The Dell Inspiron 15 lineup includes laptops packed with the latest technology. They provide solutions to any problem and allow you to cope with various applications. In addition, laptops have extensive customization options that can be adjusted to suit your own needs.
The whole range of qualities of laptop computers would seem to make them the most acceptable solution for businessmen, but as statistics show, purchasing laptops to replace desktop computers is widespread. Despite the fact that in general desktops are an order of magnitude more powerful and cheaper, ease of use and the ability to carry the device at least within the home often play a decisive role in the choice.
general information
Touch screens are becoming more widely used every day. They are also reflected in laptops. Today, a device with such a screen, by definition, cannot be budget. Therefore, it may seem that in this case there are only two options: either a significant increase in price, or the presence of a minimum number of characteristics. But the manufacturer managed to do the impossible, combining excellent technical performance and reasonable cost in one device.
A special place in the model range is occupied by a laptop with a 15-inch diagonal Dell Inspiron 15 3000 series. The device has powerful functionality. This model can rightfully be considered universal. It is equipped with features that support rich multimedia capabilities.

Hybrid laptop Dell Inspiron 13 7347
In this article, we'll be looking at the relatively inexpensive 13-inch Dell Inspiron 13 7000 Series 2-in-1 Hybrid Laptop/Tablet. Let us clarify that this laptop was inexpensive before the collapse of the ruble, but today it can only be called inexpensive in comparison with other mobile solutions.
As follows from the information on the manufacturer's website, there are several possible configurations of the Dell Inspiron 13 7000 series 2-in-1 laptop, which differ in processor type, memory size, screen resolution and storage capacity. In our case, we will talk about the younger model - Dell Inspiron 13 7347.
Options and packaging
The Dell Inspiron 13 7347 laptop (like all Dell series laptops) comes in a simple cardboard box with a handle. The delivery set is standard for Dell laptops. In addition to the laptop itself, the package includes only a power adapter, a warranty card and a quick user guide.

So, the basis of the Dell Inspiron 13 7347 laptop is a dual-core Intel Core i3-4010U processor. This processor has a clock speed of 1.7 GHz and does not support Turbo Boost. Its L3 cache size is 3MB and its rated maximum power is 15W. The processor supports Hyper-Threading technology.
This processor integrates an HD Graphics 4400 graphics core with a base frequency of 200 MHz and a Turbo Boost frequency of 1.0 GHz.
Let us recall that Haswell U series mobile processors are SiP (System-in-Package), that is, they combine both the processor with the graphics core and the chipset in one package.
According to information on the manufacturer's website, Dell Inspiron 13 7000 series laptops can also be equipped with a more powerful Intel Core i5-4210U processor.
This laptop does not have any discrete graphics card, which, in principle, is quite typical for this class of devices.
The Dell Inspiron 13 7347 laptop comes with 4 GB of DDR3L-1600 memory. Moreover, the laptop itself has only one SO-DIMM slot for installing a memory module. In our case, the SK HynixHMT451S6BFR8A-PB memory module with a capacity of 4 GB was installed in the laptop. The memory, naturally, worked in single-channel mode.
Note that Dell Inspiron 13 7000 series laptops can be equipped with 8 GB of memory.
The storage subsystem in the Dell Inspiron 13 7347 laptop is one HDD Seagate ST500LT012-1DG142 with a capacity of 500 GB (5400 RPM, SATA-II). Note that Dell Inspiron 13 7000 series laptops may have other data storage subsystems, but the drive itself is only an HDD with a capacity of up to 500 GB.
The communication capabilities of the laptop are determined by the presence of a wireless network adapter labeled Dell Wireless 1708. This adapter supports 802.11b/g/n standards (2.4 GHz band) and has an integrated Bluetooth 4.0 module.
Note that the top-end configuration of the Dell Inspiron 13 7000 series laptop can also install an Intel Dual Band Wireless-AC 7265 adapter with support for 802.11a/b/g/n/ac standards.
The audio subsystem of the Dell Inspiron 13 7347 laptop is based on the Realtek ALC255 HDA codec. The laptop itself has two speakers. In addition, there is a combined mini Jack audio jack (microphone, headphones).
It remains to add that the laptop is equipped with a built-in HD webcam (720p) located above the laptop screen, as well as a non-removable battery with a capacity of 43 Wh.
In addition, we note that according to the Dell website, Dell Inspiron 13 7000 series laptops can be equipped with various LCD screens. In our case, the laptop had an IPS touch screen with a resolution of 1366x768, but a touch screen with a resolution of 1920x1080 can also be installed.
Appearance and ergonomics of the case
First of all, we note that the Dell Inspiron 13 7347 laptop does not belong to the ultrabook category, although in many respects it meets the ultrabook specifications. Indeed, it is very thin (19.4 mm), lightweight (although there are no obvious weight restrictions in the ultrabook specification) and has a touch screen. Actually, in its concept, the Dell Inspiron 13 7347 is a classic ultrabook, but there is one small detail that prevents it from being classified in this category. The fact is that custom ultrabooks must be equipped with Intel wireless network adapters and must support Intel WiDi technology (this support is impossible without an Intel network adapter). However, the Dell Inspiron 13 7347 does not implement this.
However, the fact that the Dell Inspiron 13 7347 does not belong to the category of ultrabooks does not in any way detract from its advantages. Moreover, the very concept of ultrabooks has already played its role in the market and has now ceased to be relevant.
The body of this laptop is completely plastic. It has a silver metallic color, and the internal working surface is exactly the same as the external surface of the case.
Of course, the plastic case, painted silver, has its drawbacks. Scratches appear on such a case quite quickly (especially if you carry it in a briefcase with a metal zipper). But, on the other hand, fingerprints do not remain noticeable on the surface of the case.
In the center of the laptop lid is the traditional mirrored Dell logo. It should be noted that the laptop lid (actually, the screen) does not have sufficient rigidity and flexes greatly when you press it, causing characteristic spots to appear on the screen.
The system for attaching the laptop screen to the case consists of two hinges located at the bottom of the screen. This mounting system allows you to tilt the screen itself relative to the plane of the keyboard at an angle of 360°, turning it into tablet mode. Moreover, when the angle between the keyboard plane and the screen exceeds 180°, the keys and touchpad are automatically blocked.
Actually, this is the hybridity of this device. Naturally, the ability to open the screen to an angle of up to 360° also provides for two intermediate modes, which are called “console” and “presentation”. In general, everything is the same as in the Lenovo Yoga series convertible laptops.
The hinge has a fairly tight movement, which allows you to fix the screen in any position, but there is also quite a decent amount of screen play. Moreover, the presence of such a backlash greatly complicates touch input in the “laptop” and “console” modes. In the “presentation” mode, when the screen rests with one edge on the table and the hinges are located on top, there is naturally no play.
Note that the laptop's built-in position sensor works flawlessly and when changing from "laptop" mode to "console", "presentation" or "tablet" mode, the image on the screen rotates properly.
Since the laptop screen is touch-sensitive, the screen frame and the screen itself form a single plane and are covered with glass, which creates the illusion of a frameless screen design.
On the top of the frame there is a webcam, two microphones and a light sensor.
Naturally, if changes in screen brightness depending on external lighting are annoying, then the light sensor can be disabled in the power consumption scheme settings.
There is a traditional Windows button at the bottom center of the screen, which is convenient to use in tablet mode.
Since this laptop has a tablet mode, all the laptop control buttons are located on the side edges of the case.
On the left side of the case there are two USB 3.0 port connectors (one port with the function of charging mobile gadgets), a power connector, an HDMI connector, a combined mini jack audio connector (headphones, microphone) and a Kensington lock connector. In addition, there is a miniature grille that covers the built-in speaker.
On the right side of the laptop body there is a USB 2.0 port connector, a memory card slot, a power button and a rocker button for adjusting the volume. In addition, there is another miniature grille that covers the second built-in speaker, and there is also a niche for a passive stylus.
The stylus, by the way, is very convenient to use. In general, it is better to work with the touch screen of the Dell Inspiron 13 7347 laptop with a stylus. Firstly, the glossy screen coating will not be stained, and secondly, it is simply more convenient and productive.
On the front rounded end of the laptop body there is only one miniature battery charge indicator.
Note that the rounded front end of the body of the Dell Inspiron 13 7347 laptop is not only beautiful, but also very practical, since when working with the laptop, you will not rub your palms in the wrist area on the sharp edge.
At the rear end of the laptop case there is only a ventilation grille for the laptop cooling system.
Speaking about the design of the Dell Inspiron 13 7347 laptop case, one cannot fail to note the fact that it allows for easy disassembly. To do this, you need to remove the back panel of the case by unscrewing 10 screws.
By removing the bottom panel, you can access almost all components of the laptop: memory, wireless module, storage, cooling system, etc.
Input Devices
Keyboard
The Dell Inspiron 13 7347 laptop uses an island-style keyboard with increased distance between the keys. The keyboard has a two-stage backlight. The keys on the keyboard are black and their size is 15x15 mm. The gap between the keys is 3 mm. The base under the keyboard is slightly recessed relative to the working surface, as a result of which the surface of the keys themselves and the working surface are in the same plane.
The symbols on the keys (including Russian letters) are white and clearly visible.
It should be noted that the base under the keyboard is quite rigid and it practically does not bend when typing. The keys themselves are not very well spring-loaded and the press pressure is hard to feel. But the keys do not make any clicking sound. In principle, the keyboard is good, but could be better.
| Keyboard Specifications | |
| Number pad | No |
| Availability of backlight | There is |
| Feelings from printing | good |
| General impression | good |
Touchpad
The Dell Inspiron 13 7347 laptop uses a clickpad-type touchpad. The dimensions of the working area are 105×65 mm, which is quite enough for comfortable work.
The touch surface of the clickpad is slightly recessed. This touchpad supports multi-touch function.
There are no complaints about the operation of the touchpad. It has excellent sensitivity and no accidental triggering.
| Touchpad characteristics | |
| Touchpad size | 105×65 mm |
| Type | clickpad |
| Sensitivity | excellent |
| Random activations | No |
| General impression | excellent |
Sound path
As already noted, the audio subsystem of the Dell Inspiron 13 7347 laptop is based on the Realtek ALC255 HD codec, and the laptop itself has two built-in speakers.
According to subjective feelings, the acoustics in this laptop are quite mediocre. The maximum volume level may not be considered sufficient (I would like it to be higher), but at the maximum volume level there is no rattling observed. Of course, there is no bass here and when playing music tracks the sound is desaturated and has a slightly metallic tint. Therefore, it is better to use headphones to listen to music.
To evaluate the output audio path intended for connecting headphones or external speakers, we resorted to instrumental testing using an external Creative E-MU 0204 USB sound card and the RightMark Audio Analyzer 6.3.0 utility. Testing was carried out in stereo mode, 24-bit/44.1 kHz.
According to the test results, the audio path in the Dell Inspiron 13 7347 laptop received a “Very Good” rating.
The full report with testing results in the RMAA 6.3.0 program is presented on a separate page, followed by a short report.
| Frequency response unevenness (in the range 40 Hz - 15 kHz), dB | +0,01, −0,07 | Great |
| Noise level, dB (A) | −83,0 | Fine |
| Dynamic range, dB (A) | 83,1 | Fine |
| Harmonic distortion, % | 0,0026 | Great |
| Harmonic distortion + noise, dB(A) | −76,3 | Mediocre |
| Intermodulation distortion + noise, % | 0,039 | Fine |
| Interpenetration of channels, dB | −86,2 | Great |
| Intermodulation at 10 kHz, % | 0,013 | Very good |
| Overall rating | Very good | |
Screen
The Dell Inspiron 13 7347 laptop uses an IPS matrix with LED backlighting based on white LEDs. The diagonal screen size is 13.3 inches and the screen resolution is 1366x768. The screen has a glossy finish and is touch-sensitive.
First of all, we note that the change in screen brightness is carried out by changing the voltage level of the LED backlight, and not by pulse width modulation. That is, the LCD matrix in this laptop does not flicker at any brightness level.
According to measurements, the maximum screen brightness on a white background is 260 cd/m², and the minimum brightness on a white background is 15.8 cd/m². At maximum screen brightness, the gamma value is 1.85.
| Screen test results | |
| Maximum white brightness | 260 cd/m² |
| Minimum white brightness | 15.8 cd/m² |
| Gamma | 1,85 |
The LCD color gamut of the Dell Inspiron 13 7347 covers 58.2% sRGB and 40.6% Adobe RGB. Moreover, the color gamut is 58.9% of sRGB and 40.6% of Adobe RGB. In principle, this is a rather mediocre result for an IPS matrix.
Such a narrow color gamut is explained, among other things, by not very high-quality filters. Firstly, light filters strongly mix the components with each other. Thus, the spectrum of red color is heavily mixed with green, and the spectrum of green is heavily mixed with blue. Secondly, the red light filter highlights the maximum in the spectrum, which already belongs to the orange color (wavelength 590 nm, and not 620 nm, as usual), which negatively affects the color gamut of the screen.
The color temperature of the LCD screen of the Dell Inspiron 13 7347 laptop is very stable on the gray scale and is approximately 6200 K.
The stability of color temperature is due to the fact that the primary colors are well balanced across the entire gray scale.
As for color rendering accuracy (delta E), its value does not exceed 8, which is an acceptable result for this class of screens.
The viewing angles of the screen pleased me. They are really very wide and when looking at the image at an angle, the brightness decreases only slightly, but the color is practically not distorted.
In general, we can say that the screen of the Dell Inspiron 13 7347 laptop has its advantages, but there is also a disadvantage. The disadvantage is the narrow color gamut, but the advantages include wide viewing angles, stable color temperature and acceptable color accuracy.
Work under load and in idle mode
In idle mode, as it should be, the processor frequency in the laptop is 800 MHz (naturally, we are talking about a balanced power consumption scheme), that is, there are no complaints about Intel SpeedStep technology. The processor temperature in this mode is 43 °C.
When the processor is loaded with the Stress CPU test (AIDA64 Extreme Edition utility - a system stability test), which uses integer calculations, the processor frequency is 1.7 GHz (remember that Intel Turbo Boost mode is not supported for the Intel Core i3-4010U processor). The processor temperature in this boot mode increases to 48 ° C.
When the processor is loaded with the Stress FPU test, which uses floating point calculations and heats up the processor to a greater extent, the temperature of the processor cores increases to 59 ° C, and their frequency does not change and is 1.7 GHz.
In the mode of simultaneous loading of both the processor cores (Stress FPU) and the graphics core (Stress GPU), the temperature of the processor cores increases to 65 ° C. The processor core frequency in this mode jumps from 1.1 GHz to 1.7 GHz.
Memory subsystem and drive performance
According to the AIDA64 Cache & Memory Benchmark utility, the memory read speed is 11818 MB/s, and the write speed is 11933 MB/s. For DDR3-1600 memory (peak bandwidth 12800 MB/s) in single-channel operating mode, these are quite typical indicators.
Now let's look at the results of synthetic tests of the data storage subsystem.
The ATTO Disk Benchmark utility determines the maximum sequential write and read speed at approximately 100 MB/s, which is quite typical for 2.5-inch laptop HDDs.
The CrystalDiskMark utility gives almost the same results for maximum sequential read and write speeds.
In addition, we present the results of testing using the HD Tune Pro v5.50 utility. Actually, they only confirm what was said above.
Noise level
The cooling system of the Dell Inspiron 13 7347 laptop is a single cooler (radiator with a built-in fan), which is connected by a heat pipe to a heat removal plate covering the processor.
The Dell Inspiron 13 7347 laptop can be classified as average in terms of noise level.
According to our measurements, in idle mode the cooler fan does not rotate at all and the laptop does not make any noise.
When the processor and video card cores are under stress, the noise level emitted by the laptop is only 29.5 dBA. This is a very low noise level that blends in with the natural background level. And you can only hear a laptop in its stress loading mode in a very quiet room.
| Load scenario | Noise level |
| Idle mode | N/A |
| CPU stress | 29.5 dBA |
Battery life
We measured the tablet's battery life using our new method using the iXBT Battery Benchmark v.1.0 script. Let's remember that we measure battery life at screen brightness of 100 cd/m².
The results of offline testing are shown in the table.
| Load scenario | Working hours |
| Watch video | 6 hours 55 minutes |
| Working with text and viewing photos | 9 hours 33 minutes |
In principle, this is a very good result. That is, this laptop is quite enough for a full day of work without recharging.
Performance Research
To evaluate the performance of the Dell Inspiron 13 7347 laptop, we used our methodology for measuring laptop performance using the iXBT Notebook Benchmark v.1.0 and iXBT Game Benchmark v.1.0. Note that the laptop was tested while powered from the mains and with a fully charged battery.
The test results in the iXBT Notebook Benchmark v.1.0 are shown in the table. In addition, for clarity, we have also added test results for the HP Pavilion 13-a020nr x360 (K1Q28EA) laptop. We chose this laptop for comparison for the simple reason that the HP Pavilion 13-a020nr x360 (K1Q28EA) can be considered as a competing solution. This is also a hybrid 13-inch laptop with a screen that opens 360° with laptop, console, presentation and tablet modes. In addition, the Dell Inspiron 13 7347 and HP Pavilion 13-a020nr x360 (K1Q28EA) laptops have almost the same performance, although they are based on different platforms. Thus, the HP Pavilion 13-a020nr x360 (K1Q28EA) is based on the AMD A8-6410 (Beema) APU.

In short, the results are as follows. In terms of integrated performance, the Dell Inspiron 13 7347 laptop is inferior to our reference system based on the Intel Core i5-3317U processor by almost 40%. There are several reasons for this. Firstly, the Dell Inspiron 13 7347 laptop uses a rather weak Intel Core i3-4010U processor, which, of course, cannot compete with the Core i5-3317U processor. Secondly, the SSD installed in our reference system has significantly higher performance compared to the HDD installed in the Dell Inspiron 13 7347. Finally, thirdly, the Dell Inspiron 13 7347 laptop has only 4 GB of DDR3 memory installed -1600, which operates in single-channel mode, while the reference system has 8 GB of memory operating in dual-channel mode.
But if we compare the performance of the Dell Inspiron 13 7347 and HP Pavilion 13-a020nr x360 (K1Q28EA) laptops, it turns out that they are almost the same. More precisely, the Dell Inspiron 13 7347 based on the Intel Core i3-4010U is 3% faster in performance than the HP Pavilion 13-a020nr x360 (K1Q28EA), which is based on the AMD A8-6410 (Beema) APU.
In conclusion, let's look at the results of testing the Dell Inspiron 13 7347 laptop in games:
| Game test | Maximum quality | Minimum quality | ||
| Average FPS | Minimum FPS value | Average FPS | Minimum FPS value | |
| Aliens vs Predator | 5,9 | — | 19,3 | — |
| Grid 2 | 12,5 | 12,5 | 33,5 | 25,9 |
| Bioshock Infinite | 7,0 | 2,5 | 24,5 | 12,4 |
| World of Tanks | 17,1 | 5,4 | 36,3 | 9,4 |
| Metro:LL | 3,3 | 1,6 | 11,0 | 3,0 |
| Hitman: Absolution | 2,4 | 1,3 | 13,3 | 10,8 |
Let us remind you that in games testing was carried out at a screen resolution of 1366x768.
Actually, only one thing can be said here: this is absolutely not a gaming laptop.
conclusions
So let's summarize. Externally, the Dell Inspiron 13 7347 is a very stylish laptop. Thin, light, and even the screen opens 360°. In general, it looks very elegant. Plus, this laptop has a good keyboard, a great touchpad, has a very long battery life and is very quiet. Another advantage of this model is the fact that you can very easily increase the memory capacity and change the HDD drive yourself.
On the other hand, no upgrade in this case will make this laptop truly productive. In terms of performance, the Dell Inspiron 13 7347 with an Intel Core i3-4010U processor can be classified as an entry-level solution, that is, it can be used only for the most basic tasks (office applications, Internet communication, watching videos, etc.).
In addition, we note that although formally the Dell Inspiron 13 7347 belongs to the category of convertible laptops, it is still a laptop with an additional option. Its use in tablet mode is inconvenient due to the fact that it is heavy and bulky for a tablet. Touch input in laptop and console modes is inconvenient even when using a stylus, as the screen simply wobbles. So the main mode of use of the Dell Inspiron 13 7347 is precisely the laptop mode.
The screen in this laptop, as already noted, is not bad: good brightness, excellent viewing angles, stable color temperature. At the same time, the narrow color gamut does not allow us to recommend it for serious image work. If we talk about the sound path, then listening to music through headphones is not satisfactory, but the built-in speakers are quite mediocre.
And the last thing worth mentioning is the painted plastic body. It looks stylish, but in terms of scratch resistance it leaves much to be desired.
We will not write about the cost of the Dell Inspiron 13 7347 laptop. We will not make price comparisons with competing solutions. It’s just that now, it seems, no one understands at what price it should be sold. And the prices themselves change every day.
Testing and additional benefits
When developing this laptop, the creators of the Dell Inspiron 15 3000 series sought to make a truly convenient and versatile gadget. Therefore, the manufacturing company carried out a series of testing studies, during which this laptop was operated in the most unusual conditions and tested in the most unpredictable places.
As a result, he acquired the following advantages:
- Thermal Resistance – The Dell Inspiron 15 has been tested to withstand short periods of exposure to high temperatures. Testing conditions maintained temperatures at 65 degrees Celsius (149 degrees Fahrenheit). This property will come in handy if the owner of the laptop leaves it in a personal locker at the gym or in a locked car.
- Reliable hinge system – the hinge system is tested for strength and reliability. The model is tested using 20,000 closing and opening movements. Even after such a test, the hinges remain in excellent condition.
- Hotkey system - tests to ensure the ability to withstand multiple keystrokes. As a result, the laptop can be guaranteed to withstand about 10 million keystrokes, which fall on frequently used keys. The touchpad buttons account for approximately one million clicks.
- Reliable buttons – No matter how you use the media and power buttons, the buttons are guaranteed to be pressed for up to 40,000 times.
- Well-thought-out case - The Dell Inspiron 15 has protection for internal components, this allows the laptop to withstand even 25 thousand turns of the lid and base.
- Tight fit of the battery - the laptop battery, even after 30 removals and subsequent installation, will fit as tightly as when purchasing a new device.
Interfaces and communications
If the Dell Inspiron 7490 is approximately the same in area as the XPS 13 7390, and less in weight, then the thickness of the laptop being reviewed today is still greater, and for many this will be good news.
Because on the 11.6 mm (at the thickest point) ends of the flagship there was not enough space for full-size USB ports, but in the 18 mm Inspiron there is already enough space for them. Actually, here they are: two USB 3.1 Type-A interfaces on the right side of the laptop body. And a combined audio jack next to them.
On the left side there is HDMI, a card reader for microSD and Thunderbolt 3 (USB-C) with support for Power Delivery technology. It is from the last port that the Dell Inspiron 7490 receives energy - unification continues, proprietary charging is a thing of the past. By the way, there may also be a retractable tray for nanoSIM cards, but this is an optional thing, and we do not yet supply modifications of this laptop with an LTE modem on board to Russia.
Wireless connections are provided by the Intel AX201 adapter with support for MU-MIMO 2×2, Bluetooth 5.0 and, more importantly, Wi-Fi 6, which will become a standard in the very near future. We tested the connection speed on the same home wireless network with a speed of 500/500 Mbit/s and a Keenetic Ultra router as the previous computers tested for our blog on Habré. For the Inspiron 7490, the figures were 280 Mbit/s for download (the record specifically for this network is somewhere around 380) and 530 Mbit/s for upload. During the test, there were no problems with the stability of the connection and data transmission, either in this or in other networks.
Suggested Accessories
The owner of a laptop can please his device with the appropriate accessories.
As a supplement the following can be used:
- Portable Speaker - The stylish Dell AD211 Bluetooth speaker offers long-lasting performance and supports NFC and Bluetooth 4.0 technology.
- Dell Tek Backpack - Specially designed for 15-inch devices. It has a universal design and is made from lightweight and at the same time durable materials. Neutral colors suit any style. This backpack has many convenient pockets that can be used to organize and store all kinds of devices.
- External hard drive – can be used to optimize space on the internal hard drive of a laptop. In this way, the user can protect their files, movies and photos.
Model 3542 Features
The laptop manufacturer Dell is known to many today. An equally popular laptop in the series is the Dell Inspiron 15 3542. Its body is made of plastic, there are no metal parts. The lid has a matte surface covered with light perforations. The textured surface is not only beautiful, but can also hide minor scratches that occur during use.
The display is framed by a black frame with a small width. There is a webcam on top that can be used for shooting and video communication. Glossy inserts are placed in the side areas of the case. In the process of pressing the body, there are no backlashes or excess creep, and the surface does not sag.
Iron
The laptop received an Intel Core i5-6200U as a processor. This processor is characterized by good performance (for a laptop on which everyday tasks are performed), low power consumption and low temperature of the case under maximum load.
During testing, the processor demonstrated itself to be adequate hardware that can compete with laptops from other companies in terms of performance.
Some may object, because the RAM capacity is only 4 GB, but, nevertheless, the Dell Inspiron 13 5368 not only copes with standard tasks for a tablet, but also plays games like World of Tanks, for example. Of course, the graphics settings won’t be set to maximum, but that’s something. A kind of computer “Mom, I need it for studying” with nice Easter eggs.
As I already said, the case practically does not heat up at maximum loads. Of course, the cooling system starts to make noise, but this happens everywhere, even with laptops, and in this case the fans make noise only when running heavy games.
If we talk about sound, the Inspiron 13 5368 was not an audiophile discovery. The speakers are ordinary - good for movies and even music. Although the sound in the headphones is a level higher and better than the sound of the speakers, nevertheless, no noise or wheezing occurred in any of the cases.
Customer Reviews
The working panel of model 3542 is made of plastic and is scratch-resistant. This can be called an advantage, unlike fingerprints that remain everywhere. Fortunately, they can be easily removed using any cloth. Glossy sides are the most vulnerable zone in this sense. If you connect the flash drive carelessly, scratches occur. It's good that this is not on the working part.
I'm glad that you can download drivers for Dell Inspiron 15 Windows 7. The 8.1 operating system is not so convenient to use, so many buyers make a replacement.
In the 3000 model of the same series, users note excellent image clarity and ease of use. The battery performs well, but the charger cable is too short and creates inconvenience. The overall quality of this laptop can be said to be good.
In some cases, inconveniences arise with connectors that are placed very close to each other. Some users complain about problems running the latest generation of games, however, the technical specifications indicate that the laptop is not designed for the needs of modern gamers. In terms of power, the device does not disappoint. The overall design of the series is unremarkable.
If you need an improved design, then you should pay attention to the Dell Inspiron 15 5000 series. The 5547 model has a very stylish design, which can be called one of the best features of this device. Despite the budget nature of this laptop, its polished aluminum lid looks solid, which allows this model to be mistakenly classified as a fashion device.
