Notebookcheck's Top 10 Convertibles

Staff (translated by Martina Osztovits), 01/09/2016

January 2016 update. Here you will find the best convertibles reviewed by Notebookcheck in the last few months. Our list of top models is regularly updated, maintained and commented on and should assist in purchase decisions.

For the original German article, see here.

Convertibles, also known as Two-In-One or Multimode-PCs, are hybrids which can equally well be used as tablet and laptop. There are many different kinds: docking tablets with a keyboard base, slider solutions over a fixed keyboard unit or Clamshell chassis with 360 degrees hinge. Prospective buyers will certainly find the solution most convenient to them. In the meanwhile, many manufacturers offer docking tablets as well as 360 degree solutions. Lenovo has been a pioneer with its Yoga models for business and consumers.

New reference of 2-in-1 devices: Microsoft Surface Book
New reference of 2-in-1 devices: Microsoft Surface Book
Editor's Choice in November 2015: Surface Book Core i5
Editor's Choice in November 2015: Surface Book Core i5

The new star in the convertible world is called Surface Book and stems from Microsoft. With its striking, futuristic Fulcrum hinge, which resembles the Watchband hinge of the Lenovo Yoga 3 Pro, the keyboard dock is connected to the tablet in a stable way. Certainly the Maxwell GPU Geforce 940M (rarely: GDDR5) is a technical highlight. It is beneath the keyboard and does not always have an impact on the power consumption of the tablet. For example the gaming performance can stay at home, while the Core i5 with active cooling delivers notebook performance with its frugal Intel graphics. So, the 13.5-incher is one of the attempts to combine tabet use and laptop performance in a single devices with the fewest compromises. Is it successful? Our reviewers think so. However, buyers can expect this for such a high price.

You'll get hardware without compromises for $1500. Actually, detachables are renowned for being top-heavy, but the Surface Book delivers one of the stablest solutions so far.

The display is better than good. Already the 3:2 format makes for envious glances. In addition, there are an extremely high contrast and an excellent brightness, which is also available on battery. Those who want best display quality will also enjoy the 3200 x 2000 resolution, best color precision and almost 100% sRGB coverage. Finally, the Windows convertible does no longer perform worse than smartphones with AMOLED display and best contrasts/viewing angles. A fast NVMe SSD and comfortable input devices make the bundle complete. Depending on the brightness, the battery life ranges from just under 7 hours to 10 hours in realistic scenarios. The reviewers cannot confirm rumors about poor battery runtimes because of high power consumption.

Nevertheless, it hails critique, in particular because of the poor connectivity: There is neither an HDMI-out nor WWAN. The tablet of the Surface Book only provides a 3.5 mm jack. A second storage solution is just as little possible as maintenance. Upgrade options are virtually non existent. The buggy software undocking is somewhat annoying and our reviewers think that the waste heat at keyboard and tablet is slightly too high. We could not observe the flickering problem in our test, since this probably only occurs with Visual Studio. In the meanwhile, Microsoft has announced a patch.

The Surface Book is definitely one of the highlights in 2015 and those interested in 2-in-1 solution should definitely take a closer look. We had a final US model under review. In Germany it will be available at the beginning of the coming year at the earliest.

Classic: HP EliteBook Revolve 810 G3
Classic: HP EliteBook Revolve 810 G3

HP's EliteBook Revolve 810 G3 is a classic with its swivel hinge. The 11.6-inch device is relatively heavy at 1.4 kg (~3.1 lb) and the bulky height of 22 mm (~0.9 in) does not appear to be relevant in the business range. However, the Revolve 810 delivers where it is important: a bright, contrast-rich IPS display accompanies a very good keyboard. The fast SSD works silently. The Intel Core i7-5600U usually does so, too, although it is actively cooled. The processor is not a Core M. The device hardly gets warm and even has a maintenance hatch.

A 3-year warranty completes the bundle. However, a starting price of 1750 Euros is to be expected. The low HD resolution of the Revolve 810 G3 is absurd. Currently, FHD is not even an option. Sometimes, things are different in the business range and the consumer range. Therefore, HD could actually be the preferred choice of users for 11-inch devices. Is the device too expensive for you? The Toshiba Portégé Z20-B convertible is an alternative (place 5).

Microsoft Surface 3
Microsoft Surface 3

Is the Surface 3 the next generation of notebooks? With a Kickstand and optional Type Cover, the Surface 3 should be able to replace a laptop - at least in a low-performance scenario. Actually, the progress bar often appeared to be stuck during copying and installations. This is not due to the brand new and faster Intel Atom x7 Z8700 (Cherry Trail). The Surface 3 is slowed down by its slow eMMC. This is annoying since otherwise the performance would be easily sufficient for everyday tasks. Charging is also slow. Since the power adapter is too small, the battery needs eight hours (device in use) for a full charge.

In terms of practical use during a multi-day air journey with many different locations, we were constantly faced with the problem of not getting enough energy into the device during possible charging periods to be able to work on the move for an extended period afterwards.

Apart from these major weaknesses, the Surface 3 also has a lot to offer. We appreciated the high-quality case and the very good display. A good battery life of about seven hours in the Wi-Fi test is impressive and the silent operation is still standard for Intel Atom devices. The expensive bundle also includes an update to Windows 10 as well as Office 365 for one year. Those preferring a larger size should consider the Surface Pro 4, which is currently awaiting its launch. The Surface Pro 4 has a slightly larger display (12.3 inch, resolution: 2736x1824) and is more powerful thanks to a 6th generation Intel Core M3, i5 or i7 processor. Microsoft will offer the device in place 1 in Germany soon for those you want even more laptop performance.

Elegant device: Lenovo Yoga 900-13ISK 80MK
Elegant device: Lenovo Yoga 900-13ISK 80MK

Honor where honor is due. The Lenovo Yoga 900-13ISK 80MK does things right in a big way. Its metal hinges do not only look good, they also are stable and high-quality. The glossy QHD touchscreen (3200 x 1800 pixels) is impressive, especially in color precision and brightness. However, the contrast it not the best. 400:1 are quite poor for an expensive high-end system. The system comes with a Skylake processor, but lacks a dedicated graphics card. You can do without the latter. In return, there is a fast Samsung SSD PM871 with a capacity of 512 GB. The reviewer praised the quiet dual fan system and the low surface temperatures. It is rare that the components can be easily reached and a USB-C with video out is on board. The battery life of just under seven hours is quite good, but competitors like the MacBook Air 13 2015-03 or the Microsoft Surface Book Core i5 perform better in this aspect.

Unfortunately, the CPU throttles under permanent load and the keys could have a longer travel. Moreover, the long charging time and the small touchpad are annoying. Microsoft's Surface Book is probably the best option, but the HP Spectre 13-4001ng x360 is impressive, too.

Geforce Business: Lenovo ThinkPad S3 Yoga 14
Geforce Business: Lenovo ThinkPad S3 Yoga 14
Editor's Choice in July 2015: Lenovo ThinkPad S3 Yoga 14 with Geforce 940M
Editor's Choice in July 2015: Lenovo ThinkPad S3 Yoga 14 with Geforce 940M

Lenovo's ThinkPad S3 Yoga 14 presents itself as business convertible. It brings the 360-degree hinge of the consumer world into the business range. Those who want to benefit from this flexibility in the workplace, do not have to dig that deep into their pockets: The entry level model with i5 and hybrid SHD is available from 999 Euros (~$1139), the premium model with GeForce 940M, 256 GB SSD and the same CPU costs 1130 Euros (~$1289) without an operating system. The tester really liked the elegant metal chassis combined with flexible and stable hinges. As befits a ThinkPad, the input devices feature an excellent feedback. Even the speakers of this business device sound good. Thanks to IPS technology, the semi-reflective touch display has an acceptable contrast, good colors and wide viewing angles.

The very good battery life is just under eight hours in the Wi-Fi test. Fast SSD and gaming capable graphics card make up a powerful bundle. The included Active Pen emphasizes the ThinkPad S3 Yoga 14's professional claim. This pen, which can be stored in the device (mounting), allows precise working on the desktop.

There are also drawbacks: The Yoga 14 lacks security features and a recovery partition. The latter is not true for all Yoga 14 devices, but depends on the shop. The 14-inch device is also available without an operating system.

Dead smart: HP Spectre 13-4001ng x360
Dead smart: HP Spectre 13-4001ng x360

Those who want all in one - 13-inch notebook, tablet, high-quality casing, and long battery life - can stop searching. With the HP Spectre 13-4001ng x360, there is a convertible that could even delight our tester. The robust, good-looking uni-body case with a low weight is a joy and many will look at it with envy. As with the Lenovo, several modes are possible thanks to the 360-degree hinge. There are many interfaces for a 13-inch device. Mini DisplayPort, dual-band Gigabit Wi-Fi, and Ethernet via adapter can even satisfy special requirements.

The TFT has a resolution of 2560x1440 pixels and has very wide viewing angles thanks to IPS. However, the contrast suffers from high black value and is only 549:1. The color representation compared to sRGB is not perfect, but profiling or our color profile can significantly improve it.

It is easy to open the case (bottom panel, screwed), which makes partial maintenance possible. The input devices with strong feedback (HP Control Zone - ClickPad) can also satisfy professional typists (quiet). Everybody will like the bright QHD IPS display with strong colors. Wide viewing angles and great colors please the eyes. The 13-inch device is fast enough for the Office and more, and the SSD does a good job. The quiet fan was annoying for the tester only during the stress test. While idling, passive cooling is sufficient most of the time and the convertible falls completely silent.

The poor sound of the speakers and the glossy display surface (sometimes troublesome outdoors) are a few of the drawbacks. With a current price of 1249 Euros (~$1419), the Spectre 13-4001ng x360 delivers a good price-performance ratio , but it is not significantly better than the Aspire R13 R7 or Transformer Book 300 Chi. However, HP has a better quality and more elegant case. The successor with Skylake processor is already ready, the Spectre x360 13-4104ng with Core i5-6200U (K3D43EA), which we are currently reviewing.

Toshiba Portege Z20t-B-10C
Toshiba Portege Z20t-B-10C

An expensive runtime wonder was the title our tester chose for the Toshiba Portege Z20t-B-10C. The 12.5-inch device does not feature a fan and is equipped with an Intel Core M 5Y71 (Broadwell) and a 256 GB SSD. There is an acceptable processing performance inside. Together with the keyboard dock and the digitizers, make up a fully-fledged work device. In addition, the battery life of just under 13 hours in the Wi-Fi test is impressive. It was made possible by the auxiliary battery in the dock and the frugal Core M.

Meticulous workmanship, high-quality input devices and the anti-reflective IPS panel with flawless image quality are pleasing. However, they cannot justify the extremely steep price of 2000 Euros (~$2273). Customers only get a 12-month warranty and not even a fingerprint reader. At least the connectivity is very good for a convertible with LTE module, HDMI, VGA and type-A USB. Unfortunately, the Z20t does not provide maintenance possibilities and the batteries are fixed.

For workaholics: Acer Aspire R13 R7-371T-779K
For workaholics: Acer Aspire R13 R7-371T-779K

Acer's Aspire R13 R7-371T-779K is a versatile all-in-one hybrid, i.e. it is a tablet, notebook and multi-mode laptop in one device. The display can be rotated around its long axis, which allows many different positions. We liked the delicate-looking, yet stable and premium chassis. The input devices perform just as well and even office workaholics could be satisfied with them. Thanks to its versatility, the Aspire R13 is suitable as a work device, but with two SSDs in RAID-0, Core i7-4510U (Haswell) and 2560x1440 pixels in the display, it is already targeting professionals who know exactly when they benefit from a 3K touch panel (WQHD). The display features natural and vibrant colors with hardly any clouding, despite good brightness. The price of 1500 Euros (~$1705) is very ambitious, but you will get a premium convertible including Acer's Digitizer Pen. The Skylake successor, the Aspire R13 R7-372T with Core i7-6500U and Intel HD Graphics 520 is already in sight.

Great keyboard: Lenovo ThinkPad Helix 2
Great keyboard: Lenovo ThinkPad Helix 2

The first version of the Helix with an Ivy Bridge processor has already tried to be a business convertible with the best possible list of features, where you do not have to make any compromises in terms of productivity. For almost 1400 Euros (~$1591) not only do you get a table with an excellent keyboard (UltraBook Keyboard), but also an LTE modem as standard. Sadly, the build quality and the case stability cannot really meet the premium claim. It is possible to twist the tablet with little force and the result is creaking sounds, which is not reassuring in terms of product quality. In addition, there are visible gaps. The tablet can only be attached to the keyboard at an angle of 120 degrees, or you can put it down when you want to transport it. Flexible hinges are only available with the more expensive UltraBook Pro Keyboard. The old Helix got hot under load and the cooling solution was insufficient. This is not a problem anymore thanks to the Intel Core M 5Y71 (Broadwell). The lower TDP results in less heat, but this is necessary since the Core M does not need a fan at all. Despite the drawbacks, the overall impression of the Helix 2 is very good thanks to the excellent IPS FHD display and the long battery runtimes of up to 6:36 hours (WLAN test).

Flexible but still standard: Lenovo ThinkPad Yoga 12
Flexible but still standard: Lenovo ThinkPad Yoga 12

Lenovo's ThinkPad Yoga 12 is the smallest device from the new ThinkPad series, which is available in 12, 14 as well as 15.6-inches and uses a 360-degree hinge. Convertibles are no longer a gadget for private users. According to Lenovo, business users are supposed to use the flexible devices. This might actually work with the 12-inch device because the manufacturer can use its strengths such as the good input devices, anti-reflective surface and picture quality. The Full HD IPS panel is very bright but still has a good contrast. The touchscreen is complemented by a digitizer pen, which is a useful addition. The battery is integrated, but it and other components can be accessed when the bottom cover is removed. The rather heavy weight of 1.58 kilograms (~3.5 lb) is obviously an issue when carrying the tablet in one hand. Unfortunately, TPM is the only security feature.
