Lenovo is known for its high-quality business
Design
It's hard to do justice to the design of the U400 using words alone, because this laptop is one you have to touch and feel to fully appreciate. The chassis is made from a single sheet of gray aluminum, molded seamlessly like the unibody design of the
This aspect has been extended to every element of the laptop. The touchpad's glass surface feels silky smooth and almost soft; this is the first time I've been loath to pull my fingers away from a touchpad. The keyboard is just as nice: Unlike the square tile keys popularized by Apple, Lenovo uses a scalloped variation of the chiclet keys; they travel smoothly, with just the right combination of firmness and give, and feel almost as luxurious as the touchpad.
The underside of the chassis is as smooth and clean as the lid, without even a vent to disrupt the surface. That's because Lenovo has used a new cooling system that utilizes a breathable keyboard as the primary air intake. A small vent on the left side of the chassis is the only one you'll see, but there are others concealed in the hinge. The result is what Lenovo calls a "pillow-proof" ventilation system—with no bottom vents to obstruct, you can set the laptop on a pillow without having to worry about it overheating.
The U400 utilizes the same book-cover design seen on its ultrabook sibling, the
The Lenovo IdeaPad U400 has a 14-inch screen, with 1,366-by-768 resolution. That doesn't top the 1,440-by-900 screen of the recent 15-inch Apple MacBook Pro , it's more than sufficient for browsing the Web, streaming 720p video, or multitasking with side by side windows.
Features
The features found on the Lenovo IdeaPad U400 are on par with the best mainstream laptops we've seen recently, like the Apple MacBook Air or Dell XPS 14z . Like these other thin laptops, the IdeaPad omits a few ports to maintain its thin profile, but most people won't miss the VGA or eSATA ports. What you will find are three USB ports, two USB 2.0 and one faster USB 3.0, along with a headset jack and Gigabit Ethernet port. A slot-loading DVD±RW burner maintains the chassis' clean lines, and an HDMI port lets you connect the laptop to a monitor or HDTV. If you want to ditch the cable entirely, the IdeaPad U400 also has WiDi 2.0, a wireless streaming technology that uses the
Our review unit came equipped with a 750GB 7,200rpm hard drive, which is similar to the 750GB drives found in the recent Dell XPS 14z and the
Performance
Lenovo has outfitted the IdeaPad U400 with 6GB of RAM and a 2.4GHz Intel Core i5-2430M, a dual-core, four-thread processor similar to those found in the
The IdeaPad U400 will also make a good addition to the arsenal of anyone who works with photos, video, or graphic design. It made short work of our Handbrake (1 minute 59 seconds) and Photoshop (4:08) tests. These aren't the fastest results of the bunch—those belong to the MacBook Pro (Handbrake 1:30) and XPS 14z (Photoshop 3:27)—but they're within spitting distance.
One of the few areas where the IdeaPad U400 fell behind was 3D graphics. Equipped with switchable AMD Radeon HD 6470M graphics processing, the Lenovo produced 3DMark 06 scores of 4,835 at 1,024-by-768 resolution and default detail settings, and 3,478 when turned up to 1,366-by-768 resolution and enhanced details. Even with discrete graphics, the IdeaPad couldn't match the high-octane results seen in the Samsung Series 7 (10,807 points at 1,024 by 768) and MacBook Pro 15-inch (11,180 at 1,024 by 768). The IdeaPad U400 also fell behind in gaming, turning out barely playable frame rates in Crysis (31.5 frames per second, or fps) and unplayable frame rates in Lost Planet 2 (15.6fps). There's a lot you can do with the Lenovo IdeaPad U400, but high-performance gaming isn't on the list.
One method used to keep the chassis slim is to seal the battery within, with none of the bulk added by a release mechanism. It's a design decision we've also seen on the Apple MacBook Pro and the Dell XPS 14z, and just as with those laptops, you won't be able to access the IdeaPad's battery to swap it out. Thankfully, the U400's 54Wh battery lasted a full 6 hours in our MobileMark 2007 battery test. This time is comparable to both the Dell XPS 14z (6:03, 58Wh) and HP Envy 14 (5:15, 56Wh), but it's easily beaten by the larger, longer-lasting Dell Inspiron 14z (8:38, 65Wh).
The Lenovo IdeaPad U400 brings luxury to the mainstream laptop, combining a design that looks good and feels even better with solid performance and features like USB 3.0 and WiDi 2.0. In terms of performance, it's an excellent alternative to our Editors' Choice Dell Inspiron 14z (Core i5), but it can't compete on price. You'll be hard pressed, however, to find a more touchable competitor.
