Lenovo IdeaPad S10 4231 review: Lenovo IdeaPad S10 4231

With the exception of the extended battery that sticks out from the rear of the system, the system is physically identical to the Lenovo S10 we reviewed in 2008. We liked the chunky, squared-off design, and the IdeaPad S10's chassis is a little thinner than many of the heftier Netbooks out there--although counting the extended battery, it maxes out at 1.5-inches thick--the same as Asus' 10-inch Eee PC 1000HE.

There's a decent-sized keyboard (for a Netbook), but we're troubled by the right Shift key, which is shrunk down and awkwardly placed directly to the right of the up-arrow key. The touch pad is small but usable, with a similar (but less extreme) wide design to the HP Mini 1000, although in this case, the mouse buttons are below the touch pad, not on either side. The included ExpressCard/34 slot, which is rare on smaller systems, is useful for adding aftermarket extras, such as a mobile broadband modem.

Another new feature is the Splashtop-powered quick-start environment, which gives you access to a Web browser, media files, and other applications before you boot into Windows. These secondary operating systems can be good for saving battery life and quickly getting online without waiting for XP to boot up, but functionality is limited, some configuration options (such as wireless networking) use menus that may be unfamiliar to Windows users, and, in the long run, they usually don't boot up that much faster than just going into Windows.

The 10.2-inch wide-screen display has a 1,024x600-pixel native resolution, which is standard for 10-inch Netbooks. The matte screen is good for avoiding glare, although some more design-oriented Netbooks now offer edge-to-edge screen glass for a slicker look.

With Intel's now-standard 1.6GHz Atom N270 CPU, specifically designed for low-power Netbooks, the Lenovo S10 performed on par with other Atom-powered Netbooks, although it had an edge in our multitasking test. Systems with newer Netbook-style CPUs, such as the HP Pavilion dv2 and Samsung NC20 (with the AMD Neo and Via Nano CPUs, respectively), were faster in single-application tests, such as iTunes.

For Web surfing, e-mail, and working on office documents, which is 90 percent of what most people do on their laptops anyway, Netbooks such as the S10 perform adequately, as long as one's expectations are kept modest.

The original Lenovo S10 offered a disappointing 2 hours and 13 minutes of battery life on our video playback battery drain test, using its three-cell battery. This new six-cell version was much better, scoring 4 hours and 1 minute on the same test. That's a big improvement, and addresses our main problem with the S10. Still, some Netbooks, such as the Acer Aspire One AOD150, can run for even longer.

Lenovo includes an industry-standard one-year parts-and-labor mail-in warranty with the system. A variety of extension options are available and upgrading to a second year of mail-in service costs an extra $49, while three total years of service is $129.
