Dell Inspiron 15-5547 laptop: review and testing

Recently laptop market feels active pressure from the tablets. This is due to the fact that the last has a relatively low cost, compact, long battery life and good functionality and this should be sufficient for most daily tasks (surfing the internet, watching videos, listening to audio, etc.). But if you need a full-fledged mobile x86 system with inherent advantages (high-performance, full keyboard, large screen, a wide range of specialized programs), the laptops are perfectly suitable for this role.

Packaging and content

For testing we have a test sample of the product. It is packed in a normal bag for laptops, rather than the traditional cardboard packaging. Therefore we can not tell in details about the full scope of delivery.

Completion of the test sample Dell Inspiron 15-5547 includes a small power supply unit with cable for connection to the network. In the retail version also you can find the documentation and presence of some additional accessories.

Design, elements layout

Dell Inspiron 15-5547

Generally speaking, the laptop Dell Inspiron 15-5547 is made in the familiar style that allows to determine accurately the manufacturer. This model refers to a completely updated lineup Dell Inspiron 15, 5000, incorporated the features partly inherent in the latest models of lineups Dell Vostro and Dell XPS. The laptop is very different from its predecessors of the lineup Dell Inspiron 15. It is more pleasant visually through more modern and interesting shape of the case, as well as through a noticeable decrease of thickness and weight (21% thinner and 19% lighter than the previous 15.6-inch model).

The housing of the mobile computer is made of black matte plastic. At the bottom is a silver bezel complex form, which comes partly on the edge of the side faces. In the rear part of it is flat, and closer to the face has a tapered shape which visually reduces the thickness of the device.

The base has a removable flat panel (for quick access to the main components of the system), which is held firmly enough with two screws and a number of hooks. The proximal and distal parts are rubber pads on the entire length, which replaces the usual four legs to secure the device on a flat surface. Here is a wide mesh ventilation for fresh air intake.

On the sloped front panel there are two stereo speakers (sent directly to the user) and two LEDs (power and HDD activity). On the rear side is the display unit.

To the left are: security lock Kensington, jack for connection of power adapter, USB 2.0 port and Memory Card Readers (SD, SDHC, SD3.0, MS, MS Pro).

On the right side there are: a combined audio jack (for connecting speakers/headphones or microphone), two ports USB 3.0, HDMI 1.4a port and the network connector RJ45. Optical is absent.

The outer part of the display is covered with a sheet of brushed aluminum with a horizontal texture. Here at the center is a glossy logo of Dell company. Closer to the hinge the lid part is little rounded, and the edges are folded on a path and a little metal covers the sidewall.

Operating panel of laptop Dell Inspiron 15-5547 is made of non-staining practical plastic dark gray with a "spark" (very small inclusions that are original gaming on the light), is quite pleasant to the touch. Here are: power key (without light), which has a clear and tight pressing protecting it from accidental engagement; keyboard unit and considerable touchpad without have no dedicated keys.

At the edge (between the hinge and the base) are holes to output hot air outside the case.

Border around the display is made of glossy plastic, which has some disadvantages. In the top center is the eye a web camera (with LED) and two stereo microphones. On the edge there is another slightly raised bezel (matte). It is designed to protect the display when you close the lid.

The display unit is attached to the base by means of a sufficiently tight shelf hinges. It is possible to open the Dell Inspiron 15-5547 using one hand, although the fixation is reliable. This is facilitated by the size (380 x 259 x 21,8 mm) and weight (2.38 kg) of the device. The maximum opening angle is approximately 135, which is enough for most usage scenarios.

If we talk about the overall stiffness of the structure, it is at a very high level, as well as the quality of the assembly. Laptop is hardly undergoes deformation during attempts to pressure or torsion, and the parts fit together without any gaps.

Input device

Dell Inspiron 15-5547

The model Dell Inspiron 15-5547 has installed full-size keyboard with quite successful and the usual location of the keys. The latter are based on the scissor-membrane mechanism (Scissors System) and have the following dimensions: the letters - 14 x 14 mm; block arrows - 16 x 18 mm; functional series - 12.5 x 8 mm; numeric unit - 12.5 x 14 mm. They are pressed lightly (almost without noise) and have a nice short stroke and tactile feedback. Symbols are applied by laser method and all have white color. This makes them easy to read and should not be erased during a long time.

In addition, using the key combination [Fn] + [F10] you can active the white backlight (there are three brightness levels: maximum, average and zero), which makes it quite comfortable to work in the dark. Besides the keyboard is protected from moisture. The tested model includes Cyrillic.

Working area has quite large size, so for continuous operation of the wrist won’t tire. The basis of the keyboard unit is pretty well fixed. Only under strong pressure it is possible to observe a slight extrusion, and only in the central part.

The touchpad has a considerable size (105 x 80 mm) and dedicated keys, so for some time the user have get to used. Finger sliding across the touchpad is quite pleasant, and the sensitivity is high. There is support of multi-touch gestures. Disabling of touchpad will not available.

It should be noted that there is a modification of laptop with touchscreen, which complements the aforementioned input methods.

Display, webcam and sound

Dell Inspiron 15-5547

Laptop Dell Inspiron 15-5547 is equipped with 15.6-inch display AU Optronics B156XTT with fairly common resolution - 1366 x 768. The matrix is made according to TN+Film technology and has a glossy finish. It is characterized by rather small viewing angles and actively collects dust and can have a hotspot in direct sunlight. However, under normal conditions, the display is characterized by sufficient detail images with natural color reproduction and brightness with considerable margin, although the contrast is at a mediocre level.

We note a rather controversial execution of borders around the display. Firstly, it is glossy, and secondly, hides the real size of the display, which initially seems a little larger than is actually.

Above the display in the center is a webcam with a resolution of 1280 x 720 (HD) and an activity indicator. Its capabilities will be enough for all sorts of web conferencing or video calls. High audio quality is provided by two microphones.

Dell Inspiron 15-5547

The audio subsystem includes two speakers (directed to the user). The role of audio codec performs fairly new Realtek ALC255. There is a support of technology Waves MaxxAudio. In general, the peakers are quite loud and provide good sound quality (even there is a hint of the bass). Capabilities of standard audio subsystem should be quite enough for most everyday scenarios. Otherwise you can connect headphones or external speakers.
