The Hybrid Drive dramatically improves performance. It's 2 drives, a super fast 8GB SSD Drive and a 500GB SATA Drive. Boot time is about 8 seconds. Return from Hibernation even faster

The Inspiron 15-7537 excels with almost all features that are expected from a modern, high-end laptop: A swift Intel Core i5-4200U from the Haswell generation supplies appealing performance, while a plentiful 6 GB of RAM and a Hybrid 8GB SSD - 500GB SATA Drive cover storage needs. Even gaming fans are satisfied and can enjoy up to date titles on a 15.6-inch Full HD touchscreen owing to the dedicated Nvidia GeForce GT 750M.

In view of this hardware power, it is not surprising that the purchase price does not fit into tight budgets. Approximately 799 Euros (~$1078) plus shipping is currently demanded for the described configuration. On the whole, the new series competes with other premium multimedia laptops, such as the Samsung ATIV Book 8 or Acer Aspire V7-582PG.

Case - Solid aluminum casing

The Inspiron's solid aluminum chassis makes it look bulkier than it actually is. Except for the base plate, almost the entire laptop is made of this light metal. Its matte surface supplies a high-end feel. The screen's black frame adds the matching contrast to the mostly silver color. The screen itself is covered with particularly resistant Corning Gorilla Glassthat protects it from scratches.

Although the casing's height is just a bit over 2.2 centimeters, the laptop's weight of approx. 2.6 kilograms is comparatively high. The focus was obviously placed onstability and quality rather than portability. Both the base unit and the screen defy even stronger force without visible distortions or annoying creaking noises. The stiffness is also at a very high standard.

The long display hinge is almost pulled too tight and the user will have to use both hands to open it. Dell promises that the hinge will work impeccably even after closing the display 20000 times - we naturally cannot verify this in the course of the test, but the entire laptop makes a subjectively extremely rigid and durable impression. Alongside the virtually immaculate build quality, even in details, the Inspiron outshines some contenders.

Connectivity

The user is given many options for connecting additional peripherals owing to four USB ports that all correspond to the current USB 3.0 standard. Unfortunately, the laptop does not have any other noteworthy highlights apart from that. Almost all contenders offer a card reader (SD/MMC/MS), a headset jack and/or Gbit LAN. We would have, for example, appreciated a (mini-) DisplayPort since the HDMI out is only suitable for very high-definition monitors to a certain degree. It would also have been great if Dell had placed frequently used interfaces a bit further front on the casing.

Communication

Contrary to the information on Dell's online shop, where an 802.11 ac capable Wi-Fi adapter is sometimes specified, our review sample "only" sports an Intel Wireless-N 7260 module. This model only supports the IEEE 802.11 a/b/g/n standards besides Bluetooth 4.0. However, it transmits in both the 2.4 and 5 GHz networks owing to dual band support. This enables gross data rates of up to 300 Mbit/s (dual-stream, 2x2) providing a suitable router is available.

The solid metal casing seems to have a negative impact on the connection quality and range. The transmission rates slightly lag behind other laptops in medium and larger distances. Users who rely on good Wi-Fi reception might need an additional range extender.

The 1.0 megapixel webcam is also a standard. Like most contenders, the image quality is at most suitable for communication purposes. Pictures and videos are OK. The array microphone's very loud and clear transmission does a better job.

Accessories

The manufacturer does not add extras and includes a matching 90 watt power supply for the laptop. The preinstalled Windows 8 operating system (64-bit) is just as lean. Apart from some superfluous adware - we have seen much worse things in other devices - and the compulsory virus scanner (trial version of McAfee), the system is almost bare.

Maintenance

After removing four screws, the device's underside can be opened to a large extent. Both memory banks and the 2.5-inch slot are unfo filled ex-factory, just like the sole mini-PCIe slot., Upgrading is possible by removing the existing components.

The manufacturer has to be praised for the fact that the heat sink and fan can be cleaned without disassembling the laptop even more. This should be done regularly to prevent increasing hardware temperatures and thus a higher risk of failure depending on the surroundings.

Warranty

As typical for Dell, the Inspiron 15 comes with a short 12 month warranty (collect and return service). Of course, the service package can be upgraded but the demanded prices are quite steep - this should also be considered when comparing with the competition. A dizzying 129 Euros (~$174) is charged for an upgrade to two years on-site service and more for three or four years (189/249 Euros, ~$255/$336).

Input Devices

Keyboard

The silver-gray chiclet keyboard resembles that of other models from the Inspiron series but is not completely identical. The layout was compressed a bit because of the fairly wide lateral frame and some keys, like Enter, are small. However, the letter keys are still 15 x 15 millimeters in size and the convenient number pad is also installed. Another handy extra is the two-level backlightthat submerges the keyboard in a gentle white light.

The typing feel convinced us to an extent. The agreeably firm stroke has a slight recoiling and short drop. It needs a bit of time to get used to this peculiarity. The noise development is pleasantly restrained. Activity is only noticed by a quiet clacking noise even when typing fast.

Touchpad

Like many other manufacturers, Dell more and more uses touchpads in the so-called ClickPad design. It is enough to press the corresponding side of the here generous 10.5 x 8 centimeter input surface to trigger a mouse click. The short and crisp pressure point compensates for the omitted dedicated keys.

The pad's lightly textured surface provides the finger with a certain resistance which enables a better feedback. Other advantages are the support of various multi-touch gestures with up to 4 fingers and the extremely accurate implementation of all input commands.

Touchscreen

Although the Inspiron 15 is not an ultrabook and therefore does not imperatively need a touchscreen, it belongs to the standard configuration of all models offered in Germany. The accuracy and responsiveness are excellent and facilitate using the new Windows 8 user interface. Some users would likely appreciate a matte screen without touch function, which would also reduce the device's weight and production costs.

Display

Depending on the Inspiron model, the 15.6-inch screen has a resolution of either 1366x768 (WXGA) or 1920x1080 pixels (Full HD). The latter screen is installed in our review sample and reaches a pixel density of 141 dpi. Even if some laptop screens are now quickly closing in on 300 dpi, we deem this resolution to be a sensible compromise between price, screen size and focus. Also, it is more likely that interpolation is unnecessary in games.

The screen's 267 cd/m² we ascertained is a good rate. The brightness, which is also consistently maintained in battery mode, is distributed quite homogeneously over the entire screen. The slight decrease at the upper edge is virtually imperceptible to the human eye.

The strong backlight is useful outdoors but this advantage is partly reversed due to the screen's glossy surface. Intense reflections, particularly in direct sunlight, are a problem and again make us want a matte screen. However, this is equally true for the competition from Acer that relies on a glare-type touchscreen.

As appropriate for a high-quality IPS screen, the content largely remains true and well-legible even in extremely slanted viewing angles. However, the rather intense brightness decrease as soon as an angle of approximately 30 to 40 degrees is surpassed is striking. Nevertheless, TN-based screens like many manufacturers still install even in higher price ranges do a much worse job here.

Performance

3.0 GHz maximum Turbo speed
3.0 GHz maximum Turbo speed

Gone are the times when energy-efficient ULV processors were exclusively reserved for compact ultrabooks or subnotebooks. Full-blown multimedia machines now also use these CPUs more frequently because they allow a particularly thin build. Another reason is the rapid performance increase: The Core i5-4200U has two cores with a clock rate of 1.8 to 3.0 GHz, which ensures an outstanding performance despite its low TDP of 15 watts. Of course, the Haswell CPU also supports Hyper Threading and the new AVX2 extension; more details about this and other features can be found in our database.

No matter whether entry-level or top model, all configurations of the new Inspiron 15 not only feature the processor-integrated HD Graphics 4400 but also sport a dedicated GeForce GT 750M. This accelerator is located in the upper midfield and should easily cope with most current games - but more about that later. Nvidia's Optimus technology selects the most suitable GPU for the situation completely automatically so that the energy-hungry GeForce card is only enabled in demanding 3D applications.

The manufacturer is very generous in terms of memory and treats the laptop to an awesome 6 GB of RAM alongside a 8 GB SSD. .

Right after starting a benchmark, the Core i5-4200U behaved as expected at first and easily reached its maximum Turbo of 2.7 GHz in multi-threading and 3.0 GHz in single-threading depending on the load. However, this changed after about 30 seconds of load. We observed aclock rate drop to 1.8 up to 1.9 GHz although the temperatures were not critical (single-thread test: 2.5 to 2.6 GHz). This naturally affects the score negatively. The Turbo was only maxed out partially in other benchmarks as well.

The reason for this occurs in both AC and battery mode will presumably be found in the BIOS. According to Intel's Extreme Tuning Utility, the CPU's TDP has apparently been incorrectly set to 10.5 watts, which would be a logical explanation for this behavior. The clock rate and performance climbed to roughly the expected level after we manually set the correct 15 watts (Cinebench R11.5: 1.32/2.71 points).

Storage Devices

AS SSD benchmark
AS SSD benchmark

After the in-depth review of the more or less identical sister model, we do not have to say much about the performance. No matter whether sequential transfer rates or the speed in accessing small 4K files, the storage device is at the very top of current flash memories in all subdivisions.

System Performance

Despite the CPU's limited Turbo, the Inspiron 15 stands out with an excellent system performance. Virtually the entire competition is outclassed with 5454 points in PCMark 7. However, this comparison is not really fair because only Dell's laptop features a full-fledged SSD.

This is often worth more than a swift quad-core processor in routine use. Many start and loading processes are limited by the storage device's speed, which is much lower with a conventional hard drive. Of course, there are applications that benefit from a stronger processor. A ULV CPU will not satisfy users who edit large images or videos on a regular basis and they should preferably look atSamsung's ATIV Book 8 or Asus' N550JV.

Graphics Card

Nvidia's GeForce GT 750M is based on the same GK107 chip as the GT 650M, which has been available for a while, but is clocked a bit higher. In this case, the core frequency is 940 to 1058 MHz (Turbo), while the large 2 GB memory connected to a 128-bit interface runs with 1000 MHz (effectively: 4000 MHz). Dell has earned special praise for deciding to install the faster GDDR5 version of the GT 750M. With 64 GB/s, it has more than twice the memory bandwidth of the DDR3 model, which primarily speeds up the performance in high resolutions and quality settings.

Depending on the benchmark, the GeForce GT 750M even outperforms the GTX 660M and comes very close to the Radeon HD 8870M. The requirements for a strong gaming performance should thus be fulfilled.

Gaming Performance

Saints Row IV
Saints Row IV

We put it to the test: Apart from a slight lapse in low settings - the processor occasionally slows things down here - the Inspiron is absolutely top notch. Again, the GT 750M is within reach of the Radeon HD 8870M, although it fluctuates massively from game to game, and clearly surpasses its DDR3 version.

Nevertheless, the performance is usually not enough to render the screen's native resolution smoothly, at least not in high details. High settings and 1366x768 pixels, which are interpolated quite decently, are possible without limitations in most cases. Users who want a laptop with considerably higher gaming power will have to take a bulky gaming machine with a GeForce GTX 765M or higher.

Emissions

System Noise

The user will have to listen closely to hear the Inspiron's fan that spins with at most 32.4 dB(A) in idle. The cooling sometimes even stops completely, which results in an absolutely silent total system alongside the SSD hard drive. The laptop remains very quiet in many routine applications, such as office, browsing, or videos.

In unrealistic extreme situations simulating heavy load, the noise level increases up to 42.5 dB(A). The laptop produces an audible but not distracting noise in 3D games and comparably demanding software, which seems acceptable in view of the hardware's power. However, we have to deduct points for the power supply because it buzzes quietly in some cases.

Temperature

Stress test
Stress test

Despite the fan's restrained behavior, the casing only heats up insignificantly in idle. We measured temperatures of around 24 to 26 °C on both the upper and underside. This temperature even feels much cooler due to the aluminum's high thermal conductivity. Consequently, the laptop can be used on the thighs without restrictions.

hot spot of over 50 °C is generated above the keyboard when both the processor and graphics card are loaded over a longer time. However, this will not be distracting for the user since most parts of the chassis, in particular the wrist rest, remain very cool.

The temperatures inside the casing are also within an acceptable range. The processor and graphics unit recorded uncritical rates between 75 and 80 °C after our one-hour stress test. Thus, there are enough cooling reserves even for hot summer days. However, unlike the GPU that can maintain a high clock rate of 967 MHz, the processor nosedives to almost 1.5 GHz - this is another indication that the CPU's frequency control has been set a bit too defensively.

Speakers

Dell installs two, downward-firing stereo speakers that strongly emphasize the laptop's multimedia ambitions with a good quality. Clear trebles, an incredibly powerful bass range for a laptop, and the high maximum volume make external speakers unnecessary in many cases. Users who want to connect a headphone or an additional amplifier anyway, can use either the analog, 3.5 millimeter jack or the digital HDMI out.

Energy Management

Power Consumption

The Haswell ULV platform excels with record-breaking low consumption rates owing to the integration of the chipset and a few new power-saving features. Our review sample consumes a minimum of only 5.4 to 9.9 watts when idling, which makes the Inspiron 15 one of the most energy-efficient laptops of its category.

As expected, the power consumption increases considerably during load with 59.6 to 66.1 watts, which is still almost 10 watts less than the identically equipped Acer Aspire V7. This is likely due to the somewhat lower CPU clock of Dell's laptop, but both models are nevertheless admirably efficient. The included 90 watt power supply has more than enough reserves.

Battery Runtime

The 58 Wh battery inside the casing ensures impressive battery runtimes owing to the low power consumption. The Inspiron lasted for a remarkable 12 hours and 7 minutes without an outlet in ideal conditions, like in Battery Eater's Reader's test using energy-saving mode, minimum brightness, and Wi-Fi off.

The runtime is much shorter with 6 hours and 32 minutes in our practical Wi-Fi test using energy-saving mode and approx. 150 cd/m². However, this is a top rate compared with the contenders; evenSamsung's ATIV Book 8 with a high-capacity 91 Wh battery cannot defeat that.

Since Dell does not artificially restrain either the CPU or GPU in battery mode, the user can venture with gaming on the go. However, the power supply should always be at hand because the battery has to be recharged after just 1 hour and 7 minutes. We ascertained this using Battery Eater's Classic test in high-performance mode, maximum brightness, and Wi-Fi on.

Verdict

Dell Inspiron 15-7537
Dell Inspiron 15-7537

A max purchase price of almost 1200 Euros (~$1619) is steep even for a luxuriously configured multimedia laptop. The customers rightly expect the highest degree of perfection even in detail - a demand that not every device can meet.

Dell has introduced a largely convincing product with the Inspiron 15-7537. The laptop reaps in bonus points particularly for its high-quality casing, the high-performance in both applications and games, and thebright, viewing angle stable IPS touchscreen. Nevertheless, an optionally available matte screen would be welcome so that the outstanding battery runtimes could also be fully enjoyed outdoors.

We would have appreciated a bit more fine-tuning in a few other things. For example, we missed support for the latest 802.11 ac Wi-Fi standard and a slightly higher wireless-transmission range. Theshort warranty period that can be upgraded for a relatively high price barely seems justified in view of the high base price.

None of the listed shortcomings are really severe - and the competition also struggles with the one or other drawback. Therefore, we would like to refer to our reviews of Samsung's ATIV Book 8Acer's Aspire V7-582PG and Asus' VivoBook S551LB to perhaps help decide, and which might be an alternative.
