stations obsolete)
* Thinner profile
* Lighter weight

### W541

The W541 is a ThinkPad W540 featuring the new-style keyboard but with a re-introduction of the classic ThinkPad touchpad design. The prior ThinkPad touchpad design featured in the W540 and other 4th-gen ThinkPads was abandoned.

### W550s

Rather than being a successor of any previous W-series model, the W550s is a thinner Ultrabook variant of the W series; Likewise a latest P5xs series ThinkPad, the W550s was based in a T-series chassis. While a capable Ultrabook, when compared to the W541 and its predecessors, it offers less capability with only dual-core hyper-threaded Intel Broadwell processors vs. the true quad-core processors of other models and has only two RAM slots.

## Discontinuation and successor

The ThinkPad W series was discontinued and replaced by ThinkPad P series, beginning with the P50s, P50 and P70 in 2016. The P70 re-introduced the 17-inch screen to the ThinkPad workstation line.
