Lenovo ThinkPad X220 review:

Lenovo ThinkPad X220

The Intel Core i5-2520M CPU in our test unit was more than fast enough to make this system stand out. While not as speedy as the quad-core 15-inch Apple MacBook Pro, the X220 did very well in our benchmark tests, beating out most pre-Sandy Bridge laptops, even high-end desktop replacements. If you have any trouble getting the expected performance out of this laptop, do what we did and check all the power settings in the ThinkVantage software and make sure Intel's Turbo Boost Technology is enabled.

With the new Intel platform, you also get vastly improved integrated graphics. Previous Intel onboard graphics could barely play 3D games, but the ThinkPad X220 ran Unreal Tournament 3 at 1,366x768-pixel resolution at 60.2 frames per second, which is more than acceptable for mainstream gaming. Your mileage may vary in newer games, of course, so be prepared to dial back the resolution and detail settings in any laptop without discrete graphics. And besides, this is a business laptop, so you probably shouldn't be playing games on it anyway (or at least don't get caught).

Lenovo has always prided itself on offering excellent ThinkPad battery life, and Intel has made lofty claims about the power efficiency of its second-gen Core i-series platform. Put those together, and battery expectations are lofty indeed. So it's a good thing that the X220 ran for 6 hours and 41 minutes in our video playback battery drain test, which is an excellent score for any laptop, and especially for one that demands no real performance compromises. The 15-inch MacBook Pro ran for about 25 minutes longer, and last year's ThinkPad X201 was also in the same ballpark, but this is still pretty rarefied air.

Lenovo ThinkPads generally include a standard one-year mail-in warranty, which may not be adequate for a mission-critical computer. Trading up to next-day on-site service is $39 for one year or $219 for three years, with several other service tiers and terms available. 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.
