Dell Inspiron 5100 Battery

The Pixel C is Google's Android-based answer to the Surface. It's a powerful tablet with a beautiful screen and an optional magnetic keyboard that doubles as a screen cover. Though Google doesn't have an active pen for it, there is a third-party one that works with it. The Pixel C has been around since September 2015 and supplies appear to be running low. Currently only the 64GB version appears to be readily available for $599.Whether we're talking about the original 12.9-inch model or its smaller 9.7-inch linemate, the Pro is Apple's attempt to turn its tablet into a laptop substitute as well as a pen-enabled creative tool. The iPad Pro runs on the company's mobile OS, iOS 10, instead of Apple's MacOS, however. Pricing starts at $800 for the 12.9-inch and $600 for the 9.7-inch, though both are available at discounted prices. These discounts lend some credence to rumors the Pro will be replaced as soon as March.Mobile networks have a hard time handling emergencies that send us all rushing to our phones to get the latest information or reach friends and family. A new Weather Channel app, though, can get the message through even during earthquakes, tornadoes and terrorist attacks when mobile networks can be overwhelmed and may not work.

The Android app, geared specifically for developing countries, uses IBM-developed technology called mesh networking that sends messages directly from one phone to another. The result is that information can propagate even when centralized networks fail.Using Bluetooth and Wi-Fi networks, the app can send data from phone to phone across distances between 200 to 500 feet, IBM Research staff member Nirmit Desai said. It doesn't add any more battery burden than an ordinary app, and the mesh network can be used without having to reconfigure the phone's network settings.It's a clever technique that's well suited to regions with subpar networks. But much of the promise of mesh networking remains unfulfilled.

The One Laptop Per Child (OLPC) effort to bring low-cost Linux-powered computers to developing nations tried using it to improve networking. Google Executive Chairman Eric Schmidt hopes mesh networking will help bypass government censorship. The ZigBee standard for home networking uses it, letting network data hop from one device to another across a home, but most folks haven't heard of it. Perhaps coming mesh features in future Bluetooth short-range networking will catch on.One of the biggest mesh challenges is achieving a critical mass of network nodes -- in this case, people with phones running the app."Having mesh as part of one of the most popular apps helps," Desai said. "The app and the mesh technology have great synergy. Each new download of the app results in availability of a new mesh node. And with each new mesh node, the app is able to relay critical information to more users."

And mesh networks can be used for more than broadcasting alerts. "Once we have a viable mesh, it can carry data for multiple applications, including messaging applications," he said.Mesh networks also open open up a new security concern. IBM's approach uses digital signatures to ensure information sent on the mesh network is from a trusted device and hadn't been modified.The Weather Channel is launching the app in emerging markets in Asia, Latin America and Africa. It's a very small app by modern standards -- just 3.2MB -- and is geared to work even on slow, older 2G networks still common in much of the world.That lower-resolution display (higher-resolution screens draw more power), however, helps Toshiba to achieve the long battery life, in combination with a power-efficient U series Haswell chip and the company's own BIOS.

The V634 weighs in at only 2.4 pounds -- placing it in the 11.6-inch MacBook Air weight class.Another model, the V834, is similar but comes with an ultra-high-resolution 2,560x1,440 touch display. That has a rated 14 hours of battery life.Manufacturers sometimes overstate battery life but even if Toshiba comes close to the claims of 22 hours and 14 hours, respectively, that's no mean feat.I thought I'd construct that dreadful sentence in honor of the concept that the one thing you should buy your lover for Valentine's Day is a drone.I've stumbled, you see, on the marketing page of Chinese drone maker DJI. This company believes that "every moment is a gift," one that should be captured by a camera drone.In order to emphasize this, DJI has peppered its site with, oh, red hearts and pictures of people thinking about kissing each other as part of its Valentine's Day campaign.

There's also this motivating thought: "Be curious. Get creative." Is this some twisted incitement to a new kind of love? I ought to be relieved there wasn't any reference to love being in the air.Perhaps the most moving (to tears) element of this marketing, though, is the limited edition Valentine's Day gift set.Well, there's a Phantom 3 Standard drone and a box of seven Ferrero Rocher chocolates. Yes, just like you'd see at your supermarket checkout counter retailing for a few groats. All this for a bargain $499 (£509 or AU$859).I contacted DJI to ask if this gift set really represented the apogee of romance. A company spokesman told me: "We were in no way trying to imply that a drone is the perfect Valentine's Day gift for everyone."He added that this offer was aimed at "creative people." Apparently, when it comes to a creative person's Valentine's Day, a drone "can be a pretty sweet way to show that you care about what matters to them -- and you love them enough to give them a new tool to pursue their passion."

Perhaps this is merely an extension of the human need to selfie itself to death. It's not enough to have handheld remembrances of hand-holding. You need the view from an eye in the sky.Looking back on the Super Bowl -- surely you remember it -- I can't help thinking too many brands didn't necessarily get it right by going all political.The American people have surely had enough of politics recently to make them prefer a root canal, given the choice.It's uplifting, then, to see Apple come along with an ad that reminds the viewer that people just want to live peacefully and have a good time. However their version of a good time rolls.Cupertino's latest iPhone 7 ad presents one night in the life of Planet Earth, as seen through the phones of users in 15 countries on six continents. Yes, there are a fair few selfies in there, but the whole thing shows a world that feels remarkably beautiful and free of rancor.What makes this ad at least a little out of the ordinary, though, is the music. In smaller, uglier hands, these images might have been accompanied by a cheery alternative ditty meant to make you feel so very, very happy.Instead, here we have mellow jazz to remind us that the mood we really seek most at night is one where we can stop thinking about what the world's powers have wrought or might think of wringing and let our minds wander aimlessly.

The world is a whimsical absurdity, often insensitive and even more often senseless.If at the end of each day, we find a little beauty, poetry and peace, we can rest in preparation for what the next day will bring.Does the Mac still matter? Apple execs tell why the MacBook Pro was over four years in the making, and why we should care.Not too long ago, Donald Trump insisted that, once he's president, he'll be "restrained" on Twitter.Instead, he appears to use the site in attempt to restrain others from doing things he doesn't like.On Wednesday morning, for example, he offered commentary on the San Francisco federal appeals court that's currently examining his executive order temporarily banning immigration from seven Muslim-majority countries."If the U.S. does not win this case as it so obviously should, we can never have the security and safety to which we are entitled. Politics!" he tweeted.Politics, indeed! The way it infiltrates our legal system, some might think, is reprehensible. For example, when one president or another attempts to appoint a Supreme Court justice of the president's personal bent.

Incidentally, the tech industry is keeping a close eye on the case. Silicon Valley heavyweights have voiced strong opposition to the ban and have even filed a legal brief against it. They worry it will inflict harm on their companies, which employ many immigrants.The president seems to want to use Twitter to pressure judges deciding the case. Last weekend, he referred to Judge James Robart -- the Seattle-based judge who ruled against his order -- as a "so-called judge."Some will surely detect a whiff of "do as I say or else."Moreover, there's an implication in Wednesday's tweet that the courts will somehow be responsible should a terror attack occur. This reflects another weekend Trump tweet, again targeting Robart, that read: "Just cannot believe a judge would put our country in such peril. If something happens blame him and court system. People pouring in. Bad!"The alleged badness, though, isn't confined to the courts system. Retailer Nordstrom has also taken a place in the president's axis of evil.

"My daughter Ivanka has been treated so unfairly by @Nordstrom. She is a great person -- always pushing me to do the right thing! Terrible!" tweeted the president.What has Nordstrom done to be not merely bad, but terrible? It's decided not to buy any of Ivanka Trump's fall collection, a decision some will see as political. Or, indeed, "Political!" The retailer insisted this was a business decision because the previous collection wasn't selling well."Over the past year, and particularly in the last half of 2016, sales of the brand have steadily declined to the point where it didn't make good business sense for us to continue with the line for now," said Nordstrom in a statement. "We've had a great relationship with the Ivanka Trump team. We've had open conversations with them over the past year to share what we've seen and Ivanka was personally informed of our decision in early January."The company's share price dropped briefly before recovering.

One can imagine that presidents in the past attempted to influence courts in a slightly more cloak-and-dagger manner. Some might find it heartening, therefore, that the president chooses to express his needs openly.Apple last month slimmed down its MacBook Pro lineup and added a dynamic Touch Bar to the keyboard, ridding itself of the function keys and allowing for more creative keyboard functionality. We generally liked the result of the changes in our review, but according to a report by iFixit, they come at a cost.iFixit opened up Apple's 13-inch MacBook Pro with the Touch Bar, and found it harder to repair than ever, with few easily replaceable parts. Hopefully, you won't want to swap out your battery or upgrade your MacBook's memory -- both are soldered or glued in place.Strangely, iFixit also discovered the speaker grilles on the laptop are ornamental -- the speakers themselves don't actually line up with them but project sound through the side air vents.There are some really great tablets out there, but a lot of them suffer from expensive starting prices. Pricing usually declines to a reasonable point, but only after those models are no longer shiny and new. If you don't want to wait, or don't have to, here are the tablets that offer a high-end experience for a premium price.
