Lenovo ThinkPad E220s review: Lenovo ThinkPad E220s

The 1.4GHz Core i5-2537M CPU in the ThinkPad Edge E220s is the same processor we tested in the Samsung Series 9. It's a low-voltage CPU, amounting to a slower experience than on regular standard-voltage Core i-series processors, but it's a second-generation Intel Core i5 processor, which affords it integrated graphics and battery-extending advantages. We found the E220s to perform admirably, despite the low-voltage CPU. In fact, in our benchmarks, it was a faster laptop than the Samsung Series 9. Multitasking, HD video streaming, and other processor-intensive tasks are pulled off well enough to not feel hindered by the CPU choice. When we reviewed the similar-size IdeaPad U260, it featured last year's low-voltage Core i5 CPU, and we found it lacked a little punch. This Edge E220s gives a faster, better experience. Alternatively, you could upgrade to a 1.5GHz Core i7-2617M CPU on Lenovo's Web site for an extra $70.

Speaking of faster, the E220s comes with "Lenovo Enhanced Experience 2.0," Lenovo's branded tweaking of the CPU for better performance. It's hard to tell what it exactly provides, but bootup times seemed a little better than on the average Windows laptop.

The Intel HD 3000 integrated graphics offer some onboard horsepower for gaming and GPU-intensive tasks, too. Unreal Tournament III played at 42.3 frames per second at 1,366x768-pixel resolution and medium graphics settings. That's no better than bearable, but from a laptop this size, few would expect anything much better.

With its non-removable six-cell battery, the ThinkPad Edge E220s lasted 4 hours and 11 minutes in our video-playback battery drain test. We'd expect something higher for a low-voltage laptop, especially since the Samsung Series 9 (albeit, with an SSD) lasted over an hour longer. However, the Edge E220s outperformed the disappointing IdeaPad U260, proving the value of a second-generation CPU. Its battery outlasted the ThinkPad X1's internal six-cell, but that should be no surprise, as the X1 tested packed a standard-voltage processor. More than 4 hours should get most people over the hump into an acceptable range of battery life, but there are plenty of options (the MacBook Air, the Toshiba Portege R835) that will do better.

Lenovo offers a standard one-year warranty with the ThinkPad Edge E220s. That warranty can be upgraded up to three years when ordering on Lenovo's Web site, along with adding extra service options such as priority on-site care and accidental damage protection. In addition to the onboard ThinkVantage troubleshooting and driver update apps, the Lenovo Web site offers the same information, but an actual tech-support contact number can be hard to find (although chances are your company IT team would handle any problems with the system). If you do need to call Lenovo, try this 24-7 support line: 1-800-426-7378.
