Lenovo IdeaPad U400 review

 

The Lenovo IdeaPad U400 laptop offers a great combination of style, performance, and superior input ergonomics. It's part of Lenovo's U series (U as in ultraportable), but at 22.6mm thick and close to 2.7kg with the AC adaptor, the U400 is more aptly...

If you're not a thin-is-in type, then the Lenovo IdeaPad 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....

Lenovo IdeaPad U400 review

 

The U400 combines a lightweight design with discrete graphics -- something we rarely see -- but its flaky trackpad, crowded keyboard and lack of truly automated graphics switching make it tedious to use.

Lenovo IdeaPad U400 review: Lenovo IdeaPad U400

 

Lenovo IdeaPad U400

The Lenovo ; has a sleek, attractive metal design and a good assortment of features for its price, including a slot-loading DVD drive and AMD graphics.

There's not much that stands out performance-wise over the competition; it lacks the exceptional battery life, higher-res screen, Blu-ray drive, and SSD upgrades that high-end competitors tend to have.

Adopting the looks of an ultrabook and an Apple MacBook, the IdeaPad U400 wins on design and overall value, but it's not that far above other equally good laptops that are out there right now.

Lenovo IdeaPad U400 Review: Stylish, Capable, and Affordable

 

The Lenovo IdeaPad U400 laptop offers a great combination of style, performance, and superior input ergonomics. It's part of Lenovo's U series (U as in ultraportable), but at 0.9-inches thick and close to 5 pounds with the AC adapter, the U400 is more...

Attractive ; Integrated DVD drive

No legacy VGA output ; No Blu-ray option

You won't find a more stylish or capable all-purpose laptop, though it needs a Blu-ray option.

Lenovo IdeaPad U400

 

The Lenovo IdeaPad U400 laptop combines solid performance with a design you won't be able to keep your hands off of.

Design looks good and feels great. Keyboard and mouse are top-notch.

Mediocre graphics performance.

Lenovo IdeaPad U400-09932DU Laptop Review

 

Eye candy. The Lenovo IdeaPad U400 features one of the better-loo

Great case; Compact power adapter

Average benchmark performance; Hard to manually upgrade; Middling display performance

An AC adapter that didn't look clunky, and an all-aluminum exterior at this price point.

Lenovo IdeaPad U400 Review: The Latest MacBook Pro Challenger

 

The 14-inch all-metal IdeaPad U400 is an impressive MacBook Pro competitor that offers good performance and six hours of battery life for $879. Keep reading to find out if Lenovo can deliver a killer premium notebook at a fair price.

Good build quality ; Good battery life ; Solid overall performance

No keyboard backlighting ; Anemic display ; No media card reader ; Not user upgradeable ; The Lenovo IdeaPad U400 offers good looks and good performance at a fair price, but an average screen and lack of media card reader might kill the deal.

Lenovo IdeaPad U400 Review

 

This week we've got the newest offering in the ultraportable PC space with the Lenovo IdeaPad U400 sitting on the review block, and with its simplistic appearance, Core i5 processor inside, and classic "breathable" Lenovo keyboard, we've got what would...

For those of you with a specific use-case in mind, be sure to comment below and I’ll let you know if I think this computer is the one for you or not. For me, it’s simply not the perfect combination of thin, light, and powerful. While it does have the...

Lenovo IdeaPad U400 Review and Ratings

 

This sharp-looking, metal-finish laptop has many valuable features and runs well, but a finicky touch pad and a lack of impact from its graphics hardware suggest it isn't quite as refined as it looks.

Great Webcam and sound system ; Strong performance ; Gorgeous polished-aluminum case

Finicky touch pad ; No perceptible processing boost from discrete graphics ; Small, cramped keyboard

Despite the disappointing lack of impact from the off-board graphics accelerator, the IdeaPad U400 performed as expected on our tests. Its screen's viewing angles are narrow, however, especially when we viewed videos and photographs. To see this type...
