Lenovo is going very better when its about laptops/Notebook and they produces such nice and performance laptops and they always treid to do so and mostly they succeeds and this time lenovo thinkPad u400 is on the table and we saw it 1st time it does looks much different then their most lenovo laptops looks.The U400’s case is built entirely from aluminum -- having an all-metal body provides some obvious benefits when it comes to durability, and its sturdy construction shows few signs that shortcuts were taken.There’s no flex in the body and unlike many other consumer-targeted notebooks, the U400’s build quality is virtually flawless -- we saw no signs of construction errors such as sticky touch pads or misaligned casing gaps. On every possible surface of the U400 — including the keyboard deck, monitor hinges, and display lid — we had no issues with parts feeling loose or flexing significantly. In addition, the U400’s display eschews the usual rubber stoppers for a discrete rubber ring around the screen’s perimeter.Aesthetically, the IdeaPad U400 even calls to mind laptops such as the Apple MacBook Pro or HP’s Envy series. With its rounded corners and svelte edges, the laptop’s industrial chic brushed metal look gives it an elegance that is refined without being overbearing.The bottom of the case offers little of note. As most of the U400’s cooling needs are served by a side fan grille and a ventilating keyboard -- air is circulated through the keyboard to cool off the notebook’s internal components -- the bottom doesn’t feature any secondary fans or grilles. In addition, there are no rear protrusions from the battery since the battery fits within the dimensions of the U400.However, the U400 throws up some significant roadblocks for users who enjoy upgrading their own notebooks. The laptop’s only screws are hidden underneath the glued rubber pads on the U400’s underside and according to several users on Lenovo’s forums, it is extremely difficult to reassemble the U400 afterwards. We’re sure that enterprising U400 owners are already figuring out ways to disassemble and reassemble the notebook, but for layman users who simply want to upgrade their own hard drive or add more RAM.14-inch, 1366 x 768 glossy display on the U400 is just average. Colors were plenty vivid when watching a 1080p trailer of Mission: Impossible streamed from YouTube, but we noticed a good deal of splotchiness in darker areas. We also found viewing angles to be somewhat limited; images started washing out when we sat on either side of the display. the U400 keeps its internals cool by drawing air in through its "breathable" keyboard and out through the vent on the left side and rear hinge. This managed to keep the laptop relatively cool. After streaming a Hulu video at full screen for 15 minutes, the touchpad was a chilly 78 degrees, the G and H keys measured 89, and the middle of the underside was 90.U400’s approach towards available ports is similarly minimalistic, but whether or not this could also be considered stingy would likely depend on your usage patterns. The notebook touts a basic connectivity selection, including a single USB 3.0 port, a slot-loading DVD drive, HDMI support, and an integrated button for Lenovo’s OneKey Recovery — a bundled program for system backup and recovery maintenance. Ample space between ports makes tangled cables a non-issue and we saw no problems when testing out the U400’s HDMI port.If you're not a thin-is-in type, then the U400 will provide you with much the same experience as its U-series brethren in terms of aesthetics, typing, and pointing. It's fast enough for most purposes, and you get a larger 14-inch screen. It's a tad pricey for an all-purpose, but you always pay extra for style, and this unit has it in spades. Lenovo made this laptop with some great features and with few bad things as well so let put a full stop at theory.
