Heat and Noise
The E220s is basically silent during normal web browsing or using Microsoft Office. Its single cooling fan pushes hot air out the exhaust on the right side of the chassis; the heat only becomes noticeable if you block the exhaust or stress the processor with HD video editing or gaming. At maximum speed the fan in our review unit produced a weak high-pitched whine but it wasn’t loud enough to be disruptive in a typical office or classroom environment. The fan does a good job keeping the notebook cool; the area around the vent on the bottom of the notebook is the only area that gets warm. All exterior temperatures shown below are listed in degrees Fahrenheit.

Battery Life
We measured a rather unimpressive four hours and 48 minutes of battery life during our battery rundown test (Windows 7 Balanced power profile, 70% screen brightness, wireless active, and refreshing a web page every 60 seconds). This is better than the battery life from the similarly sized Lenovo IdeaPad U260 but it’s barely more than half the battery life of the ThinkPad X220.

Again, keep in mind that the E220s’ battery is non-removable similar to Apple MacBooks or the Alienware M11x. Once the battery is drained you have to find a power outlet because you cannot simply put in a spare or attach a battery slice.

Battery life test results (higher scores mean better battery life):

The Lenovo ThinkPad E220s is a reasonably attractive and well-equipped 12-inch laptop for average consumers and small business professionals. This laptop has its share of flaws, but the flaws are largely minor considering the fact you can buy this thin and light notebook for less than $650 online.

Less than five hours of battery life while web browsing is below average these days and you can’t swap batteries on your own. The lack of USB 3.0 combined with the quirky touchpad are also issues that I hope Lenovo addresses in next year’s model.

The biggest problem for the E220s might actually come in the form of Lenovo’s own ThinkPad X220. For just $220 more than the base price of the E220s you can buy the vastly superior X220. The E220s is indeed a nice laptop, but if you’re a business professional I’d have a hard time recommending this laptop instead of the ThinkPad X220 unless your budget is limited to $700.
