The new Lenovo IdeaPad S405 is so slim and light that you could easily mistake it for an Ultrabook, but it costs hundreds of dollars less. Powered by an AMD A6 processor, this $399 laptop, equipped with Windows 8, promises strong mainstream performance in a sleek design. You also get Dolby-powered speakers. Find out whether the S405 has the right mix of features for your money.
The interior of the S405 is made of a simple, black matte plastic. The only piece of flair is the dark-gray power button, with its spun metal design. Like the S400, the S405's battery sits directly above the keyboard deck as a rather large hump.
Weighing 3.4 lbs., the 13.2 x 9.4 x 0.86-inch S405 is very light for a 14-inch notebook in this price range. By comparison, the Toshiba Satellite L745, another affordable 14-incher, weighs 4.4 lbs. and measures 1.5 inches thick. But that system also has an optical drive.
When we streamed the 1080p trailer for "The Guillotines," details were sharp, but the colors were a little flat. What should have been a huge, red fireball instead took on a faded orange hue. It still managed to draw our eye as it streaked through the pallid blue sky, but the color wasn't as deep as we would have liked.
Viewing angles were rather shallow, with color inverting anywhere past 45 degrees. You also need to push the display back farther than we'd like in order to view content without it washing out.
The S405's bottom-mounted speakers deliver a sizable punch for a budget notebook. The laptop filled our small test room with the funky bass and exaggerated synth from Janelle Monáe's "Q.U.E.E.N." Monáe's mezzo-soprano was crisp and vibrant. The bass could have been stronger, but overall, the Dolby-powered speakers provide above-average audio.
Keyboard and touchpad
Performing multitouch gestures -- such as pinch-zoom, two-finger rotate and three-finger flick -- were quick and responsive on the S405's large 4.25 x 2.75-inch Synaptics touchpad. However, we had to be careful to initiate gestures in the center of the touchpad, or we'd risk accidentally setting off the Windows 8 gestures. Gestures for the Charms Menu and Recent Apps bar were also easy to perform.
The bottom edges of the touchpad performed their right- and left-click duties well, providing a satisfying click when pressed.
After watching 15 minutes of "Code Monkeys" on Netflix at full-screen, the S405's touchpad measured 81 degrees Fahrenheit. That's well below our 95-degree comfort threshold. The space between the G and H keys and the bottom of the notebook were nearly as cool, at 83 and 85 degrees, respectively.
The Lenovo IdeaPad S405 features a 2.1-GHz AMD dual-core A6-4455M Accelerated Processor with 4GB of RAM, which gives enough oomph to tackle low- to mid-level productivity tasks. An episode of "Samurai Jack" streamed smoothly, even with six open tabs in Internet Explorer, Mozilla Firefox and Google Chrome, while performing a full system scan.
The S405's 500GB 5,400-rpm hard drive booted Windows 8 in 21 seconds, blowing past the 41-second average. The Q200 and the Sleekbook 15z, which also have 500GB 5,400-rpm hard drives, clocked in at 23 seconds and 18 seconds, respectively. During the File Transfer test, the S405 duplicated 4.97GB of multimedia files in 3 minutes and 19 seconds, a transfer rate of 25.6 MBps. That's short of the 40 MBps category average but better than the 15z (22.9 MBps) and Q200 (21.4 MBps).
When we ran the OpenOffice Spreadsheet Macro test, the S405 matched 20,000 names to their corresponding addresses in 8 minutes and 59 seconds. That's slower than the 5:39 average, but much faster than the 11:29 and 10:12 that the Q200 and 15z posted.
The Lenovo IdeaPad S405 has an AMD HD 7520G GPU, which enables users to play casual games and high-def videos. When we ran the 3DMark11 benchmark, the notebook notched a score of 560, falling short of the 709 category average. However, its score was high enough to beat the HP Pavilion Sleekbook 15z's AMD HD 7500G GPU, which scored 468. The ASUS Q200, which has an Intel HD Graphics 3000 GPU, and does not support DirectX 11, could not run the test.
During the "World of Warcraft" test, the S405 delivered an average of 28 frames per second at 1366 x 768 on Good, which is just below what we consider playable -- 30 fps. Both the Q200 and Sleekbook 15z fell behind, with 12 fps and 24 fps. When we switched the settings to Maximum, the S405 notched 14 fps.

Other branded apps include SmartUpdate, which automatically updates email and social networking messages in designated intervals, even while the system is in Sleep Mode. DIYers can use Lenovo Photos to make their own photo books, cards and invitations. There's also Photo Show for editing your pics.
Third-party options include the Rara music service and PDF-maker Nitro Pro 7. There's also Evernote and AccuWeather.com. You'll find Skype, LenovoCloud Storage by SugarSync and Microsoft Office 2010, but you need a key to activate the latter.
