Mobile workstation for professionals

The Lenovo ThinkPad W540 is a 15.6-inch mobile workstation built around a quad-core Intel Core i7-4800MQ processor running at 2.7 GHz. It ships with 16 GB of DDR3 memory and a 2.5-inch 512 GB solid-state drive. An NVIDIA Quadro K1100M GPU with 3 GB of DDR6 video memory works alongside Intel HD Graphics 4600. Windows 10 Professional 64-bit is pre-installed on the SSD.

Thermals and power in daily use

The processor carries a 47-watt TDP and is cooled inside the compact chassis supplied with a genuine 180-watt AC adapter. The anti-glare Full HD panel at 1920 x 1080 resolution reduces eye strain under office lighting. Fan behaviour and acoustic levels will vary with workload intensity on the Quadro K1100M and CPU combination.

Build integration and expansion

A DVD-RW optical drive and a full-size backlit keyboard with numeric keypad are integrated into the frame. Webcam, Bluetooth and Wi-Fi support remote collaboration without extra peripherals. The 2.5-inch drive bay holds the included 512 GB SSD; memory slots accept DDR3 modules up to a 32 GB maximum. Buyers who want more storage bays or a second discrete graphics card cannot add them internally.

Questions about this item

How do I install the 2.5" 512 GB Solid State Drive into the W540?

Slide the 2.5" 512 GB Solid State Drive into the drive bay and secure it with the caddy screws; the step often missed is fastening the caddy so the connector stays fully seated.

What maintenance or replacement will the 16 GB DDR3 memory need later?

The 16 GB DDR3 memory is upgradeable to a maximum of 32 GB DDR3; no scheduled replacement is required unless a fault occurs.

What limit shows up first under sustained use with the Intel Core i7-4800QM at 47 Watt TDP?

The 47 Watt TDP of the Intel Core i7-4800QM means thermal throttling is the first limit reached during prolonged heavy workloads.
