This isn’t a full-size laptop so we can describe it as a mini laptop, or better said, an ultrabook as the manufacturers prefer to market non full-sized laptops that come with powerful hardware specifications. First, let’s talk about the design of the Lenovo IdeaPad U400 and mention that its chassis is manufactured from a sheet of gray aluminum which is molded seamlessly much like the unibody design that you’ve seen on the MacBook Pro from Apple.
The touchpad of the U400 has a gloss surface which feels buttery smooth and soft, a touchpad that even those who prefer an external mouse will like. We have good things to say about the keyboard as well which adopts a scalloped variation of the chiclet keys, offering a good amount of travel and firmness, managing to feel just as premium as the touchpad.
The Lenovo IdeaPad U400 has a “pillow-proof” ventilation system that doesn’t have any bottom vents to obstruct, which means that you can put the ultraportable on a pillow and it will not get hot, hence the name. This model has a book-cover design which means that instead of the clamshell or wedge shape seen on a lot of today’s laptops, this one has a flat profile, with the edges of the bottom and top lids protruding slightly, much like a book’s covers. The U400 measures 0.89 x 13.38 x 9.05 (HWD) and tips the scales at 4.25 pounds.
It comes with a 14-inch display that has a native resolution of 1,366 x 768 pixels which is suitable for 720p videos, surfing the Internet and multitasking with side by side windows. It comes with three USB ports (two 2.0 and one 3.0), an Ethernet port and a headset jack. There’s also a slot-loading DVDRW and an HDMI port for connecting the ultraportable to an HDTV. We should also mention that the Lenovo IdeaPad U400 comes with WiDi 2.0 for streaming video content wirelessly but you’ll need to get the Netgear Push2TV adapter. Also on board you will find Bluetooth 3.0 and 802.11n Wi-Fi.
The ultraportable is powered by a dual-core, four-thread Intel Core i5-2430M processor clocked at 2.40 GHz and comes with 6GB of RAM. For storage you get a 750GB hard drive spinning at 7,200 rpm and on it you’ll find Office 2010 Starter, Absolute Data Protect, Microsoft Security Essentials, Google Chrome, Lenovo OneKey Recover and Lenovo Enhanced Experience Boot Optimizer.
One of the methods used by Lenovo in order to keep the U400’s chassis slim was to seal the battery within. Its 54Wh battery is capable of surviving for about six hours during a demanding MobileMark 2007 test, on par with other models that belong to the ultrabook segment.
