Let\’s start the week with the test of the HP Pavilion 15-cw, a 15-inch ultrabook accessible under AMD Ryzen 5 which is installed in a modern and pleasant chassis with a discreet operation. But the performance is not up to the expectations of the tester …

Chassis / Aesthetics
The design of this new generation of Pavilion has been subtly revised and corrected. The sharpened beveled sides, the refined screen borders, the “recessed” keyboard in the base and the graphic design of the speaker grille give a very successful impression of modernity. The case is made of sandblasted metal on the back of the lid and around the keyboard. It thus gains stability even if the rest is plastic and bends a little more under pressure. All surfaces leave almost no fingerprints. The hinge will allow the opening of the lid to raise the base for a more ergonomic typing and better air circulation under the base. The negative point of this system: the opening angle of the
With its 15 inches and its footprint of 36.16 x 24.56 x 1.79 cm, the Pavilion is in a good position compared to its direct competitors. HP can also reduce weight by 200 to 300 grams, making it the lightest unit in its class.
Well-dispersed on each side, the interfaces include an HDMI output, a Gigabit Ethernet port, a USB 3.1 Type-C port, two USB 3.1 ports, an SD card reader and an audio jack. No biometric reader on the menu.
In order to reach the internal components, the entire back of the HP Pavilion 15-cw must be removed.
Keyboard / Touchpad
The keyboard is well designed and conducive to prolific writers. Each key has a clear and precise feedback, a respectable size and a short race but not too much. A white backlight on one shade highlights the silvery touches but it only serves in the dark. For its part, the touchpad is wider than usual. It is sensitive on all its surface and reacts well to the gestures multi-touch. The buttons integrated in the clickpad are quite precise, nothing more.
The HP Pavilion 15-cw incorporates an IPS AU Optronics panel (AUO23ED). This 15.6-inch Full HD screen (1920 X 1080 px) suffers from a low brightness (187 cd / m²). On the other hand, the contrast ratio is much more satisfactory (1240: 1) with deep blacks (0.15). The color is rather average with 55% covered sRGB space and a Delta E greater than 5. Good point, visibility in direct light is good despite the low brightness of the screen. We say thanks to the IPS slab and the matte coating.
Built around a state-of-the-art Ryzen 5 AMD Quad Core, 8 GB of RAM and a dedicated 512 GB SSD, the model tested is suitable for everyday multimedia use. In principle, this processor is supposed to match an Intel Quad Core i5-8250U but the various tests have revealed a serious effect of “throttling” (sudden drops in CPU frequency) which greatly limits its capabilities. In current use that said, the system is perfectly responsive thanks to its good amount of RAM and SSD and all office and multimedia tasks are performed without shaking.
The graphics part Vega 8 is integrated into the processor and does not make all its power available either. The tested HP could not launch any game under correct conditions in Full HD.
Temperatures / Noise
The ventilation runs continuously with a constant noise level around 31 dB (quiet and simple office) that increases only 2 small decibels when the PC is pushed to its limits. It is a beautiful feat. However, a downside concerns the frequency of these fans, a little higher than the average, which can disturb the most sensitive of you. The temperatures are perfectly well dissipated inside and outside the chassis.
With a medium capacity battery (41 Whr), it was not necessary to expect much of the autonomy of this HP Pavilion 15-cw, especially with the AMD architecture known for its higher energy consumption than Intel. Here, you can hope to keep 5 hours in Internet browsing with active Wifi.
