Dell Inspiron 15-5558 Notebook Review

Sascha Mölck (translated by Liala Stieglitz), 07/03/2015

Dark screen. Dell sends a 15.6-inch all-rounder into the fight for buyers' favor with its Inspiron 15-5558. The laptop pleases with an IPS screen that, however, has a much too low brightness. Dell could have been a bit less tightfisted with the GPU.

For the original German review, see here.

Dell's Inspiron 15-5558 is the newest scion of the Inspiron 15-5000 lineup and is a 15.6-inch all-rounder. The laptop only has something in common with its precursor in terms of processor. Both models are furnished with Broadwell processors. The 5558 comes with a new casing, and the AMD graphics core still installed in the precursor has now been replaced with a GPU from Nvidia.

Laptops like Acer's Aspire E5-571G, HP's Pavilion 15 and Toshiba's Satellite L50-B count to the Inspiron's rivals.

Case

The Inspiron's casing is no stranger to us. Dell also used it for the recently tested Vostro 15-3558. Differences are found in the color and surface finish. The casing is completely made of plastic. The lid's back and base unit's sides feature silver-color plastic, and the lid's back is structured. The display bezel and base unit's underside feature black plastic. The base unit's upper side has a dark-gray rubber finish. A maintenance cover is on the laptop's underside. The Inspiron's battery is easy to remove.

The laptop does not display any serious manufacturing flaws. The material only protrudes a bit on the lid's sides. As to stability, the base unit exhibits the usual shortcomings that we know from most laptops: The base unit can be dented lightly on the keyboard's left and right. However, it could be stiffer; it is too easy to warp for our taste. That is also true for the lid. Pressure on the lid's back leads to image distortions in some places. The hinges keep the lid firmly in position and rock slightly. Opening the lid with one hand is possible.

Connectivity

The diversity of interfaces will not impress anyone and can be described as standard fare. Of the three USB ports, only one supports the USB 3.0 standard. We expect more these days. Furthermore, Dell has only installed a Fast Ethernet port in the laptop. Gigabit Ethernet is standard nowadays.

Communication

Surprisingly, Dell has only furnished its Inspiron with a Fast Ethernet chip. We would expect a Gigabit Ethernet chip nowadays. After all, other manufacturers also manage to install such chips - even in the low-cost laptop sector. It looks better with the Wi-Fi module, which is an Intel Wi-Fi chip (3160). Positive: In addition to the Wi-Fi 802.11 a/b/g/n standard, it also supports the high-speed ac standard. Bluetooth 4.0 is also incorporated on the module. The connection to the Wi-Fi router was always stable. We did not ascertain any reduction in connection speed within a radius of 15 meters around the router.

Accessories

Only safety information and a quick-start poster are in the laptop's box.

Operating System

The operating system is Windows 8.1 (64-bit). A recovery DVD is not part of the included accessories. Users can replace Windows 8.1 with Windows 7 if preferred. Dell provides the necessary drivers.

Maintenance

The maintenance cover can be opened after releasing both fixture screws. The user can then access the hard drive, working memory banks, Wi-Fi module, and BIOS battery. Replacing the hard drive is throughout possible. 2.5-inch models with a height of 7 mm can be installed. The laptop features two working memory banks. Each bank is filled with a 4 GB module. The fan cannot be accessed this way. The casing would have to be opened for that.

Warranty

The laptop is shipped with a one-year warranty by standard when bought directly from Dell. Otherwise it comes with a two-year standard warranty. The warranty can be upgraded in both cases. A three-year on-site warranty, for example, costs 220 Euros (~$243).

Input Devices

Keyboard

The Inspiron features a chiclet keyboard that includes a number pad. Our review sample does not offer a backlit keyboard. The flat, lightly roughened keys have a short drop and clear pressure point. The keyboard yielded slightly while typing on it, but we did not find that distracting. The keyboard will not win any awards, but the buyer nevertheless gets a decent keyboard for home use.

Touchpad

The multitouch ClickPad in the Inspiron has a surface area of approximately 10.5 x 8 cm. The laptop's owner thus has a lot of room for using gestures. The single gestures can be turned on and off in the pad's configuration menu. The base unit's rubber-coated upper side is not continued on the ClickPad. The latter's surface is lightly roughened, but that does not prevent the fingers from gliding. The pad has a short drop and clear pressure point.

Display

The review sample that we were provided with had a matte screen with a native resolution of 1920x1080 pixels. The Inspiron is also available with an HD screen (1366x768 pixels). Both the contrast (1180:1) and black level (0.15 cd/m²) of the Full HD screen are very good. However, its brightness is disappointing. A rate of 175.7 cd/m² is no longer up-to-date. We expect a minimum rate of 250 cd/m² here. Curiously, the brightness increased by a good 30 cd/m² in battery mode.

The screen cannot reproduce either the sRGB or AdobeRGB color spaces. The coverage rates here are 61% (sRGB) and 39% (AdobeRGB). The screen's DeltaE 2000 shift in factory state is 8.52. A rate of less than 3 would be desirable. The screen does not exhibit a bluish tint. However, a light reddish tint is visible.

Dell furnishes the Inspiron with a viewing-angle stable IPS screen. Consequently, the screen remains legible from every position. Outdoor use is difficult to impossible due to the screen's low brightness. Its preferred application site will be shadowy surroundings.

Performance

Dell's Inspiron 15-5558 is a member of 15.6-inch all-round laptops. It has enough computing power for everyday use and allows playing computer games to a limited extent. Our review sample is available for approximately 700 Euros (~$773). Dell also has other configurations in its lineup - with and without a dedicated GPU. The currently lowest-priced device costs around 430 Euros (~$475).

Processor

A current mid-range CPU from Intel in the form of the Core i5-5200U (Broadwell) dual-core processor is inside the Inspiron. It is a frugal ULV processor with a TDP of 15 watts. The processor clocks at a base speed of 2.2 GHz, which can be boosted to 2.5 GHz (both cores) or 2.7 GHz (one core only) via Turbo. It can develop its full performance in both AC and battery modes. The tests we performed were always processed at full speed. Thanks to slightly higher speed and the improved Broadwell architecture, the Core i5-5200U scored better than its precursors of the Haswell generation (Core i5-4200UCore i5-4210U) in our benchmarks. The Broadwell processor could reap in an advantage of up to 10% here.

System Performance

The system ran smoothly and we did not encounter any problems. The PCMark benchmarks scores are good. A look at our comparison chart shows that laptops based on an AMD graphics core achieve considerably better results than the Inspiron in PCMark 8. We have observed this very often. The PCMark 8 benchmark particularly benefits from AMD GPUs. Installing a solid state drive could boost the Inspiron's system performance. Potential Inspiron buyers who are also considering an alternative laptop with a standard quad-core mobile processor should be aware that its higher performance will hardly have an impact in routine use. The quad-core processor can first utilize its higher performance in applications that benefit from high CPU power.

Graphics Card

We have tested most graphics cores from Nvidia's current GeForce 900M lineup. We could usually only ascertain a marginal performance plus of only a few percent over the corresponding precursor graphics core. The reason: The cores are based on the same architecture as their precursors and only clock at slightly higher speeds. This is a bit different with the GeForce 920M graphics core installed in the Inspiron. Nvidia uses a different architecture (Kepler) here than in the GeForce 820M core (Fermi). The 920M achieves a considerably better score than the 820 core in the 3DMark benchmarks due to its new architecture. We recorded an advantage of 20 to 30%. The Radeon R7 M270 graphics core in the Inspiron 15-1548 scores slightly better than the GeForce 920 GPU in the 3DMark benchmarks.

The GeForce core alongside Intel's integrated HD Graphics 5500 GPU forms a graphics-switching solution (Optimus). Intel's GPU is active in routine and battery mode. The GeForce core is utilized for performance-driven applications, such as computer games. The graphics cores are switched automatically. The user normally does not have to intervene, but it is always possible when required.

Gaming Performance

The Inspiron's hardware can smoothly render many games in the HD resolution using low to medium quality settings. Games with low hardware requirements allow more. It is difficult to achieve playable frame rates in some smash hits. Reducing the resolution/quality settings might be required here. However, The Witcher 3 and Batman: Arkham Knight do not produce any playable frame rates then, either.

While the Inspiron still managed a 20 to 30% advantage over GeForce 820M laptops in 3DMark, this lead is somewhat lower in gaming practice. An average of 10 to 20% higher frame rates is reached here. The Radeon R7 M270 graphics core in the Inspiron 15-5548 is defeated marginally.

Users who want more gaming power will have to take another laptop. It is, however, not necessary to invest more money. The Aspire E5-571G equipped with a GeForce 840M core is available for a price starting at 500 Euros (~$552, without Windows operating system).

Emissions

System Noise

The fan permanently spins at a low speed in idle, but it is not audible. The hard drive drowns out its noise. Replacing the hard drive with a solid state drive would reduce the noise somewhat. The fan speeds up a bit too much under load in view of the mid-range CPU and entry-level GPU installed in the laptop. The cooling requirement should thus be within limits. We measured a noise level of roughly 45/46 dB - we have seen better in contenders, such as Acer's Aspire E5-571G.

Temperature

The Inspiron in the stress test
The Inspiron in the stress test

The graphics core processed our stress test (Prime95 and Furmark run for at least one hour) at 954 MHz in both AC and battery modes. The processor clocked at 1.8 to 1.9 GHz (battery mode) and 2.2 to 2.5 GHz (AC mode). The Inspiron's temperatures only increased very slightly. The temperatures remained below 40 °C on all measuring points. The fast-spinning fan is noticed here.

Speakers

The stereo speakers have been positioned on the underside of the casing's front edge. Their sound is satisfactory in total. They exhibit the common shortcomings, such as the lack of bass and a slight tendency to be tinny. However, it is still possible to listen to them for a longer time without an earache.

Energy Management

Power Consumption

The Inspiron does not have an excessively high energy requirement throughout the entire load range. The idle power consumption remained below 10 watts, which is how it should be. The requirement increased up to 36.3 watts during the stress test. This rate would be higher if the CPU utilized its Turbo in the stress test (it is naturally utilized in routine use). The power supply with a nominal capacity of 65 watts is not a restricting factor. A power consumption of roughly 33 watts would be realistic for gaming routine.

The power supply has a nominal capacity of 65 watts.

Battery Runtime

The Inspiron manages an idle runtime of 11:06 hours. Acer's Aspire E5-571G (13:15 h) lasts longer. Idle mode is ascertained with Battery Eater's Reader's test using minimum screen brightness, enabled energy-saving mode, and disabled radio modules. The Inspiron shut down after 1:43 hours of load. The Aspire (2:52 h) achieves a considerably longer time. The load runtime is determined using Battery Eater's Classic test with maximum screen brightness, high-performance profile, and enabled wireless modules.

Dell's laptop stopped our real-life Wi-Fi test after 5:37 hours. Again, the Aspire (6:52 h) exhibits more stamina. This test simulates the load produced when opening websites. The "Balanced" profile is used, and the screen's brightness is approximately 150 cd/m². We check the video playback time by running the short movie Big Buck Bunny (H.264 encoding, 1920x1080 pixels) in a loop. The wireless modules are off and the screen's brightness is set to roughly 150 cd/m². The Inspiron lasted for 5:15 hours. The Aspire (7:04 h) has the lead once more.

It is clear that the Inspiron cannot compete with the Aspire's runtimes. Acer's laptop has a higher capacity battery (Dell: 40 Wh, Acer: 56 Wh).

Verdict

In review: Dell Inspiron 15-5558. Test model courtesy of Dell Germany.
In review: Dell Inspiron 15-5558. Test model courtesy of Dell Germany.

Dell has a 15.6-inch all-round device in its lineup with the Inspiron 15-5558. The installed processor offers enough power for routine use. The GeForce graphics core allows gaming at least to a certain degree. However, we would have expected a stronger GPU, such as the GeForce 930M or 940M at a retail price of approximately 700 Euros (~$773). The laptop usually operates quietly and does not heat up excessively. Furthermore, there is plenty of storage capacity. The screen makes a mixed impression: Although the installed viewing-angle stable, Full HD, IPS screen can offer high contrast, its brightness is only very low at the same time.

Dell might just have a decent all-rounder in its lineup with the Inspiron. However, the company has made some unnecessary mistakes with the laptop (screen brightness, choice of GPU), which prevent a better rating. Our present model is an average all-rounder at a slightly too high price.
