Lenovo ThinkPad W520 Review: First Thoughts


What do you turn to when a standard notebook just won't cut it in the performance department? Well you could try lug a desktop around with you... or you could turn to a business-class workstation notebook. Today we take a quick look at the new Lenovo...

To thoroughly test the workstation-class Lenovo ThinkPad W520, we expect the full reviewing process will probably take another week or two until our tests are finished and verified. As we mentioned above, the review will be including workstation-spec...

Lenovo ThinkPad W520 (428426M) mobile workstation


Lenovo ThinkPad W520 (428426M) review: A semi-rugged laptop that's designed for professionals

Excellent screen quality ; Chassis is very sturdy ; Good performance

Touchpad could be better ; Lid could be more rugged ; Only 1-year warranty as standard

The ThinkPad W520 isn't a typical laptop. It should only be considered if you're a professional in need of a strongly-built and well-performing laptop that can help you get your work done efficiently. It's not perfect, but it has stacks of features and...

Lenovo Does Not Support Customers


Do not purchase from Lenovo unless you have strong internal hardware support staff and a dedicated person to manage communications with Lenovo. If you have issues with CS, press to speak with supervisors and express concern with their process....

This particular model has some good functioning features great for those working with legacy software and hardware. Nice to get Win7Pro as an option

Lenovo Customer Support, particularly on the sales side, is grossly inefficient. None of the people you talk to when calling them with issues has real authority to help you. This can be very frustrating if you are an individual or a small business....
