Lenovo Ultrabook tries to touch convertible tablet with an interesting concept screen mounted on hinges that allow complete folding of the slab. This format is interesting us he convinced?
In the family of Windows 8 Ultrabooks touch, we tried the ultra-thin (Acer Aspire S7), the sliding screen (Sony VAIO Duo 11), detachable screen ( HP Pavilion DV4 ), but we did not yet tried the screen turns completely to switch to tablet mode. Yet this is the solution adopted by Lenovo IdeaPad Yoga to its range, we were able to get 13'' version, equipped with a configuration high-end (Intel Core i7-3517U @ 1.9 GHz, 8 GB DDR3, 240 GB Samsung SSD).
As such, no worries, of course. Our various performance tests have shown the potential of this hardware, which is a portable powerful and homogeneous, with only gaps will fall next game and heavy 3D applications, because it will then deal with the Intel HD 4000 IGP, rather comfortable on 3D engines a little older and much less to the latest blockbusters. Side and multimedia playback HD video streams, however, no problems. The Compaq Presario CQ60 less well recognized compared to nearly identical configurations can undoubtedly be explained by installing RAM on a single channel.
This point is very fast on the technique, let us more about what makes the difference Yoga 13 with respect to other Ultrabooks touch. Already, before dwelling on its hinges innovative note that the laptop is relatively thin (17 mm) is very well done. All plastics used are treated to give a soft, lightly padded limit, which in addition to being very pleasant to handle, promote ownership of the computer. This is the case outside, above as below, but also on the inside around the Toshiba PA3465U-1BRS keyboard (chiclet and comfortable, but not backlit) where treatment of type "leather" is applied to the plastic. Success undeniably makes up a notch note finish and print quality from the product. Similarly, treatment as "glass" touchpad confirms the positioning high-end of this hybrid.
Finish and ergonomics convincing
The ergonomics of Yoga 13 is generally excellent, and its screen is anything but pliable gadget. Certainly, the concept requires an object to wrestle 1, 5 Kg even use tablet, but it benefits in exchange for a Inspiron 1300 powerful machine, whose autonomy is rather well managed (see dedicated path). And especially, Yoga and folds in most situations, we want to see our family photos, play, work, play ... All has also been thought by Lenovo. For example, the rotation of the screen is perfectly supported, and the keyboard turns off automatically when Yoga is completely folded, to avoid false manipulations. Frankly, it is very pleasant to handle a hybrid machine as homogeneous and offering many possibilities. However, this raises some questions about the strength of the keyboard or hinges on the long term. So keep some reserves, but on our 15-day trial, none of these elements will have shown the slightest sign of weakness, which is reassuring.
The side of the connectivity, the IdeaPad Yoga 13 is essential, and not encumbered - unfortunately - not superfluous. On the left edge, a full-size HDMI output, USB 3.0, 3.5mm jack, and volume control buttons. At right, charger, USB 2.0, SD card reader and a button "Mute". This is because the rear section is dedicated to ventilation (logical given the concept of portable folding in all directions). A fair bit for a machine of this size (33.3 x 22.5 x 1.7 cm 1.54 Kg), which could have been more generous, particularly in terms of USB ports, even if in practice it s 'to accommodate quite well. Do not forget the presence of a Pavilion DV5 module WiFi n and Bluetooth 4.0. In this regard, we note that the speakers are very poor (both in terms of performance and quality of restitution), and the 720p Webcam produces an image very grainy when the light is lacking.
His screen format 13.3'' displays a good definition of 1600 x 900 pixels. It has recently been dealing with tiles of this size in Full HD, very pleasant to use for work, but it appears sufficient resolution, ideal for not damaging the eyes but be entitled to a substantial fine display compared to good old 1366 x 768 pixels that can eventually shaming. Its color balance is not great (Delta E of 6.1 to 5200K) but not catastrophic either, while retaining Dell Inspiron 1525 IPS technology offers open viewing angles, but the brilliant treatment enhances the slightest reflection. Raised the maximum brightness of 212 cd / m2 is a little weak, but the black point of 0.28 cd / m2 puts the balance sheet at the contrast (756:1). The happy owners of a probe will however be delighted to learn that the screen is calibrated perfectly.
Autonomy interesting fan regrettable
If you read the text carefully, you've probably noticed a few negative points, but nothing really crippling. The positive side, adding to balance board battery which four cells has a total capacity of 54 Wh. It is a little more than the best equipped Pavilion DV6 Ultrabooks in the field, which is confirmed in tests of independence. 6:44 in office, 5:14 to 2:33 in video playback and BatteryEater, Yoga 13 holds up in a beautiful way. And most importantly, its battery is charging more than the average, to board from 20 to 80% charge in just 48 minutes. This is not trivial.
