La empresa Eden ha retirado más de 6.000 de sus garrafas de agua debido a una intoxicación que ha afectado a cerca de 700 personas en Barcelona.
Este tipo de empresas se dedican a la comercialización y distribución de agua envasada en garrafas para fuentes o dispensadores portátiles, garrafas que suelen estar presentes en lugares públicos y dispensarse a empresas, pero también se utilizan en domicilios particulares para consumo doméstico, especialmente en lugares donde el agua del grifo no presenta un sabor demasiado agradable.Eso sí, como ya advertimos en 2013, el agua que se dispensa en este tipo de garrafas no tiene las mismas garantías y protecciones que el agua de grifo.
Al estar envasada, lo lógico sería que como mínimo el agua de estas garrafas tenga las garantías sanitarias que se le exigen al agua embotellada comercializada en tiendas, que son menos estrictas que para el agua del grifo porque se permite cierta carga microbiana, pero no microbios patógenos, como los encontrados en las garrafas Eden. Además, sólo se le exige al agua de las garrafas que cumplan estos mínimos en el momento de envasado, no se alude a nada para el momento del consumo, como se pide al agua de grifo.El agua de estas garrafas carece del desinfectante que da seguridad higiénica al agua de grifo, por lo que cualquier manipulación o almacenaje incorrecto antes de comercializarse, puede aumentar la presencia de microbios. Además, estas garrafas se almacenan a temperatura ambiente hasta su consumo, sin ninguna precaución especial, por lo que aumenta el riesgo.
¿El esmero en su fabricación es suficiente para garantizar la calidad higiénica del agua en garrafa en el momento del consumo? Como vemos, no, o al menos no siempre.
OCU realizó en 2013 un estudio sobre el agua Aquaservice y resultó ser un agua de baja mineralización pero muy desequilibrada y agresiva, con una carga microbiana que sería inaceptable en un agua de distribución, por ofrecer menos garantías sanitarias. Pero estaba dentro de los rangos encontrados en aguas envasadas almacenadas. Si no tuviéramos acceso a agua de distribución, podría ser una alternativa válida. Pero no aporta nada que no tenga el agua del grifo de la mayoría de las ciudades españolas, y carece de seguridad higiénica.
Estos ordenadores unen lo mejor de dos mundos, puesto que son ultrabooks que se transforman en tabletas. Utilizan Windows 8 por lo que permiten instalar los programas clásicos para PC.
Se puede ocultar el teclado detrás de la pantalla o simplemente quitarlo y, como la pantalla es táctil, se puede interaccionar con las aplicaciones o redactar pequeños textos, como si de una tableta se tratara. Pero no se deben confundir con las tabletas con teclados, pues las funcionalidades son muy distintas.
En las pasadas semanas, hemos asistido a un espectáculo digno de patio de colegio. Microsoft y Opera se tiraron los trastos en público a costa de la eficiencia de sus navegadores. Ambas firmas hicieron públicas diferentes pruebas en las que, de manera 'sorprendente', sus navegadores eran los que mejor trataban las baterías de una tableta Surface, en el caso de Edge, y de un ordenador portátil, en el de Opera.
En Teknautas hemos querido salir de dudas por nuestra cuenta, y para ello hemos organizado una prueba con tres navegadores y un mismo ordenador portátil. Los navegadores que hemos probado son Chrome, Firefox, Opera y Edge y, por una vez, no nos queda otra que darle la razón a Microsoft. Edge ha ganado al resto con una ajustada victoria sobre Firefox.
Para hacer las pruebas, nos hemos valido de un par de portátiles idénticos. En concreto, se trata de un Asus VivoBook S200E, que cuenta con un procesador i3 2365M a 1,4GHz, 4GB de memoria RAM y un disco duro de 320GB. Y para ejecutar el test, hemos tirado de las últimas versiones disponibles de los navegadores. La versión de Edge era la 20.10240.16384.0, la 51.0.02704.103 m de Chrome, la 47.01 de Firefox y la 38.0 de Opera. No hemos incluido Safari ante la imposibilidad de probarlo en las mismas condiciones que el resto.
Nuestra primera intención al ejecutar la prueba era instalar una extensión que permitiera recargar una página web cada pocos segundos para forzar así al navegador a estar trabajando de manera constante. Pero Edge todavía no soporta los añadidos externos, por lo que hemos tenido que descartar esa opción ante la imposibilidad de encontrar una alternativa satisfactoria.
En su lugar, hemos optado por reproducir un vídeo de YouTube de una extensión lo suficientemente larga como para que ningún navegador pudiera sobrevivir al metraje conjunto del vídeo y de los anuncios. Ninguno lo ha logrado, aunque los resultados han sido dispares. Por la cola se encuentra Chrome, incapaz de sobrevivir a su mala fama. Nuestra prueba lo ha demostrado: ha aguantado en pie 2:09 horas.
Microsoft estaba en lo cierto con Edge: su navegador es capaz de aguantar más tiempo en pie. Todo lo contrario sucede con Chrome y Opera
¿Por qué ha finalizado en última posición? El consumo de recursos siempre ha sido un hándicap para el navegador de Google, que abusa especialmente de la memoria RAM para mantener las diferentes pestañas abiertas (aunque en nuestro caso, solo había una en marcha). Lo hace para que los diferentes procesos que están en funcionamiento en una pestaña sean independientes del resto y así optimizar la experiencia de uso. El peaje a pagar es ese consumo excesivo de batería.
El segundo en la lista ha sido Opera. A pesar de que el navegador sacó pecho recientemente y aseguró que su navegador era el que mejor cuidaba la batería, solo ha aguantado unos pocos minutos más que Chrome. En total, han sido 2:13 horas las que se ha mantenido en funcionamiento. Message déposé le 29.08.2016 à 05:11 - Commentaires (0)
HP 537626-001 Notebook BatteryThis is useful to pop up dictionary definitions within web browsers when words flummox you. Really, though, the absence of another traditional moving part has allowed Apple to shave a few millimetres off the MacBook's design. The standard feel of the trackpad Apple has pioneered is still there - namely, the most responsive and pleasing to use on the market.
The trackpad is big and a pleasure to use. It takes up a huge proportion of the area under the keyboard - by our measurements there's 84mm of non-trackpad, then the 112mm-wide trackpad, then another 84mm of chassis, so it's 40 percent of the horizontal space - and has a whisper-smooth top surface.
Where Apple has differentiated this MacBook line from its aging MacBook Air is in the screen. It's amazing. It has Apple's Retina display - but then again, so did the iPhone 4 in 2010. Why Apple has resisted adding such an impressive display to the Air is now slowly being answered by its inclusion here.The MacBook, in all current models, only ships with a 12-inch screen option. It has a 2304x1440 resolution at 226 pixels per inch. In real-life terms, it is one of the best screens we have ever seen on a laptop, with an outstanding range of colours and backlight brightness levels, the auto-adjustment of which is second to none in its accuracy. You can also scale the resolutions, the most useful being the 'More Space' option that pushes the 12-inch display to its most spacious for multitasking.In comparison to the cheaper MacBook Air, the screen has a better resolution but also a more pleasing screen-to-bezel look. Only since this laptop's design premiered in 2015 have people begun to consider the Air as looking a bit aged. The Air's thicker, plastic grey bezel now looks outdated and unnecessarily wide compared to the sleek, thin glass black bezel of the MacBook. It's a small touch, but adds to the premium look and feel of the device.
Straight up - the battery, despite the improvements, is not as good as the current crop of MacBook Airs and Pros. This comes down to simple physics: this computer is tiny, and Apple has done its best to cram as much battery as possible in there.The new Skylake processor performance allows for slightly improved battery consumption compared to last year's model, and Apple quotes up to 10 hours of wireless web use. Using the 2016 MacBook day to day we found we could go through the working day without having to plug the mains charger in.We noticed a sharper drop in the battery levels once you fire up a fair few tabs in Chrome (a famous MacBook energy sapper), along with apps like Mail, Slack, Notes and Google Drive, as well as video playback all chipping in now and then.
What we describe here is many people's daily work needs, and the MacBook offers more than acceptable battery performance for a laptop for these needs. All laptops decrease with this kind of usage. If you really balk at the 10 hours quoted, it's possible that you've been spoilt by the MacBook Air! And fair enough, if you need to push 15 hours away from a plug, coffee shop hopping and working on the go. Your job sounds chilled.
There's no escaping the fact that this is a very similar laptop to its 2015 predecessor, which so divided the tech community. But we think the problems have been overblown. The engineering on show is superb, and the performance is completely acceptable for a modern-day computer of this size. The arguments that there should be more ports on the MacBook only exist because people want one, and are frustrated that their current set-up needs will not allow for it.
Apple has undoubtedly improved the MacBook for 2016. It is a truly outstanding laptop that will be wrongly categorised as a luxury technological item. There's a difference between something costing a little too much and it being luxurious - just like the MacBook Air, this laptop deserves to fall in price and rise in specs to continue to be what we consider an excellent flagship computer. The world and its ports just need to catch up.The US Patents and Trademarks Office (USPTO) has granted Apple a mobile hotspot device patent application, which the company filed last year, that describes a battery-powered device designed purely to provide wireless connectivity to other hardware.The patent, granted yesterday, shows several configurations of the mobile hotspot, including three different-sized units in the shape of an AA battery. Apple envisaged one end of the cylindrical device containing up to a 1000mAH battery, while the other houses electronics like a SIM card.
Apple notes the device could alleviate the battery drain caused by using a phone as a hotspot. Also, phones aren't ideal to lug around just for mobile connectivity while doing sports or other activities when, for example, the Apple Watch might be used.Apple was also granted patent number 9,397,387 for an "electronic device with isolated cavity antennas". It was granted a similar patent in 2012, giving rise to speculation at the time that Apple might embed a mobile chip in its MacBook. Four years on and Apple still hasn't put a 4G chip in any of its OS X devices. However, hopes are being kept alive by several patents that suggest Apple might do it in the future.This patent describes a device that may have "wireless communications circuitry that operates in long-range communications bands such as cellular telephone bands" as well as Wi-Fi circuitry.
Another patent the USPTO granted Apple in May was for an "electronic device with dual clutch barrel cavity antennas", which contains the exact same wording regarding cellular circuitry.However, in both patents, the devices used to describe the cellular capability include phones, a media player, a gaming device, a laptop, a tablet, a desktop computer, a display containing an embedded computer, and a television or set-top box.While many people would appreciate a cellular option for the MacBook, it would be interesting to see if they're willing to fork out the extra $100 or so for not having to rely on their smartphone for connectivity. Then again, as Apple's mobile hotspot patent demonstrates, you wouldn't need to rely on the iPhone's already short battery life for your connection.
New laptops from the biggest names in the tech industry are expected to be released before the year ends. The likes of Apple, Lenovo and Microsoft are making the rounds when it comes to rumored laptops. However, there is one laptop that is reportedly better than the much talked about MacBook Pro 2016 – the 2016 Dell XPS 15.
Since it remains to be seen if Apple will unveil a new MacBook Pro this year, tech experts have found that the XPS 15 is a potential competitor against Apple's alleged flagship laptop.In a report by Forbes, Dell's update to the XPS 15 laptop is being compared to the Apple's rumored MacBook Pro update. The report mentioned that Dell's iteration has a bigger display size, measuring at 15.6 inches, which is slightly bigger than the MacBook Pro. Despite this size, Dell managed to maintain the lightweight feature of the device, weighing only 4.4 lbs with the battery, which makes it a mobile PC.
The XPS 15 somehow carries attractive specs that would be hard for one to ignore. The device runs on a Windows 10 system. The entry-level variant has a screen resolution of 1080 pixels, but for those who are willing to shell out more money, they can get a 4K Ultra HD resolution. The Intel Skylake processor, coupled with 16 GB of RAM, gives it power and smooth speed. On board for the graphics is NVIDIA GTX 960M.
Battery life is also impressive for the XPS 15. It can last all day after a single charge. With little adjustments, a user can see just how long-lasting the battery is – this means adjusting the display brightness and avoiding watching too many movies or playing games. Dell can also include Dell Power Companion, a portable charger that makes sure the battery doesn't die out, especially when the device is taken out for long trips.
For years, consumer tech companies have dreamed of convergence — that is, the idea of one device being the nexus of all your computing needs.Basically, they’ve tried really hard to have you buy a smartphone (the computer you carry in your pocket) that's also your laptop (the computer you use at home).Microsoft has been the most visible proponent of this idea in recent months; its Continuum feature allows Windows Phones to run a lightweight version of Windows 10 when plugged into a display dock. The problem, in a nutshell, is that nobody buys Windows Phones.Before Microsoft, there was Ubuntu. It’s long struggled to gain traction with similar promises, dating all the way back to its failed Edge project in 2013.
Before that, there was Motorola. Its Atrix phone worked the same way, but its laptop dock cost $500, the software you used with it was half-baked, and the phone was only “strong” by 2011’s standards. Again, few people cared.Still, the dream hasn’t died. The latest group to give it a try is Andromium, a startup headed by alumni of Google and Y Combinator. Its new Kickstarter project, the Superbook, essentially flips the Atrix concept, and applies it to various Android phones
At its core, the Superbook is just a laptop shell. It’s got an 11.6-inch display with a 1366x768 resolution, a QWERTY keyboard with Android-specific keys, a multi-touch trackpad, and a battery that Andromium rates at eight or so hours of use. (Though that’ll move closer to 10 hours if Andromium reaches $500,000 in funding, which currently looks likely.) In a recent Reddit AMA, the company said the device is composed of soft plastic.

Acer TravelMate 6592G Notebook BatteryBattery life is decent for a Windows tablet, and we managed to get 6 hours and 39 minutes in PCMark 8's battery test. Real world usage also yields similar results, just as long as you stick to non-CPU-intensive tasks. The 10W charger isn't powerful enough to juice up the tablet quickly, so topping it up all the way is a long wait. As far as tablets go in general, battery life could have been better.
The Notion Ink Able 10 is available exclusively through Snapdeal at Rs. 24,990, which is not bad for the package on offer. It would have been more disruptive had they priced it the same as the Cain (around Rs. 20,000) but maybe we'll see it discounted in a couple of months.There are a few niggles you need to be aware of. The tablet is heavy, so holding it for long durations isn't very comfortable as fatigue sets in pretty quickly. The trackpad is glitchy, and often misinterprets gestures or even fails to respond. Battery life, while good for a Windows machine, is still lagging behind that of comparable tablets, and charging the Able 10 all the way is a painfully slow process. Finally, the cameras are pretty weak which is not good if you do a lot of Skype calls.
Having said that, the Able 10 trumps most other budget Windows 2-in-1s due to its compactness, ample RAM, and good amount of storage. You'll have enough room for installing more apps even a year down the line. The build quality is also good; the display is fairly vivid; you get a good set of connectors; built-in 3G; and a solid keyboard which completes the tablet-to-laptop transformation nicely.Download the Gadgets 360 app for Android and iOS to stay up to date with the latest tech news, product reviews, and exclusive deals on the popular mobiles.As the (overdue) update of Apple’s MacBook Pro tumbles into the second half of the year, there’s a Windows 10 laptop that could be a painless alternative for even diehard MacBook users.
First things first. Windows 10 is a no-no for some. But even for those with a longstanding aversion to Microsoft’s operating system, Windows 10 is a galactically big improvement over all previous versions. In fact, when I switch from one of my MacBooks to one of my Windows 10 systems (which I do regularly), it’s easy to forget that Apple’s OS is “better.”That said, I’ve been spending a lot of time with the 2016 update of the XPS 15 during the last month and it’s a scary-good machine. The Dell XPS 15 is where the next 15-inch-class MacBook Pro (or whatever Apple calls its next high-end MacBook) is headed. Here are some of my thoughts comparing the XPS 15 with what Apple will likely include on the future MacBook Pro.
Wow, that’s a big display: go bigger than Dell’s 15.6-inch display and you’d have a movable desktop. Dell, however, has managed to keep the footprint closer to some 14-inch laptops with its almost-borderless display. And an attractive carbon fiber weave wrapped around the keyboard and touchpad allows Dell to keep the weight down to 3.9 pounds (4.4 pounds with the larger battery). The upshot: the XPS 15 has a bigger display but weighs less and has a smaller chassis than the MacBook Pro. No small feat and something for Apple to keep in mind. (Well, actually, the next MacBook Pro design is probably already fully baked so let’s hope Apple has done something innovative with the chassis.)
Surprisingly, Dell has been the only top-tier manufacturer to make borderless displays a centerpiece of its laptop design (though others are now catching on). And there’s a reason that Dell crows about the XPS’ “bezel-less” border: it makes for a really cool-looking laptop in addition to keeping the weight and size down. Dell has also done this with great success on the XPS 13, essentially a smaller version of the XPS 15.If you opt for the 4K Ultra HD (3,840-by-2,160) touch display on the XPS 15, you get 3 million more pixels than the Retina display on the 15.4-inch MacBook Pro. The XPS 15 I’m using has the 4K Ultra HD display. At the risk of stating the obvious, you don’t want nor do you need an external display when you have a display this big and this good affixed to your keyboard. Besides, a large 4K-class external display as good as the XPS’ display would cost you a small fortune.
But a tiny connector: In addition to the usual ports (USB Type-A, HDMI), the XPS comes with one (tiny) USB-C/Thunderbolt 3 (40Gbps bi-directional) port but I expect Apple to include more. After all, Apple was the first computer maker to give USB-C real credibility/notoriety when it used the connector for the first time on the impossibly-thin 12-inch MacBook, introduced in April 2015. The beauty of USB-C of course is that it engenders thin designs (the XPS 15 is only 0.66 inches at its thickest point) but is still very fast.Intel INTC +1.17% Skylake (mobile 6-core in the offing?): the XPS 15 I have packs Intel’s newest i7-6700HQ 6th generation quad-core processor. This is the most glaring anachronism in the current MacBook Pro 15, which reaches back in time to the Intel Haswell processor (which first debuted in the summer of 2013). Will Apple leap-frog two Intel processor generations to Kaby Lake? Probably not but it will be refreshing to see a 6th Generation Intel Core processor in a MacBook Pro. Processor propellerheads take note: during a conversation I had recently with an executive at a top-5 global PC maker, I was told that 6-core Intel processors for laptops are on the way. When/if it happens, I expect Apple to follow suit.
Final thoughts: Dell eschews the all-aluminum chassis prevalent today. The only downside is that the carbon fiber can be a body oil magnet (be prepared to use a soft cloth moistened with soapy water every other day to keep the area around the trackpad free of oily buildup.) The rest of the laptop (top and bottom) is aluminum. Overall, a remarkably sturdy laptop considering its light weight and thickness – only 0.66 inches at its thickest point.I have to admit that I’m partial to Apple’s all-aluminum designs. So, unless Apple has come up with revolutionary new material, I’m fine with another all-aluminum MBP. I love the feel of the aluminum on my 12-inch MacBook and wouldn’t want anything else.
And a bit more about the XPS 15′s performance…One of the best things about big-screen laptops is the desktop-level speed. A wide chassis allows robust cooling systems and fans to keep even the speediest silicon from overheating most of the time. And, yes, fast silicon does make a big difference. There really isn’t anything that can slow down the XPS 15. Opening a browser with dozens of tabs or playing a 1080p video while crunching an Excel spreadsheet or doing photo editing…nothing will faze it. And while I don’t play games, it can also keep up with some of the faster gaming laptops, based on reviews at reputable tech sites. All of that speed can make it painful to return to less performance-oriented laptops.
Price: Pricing starts at $999 with a standard-resolution (1,920-by-1,080) display, dual-core processor, and 500GB 7200RPM hard drive + 32GB solid state drive. The price jumps into the $1,600 to $2,950 range if you go with the high-resolution display, a quad-core processor, and opt for either a 256GB or 512GB PCIe solid state drive. (My unit comes with the 512GB SSD.)Recently, Microsoft compared Microsoft Edge’s battery efficiency against Google Chrome, Opera, and Firefox. The company announced that Microsoft Edge consumes 70% less battery than Google Chrome. As you may expect, Microsoft Edge won the test because of the optimizations the browser includes. However, Opera then did their own test in which Opera beat Microsoft Edge. Opera’s test wasn’t exactly fair as they tested Opera with the built-in ad-blocker enabled — on the other hand, Microsoft didn’t use any ad-blockers during its own test. Now, the folks over at PCWorld did their own battery test for all of the leading browser — and unsurprisingly enough, Microsoft Edge won:
Ditto on DDR4: The XPS 15 I’m using comes with 16GB of DDR4 RAM, it’s a no-brainer for Apple to do the same. Greater Graphics: most of the Dell XPS 15 configurations come with an Nvidia GTX 960M graphics chip. Apple will undoubtedly update its MacBook Pro with either the latest AMD or Nvidia graphics.Battery life: my unit has Dell’s extra-large 84Whr battery so the XPS 15 can stay charged all day based on my usage pattern. But that requires turning down the display brightness to about 60 percent and not spending a lot of time watching movies or playing 1080p games (I’m not a gamer anyway). Battery life will jump if you opt for the cheaper version of the XPS 15 with a less-power-hungry, standard-resolution display. And Dell has also supplied me with a Dell Power Companion (see image at top) that can extend the battery life for hours more. I carry it in my bag wherever I go but have not needed to use it yet. Battery life is Apple’s strong suit so I expect that the next 15-inch class MacBook Pro to excel on battery run time. The question is, how will Apple perform it’s usual battery-life magic? With which Intel 6th Gen chip and with what type of new power-frugal LCD tech?
As you can see in the above results, Edge was followed by Chrome, Opera, and then Firefox. Internet Explorer 11, on the other hand, came last which isn’t really a surprise. In case you are wondering, PCWorld used EMBC BrowsingBenchmark to perform the tests on their Toshiba Radius 12 (Core i7 Skylake CPU, 8GB of RAM, an Ultra HD 4K Panel, and a 41-watt battery).Microsoft has been focusing a lot on performance and efficiency with Microsoft Edge. The company recently announced some changes that are coming with the upcoming Windows 10 Anniversary Update that will improve the JavaScript performance on Edge. Nevertheless, tell us what you think of PCWorld’s battery test in the comment section below.
Feature-wise, this model has a sixth generation dual-core 2.5GHz Intel Core i7-6500U processor, integrated Intel HD Graphics 520, 8GB of RAM, a 256GB solid-state drive, three USB 3.0 ports, an HDMI port, Bluetooth, and 802.11b/g/n/ac WiFi support. As for the 13.3-inch screen, it benefits from in-plane switching, WLED backlighting, and a QHD+ resolution of 3200×1800.From the position of portability, this HP Envy is a good fit for heavy travelers. It weighs roughly three pounds, measures a bit over half an inch thick, has a back-lit keyboard, and the three-cell 45WHr battery can offer up to seven and a half hours between charges.Keep in mind, you’ll need to manually configure this setup on HP’s site. First, load up the product page, and press the “Customize & buy” button. On the next page, be sure to select the i7-6500U CPU, the 3200×1800 display, and the 256GB drive before adding it to your cart.
While this configuration lists for $1229.99, HP is selling it online for just $1129.99. Better yet, applying coupon code “HPBTS2016NB” during checkout will save you an additional $207.50. And since HP offers free shipping, you’re only left spending $922.49 on this incredible little notebook.Our commerce group sources the best deals and products for the ET Deals posts.

As classrooms become increasingly high-tech, it's out with the old composition notebooks, and in with the chromebooks. The Asus Chromebook C202SA-YS02 ($229) is crafted with kids in mind and features a rugged design with a spill-resistant keyboard. Though it's a bit thicker than similar chromebooks, and can be a little sluggish when running multiple browser tabs, its long battery life, affordability, and modular design, make it a solid choice for use in schools. Still, the Acer Chromebook R 11 remains our top pick for its strong performance, superior local storage, and convertible design, but it will cost you more. If you're on a strict budget, the Chromebook C202SA-YS02 is worth a look. Message déposé le 24.08.2016 à 04:15 - Commentaires (0)

Built for small-to-medium-size businesses with big requirements and modest budgets, the ThinkPad L460 offers a great mix of durability, security and usability, all at an affordable price. Starting at $692 ($1,056 as configured), this 14-inch laptop is less expensive than Lenovo's ThinkPad T460 and competitors like the Dell Latitude E7470, but still offers a sharp screen, best-in-class keyboard, MIL-SPEC-tested chassis and more than 12 hours of endurance. The ThinkPad L460 cuts a couple of corners, but provides first-class productivity and plenty of value for the money.
The ThinkPad L460 has the same, simple, black aesthetic as most of Lenovo's other business laptops, but it is made of cheaper-looking material than its more expensive siblings. Where the ThinkPad T460 has a smooth, glass-fiber-reinforced chassis, the L460's ABS/PC plastic chassis has a rough surface that just doesn't have the same, premium feel. However, the body feels very solid and sturdy, with hinges that seem especially tight.Though light enough to carry around all day, Lenovo's laptop is noticeably thicker and heavier than both its competitors and its slightly pricier sibling. The L460 measures 13.34 x 9.23 x 0.95 inches and weighs 4 pounds with its three-cell battery, or 4.4 pounds with its optional six-cell battery. The Lenovo ThinkPad T460 is 0.12 inches thinner and 0.4 pounds lighter, weighing 3.8/4.2 pounds with its three- and six-cell battery options. Dell's Latitude E7470 (3.13 pounds, 13.19 x 9.13 x 0.74 inches) out-slims both Lenovos, while Toshiba's Tecra A40-C (4 pounds, 13.4 x 9.6 x 0.94 inches) is about the same size as the L460.
The ThinkPad L460 is designed to withstand some abuse. According to Lenovo, the laptop has passed MIL-SPEC 810G tests for extreme temperatures, shocks and vibrations. Like all ThinkPads, it has also undergone internal bump and stress tests to make sure it can handle getting knocked around as you travel. The spill-resistant keyboard takes small water splashes and drain them out of a hole in the bottom of the system.IT managers will appreciate the ThinkPad L460's solid security features, including TPM encryption and optional Intel vPro manageability. You can also configure the laptop with a smart-card reader ($10) and fingerprint reader ($20).The ThinkPad L460's 14-inch, 1920 x 1080, matte display offers accurate colors, sharp details and solid viewing angles. When I watched a trailer for Ghostbusters, fine details such as the dirt on a subway wall or the reflections on a hood ornament appeared prominent. The green and blue glow of the ghosts seemed true, though not overly rich. However, many objects, particularly skin tones, seemed to have a slight red bias. Colors stayed true at up to 80 degrees to the left and right, washing out only slightly at a full 90 degrees.
According to our colorimeter, the L460 can reproduce 67 percent of the sRGB color gamut, which is a bit below the 14-inch laptop category average (80 percent) but identical to the ThinkPad T460's score. The Dell Latitude E7470 (118 percent) and Toshiba Tecra A40-C (72 percent) both did better.The L460's screen is also quite accurate, achieving a Delta E error rating of just 0.25 (0 is perfect), which is far better than the category average (2.23) and about on par with the scores of the Latitude E7470 (0.5) and ThinkPad T460 (0.5)Registering 233 nits on our light meter, the ThinkPad L460's display is just a little dimmer than the category average (246 nits) but nearly identical to the showing by the T460's panel (239 nits). However, the Latitude E7470 (338 nits) was quite a bit brighter.
With the L460's powerful, bottom-mounted speakers, you'll have no problem giving audio-visual presentations to a giant conference room full of people. When I played AC/DC's "Back in Black" on the laptop, the volume was loud enough to fill the entire first floor of my house. There was a clear separation of sound between instruments on the left and vocals on the right. Though there was some major tinniness at maximum volume, the output was richer and more accurate than on most laptops we test. The bundled Dolby Audio app lets you choose from among presets for different sound-types -- Movie, Music, Game and Voice -- though I found the catchall Dynamic mode sounded best.
Even among Lenovo's business laptops, which have a reputation for providing typing comfort, the ThinkPad L460's keyboard stands out as one of the best. The gently curved chiclet keys offer a very deep 2.1mm of travel (1.5 to 2mm is typical) and a level of tactile feedback that provides just the right amount of resistance, without becoming stiff. Thanks to the keyboard's snappy feel and generous travel, I reached a rate of 107 words per minute with an error rate below 1 percent on the 10FastFingers test. That's one of my best scores ever and far above my typical, 96-wpm and 3 percent mark.
Unfortunately, for those who need helping finding their keys in the dark, the ThinkPad L460's keyboard doesn't have a backlight option.Like most other ThinkPads, the L460 has a red TrackPoint pointing stick between its G and H keys. Navigating the desktop, clicking on icons and highlighting text was extremely accurate with the little red nub, and best of all, I never had to lift my hands off of the home row, so I could work faster.For those who don't like pointing sticks, the L460 also has a 3.9 x 2.2-inch touchpad. The buttonless pad offers mostly accurate navigation around the desktop, but it was occasionally jumpy, and sometimes the pointer stuck and I had to pick up my finger and swipe again. On the bright side, multitouch gestures such as pinch-to-zoom and three-finger swipe worked flawlessly.The ThinkPad L460 makes room for almost every port a business user could want, including a VGA connector for outputting to old-school monitors and projectors. The left side houses a mini DisplayPort, Ethernet, VGA, a Kensington Lock slot and two USB 3.0 ports. The right side contains the 3.5mm audio jack, optional smart-card reader and a third USB 3.0 port. The front lip holds an SD Card reader. Unfortunately, there's no USB Type-C or Thunderbolt 3 port for the next generation of peripherals.
The 720p webcam captured colorful, detailed images of my face in both a dark room and under the fluorescent lights of my office. As with most laptop cameras, the images had some visual noise and splotchiness.With a Core i5-6200U CPU, 8GB of RAM and a 256GB SSD, our review configuration of the ThinkPad L460 offered strong performance for multitasking and productivity. Even with more than a dozen tabs open and a 1080p video playing in another window, I was able to switch tasks and work on this review without a hint of lag.Lenovo's laptop scored a solid 6,245 on Geekbench 3, a synthetic benchmark that measures overall performance. That's slightly behind the 14-inch laptop category average (6,475) and the Core i5-6300U-powered Lenovo ThinkPad T460 (6,708), but the Latitude E7470 (6,059) and Toshiba A40-C (5,846), which have the same CPU as the L460, both fared worse.
The L460 took just 4 minutes and 32 seconds to complete our spreadsheet macro test, which involves matching 20,000 names with their addresses in OpenOffice Calc. That time is much faster than the category average (5:52) and about on par with the Latitude E7470 (4:30) and Tecra A40-C (4:30). However, the T460 (4:13) was 19 seconds quicker.The laptop's 256GB SSD copied 4.97GB worth of mixed-media files in just 32 seconds. That's a rate of 157.1 MBps, comfortably ahead of the category average (137.5 MBps), the Latitude E7470 (132.3 MBps) and the hard-drive-powered Tecra A40-C (27.9 MBps). The Thinkpad T460 was a tad faster, though (175.5 MBps).
With integrated Intel HD 520 graphics, the ThinkPad L460 is powerful enough to play videos and do some light media editing, but we wouldn't recommend gaming or doing 3D modeling. Lenovo's laptop scored 62,267 on 3DMark Ice Storm Unlimited, a synthetic test which measures graphics prowess. That's higher than the category average (56,655), the Latitude E7470's score (59,801) and the Tecra A40-C's showing (54,373) but about 5 percent behind the T460's mark (65,981).
The ThinkPad L460 can last a long time on a charge, depending on which of its three removable batteries you choose. With its high-capacity battery, which has six cells and can store 72 watt-hours of juice, the laptop lasted a strong 12 hours and 51 minutes on the Laptop Mag Battery Test, which involves continuous surfing over Wi-Fi. That's more than 4 hours longer than the category average (8:22) and far ahead of the Latitude E7470's time (9:16) and Tecra A40-C's showing (6:44). However, with a high-capacity battery on board, the ThinkPad T460 lasted for a whopping 17hours and 4 minutes. Message déposé le 23.08.2016 à 10:33 - Commentaires (0)
