The Lenovo ThinkPad W520 is Lenovo's upgrade to the W510 mobile workstation notebook. This 15.6-inch notebook is powered by up to an Intel Core i7-2920XM processor and equipped with up to a discrete NVIDIA Quadro 2000M GPU, switchable to Intel HD integrated graphics. Like last year’s model, the full HD (FHD) displays on the 1920 x 1080 resolution models have a 95% color gamut and a huey PRO color calibration system application.

From the looks of it, the outer build of the W520 is about the same as the previous generation workstation model, the W510. Lenovo stuck with the same ultra sturdy hinges, still evenly built width-wise due to a build fix to the older models. The hinge and display cover are so well-built that it takes a good amount of force to even tilt the screen back or forward (which is reassuring of course). The palm rest and keyboard are both extremely tough as well—showing no flex when typing regularly and only a minimal amount of flex when trying to press down extremely hard.
Pros
- Fabulous 15.6in. screen with colour calibrator
- High-capacity hard drive
- Fast quad-core processor
- Good battery life
Cons
- Cramped USB 3.0 ports
- Bulky and heavy
- No integrated mobile broadband
To my inspection, ThinkPad W520 is an extremely well specified notebook, aimed at specialists running resource-hungry graphics applications which will satisfy your various HD needs. The processor is a 2.20GHz Intel Core i7-2720QM quad-core processor, supported by 4GB of RAM. Graphics are handled by a discrete Nvidia Quadro 2000M GPU with 2GB of DDR3 video memory; this drops to a Quadro 1000M in cheaper models. The sample I reviewed had a 500GB, 7200rpm hard drive — slightly larger than the 320GB unit advertised at Lenovo's web site for this model. The extra capacity will no doubt be welcome to graphics and media professionals. All models run Windows 7 Professional 64-bit.
Gigabit Ethernet, Wi-Fi (802.11a/b/g/n) and Bluetooth 3.0 provide the wired and wireless connectivity. It's a shame there's no mobile broadband support as standard, but this is available as an upgrade option.
There's an optical drive on the right side, along with an SD-compatible media card reader, a 34mm ExpressCard slot, an audio jack and an Ethernet (RJ-45) port. The left side has a smartcard slot, a hardware switch for wireless connectivity, a mini-FireWire (IEEE 1394) port, a combined eSATA/USB 2.0 connector, two USB 3.0 ports, a VGA port and a DisplayPort connector.
The two USB 3.0 connectors are stacked one above the other and adjacent to the eSATA/USB 2.0 combo port, and we found some of our peripherals — a 3G dongle for example — were large enough to obscure the both the other free connectors when in use. Fortunately, there's a further (always-on) USB 2.0 port on the back edge. The RJ-15 modem port is also on the back of the chassis, along with the power input.
Performance & battery life
The Windows Experience Index (WEI) for the ThinkPad W520 was 4.7 (out of 7.9). This corresponds to the lowest subsystem score, which, rather surprisingly, was for Graphics (desktop performance for Windows Aero). The remaining component scores are all very high, with Processor (calculations per second) getting an impressive 7.1. The other graphics subsystem, Gaming Graphics (3D business and gaming graphics performance) scored 6.7 while Primary hard disk (Disk data transfer rate) and RAM (Memory operations per second) both scored 5.9.
Apart from a rather low 2D graphics score, the WEI results describe a fast computer able to tackle a range of demanding workloads.
The ThinkPad W520 comes with a 9-cell battery that protrudes slighly from the back of the chassis. Lenovo claims that our review configuration should run for up 8.9 hours with this battery.
We tested the battery by asking the ThinkPad W520 to play a DVD video continuously. Lenovo provides its usual comprehensive power management application, and we chose the Video Playback option for our test. This power plan doesn't do a great deal to minimise fan usage, and we found its noise disrupted the quieter moments of our chosen video. If your presentations are silent you'll certainly notice the fan kicking in at regular and frequent intervals.
Video played for a total of 4 hours and 6 minutes, which is longer than we are used to seeing from a notebook. Video colours were superb, vibrant, sharp and bright. Sound quality was also very good. Multimedia performance is generally a notch or two above what we'd expect from a standard business notebook — as you'd expect from this top-end configuration.
