    Check manufacturing date: Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.

    Avoid frequent full discharges: Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Avoid frequent full discharges because this puts additional strain on the battery.

    Calibration is important: Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.

    For prolonged storage: Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level. Consider removing the battery from a laptop when running on fixed power.

    Keep it cool: If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator.

    If you have a Macbook Air (or any other laptop, for that matter) with a solid-state drive, you can increase its battery life by forcing it to hibernate instead of sleep.

    Generally, Macs only hibernate (which means they store the existing system state to disk and then power off) when the battery is almost completely drained. At all other times, they sleep–meaning the system state is stored in RAM, and the machine goes into a low-power mode. Waking from sleep takes less time than restarting and restoring from hibernation.

    But having the machine go fully off instead of just to sleep really can improve battery life. And because solid state drives start up exceptionally fast, restoring from hibernation is quick (five or so seconds, in my experience) compared to restoring from a standard drive.

    There are several utilities available (such as Jinx’s Smart Sleep, which installs as a preference pane and is Snow Leopard compatible) that will cause your Mac to hibernate instead of merely sleeping. Remember that when you want your Mac to emerge from hibernation, you must press the power button, rather than tapping any key on the keyboard.

    What’s least energy efficient part of your laptop? The LCD, correct. What are your options? Stop using computers? I would if I could, believe me. Or, you could be a little adventurous and try to swap out the LCD with another, more energy efficient one. Sort of like hammering a nail with a sledgehammer, yes.

    The company that makes the replacement LCDs is called Pixel Qi, and it claims that its LCDs are anywhere between one-quarter to one-half as power-hungry as “normal” LCDs. Pixel Qi doesn’t explain how or why its LCDs are so much better than other ones. Let’s call it magic and leave it at that.

    The fancy LCDs should be available by the end of June.

    ProTip: when using a laptop and battery power is a concern, dim the screen all the way all the way down. Yeah, your screen is a little darker, but the battery will last a little bit longer. No harm in that.

    I remember a few years ago, mobile PC with mobility and a relatively low price is, indeed, had a fire, could well be “punched notebook and desktop kicking” trend. However, only about a year, with the continuous price cuts notebooks, mobile PC quickly attributed to silence, and now even the two markets are difficult to get their hands but disappeared. Contrast mobile PC and notebook, and its configuration can be done almost the same, but the only difference between the two lies in the battery. A small battery, so that notebook is unlimited prospects for the development; the lack of a small battery, mobile PC is going for a dead end. Can be seen that the importance of the battery has been unusual.

    As people demand more and more mobile, notebook sales surge in the past two years, and increasingly thin, easy to carry. However, the mobile office is not only required the lighter the better laptop, its battery life determines whether you can successfully complete its work. The popularity of Centrino technology, making the current mainstream notebook standby time has reached 3-4 hours or more, can basically meet the needs of a half-day work.
     

    If you are only the notebook as a desktop machine to use, then the battery may not be concerned about. But with the popularity of wireless Internet access, limiting computer also only the power cord, in which case, using battery-powered chances greatly enhanced. However, the rechargeable battery is not a once and for all, its life will be based on charge and discharge times to decide. Such as lithium batteries are now mainstream, about 300-500 times the depth to withstand charge and discharge, after which power will be rapidly depleted, until it can not be used. In the secondary market, the most criticism is the battery aging.
     

    Once the laptop loses battery, it becomes a mobile PC, worth plummeted, and inconvenient to use, I have a lot of close friends have been troubled by this problem. Under normal circumstances, the normal use of the laptop, in almost two years later have to face the battery problem, but at this time to ensure good notebook itself, configure enough to use. If the change sets a new, of course, huge waste; if left unchecked, but also their hearts quit. Well, the problem how to solve it? Currently we have four kinds of conventional ways to evoke the old books new life: purchasing a new battery; to buy compatible batteries; their replacement batteries; to buy an external lithium battery.
     

    However, speaking of these four methods have advantages and disadvantages, such as the original battery expensive; compatible battery quality can not be maintained; replacement batteries danger great; external lithium battery to bring inconvenience and so on.

    With all the crystal-ball-watching over the seemingly imminent Apple tablet, one issue hotly debated around the CNET offices, but infrequently mentioned elsewhere, is the hypothetical device’s status as a mobile computer.

    There are two schools of thought on this: either the Apple tablet (or iSlate, or whatever it ends up being called) will be a 10-or-so-inch tablet PC with a full Mac OS X operating system; or it will merely be a larger-screen version of the current iPod Touch, which has a closed, limited phone-like OS PA3284U-1BRS.

    The former would mean it could very likely run any software you’d run on a MacBook, from Firefox to Photoshop, and maybe even install Windows 7 via Boot Camp or Parallels. The later points to a hermetically sealed ecosystem, where apps would have to be approved and sold through an official app store (as in iTunes).

    Initially, at least, the scant evidence hinted at the Apple tablet being akin to a touch-screen, keyboardless version of the company’s current laptops. After all, convertible tablet laptops are, if not common, than at least easy to find. While mostly intended for medical, education, or other specialized markets, there are a handful of consumer-oriented ones, such as HP’s TouchSmart series.

    There is even already a tablet version of the 13-inch MacBook you can buy. It’s from a company called Axiotron, which takes apart stock MacBooks and rebuilds them as tablets, with a touch screen and stylus. We reviewed one a couple of years ago and found it to be an interesting, if expensive, alternative for tablet-loving Apple fans PA3285U-1BAS.

    The last several rounds of Apple tablet rumors, however, point more decisively towards an iPhone or iPod Touch style device. The Financial Times reports that Apple is planning a press event on January 26 in San Francisco, while the Silicon Alley Insider claims several app developers have been asked to prepare large-screen versions of their current iPhone apps.

    While the recent rumors all seem to point towards a device without a full PC-style operating system, the purported 10-inch screen of the Apple tablet may create a different set of psychological expectations from consumers. After all, that’s the size of most Netbook PCs, which, despite costing as little as $299, offer the same (or in some cases, the “Starter” versions of) Windows XP or Windows 7 as full-size laptops, and which can install and run virtually software (with the possible exception of power-hungry apps like 3D games and video editing suites).

    And, even with single-core Intel Atom CPUs, a 10-inch Netbook can run multiple apps at once–something currently not allowed (with a few exceptions) on the iPhone/iPod Touch platform.

    Oracle received unconditional regulatory approval this week from the European Commission for its acquisition of Sun Microsystems.

    Below is the all-hands memo Sun CEO Jonathan Schwartz sent to employees following the announcement on Thursday. Pay particular attention to the first letter of the first 7 paragraphs.
    Believe it or not, it’s been more than nine months since Oracle first announced their intent to acquire Sun in April, 2009. And the ‘interim’ period has been tough on everyone–on our employees, and our partners and customers. Thankfully, that interim period is coming to an end, with regulatory approval from the European Union issued today, and only a few hurdles remaining–before Oracle formally expands beyond software to become the world’s most important systems company Inspiron 3800 battery,Inspiron 4000 battery.

    Even though we’re not quite across the finish line, I wanted to leave you with a few final thoughts.

    All in all, it’s been an honor and privilege to work together. In my more than twenty years in the industry, the last thirteen at Sun, I’ve had a chance to work with and around an enormous diversity of companies, from every sector you can imagine. I can say with conviction that Sun’s people have always stood apart as the brightest, most passionate, and most inspiring. I’ve never had a bad day in my thirteen years for one very basic reason–I’ve always been surrounded by the best and brightest individuals I’ve ever come across. That’s been an honor and privilege, for which I’m enormously thankful.

    Technology from Sun, alongside our employees and partners, have changed the world. We’ve opened markets, elections and economies. We’ve helped build the world’s most important and valuable businesses. We’ve played a key role in discovering new drugs, in bringing education and healthcare to those in need, and supplying the world with an incredible spectrum of entertainment, from smartphones to social networking. I doubt any company has had such a significant influence over the way we see or experience the world. I once told Scott McNealy he was the Henry Ford of the technology industry, making remarkable innovations accessible to anyone, and creating an immense number of jobs around the globe for those that made use of them. I can’t begin to tell you how proud I am of my association with that cause and the people behind it, and the value we created for ourselves and those that exploited our innovations.

    I also know we’ve had more than our share of very tough challenges. Amidst the toughest market and customer situations imaginable, I’m proud we’ve always acted with integrity, with a sense for what’s right, and not simply what’s expedient. Over the years, I’ve heard time and again, from those inside and outside the company, “I like and I trust Sun.”

    Building that good will is something to which you’ve all contributed. And you have every right to be very proud of it.

    Make no mistake, it’s been an enormous asset.

    So, to the sales and SE teams across the world who continually give their all to bring the numbers home–thank you for the trust you’ve built with customers, and the results you’ve delivered. I hope you’re prepared to have the wind at your back, you deserve it.

    To the service professionals who every day build, maintain and run the world’s most important data centers–thank you for your excellence and discipline, 7?24.

    To the professionals who run the functions and processes that are the company’s spinal column–thank you, we’d be paralyzed without you.

    And lastly–to the engineers and marketers who’ve fostered a perpetual belief that innovation creates its own opportunity–thank you. You’re right. Innovation does create its own opportunity. Like Oracle, we’re an engineering company in our heart and soul, our potential together is limitless.

    Now many of you know that I came to Sun when a company I helped to found was acquired in 1996. I’ve also led, and been a part of many, many acquisitions at Sun, both large and small. From those experiences, I’ve learned one very clear lesson–the single most important driver of a successful acquisition are the people involved–and how committed they are to the new owner’s mission.

    And the most effective mechanism I’ve seen for driving that commitment begins with a simple, but emotionally difficult step.

    Upon change in control, every employee needs to emotionally resign from Sun. Go home, light a candle, and let go of the expectations and assumptions that defined Sun as a workplace. Honor and remember them, but let them go.

    For those that ultimately won’t become a part of Oracle, this will be the first step in a new adventure. Sun has a tremendous reputation across the planet, well beyond Silicon Valley. It’s a great brand to have on your resume. We’re known as self-starters, capable of ethically managing through complexity and change, for delivering when called upon, and for inventing and building the future. With the world economy stabilizing, I’m very confident you’ll land on your feet. You’re a talented, tenacious group, and there’s always opportunity for great people.

    For those that have roles at Oracle, may you start with a clean slate, ready to take on the myriad opportunities ahead. With the same passion and tenacity for Oracle’s success that you’ve had for Sun’s, and a renewed sense of energy around executing on a far broader mission. There is no doubt in my mind you, and Oracle, will be remarkably successful, beyond the market’s wildest expectations. But it’s important you come to work thinking, “Sun is a brand, Oracle’s my company.” Don’t look for ways to preserve or dwell in “how we used to do things.” Look for ways to help customers, grow the market, and improve Oracle’s performance.

    Sun is a brand, Oracle is your company.

    And to that end, with nine months of getting to know them, I’ve found Oracle to be truly remarkable, led by remarkable people. From Larry on down, they understand the enormity of the opportunity before them, and they’re more than prepared to execute on it–across the board. I’ve seen their commitment and focus, now they need yours. I’m confident you’ll give it the 10,000% effort it deserves–and we’ll all see the end result.

    So thank you, again, for the privilege and honor of working together. The internet’s made the world a far smaller place–so I’m sure we’ll be bumping into one another.

    The Apple laptop battery tablet rumors are going to keep coming until the company finally releases this thing. Tech bloggers, and now even the mainstream media, can’t help themselves from wondering what Apple will or won’t do with the forthcoming device, which is widely anticipated to be introduced at Apple’s media event scheduled for Wednesday.

    Here’s the latest roundup of speculation about the tablet.

    • The tablet will have a 3G connection, and there are two carriers being considered for it, says Fox News. Apple is in talks with AT&T and Verizon, but the details are still not finalized, according to sources within the Latitude D830 battery companies.

    • There will be not one, but two dock connectors on it. iLounge says that will allow the tablet to be docked/charged in either landscape or portrait orientation.

    • AppleInsider’s sources say the tablet will look exactly like an overgrown iPod Touch, down to the home button, volume toggle, and power button.

    • Add McGraw-Hill and Hachette Book Group to the list of publishers Apple Latitude X300 battery has approached about including their content on the tablet. It’s widely assumed that e-books, magazines, and newspapers will be a key part of Apple’s strategy for the device. It’s already been reported that HarperCollins, The New York Times, and Conde Nast have also been in talks on the same topic.

    Be sure to come back to CNET at 10 a.m. PT Wednesday, when we’ll be blogging the Apple event live.

  • 21Jan

    One week from today Apple laptop battery is hosting what has easily become its most anticipated event since the original iPhone.

    Here’s a summary of everything we know Apple will unveil for sure: nothing. With the exception of one thing: Apple is definitely hosting an event at one of its favorite locations, the Yerba Buena Center for the Arts in San Francisco at 10 a.m. on January 27.

    But it’s plenty of fun to do some educated guessing about what they’re cooking up down in Cupertino. And thanks to some well-placed leaks and a slow trickle of clues over the past year, it’s easy enough to predict what will be the main event: the much rumored, blogged, and wished for Apple 338794-001 ,361742-001 tablet device.

    But that leaves plenty of other questions. What will it be called? We don’t know. iSlate, iTablet, Tablet, iBook, iPad have all been tossed around. When will it ship? The Wall Street Journal said March, but an industry analyst is now saying maybe June. Like most Apple events nothing is for sure until Steve Jobs announces it from on stage. And though Apple runs a pretty tight-lipped organization, things have a way of trickling out right before their major announcements. So even though Apple hasn’t confirmed anything yet, here are some pretty safe bets as for what to expect next week.

    Multimedia
    The tablet, in theory, will fall somewhere between a MacBook and an iPod Touch. So what do you do with it to make it stand out as a device you’d need in addition to one or both of those? A large-screen device with no physical keyboard certainly isn’t going to be for making phone calls or word processing. The easiest assumption is that video and music will be two of the most important applications at the center of the tablet’s purpose. In regards to music, there’s been some speculation that the tablet is the reason Apple developed iTunes LP in the first place. It’s a more in-depth multimedia experience for full albums, and while it works on a laptop or PC, it would appear to be a better fit for a touch-screen device with a large screen, which is what a tablet will be.

    As my colleague Donald Bell points out, it could be interesting to see how or if the LaLa.com acquisition comes into play with the tablet. Using Lala’s own music-scanning tool, the new iTunes feature would figure out what’s already in your music collection, upload whatever is not in its library and let you stream music from Apple’s servers to any of your iTunes compatible wireless devices, such as the tablet.

    Video on the tablet could be far more interesting however. Apple has a wealth of content available via iTunes already that can play on an iPhone, iPod, computer, or Apple TV, so it would make sense that another device with or connected to a screen would be added into the mix of stuff with access to iTunes. But there’s also been talk for a while of a subscription service for, say, TV shows on iTunes.

    Digital books, magazines, and newspapers
    The other fairly obvious application for a device that’s expected to be somewhere around 10 inches is an e-reader. Everyone’s doing one these days, after all, and many people are buying them. Sure, Jobs was famously quoted for saying that “people don’t read anymore.” But it was obviously an exaggeration, and Apple A1008A1012A1022 is known for bashing product categories before joining them, and he said something far more revealing in a conversation in September.

    In discussing Amazon’s Kindle, Jobs was blunt in saying that dedicated devices had a limited appeal. But he added that “general-purpose devices will win the day.” Apple already sells e-books via the App Store, so it wouldn’t be a stretch to see them on this upcoming device, especially since a 10-inch device is a much more natural fit for reading text than on an iPhone.

    More intriguing is what Apple could have lined up with magazine and newspaper content. There have been multiple reports of Apple approaching book, newspaper, and magazine publishers about their content. We don’t now exactly how this would work–subscription? exclusive content?–but it’s safe to bet that the tablet won’t be just an oversize video and music player with a Wi-Fi connection.

    Gaming
    Apple has apparently sent invitations for the event to gaming publications, which could indicate a couple things about the nature of next week’s event. First, that games will be a part of the tablet in some way. Video games are a huge seller via the App Store, and it’s reasonable that what works well on a small touch-screen could be even more appealing on a screen three times larger.

    Second, it could be because they’re going to have a lot of demos related to stuff in iPhone OS 4.0. Apple has intentionally highlighted games and game developers at iPhone and iPod Touch related events for the past few years.

    iPhone OS update
    This is usually the time of year that Apple introduces the updated version of its iPhone software. That gives developers some time to play around with it and come up with apps for launch around the same time as the yearly iPhone hardware refresh in June or July. It’s been assumed that the latest iPhone OS would be modified so it would scale up for a larger screen, i.e. the upcoming tablet. If that is the case, it would certainly make sense to announce both at the same event.

    Steve Jobs
    Jobs has been back in the saddle since July officially, and there was some question whether he’d be at the last public event. But he did show up at the iPod unveiling, which served as his public homecoming of sorts.

    You can bet that Jobs will be the ringleader on January 27, clad in his usual garb of black turtleneck, jeans, and white tennis shoes. The tablet is the first new device category from Apple since the iPhone in 2007, and the word is that this project has been his personal mission for a long while. Expect him to be the emcee as usually, but with a cast of special guests as he has done with past events: bringing up chosen developers for demos of applications, or the head of the project.

    This is basically what we can expect at the event next week. Nothing has been confirmed other than there is an event taking place–which we’ll be live blogging so you can get all the details as they happen. Details also have a way of leaking out ahead of these things, so stay tuned over the next week for all the latest juicy rumors.

    Apple laptop battery on Tuesday released Security Update 2010-001, a collection of fixes for users of Mac OS X Leopard (10.5) and Snow Leopard (10.6).

    As with most security releases, the latest Mac OS X update fixes issues within the core system and does not add new features to built-in applications or fix application bugs.

    Security Update 2010-001 fixes an issue in Mac OS X’s CoreAudio where a maliciously crafted MP4 audio file could be used as a way to execute code or terminate an application on the user’s D5318,HD438 computer. Image RAW’s handling of DNG files has also been updated to avoid what Apple calls “arbitrary code execution.”

    The Flash Player plug-in has been updated to version 10.0.42 fixing multiple vulnerabilities, including code execution on the user’s computer. Adobe issued an update for this in early December, but Apple has included it with this release.

    Additional changes in other system level components like ImageIO, CUPS and OpenSSL provide further security for Mac OS X users.

    Security Update 2010-001 is available through the software update mechanism in Mac OS X.

    In addition to updating Mac OS X, Apple also released an update for users of its Boot Camp software. According to notes provided with the update, Boot Camp 3.1 “adds support for Microsoft Windows 7 (Home Premium, Professional, and Ultimate).”

    The update also fixes a couple of bugs with the trackpad, turns off the digital audio LED when not in use, and adds support for wireless keyboards and the Apple KD186,GD761 Magic Mouse.

    Boot Camp allows users to create a partition on a Mac and install Windows. Unlike virtualization apps like Parallels or VMware Fusion, Boot Camp users must restart their computers to use Windows.
