Lenovo ThinkPad S5 Yoga 15 20DQ0038GE Convertible Review

Sebastian Jentsch (translated by Liala Stieglitz), 04/13/2015

Yoga goes standard. Will the Yoga concept be successful in a standard 15-inch work device? Can the Yoga reflect the classic virtues and bring new flexibility in equal measure? Disappointment is not far.

In review: Lenovo ThinkPad S5 Yoga 15 Modell 20DQ0038GE
In review: Lenovo ThinkPad S5 Yoga 15 Modell 20DQ0038GE

For the original German review, see here.

Thanks to its four modes of use, Lenovo describes its new Yoga 15 as versatile. Being a ThinkPad, it, its Yoga 12, and 14 sisters envision a rethinking. Business today - at least according to the manufacturer - should no longer be a straight-lined clamshell laptop, but a convertible that can be used in different modes just like the consumer devices. Whether the business world is prepared for such a turnaround will ultimately be seen in the sales figures. We are testing the standard model ThinkPad Yoga 15, appropriately configured with a Core i7-5500UGeForce 840M and a 256 GB SSD. The manufacturer has included an IPS screen with 1920x1080 pixels. However, far more than just a few showy specs are expected from a ThinkPad. Find out in the course of this test whether this enthusiasm lasts.

There are only a few rivals in the form of 15-inch convertibles. HP's Envy 15-u200ng x360 (700 Euro; ~$738) and Asus' Transformer Book Flip TP500LN (1000 Euro; ~$1054) both feature similar 360 degree hinges. However, they come from the consumer world, which involves a lower price and in some respects, inferior qualities.

Case

Road-tested quality has always been important in Lenovo's ThinkPads. Even the cheap Edge models offered a consistent measure of solid build. Unfortunately, the review sample falls short in this respect. The base can be warped extremely and sometimes produces cracking noises. When handling the device, the base unit seems too yielding and is not twist-resistant. Therefore, we do not quite understand the manufacturer's statements like "The ThinkPad Yoga 15's durable magnesium-alloy frame [...] can handle tough treatment from even the hardiest professional."

The two solid-looking hinges are not made of metal, but of a silver plastic cover and a small metal hinge hidden underneath it. The hinges are mounted on the outer sides of the base. In our opinion, although the construction is firm enough, it does not give the impression that it will keep the lid stable over many years. Walking around with the Yoga 15 in laptop mode was enough for the display to gradually tilt back and forth just from its own weight.

The lid with the touchscreen has to accept the same criticism. We think it is much too yielding for the purpose of a 360-degree convertible. Positive: No pressure marks are passed on to the screen during normal use, i.e. moderate, careful pressure. A sturdy rubber lip lines the screen, and closes flush with the base.

Lenovo has installed a retractable keyboard (Lift 'n' Lock) for the tablet mode. Like in the Yoga 3 or the ThinkPad Yoga 12, the keys are fixed, but the surrounding plastic grid lifts up to level with the keys when the display is completely folded over. The keys are then locked and can no longer be pressed. This is handy because the new "underside" of the tablet becomes relatively homogeneous.

The wrist rest yields slightly under pressure, and does not feature the highest strength.

Connectivity

The configuration of a 256 GB SSD, 8 GB of RAM (single-channel), three USB ports, and an HDMI port as well as a Full HD touchscreen is appropriate, but not abundant. The SIM-card slot on the review sample's left is without function, and Lenovo presently does not offer a model with an LTE modem. There are no security features, such as a fingerprint reader, TPM or SmartCard reader - aspects that are quite important for business customers.

Communication

Intel's Wireless-AC 7260 chip takes care of wireless connections; however, there is  no classic RJ45 port. The signal strength was slightly above average in the author's personal setup. The signal remained stable with 1 to 2 bars at the 45 meter (~148  ft) mark outside the building, and notebookcheck.com still opened at an acceptable speed. Four bars were displayed at a distance of 15 meters (~50 ft) to the router. These are indicators of decent but not extraordinary reception strength of the Wi-Fi antennas.

Security

The Kensington Lock on the left is the only evidence of security on the exterior. The UEFI BIOS provides the user with some options. For example, it is possible to activate/deactivate the TrackPoint or TrackPad separately here. Even the non-removable battery can be disabled for permanent stationary use. The user can create passwords for both general access (supervisor) and the hard drive.

Accessories

Apart from the power supply, the Yoga 15 does not come with any noteworthy accessories.

Maintenance

The topic of maintenance is rather insignificant in the Yoga 15. The underside is made of one piece; there is no maintenance cover, and the battery is non-removable - at least not for nonprofessionals.

Warranty

The manufacturer includes a 24-month warranty on the Yoga 15.

A webcam is found on the front. Not  only does it have a meager resolution of 720p, but it also shoots pale, blurry pictures even in daylight conditions. Unsuitable for a convertible in this price range.

Input Devices

Keyboard

LLenovo has equipped the ThinkPad Yoga 15 with a full-blown keyboard that utilizes the casing's entire width with large gaps. It is a standard chiclet model with conical keys and wide spacing. There are plenty of special keys, for example for the browser, calculator or switching screens. The F1 - F12 keys are mapped as function keys under the second assignment. The full-sized number pad has marginally smaller keys than the keyboard. The latter features a two-level backlight, but is not splash-water proof like the T-series ThinkPads. It is not a mechanical keyboard, but rather a Rubber Dome with a scissor switch (double-hinge) that ensures an impeccable key guidance (drop/travel).

The keys' surface is very sleek, the pressure point is crisp, and the stroke is firm yet not hard, but hollow in some places. The surface yields slightly under high pressure in the middle and on the right. Typing is enjoyable owing to the crisp pressure point and the subdued clicking noise. However, it does not match the perfection of a T series keyboard.

Touchpad

Once again, Lenovo relies on real keys for the mouse replacement - at least for the TrackPoint that is found between the "G", "H" and "B" keys. The TrackPad itself can be either combined with the keys above it or its lower corners are used for triggering a right or left mouse click. The ClickPad has a medium drop, a clear and responsive pressure point, and a firm stroke. The noise is rather loud and could quickly become distracting in noise-sensitive environments. Unfortunately, the pointer's keys are very smooth-running and might occasionally be triggered accidentally.

Touchscreen

The capacitive touchscreen functions accurately with up to ten fingers at the same time. However, we find the hinges' resistance too weak; the finger pushes the display back much too quickly when touching it. This is probably due to the 15-inch form factor. The tester did not notice this drawback in the ThinkPad Yoga 14.

Display

The LG-Phillips screen has a resolution of 1920x1080 pixels. An anti-glare film makes it relatively unsusceptible to greasy fingers and streaks. Lenovo speaks of a "scratch and smudge-resistant Dragon Trail Display". Pressure on the screen does not lead to clouding; we cannot say anything about the durability of the anti-glare film.

* ... smaller is better

It is an AH IPS a-Si TFT LCD screen that achieves a good contrast of 628:1 owing to a low black level of 0.5 cd/m². The user will agreeably notice this: Outlines stand out clearly, and colors are crisp and bright.

Our X-Rite i1Pro 2 measures a maximum brightness of 314 CD/m² in the center; the average is lower at 280 cd/m² due to the uneven illumination. Typically, laptops have an illumination of 80 to 85%, especially with this relatively high brightness. The ThinkPad is exactly within this range.

CalMAN determined a visible shift toward the warm colors in the sRGB color reproduction. It is a clear bluish cast that leads to a DeltaE 2000 of just below 6. This cast is also very evident in the grayscale levels. This is not distracting in practice, but it excludes professional image and graphic editors or they will want a calibrated external monitor. We could not measure the sRGB color space coverage due to the recurrent crashing of the i1 Profiler, and thus we could not recheck the reddish cast after creating a profile.

The screen's brightness in battery mode is maintained, but only when the ambient light sensor is disabled. Our screenshots were taken in sunlight. Depending on the viewing angle,  reflections still occur.

IPS screens have good to very good viewing angles, which is also the case in the ThinkPad Yoga. No matter from which angle we looked at the screen, colors never inverted.

Performance

Lenovo provides its ThinkPad Yoga 15 with two processor options: a Core i7-5500U or i5-5200U. The i7 model comes with either a 512 or 256 GB SSD and the i5 version comes exclusively with 256 GB. The options in the German market are limited. However, it is still a powerful package; the GeForce 840M is installed from the outset. Apparently, the manufacturer is not interested in low-cost configurations for the Yoga 15.

Processor

The Yoga 15 is powered by the Core i7-5500U dual-core processor (Broadwell). The CPU clocks with a base speed of 2.4 GHz, which can be boosted to 2.9 GHz (two cores) or 3 GHz (one core) via Turbo. The Turbo is extensively utilized. The CPU tests of the Cinebench benchmark were processed with 2.4 to 2.9 GHz (multithread) and 2.9 to 3 GHz (single-thread). This was the case in both AC and battery mode.

The higher speeds, combined with the improved Broadwell architecture give the Core i7-5500U a performance edge of approximately 20% over the i5-4210U or 10% over the i7-4500U. The optional i5-5200U  calculates only 7 to 12% slower; the buyer can readily choose the i5 when it is significantly cheaper.

Storage Device

The Samsung SSD is equally impressive in both writing and reading large and small blocks. Almost every modern SSD can easily manage 500 MB/s in sequential read and write. The 4K read/write tests are more critical; the results are more diverging although not to a great extent. In short: Lenovo has installed an efficient SSD model. The same SSD model is found in the ThinkPad T450 and the EliteBook 840 G2, and thus their scores are almost identical. Thanks to the 840M, the performance increase is 30 to 40% above a single HD 5500. However, this difference can be even greater in games, but this depends highly on the drivers. We ascertained a performance increase of 66% over the HD 5500 in “BioShock Infinite”.

Graphics Card

The ThinkPad Yoga 15 features a graphics switching solution. It is composed of Intel's HD Graphics 5500 graphics core and Nvidia's GeForce 840M GPU. The GeForce chip takes care of performance-hungry applications, and Intel's GPU is enabled in routine and battery mode. Switching between both cores is automatic, but the user can manually assign the preferred GPU when required. The GeForce core comes from the entry-level performance category. It supports DirectX 11 and clocks with a base speed of 1029 MHz. The speed can be increased to 1124 MHz via Turbo.

The 3DMark benchmark results show a clear dissociation to devices without a dedicated GPU. The Transformer Book Flip TP500LN also includes an 840M, but it is inferior in the 3DMarks due to its weaker processor.

System Noise

Noise? Users, who simply leave the Yoga 15 idling on the desk, will hardly hear anything from it. The fans are disabled when it is not loaded. This will change significantly under load when the noise level climbs to between 36 and 40 dB(A). This was the case, for example, in our stress test via Prime95 and FurMark.

Temperature

The surfaces remain cool, especially while idling. This is not surprising because the power consumption under Broadwell is at its lowest here. The base unit's upper side does not even reach 28 degrees Celsius (~82 °F). 

The picture changes under load, although it is mainly one hot spot that heats up to 46 degrees (~115 °F). This is not a critical temperature. The Cinebench R15 single calculated with 2.9 to 3.0 GHz, and the multi-test was slightly slower with 2.4 to 2.9 GHz. Thus, the Turbo is utilized perfectly, even in battery mode.

Speakers

The sound from the two speakers completely lack low pitches and bass. However, the trebles and the almost accurate volume are impressive. LatencyMon did not record any significant delays even after a quarter of an hour, and thus the Yoga 15 is suitable for use as a video/audio editing desktop (balanced drivers).

The microphone recording was more than decent. The tester's voice was recorded clearly and impeccably despite a distance of 0.5 to 2 meters (~1.6 to 6.5 ft) with his back turned to the laptop and walking across the room. The microphone is a very good basis for Skype chats.

Energy Management

Power Consumption

The Broadwell platform's power consumption is higher than in the comparison devices. This is firstly due to the dedicated graphics card, and secondly the bright touchscreen. The Yoga 15 consumes five to eight watts when not in use, while idling.

Battery Runtime

The battery life was a nice surprise. The ThinkPad Yoga 15 ran for 18 hours while idling (Wi-Fi off, minimum brightness). There are no secondary batteries or such like available, since the installed battery cannot be replaced.

However, the idle runtime is rather useless for the user. Our Wi-Fi test is more significant, which stopped after 414 minutes. That equals to almost seven hours. With the exception of HP's EliteBook 840 G1, the rivals cannot match this.

ThinkPad Yoga 15 - does Lenovo set the standard for rethinking in the business world? We believe that rethinking is not at all decisive. After all, the customer gets a conventional laptop that can be used like every other ThinkPad without a 360 degree hinge in mode one (laptop). The other modes of use increase the productivity of the Yoga 15 in some cases. Leaving other modes aside, anyone using the device exclusively as a laptop will get decent input devices and stable viewing angles.

But are we really satisfied? No, because the 15-inch device is maintenance-unfriendly (non-removable battery), and has only a few interfaces/security features. The Yoga 15 does not differ from a basic consumer laptop that is  not so expensive. It does not make a good impression when the heavy display warps the chassis when picking it up at one corner of the wrist rest. The chassis should be much stronger and harder, particularly in view of the multi-mode options. A slightly higher weight would be acceptable because it is already a heavy "tablet", and an extra 250 grams (~9 oz) would not much of a difference.

Flexible and fast in use, but flaws in manufacturing, only few interfaces, and poor maintenance options.

The Yoga 15 does not fulfill the criteria of a thoroughly well-conceived standard ThinkPad. Components, input devices and screen are good if not perfect, but the casing's stability suffers under the 15-inch form factor and the relatively slim chassis.
