– so the AC adapter weighs about a third of the computer itself. A smaller “travel” adapter is available as an option, but why not supply it as standard to promote mobility for the overall system package?
One of the most popular features of ThinkPads has been the positive tactile feel of the keyboard, and the W520 continues this sentiment. Keyboard feel is great, but layout of some keys (such as Delete) is a challenge at first and may annoy some users because of unconventional placement. Also, there is no dedicated numeric keypad, not a big deal for me personally, but some users may take exception. The real estate area normally devoted to the numeric keypad is occupied by speakers on either side of the main keyboard. Is it a good tradeoff? That’s a personal opinion, but I did not miss the numeric keypad nor appreciate
the quality of the speakers.
The keyboard is spill resistant and the unit actually has a drainage system that funnels liquids into reservoirs on the underside and drainage holes on the bottom. I’m a big coffee drinker when using a computer, so for me this is a welcome “preventative measure.”
Being a mobile system, it will inevitably receive some hard knocks. This is idea behind the ThinkPad’s Active Protection System that uses an accelerometer to park the hard disk if the ThinkPad is dropped. When the shock sensor detects that its environment is stable again, it turns the hard disk back on.
Behind the scenes, the ThinkPad W520 is protected by a magnesium roll cage in the bottom shell that provides internal reinforcement to reduce system board flex, as well as dispersing internal heat. Speaking of cooling . . .
Cooling is not an area that most of think too much about, but for the ThinkPad, I didn’t really have to think about it at all. It has two exhaust vents on the side and back, as well as additional air flow vents on the bottom. The uniquely designed cooling fan blades minimize turbulence and are quiet. The fans also run at five speeds (compared with three found in many competitors), so the transition between speeds is more gradual (and noticeable).
I liked that the W520’s USB ports were 3.0 – providing 50% more power for connected devices and (at least theoretically) 10x data transfer. I don’t know about 10x, but data transfer was noticeably faster than 2.0.
Battery life was also pretty impressive. The W520 was supplied with a 9-cell battery that extended almost an inch beyond the back of the computer, but I was regularly able to get over seven hours of productive work (CAD, word processing, spreadsheets, etc.) with WiFi turned on.
The W520, like all ThinkPads, has a well-integrated Power Manager for controlling energy use. For example, with a simple slider bar you can move from “high performance” to “long battery life” (to conserve and maximize battery life) or to “high energy savings” (when plugged in to AC power). As you adjust the slide bar, the system dynamically adjusts display brightness and other parameters according to the new settings.
The 15.6-inch 1920 x 1800 matte display provides 90-degree left and right viewing angles. It’s also extremely bright with brilliant color – very nice for displaying animations and renderings.
The ThinkPad W520 has a number of software vendors who have certified the W520, including Autodesk (AutoCAD and Inventor), Dassault (SolidWorks and CATIA), PTC (Pro/ENGINEER and CoCreate), and Siemens (Solid Edge and NX). Although we did not test all of these certifications, the fact that the W520 is certified for these applications strongly indicates that it lives up to its claim as a mobile workstation. I did, however, run SolidWorks 2011 and Inventor 2011 on the ThinkPad W520, and was quite impressed by the levels of performance with larger assemblies, simulations, animations, and rendering. Overall, performance was
Portability and Power
The ThinkPad W520 starts at $1299 and the system we received nicely configured was $2539. This is roughly in line with competing systems and should not be a detriment for those of you shopping for a mobile workstation that is truly mobile, as well as having capabilities for MCAD applications. Battery life also makes it suitable for field work untethered to AC for extended periods of time.
Is the Lenovo ThinkPad W520 perfect? Not exactly, but as a mobile workstation for a wide range of MCAD users, it’s very capable, truly portable, and an overall good value.

The Week’s Top 5
At MCADCafé we track many things, including the stories that have attracted the most interest from our subscribers. Below are the five news items that were the most viewed during last week.
Granta Design announced details of the Eco Materials Adviser Full Version, which will build upon the sustainable design tool currently available within Autodesk Inventor 2012 software, at no extra cost. Autodesk Inventor Eco Materials Adviser helps designers to estimate a product’s environmental impact and to make more sustainable design decisions. The Full Version, available for purchase from Granta later this year, will enable users to analyze larger assemblies, to study materials options in more depth, and to account for a wider range of contributions to environmental impact. Using the Eco Materials Adviser,
currently a designer can quickly generate an eco impact analysis for a product part or assembly within Autodesk Inventor. An easy-to-read dashboard display shows key indicators such as energy usage, restricted substances, CO2 footprint, water usage, and materials cost. Any Autodesk Inventor user can interactively explore the sustainability impact of changes in materials choice or the design of their digital prototype. The Full Version will enable more in-depth analyses.
i GET IT, the online self-paced training solution for engineers from Tata Technologies, announced a new packaged offering with 3Dconnexion that focuses on delivering significant improvement in productivity for engineers. Through July 31, engineers can purchase an i GET IT Platinum training bundle subscription – a comprehensive education package – with the 3Dconnexion SpacePilot PRO 3D mouse included, for $495, a combination that normally retails for $794. This special training bundle offer expires July 31. For details:
Dassault Systèmes announced that DraftSight has surpassed one million downloads. Over the past year since the launch of the no-cost 2D CAD product, users have been utilizing its functionality for all types of CAD. Every month, the DraftSight website features the latest user stories and encourages new users to submit projects showing the inventive ways in which they’re using the product. In the past year, DraftSight has launched the general availability of the product for Windows, a first and second beta for Mac and recently, a beta version of DraftSight for Linux. Along with these products, DraftSight unveiled
its own DraftSight community, an online community that provides learning resources and encourages user questions, collaboration, and support. This community is one of the first social networks designed by engineers for engineers, designers, and architects.
Majenta PLM announced that it has been awarded a contract by super-yacht design company, John Shuttleworth Yacht Designs, to supply and implement Siemens NX design software. The software will be used throughout the entire yacht design process, including conceptual design, hull fairing and detailing, structural design, interior design and superstructure and deck gear design and detailing. With their new solution, the final 3D models created in NX of a complete yacht, including the hull form originally created in MacSurfPro (a popular hull-shape design tool among the yacht design community) form an integral part of the design
package that John Shuttleworth Yacht Designs now issues to a ship-yard. Along with a comprehensive set of 2D detail drawings, these models enable the yard to take measurements and sections required for the construction process and to generate CNC tool paths for cutting patterns for mould tools. The NX model is also used to generate photo-realistic visualizations of the yacht’s exterior and interior for client presentation and design review purposes during the design process.
Dassault Systèmes announced a joint project with Astrium and EADS Innovation Works to develop solutions based on Dassault Systèmes’ Version 6 platform that will enable to improve Astrium’s and EADS’ internal engineering methods, through the use of an innovative and revolutionary concept: the functional digital mockup (FDMU). The FDMU, unlike a digital mockup, which is associated more to the 3D geometry of a vehicle, will play an essential role during the exploration design phase. Based on Dassault Systèmes’ RFLP (Requirements, Functional, Logical, and Physical) concept, it will
add a whole new dimension to multi-disciplinary collaboration at various stages of development, using CATIA, ENOVIA and SIMULIA. The goal of this project is to prove that increased teamwork between the different disciplines will ensure that vehicle solutions which may have otherwise been overlooked will be brought to the forefront and discussed early. The development of an aerospace vehicle is a combined effort of many disciplines contributing their know-how and expertise throughout the engineering process. Multiple teams including propulsion, aerodynamics, and systems, explore different variants of the future vehicle to come up with a solution that best balances the set of
multi-disciplinary requirements. The purpose of the exploration design phase is to review and agree on the most optimized component or vehicle configuration as early as possible. The project is expected to produce its first conclusions by the end of 2011.
