Samsung Series 9 Np900x4c is good looking laptop and with a good specification and by design it The new NP900X4C is essentially a processor update of the Samsung Series 9 15-inch (NP900X4B-A02US).It has the same 0.6-by-14-by-9.3-inch (HWD) measurements, and weighs the same (3.6 pounds). The system has a travel weight of 4.3 pounds with the AC adapter, which makes it slightly lighter than the Apple MacBook Pro 15-inch (Retina Display)(4.4 pounds). It's an ultrabook with desktop replacement dimensions, thanks to its 15-inch screen. That screen is bright, with a decent if underwhelming 1,600-by-900 resolution that's fine for viewing 720p HD content. But 15-inch laptops are aimed at people who want to display more information on their screens, like photographers and Web developers, and the 1,600-by-900 resolution may be too small for that. After all, the high-end ultrabook Editors' Choice–winning Asus Zenbook Prime UX32VD-DB71 $1,099.00 has a 13-inch 1,920-by-1,080-resolution (1080p) screen in a much smaller package. Ultimately it's in the middle: better than the 1,366-by-768 resolution found on most systems, but you really want a higher-resolution screen to match the physically larger screen.
The keyboard and touchpad remain virtually unchanged on the 15-inch Series 9. The travel of the keys is still shallow, and although we were able to achieve a rate of 68 words per minute with an error rate of 1 percent on the Ten Thumbs Typing Test (slightly above our average speed), the island-style keys offered only a mediocre amount of tactile feedback.
Thankfully, Samsung has improved the backlighting. In a completely dark room, we were able to clearly make out individual keys, although the 400-nit SuperBright display illuminated the keyboard so thoroughly that the backlighting seemed almost superfluous.
The 4.3 x 2.9-inch touchpad is just as spacious as before, and features much improved performance. The cursor glided smoothly and accurately across the screen, and clicks registered throughout the surface of the pad, rather than just the lower third. Multitouch gestures such as pinch-to-zoom and three-finger-swipe proved equally reliable.
Watching the trailer for "The Dark Knight Rises" proved as much of an auditory experience as a visual one. Turning up the volume to the maximum, Hans Zimmer's swelling orchestral track filled the room. With no subwoofer, the Series 9 lacks some of the "oomph" of thicker notebooks such as the XPS 15, but it manages to maintain accuracy even at full volume.
With the NP900X4C, Samsung managed to make the 15-inch Series 9 run just a bit cooler. After streaming video for 15 minutes, the touchpad registered 78 degrees Fahrenheit (compared with 83 degrees on the previous generation), the space between the G and H keys was 90 degrees (previously 94 degrees) and the underside measured 92 degrees (previously 95 degrees).Port selection remains the same as on the previous Series 9 15-inch. The NP900X4C boasts two USB 3.0 ports, a powered USB 2.0 port and a 4-in-1 (rather than 2-in-1) card reader.The notebook also sports a micro Ethernet port (an adapter is included in the box), microHDMI port and mini-VGA port (no adapter included), as well as a combo headphone/mic jack.Using the bundled CyberLink YouCam software, the 1.3-MP webcam captures stills and video at a maximum resolution of 1280 x 1024, although video suffers from a bit of lag when filmed at this resolution. Still, the camera rendered colors accurately and crisply.
Regrettably, the Wi-Fi performance has proved to be less good than on my NP900X3B (which in turn is less good than the Dell E6410 and Lenovo T420s that I have tried in the same location at the point in my house most remote from the router. I had to set the power to maximum to be able to hold a connection at the other end of my house. Even then, the speed is disappointing. I have tried all the Wi-Fi options I can find in the search for improvements. The antennae arrangements in both notebooks are similar and are located at the back edge of the chassis between the hinges where the casing is plastic, not metal. However something has changed for the worse, at least on my computer (other NP900X4C owners are not complaining of this problem). The new model has the Intel 6235 Wi-Fi/ Bluetooth combo card while the older notebook has the previous Intel 6230 card with similar features. I hope that a driver update will improve the situation but wonder if the antenna module is sub-standard.
