Lenovo ThinkPad T520i review

Price when reviewed

When most people think of business laptops they invariably think of ThinkPads, as few brands are as consistently reliable as Lenovo’s flagship. The ThinkPad T series is often the best of the lot, and the T520i effortlessly continues that fine tradition.

It’s a traditional 15.6in laptop, and it bears so many of the hallmarks that make the brand so popular: the curved protective lip on the lid and base, the red trackpoint partnered by a trio of dedicated buttons beneath the keyboard, and that instantly recognisable logo in the corner of the wristrest.

It’s classic rather than stylish – especially compared to the A-Listed Sony VAIO S – but the ThinkPad outstrips the dearer Sony when it comes to build quality. That’s in part due to its larger dimensions, as a 15in, 2.9kg laptop is easier to make sturdy than one at 13.3in and 1.69kg. But the construction is excellent throughout: there’s hardly any give in the wristrest and base, and the lid is strong, requiring a hefty prod to produce any show-through on the display.

Lenovo has stuck with a traditional keyboard layout rather than following the current trend for Scrabble-tile keys, and as such it offers a deep, comfortable and responsive typing action. The left-hand side of the keyboard suffers from a slightly bouncy base, but the right side is rock-solid, and we didn’t notice the difference in general use. The trackpad, meanwhile, is modestly sized but paired with clicky, comfortable buttons.

As with the Sony, the T520i’s screen has a matte finish to suit the bright lighting of an office, but the quality is merely reasonable. Its measured maximum brightness of 219cd/m[sup]2[/sup] and contrast ratio of 217:1 are both disappointing, and a decent average Delta E measurement of 6 isn’t enough to prevent the Lenovo from looking pretty pallid and muted on the whole. The native resolution of 1,366 x 768 is also disappointing for a 15.6in laptop. In the Lenovo’s defence, the screen is also the Sony VAIO S’s weakest point, and since neither is meant for entertainment, it isn’t a deal-breaker.
