Certainly less attractive than a Zenbook, the Vivobook still offers a very correct finish and a pleasant user experience. It includes an Intel Core i7 processor, 8 GB of RAM, a 15.6-inch display, a GeForce MX 150 graphics chip, a 128 GB SSD and a 500 GB hard drive. A well-balanced computer that fills perfectly his contract.
Visually, the Asus Vivobook S15 looks a lot like a high-end PC, with its brushed aluminum chassis the most beautiful effect. Aluminum is present on the hood behind the screen, but replaced by plastic on the keyboard part.
A high-end appearance that unfortunately does not look once in hands, the chassis crunching under the fingers. Nevertheless, we are still far from an entry-level finish, the Vivobook still offering a more than correct design.
The keyboard is correct, but not exceptional. With a relatively good short stroke and significant resistance, the keys suffer from a certain fragility of the plastic chassis, which tends to bend during writing. The trackpad is very correct and has a built-in fingerprint sensor.
The connector offers a Type-C USB port, three USB 3.0 ports as well as an SD card reader, in addition to the traditional mini-jack audio jack.
As for heating, this Vivobook is in the current average. During our usual test protocol ( Unigine Heaven benchmark for one hour), the ventilation grid under the PC is mounted at 45 ° C. A controlled temperature that allows to work with the laptop on the knees, and without an exaggerated fan blast; the PC does not exceed 40 dB, which makes it almost inaudible in a classic room.
The Asus Vivobook S15 is equipped with a 15.6-inch (1,920 x 1,080-px) matte IPS display. The ratio screen / facade is relatively high (81%) because of the reduced vertical edges. The top edge is wide enough to fit the webcam.
This screen is very correct under the lens of our probe, but it is handicapped by a relative respect for colors, visible to the naked eye – the pure blue displayed are almost fluo – and confirmed by the high measure of delta E ( average of 6.3). It is all the more unfortunate that the color temperature is measured at 6,428 K, almost the video standard (6,500 K). The contrast reaches 1 296: 1 and makes it possible to distinguish the shades of gray. The brightness (275 cd / m²) is average and allows good readability outdoors.
The Vivobook S15 has an Intel Core i7-8550U processor backed by 8 GB of RAM. A powerful processor that promises the user a very comfortable experience. The storage is entrusted to a 128 GB SSD for the system, supplemented by a 500 GB hard disk.
After our usual test protocol (photo, video, audio compression) the Vivobook reaches the index of 149 on our scale of values. An excellent rating that ranks it among the most powerful laptops on the market. It makes it possible to run problem-free computer software without problems.
It should be noted that this Vivobook is equipped with a GeForce MX 150 graphics card. If it does not allow to play the latest games of the moment in ultra settings, it still makes it possible to turn this PC into an extra game machine. Thus, it is possible to play Overwatch at almost 60 fps by setting the graphics to medium.
MOBILITY / AUTONOMY 3/5
With a weight of 1.5 kg and a thickness of 17.9 mm, the Vivobook S15 is easily transportable, especially with its small loader.
In our usual test of autonomy (Netflix under Chrome, brightness set to 200 cd / m², headphones connected), the Vivobook was a little disappointed, since it went out after 6:41. A disappointing score for this type of PC, although it should be more forgiving with the 15-inch format.
The Vivobook S15’s speakers are placed under the chassis and direct the sound towards the torso of the user. This unfortunate placement stifles the sound when you put your wrists on the laptop and the perceived sound source gives the impression of being too far from the screen. The sound itself is correct, despite a very high distortion in the bass and midrange up to 700 Hz. Nevertheless, the human voices are intelligible and the musical listening remains possible. Last point, as annoying as usual: this PC embeds embedded audio software (AudioWizard) very difficult to find, and therefore to disable.
The measurements taken on the headphone jack are for their part very correct, with the exception of the power, extremely low. As a result, it is difficult to connect a headphone power hungry ( monitoring or hi-fi), the latter can not then achieve a sufficient noise level. A real handicap for a laptop. It will be necessary to take care to use a nomadic helmet rather sensitive.
