Microsoft has shed light on the touchscreen gesture technology

Microsoft has shed light on the touchscreen gesture technology that will be implemented in Windows 8, including the hardware requirements that will be necessary for a consistent experience across multiple devices. The company notes that Windows 8 will run on the hardware currently on the Acer as07b31 Battery market, however upcoming touchscreen PCs built specifically for Windows 8 will be required to integrate five-finger digitizers.

The “fundamental gestures”, which were previewed earlier this year at Microsoft’s Build conference, will require no more than two fingers. Such gestures provide basic control over interface actions, panning, selection, zoom, rotation, and app or system commands.

Although only two fingers are necessary for core functions, Microsoft admits that two-finger gestures “can be very limiting” for certain applications. To avoid potential limitations, Windows 8 hardware will enable developers to take advantage of five-finger gestures for application input.

“The reason we went in this direction is a response to developer feedback,” Microsoft managers wrote in a blog post. “Developers do not want their creativity to be limited, and in particular, they let us know that they want to be free to use whichever multi-finger gestures or controls are useful.”

The company has also outlined several specific areas in which older Acer aspire 5520 battery hardware may prove inconsistent. Certain touchscreens on Windows 7 PCs are said to have problems registering individual taps, swipe to select, swipe and slide gestures, and swiping from the edge.

“We can overcome some of these issues with updated drivers, but this is entirely up to the hardware partners to evaluate and support,” the company adds.

Facebook Acquired 750 Patents from IBM

Facebook has reportedly acquired patents from IBM, a move that could help it shore up defenses against new patent infringement lawsuits ahead of its IPO.

The social networking company confirmed the purchase, and said the patents cover software and networking technologies, The New York Times reported on Thursday. Facebook did not disclose how much it paid for the patents or the patent numbers. Bloomberg reported earlier in the day, citing an unnamed source, that Facebook acquired 750 patents from IBM.

ipo market Facebook Acquired 750 Patents from IBM

Just last week Yahoo accused Facebook of infringing ten of its patents, in a lawsuit filed in California. Yahoo may have hoped that Facebook would settle quickly, experts said, in order to remove an uncertainty that could negatively impact Dell vostro 1700 Battery its public offering. Since Facebook hasn’t named the IBM patents, it’s unclear if they would help the company in any settlement negotiations.

The company did not immediately respond to a request for comment.

IBM is one of the biggest patent holders in the U.S. For the 19th year running, in 2011 it won the most patents among IT companies. But it has been offloading patents too. Google last year acquired over 1,000 patents from IBM.

Relative newcomers to the technology Acer batbl50l6 battery industry, Google and Facebook lag behind older companies like IBM, Microsoft and even Yahoo in terms of a patent portfolio. In an increasingly litigious environment, that makes Facebook an easy target for patent infringement suits.

The TF201 Fits into this Dock’s Rotating Hinge

Like its predecessor, the Transformer TF101, the Asus Eee Pad Transformer Prime TF201 tablet is named for its ability to plug into a keyboard dock accessory and become a laptop-like device. Since the Transformer Prime TF201 Mobile Docking Station ($150 as of March 7, 2012) is similar to the original Transformer TF101 dock in many ways, my impressions of the two docks are similar.

Just as with the original Transformer dock, the TF201 fits into this dock’s rotating hinge, connecting through a 40-pin dock connector. You slide a release latch to secure the slate. Here, however, I encountered the same problem as I did with the original dock: Despite the various pieces holding the tablet in place, it still had room to wobble, most notably when I folded it down over the Hp 510 Battery keyboard.

116526386 The TF201 Fits into this Docks Rotating Hinge

This keyboard dock adds 1.2 pounds and just 0.4 inch to the Transformer Prime. Unlike the original Transformer–which bulks up to the size of an average netbook with its dock–the Transformer Prime remains under an inch thick at only 0.75 inch with its dock attached. And you can still take it off when you don’t need it, leaving you with a very slim and sleek tablet. When it’s time to return to your business reports, you simply plug the keyboard back in. The whole thing folds together neatly, too, a design advantage for when you’re transporting the keyboard/tablet combo or pulling it out of your bag for your journey through airport security, for instance.

Another major advantage of the laptop-like hinge: Since it holds the tablet up, you don’t need to invest in separate stands or folding cases. And the hinge rotates down as you lift the tablet “open,” which raises the keyboard to a nice angle for typing, and produces a surprisingly well-balanced result. Usually a setup like this, with all the “guts” in the screen, becomes top-heavy and easy to tip over, but the Transformer Prime stayed firmly in place, even as I pushed it back a good ways.

Regrettably, as on the original Transformer dock, typing on the Transformer Prime dock is a mixed bag. Just like the keys on the TF101 dock, as well as on Asus netbooks, the island-style keys here are small and cramped. They’re functional, but they aren’t as comfortable to type on next to those of the Lenovo ThinkPad Tablet Keyboard Folio Case; I had to do a lot more shifting of my hands to accommodate the Toshiba pa3534u-1brs battery spacing. You could get accustomed to the feel over time, but it isn’t comfortable from the start. (I have to note, though, that a colleague with similarly small hands had fewer issues adapting, so your experience may vary.) I also found an alarming amount of flex in the keyboard deck, something I didn’t expect judging from the solid metal build of the rest of the device.

On the positive side, the feedback is good, neither too mushy nor too springy. Once you get used to the spacing, typing on this dock could be described as workable. When you consider the good-enough typing along with all the other benefits of this keyboard dock, you can see that it’s a valuable add-on for the Asus Eee Pad Transformer Prime TF201.

Development and Production of Large Format Lithium-ion Batteries

Lithium Technology Corporation (LTC) yesterday unveiled a retrofitted Toyota Prius, with plug-in capabilities allowing for 125+ miles per gallon fuel efficiency, which is powered by the Company’s unique battery technology. The battery for the Prius utilizes LTC’s new product line of lithium iron phosphate (LiFePO4) cells, the largest cells of their kind in the world, which are considered to be the technology of choice for car manufacturers.

New IPad has Hit the Shelves of Stores Around the World

Now that the new iPad has hit the shelves of stores around the world, equipped as it is with a Retina display, it’s going to have a frustrating effect on otherwise happy owners of the original iPad or the iPad 2 – and that’s not just blind envy of those who bought the shiny new version.

As we’ve previously reported, the 2048×1536 pixel resolution on the new iPad’s Retina display means that developers will have to submit updates to their apps that feature ‘@2x’ graphics. With a quadrupled pixel count, they’ll look great on the 2012 iPad, but all those extra pixels mean greater storage compaq 484170-001 battery requirements on your iPad. The result? You’ll be able to fit fewer apps on your iPad.

Now, if you have a new iPad, at least that reduced app number is counteracted by the fact that the ones you do have will look beautiful in their higher resolution. If you’ve got an original iPad or iPad 2, you’ll be using a load of extra storage space for high-resolution graphic you’ll never get the benefit of.
Developers need to update their apps to support the new iPad – their apps just won’t be competitive without that boost in resolution when rival apps look so much better on a 2012 iPad.

120305 New iPad 660 New IPad has Hit the Shelves of Stores Around the World

Apple has already approved a bunch app updates with improved resolution – indeed, the update list on my iPad 2 just now inspired this post; app after app with ‘Support for Retina display’ as the main improvement. Well, that’s just dandy for new iPad owners, but for the rest of us, our iPads suddenly have a lot less potential storage.

Last week, our own Matthew Panzarino reported that apps could almost double in download size thanks to the Retina graphics – that’s why the 3G download limit was increased to 50MB. I struggle with storage space on my 16GB iPad 2 as it is, trying to balance apps with TV shows and other content. Is it fair that I have to fill some of that hp 484170-001 battery space up with graphics I’ll never get the benefit of? Shouldn’t Apple intelligently serve a version of an app that’s optimized for my device (and yes, I’ll admit that’s easier said than done)?

I didn’t really want to upgrade just for a better display, but as the Retina updates to my favorite apps continue to roll in, suddenly a 32GB or 64GB new iPad feels that little bit more appealing.

A Regular Contributor to Ars Technica

Timothy B. Lee, a regular contributor to Ars Technica and an adjunct scholar at the Cato Institute, has joined forces with Christina Mulligan, a postdoctoral resident fellow at the Information Society Project at Yale Law School, to research a key problem posed by software patents: the cost of finding out that they exist. This op-ed distills their most recent research paper. The views expressed here do not necessarily represent those of Acer as07b31 Battery Ars Technica.

Nathan Myhrvold, the Microsoft veteran who founded the patent-trolling giant Intellectual Ventures, loves to complain about the “culture of intentionally infringing patents” in the software industry. “You have a set of people who are used to getting something for free,” he told Business Week in 2006.

Myhrvold is right that patent infringement is rampant among software firms. But in demanding that this infringement stop, Myhrvold isn’t just declaring war on what he regards as Silicon Valley’s patent-hostile culture. He’s declaring war on the laws of mathematics. The legal research required for all software-producing firms to stop infringing patents would cost more than the entire revenue of the software industry. Even if firms were willing to pay the bill, there simply aren’t enough patent lawyers to do the work. Firms infringe software patents because they don’t have any other choice.

If a real estate developer wants to build on a particular piece of land, she first must figure out who owns the land before she can negotiate a contract and start construction. Most of the time, this is easy. The landowner can be readily identified in a public records office.

ARS thrivebackcover A Regular Contributor to Ars Technica

In principle, a software developer starting a new project faces a similar problem. He needs to know if the software he is planning to create will accidentally infringe on anyone’s patents. But whereas looking up who holds claims to a particular piece of land is easy, finding out who, if anyone, holds patents related to a particular piece of software is difficult and expensive. It’s so difficult, in fact, that the vast majority of Acer aspire 5520 battery
software developers don’t even try.

Why is software different from real estate? In a new paper, we argue the fundamental difference is a matter of scalability: how much effort it takes to discover who owns an invention—or a piece of land—as the number of patents or land parcels increases. Property rights in land scale well because parcels exist in relatively well-defined locations on a two-dimensional plane. County officials take advantage of this fact to store records in a predictable order (or, more recently, to build databases searchable by geographical location). Geographical locations serve as an “index” for real property claims, so record-keepers can find any specific file quickly no matter how many files there are.

Some patents are similarly “indexable.” Chemical patents, for example, can be organized by chemical formula. Indeed, a German organization called FIZ Karlsruhe offers an electronic database called STN which allows researchers to look up patents based on their chemical formula. The existence of products like STN is one reason patent litigation is much less common for chemical patents than for software patents.

Unfortunately, software patents don’t scale well. It doesn’t seem possible to create an STN-like database for software patents. There’s nothing analogous to geographical coordinates or a chemical formula to uniquely identify software inventions. It’s hard to predict which aspects of a software product someone might try to patent. It’s even harder to predict which terms a patent lawyer might use to describe these concepts. So searching by keywords is likely to uncover only a fraction of relevant patents.

This means the only foolproof way to find all the patents that cover a particular computer program is by “brute force”—to pay a patent lawyer to sift through every software patent, one at a time, looking for ones that might be relevant. There are hundreds of thousands of software patents, with 40,000 new ones released every year. A single firm could easily spend hundreds of thousands of dollars on patent research for a single software Acer aspire 6935g battery
product.
Everyone’s problem

Who needs to worry about infringing software patents? The Green Bay Packers, OfficeMax, Kraft Foods, Aeropostale, and Oprah Winfrey’s Harpo productions have all faced software patent lawsuits. Indeed, virtually every medium and large firm in the United States performs activities—like maintaining a public website, using a computerized point-of-sale system, or using an Internet-based invoicing system—likely to infringe some software patents. So all of these firms are part of the software industry, at least as far as patent law is concerned.

In our paper, we estimate it would take at least 2,000,000 patent attorneys, working full time, to consider whether all these software-producing firms have infringed any of the software patents issued in a typical year. Even if firms wanted to hire that many attorneys, they couldn’t; there are only 40,000 registered patent attorneys and agents in the United States.

So Myhrvold is wrong to suggest firms should ignore software patents because they’re trying to “get something for free.” They ignore software patents because it’s mathematically impossible for them to do anything else. The patent system simply doesn’t scale up to an industry as complex and decentralized as the software industry. And if it’s practically impossible for firms to avoid infringing software patents, it’s unfair to punish them for their failure.

Milliamp LTD, the parent company of the popular website, ipodjuice.com, announced they have added 4th Generation iPod nano LCD screen replacements to their catalog of valuable Dell precision m65 battery services. Their most notable maintenance and upkeep functions are iPod repairs, iPod battery replacements, and provide the expertise needed to repair iphone devices.

ipod classic 5th battery replace repairzoom iPod Battery Provide the Expertise Needed to Repair iphone Devices Milliamp LTD is one of the most reputable iPod repair companies on the internet. Their stellar record in customer service is undisputable. In business for four years now, the company has ascended to the top by providing an almost unequaled quality of service since its inception.

The ease of the website, as well as the promptness and superiority of their repairs is unrivaled; as thousands of customers can testify. As founder of the website, ipodjuice.com, Mr. Anthony Magnabosco, explained, “We strive to bring our best to each customer because we understand they are the ones that make our company strong and successful.

While the 4th Generation iPod nano LCD screens are relatively durable, dropping the iPod can have a catastrophic effect on the outer glass screen. A direct impact at a certain angle can cause a real problem with the window.

The replacement screen offered by Milliamp LTD can be considered a bargain due to the quality and required precision of the work. Cautiously dislodging the broken screen in order to replace it with a new one is a long and delicate process because of the degree of deconstruction involved. It takes a great deal of Hp pavilion dv7 battery care and skill. The outer glass on the 4th generation iPod nano, interestingly, is completely separate from the underlying display. It is the outer glass that needs to be replaced in most cases, and not the display. This is why Milliamp LTD offers both kinds of repairs. If both components are damaged (which is a rare event), the company takes it into consideration when pricing out the repair.

It is possible for a user to replace his or her own screen, however it is not recommended. In addition to the difficulty in finding quality parts, the process can be quite complicated and one wrong move (such as a slip of the screwdriver) could ultimately damage the iPod nano beyond repair. The process of reconstruction also has to be taken into consideration. Each item must be returned to its exact place. Why take the risk of damaging or not being able to reassemble the iPod? It’s an unnecessary risk and it is strongly advised that you send your device to the experts.

“We don’t ever want any mishaps, so we make certain our technicians are highly-trained and knowledgeable in the iPod repair business.”, stated Mr. Magnabosco. nike ipod battery iPod Battery Provide the Expertise Needed to Repair iphone Devices

Top 10 Tips on How to Extent the Battery Life

Tagclouds :Battery,Acer as07b41 Battery, Acer as07b51 battery,Acer as07b42 battery,Battery Life

Anyone who’s used an iPhone for even a few days has discovered that while these phones are more powerful, and more fun, than perhaps any other cell or smart phone, one place they don’t excel is Acer as07b41 Battery life. Any halfway intensive iPhone user will recharge their phone almost every couple of days.

There are ways to conserve iPhone battery life, but many of them involve turning off services and features, which makes it a choice between all the cool things that the iPhone can do and having enough juice to do them.

Here are 14 tips to help you extend your iPhone battery life.

1. Turn on Auto-Brightness

auto brightness Top 10 Tips on How to Extent the Battery Life

The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it (when there’s more ambient light, the screen needs less power to be visible). Turn Auto-Brightnesson and you’ll save battery because your screen will need to use less power in bright places.

2. Reduce Screen Brightness

brightness slider Top 10 Tips on How to Extent the Battery Life

You can control the default brightness of your iPhone screen with this slider. Needless to say, the brighter the default setting for the screen, the more battery it requires. Keep the screen dimmer to conserve more of your battery.

3. Turn Bluetooth Off

bluetooth slider Top 10 Tips on How to Extent the Battery Life

Bluetooth wireless networking is especially useful for cell phone users with wireless headsets or earpieces. But transmitting data wirelessly takes battery and leaving Bluetooth on to accept incoming data at all times requires even more juice. Turn off Bluetooth except when you’re using it to squeeze more juice from your battery.

4. Turn Off 3G

turn off 3g Top 10 Tips on How to Extent the Battery Life

The iPhone 3G and later models can take advantage the speedy 3Gcellular phone network. Not surprisingly, using 3G requires more battery life to get the quicker data speeds and higher-quality calls. It’s tough to go slower, but if you need more battery, turn off 3G and just use the older, slower EDGE network. Your battery will last longer (though you’ll need it when you’re downloading websites more slowly!).

5. Keep Wi-Fi Off

wifi Top 10 Tips on How to Extent the Battery Life

The other kind of high-speed network that the iPhone can connect to is Wi-Fi. Wi-Fi is even faster than 3G, though it’s only available where there’s a hotspot (not virtually everywhere like 3G). Keeping Wi-Fi turned on at all times in hopes that an open hotspot will appear is a sure way to drain your Acer as07b51 battery life. So, unless you’re using it right this second, keep Wi-Fi turned off.

6. Turn Off Location Services

location services Top 10 Tips on How to Extent the Battery Life

One of the coolest features of the iPhone is its built-in GPS. This allows your phone to know where you are and give you exact driving directions, give that information to apps that help you find restaurants, and more. But, like any service that sends data over a network, it needs battery power to work. If you’re not using Location Services, and don’t plan to right away, turn them off and save some power.

7. Turn Data Push Off

data push Top 10 Tips on How to Extent the Battery Life

The iPhone can be set to automatically suck email and other data down to it or, for some kinds of accounts, have data pushed out to it whenever new data becomes available. You’re probably realized by now that accessing wireless networks costs you battery life, so turning data push off, and thus reducing the number of times your phone connects to the network, will extend your battery’s life. With push off, you’ll need to set your email to check periodically or do it manually (see the next tip for more on this).

8. Fetch Email Less Often

fetch data Top 10 Tips on How to Extent the Battery Life

The less often your phone accesses a network, the less battery it uses. Save battery life by setting your phone to check your email accounts less often. Try checking every hour or, if you’re really serious about saving Acer as07b42 battery, manually. Manual checks means you’ll never have email waiting for you on your phone, but you’ll also stave off the red battery icon.

9. Auto-Lock Sooner

auto lock Top 10 Tips on How to Extent the Battery Life

You can set your iPhone to automatically go to sleep – a feature known as Auto-Lock - after a certain amount of time. The sooner it sleeps, the less power is used to run the screen or other services. Try setting Auto-Lock to 1 or 2 minutes.

10. Turn off Equalizer

EQ Top 10 Tips on How to Extent the Battery Life

The iPod app on the iPhone has an Equalizer feature that can adjust music to increase bass, decrease treble, etc. Because these adjustments are made on the fly, they require extra battery. Turn the equalizer off to conserve battery. This means you’ll have a slightly modified listening experience – the battery savings might not be worht it to true audiophiles – but for those hoarding battery power, it’s a good deal.

Dealing with tech support is a hit-or-miss proposition. That’s because tech reps are typically under heavy pressure to keep call times short whether they provide real help or not. So why not save some time and money by troubleshooting common laptop issues yourself? We asked some of the biggest notebook makers, including Acer, Dell, and Lenovo, the most common user questions. We then boiled down the list to the top issues and provided our own easy fixes.

Master Your Touchpad

Following Apple’s lead, most notebook trackpads now support multitouch gestures for manipulating documents, web pages, and photos. Still, many users don’t understand the full capabilities of their laptop. Also, after installing an external mouse, settings for the internal touchpad and its buttons may be altered or even disabled by accident. Here’s how to find out what your touchpad can do and make sure it’s working smoothly.

On a Windows laptop, navigate to the Start button > Control Panel > View by Category. Then select Hardware and Sound. From there, click Mouse under Devices and Printers. This will open the mouse properties window, which should display a tab for your input device’s settings. For example, our Lenovo Ideapad V470 listed properties for its Elan Smartpad, though you may find other devices here, such as a Synaptics touchpad.

Clicking Options will let you confirm that the touchpad is operating properly and enable control over various features such as scrolling, multi-finger tapping, and mouse buttons. Tutorials on how to use these functions are usually found in this area as well.

Reinstall Your Laptop’s Software

Most modern laptops now come with plenty of extra software designed specifically for that system. These programs include applets controlling Wi-Fi and Bluetooth radios, onboard audio and volume, and screen brightness and power management utilities. In the course of everyday use, it’s possible to accidentally remove or corrupt these tools by installing new software or even just through innocent tinkering. If this happens, an easy fix could be a few mouse clicks away.

First, identify the problem. For example, find out if it’s the Bluetooth feature that no longer works, or perhaps it’s the power management software that has disappeared. In the case of Bluetooth, usually this ability is activated by pressing a function key at the top of the keyboard. The fix may be a simple matter of turning the Bluetooth radio back on. If that ability is no longer present, you might have to download and re-install your laptop’s Bluetooth software directly from the manufacturer’s website.

In the event that this option isn’t available, track down the maker of the component in question and download the firmware from the company’s web page. Looking up our Lenovo Ideapad V470 on Lenovo’s site revealed that its Bluetooth radio is made by Broadcom. Lenovo provides model-specific Broadcomm software for download, but users can also access software directly through Broadcom’s site. If the worst-case scenario comes to pass and one or more of your laptop’s function keys no longer operate properly, performing a full factory reset may be necessary.

Deal with a Dead Laptop Screen

LENOVO broken screen sh 8 Easy Fixes , DIY Laptop Tech By Batteryfast.co.uk One of the most dreaded laptop mishaps is a faulty LCD screen. Not only does this sort of damage render a portable potentially unusable, manufacturers typically will only repair laptop screens if the damage is considered to be a defect.

Be warned: Broken displays resulting from an accidental drop, impact, exposure to water, or electrical overload are generally not covered. But if your laptop’s screen suffers from a mass of bad pixels or more severe physical failures through no fault of your own, chances are the manufacturer will fix it.

To determine if your faulty screen qualifies for repair, diagnosis of the notebook is generally required using either onboard software or assessment from a tech support rep over the phone.

In the event of a serious system failure needing physical repair, the standard limited warranties for major manufacturers (such as Dell) usually allow for customers to send their machines back to a company repair facility. Under Dell’s standard warranty, a replacement laptop will be sent back to the customer the next business day along with shipping material to return the defective unit. Keep in mind that shipping times vary depending on availability of replacement parts, and manufacturers are not responsible for lost data contained on the faulty machine if returned. The whole process can take as long as 10 to 14 days, or perhaps longer if the requested part is out of stock and slow ground shipping is used.

Some users decide to avoid the hassle and uncertainty of mailing in their laptop altogether and attempt to repair it themselves. This is a solution best tried only when the laptop’s warranty has expired, because tinkering with a display will void existing coverage plans. Adventurous souls, however, can purchase replacement screens through sites such as www.screentekinc.com for about $100. The site provides helpful instructional hardware repair guides.

Recover from Complete Windows Failure

Don’t fret if your OS simply refuses to boot. Many laptop manufacturers pre-load their portables with a recovery partition on the hard drive. The partition is designed to load the version of Windows installed at the factory plus all bundled software in an emergency. Hitting one of your laptop’s function keys during bootup typically launches this feature. For instance, tapping F11 on Lenovo Thinkpads will activate Lenovo’s Recovery Program, while F12 does so on Dell machines.

Be advised that taking this route will wipe the laptop’s hard drive, resulting in lost data. Fortunately, these recovery tools also offer ways to repair the current installation of Windows, letting you avoid erasing your hard drive’s contents unless absolutely necessary. Another way to repair Windows is to boot the laptop from a Windows system repair disc (CD) which you can create ahead of time. In Windows 7, click Start > Control Panel, then select System and Maintenance, and Backup and Restore. On the left side of the screen you should see the option to create a system repair disc. You may have to insert your Windows installation disc during this process.

Quiet a Noisy Fan

diy tech skype sh1 8 Easy Fixes , DIY Laptop Tech By Batteryfast.co.uk Sometimes a laptop’s cooling system kicks into overdrive, causing it to create excessive fan noise and push hot exhaust out of its vents. The main reason a notebook’s fan spins up is that the system detects high internal temperatures and is attempting to cool things down. To kill the din, first make sure your laptop has adequate ventilation by clearing space around it on all sides. Physical obstructions such as books, papers, pillows, and other clutter may be restricting air flow by blocking vents. Soft surfaces with padding and fabric or dirt and dust particles could also be clogging circulation. You may find that relocation to a flat, hard surface—plus a few squirts from a can of compressed air—does wonders.

If these factors are not the issue and you hear distracting fan whir during basic computing tasks, your laptop could be unnecessarily dialed up for maximum performance. Try adjusting the Windows power plans withing the Control Panel. First click the Start button > Control Panel > Hardware and Sound, and next click on Power Options. Here you can choose a more efficient power plan (anything other than High Performance).

Solving Sound Issues

You may not give your laptop’s sound settings much thought—until audio becomes an issue. The notebook makers we spoke to explained that users often run into trouble with communication software. Skype and other similar applications can use any of a notebook’s installed audio devices. By default, a laptop will rely on its internal sound system to control its speakers and microphone. Connecting a wired headset to your notebook is simple; it’s just a matter of plugging the cords into the laptop’s microphone and headphone jacks.

Setting up Skype for use with a wireless Bluetooth headset is a little more complex but still not difficult. First turn your laptop’s Bluetooth radio on and use Windows to connect to the headset. To do this, hit Start > Control Panel > Hardware and Devices, then click Bluetooth Devices. Once the laptop and headset are paired and linked, open Skype and navigate to the Tools menu > Options > Audio Settings. Within this window you’ll see sections for Microphone and Speakers along with buttons for choosing an associated audio device. Make sure to select your headset from each of these pull-down menus.

One big advantage of HDMI is that it supports simultaneous transmission of video and audio signals to a TV or larger monitor. However, sometimes to properly output sound it’s necessary to manually enable HDMI as your notebook’s audio device from within the Windows Control Panel. Under Hardware Devices click Manage Audio Devices. Next, beneath the Playback tab, the HDMI audio device should be listed and selected as default. If HDMI is not listed, try unplugging, waiting a moment, and reconnecting the HDMI cable (with HDTV powered).

Let One Wi-Fi Software Rule

With passwords, signal strength, and network names to contend with, using Wi-Fi can be tricky enough without any performance hiccups. If that wasn’t enough, sometimes the Windows built-in Wi-Fi manager clashes with other software bundled with your laptop. Older versions of Windows, such as XP and Vista, provided a handy setting in the Control Panel for disabling or enabling the built-in Wi-Fi manager. Unfortunately, Windows 7 lacks this feature and automatically takes control of installed wireless adapters, making conflict with third-party applications more likely.

If you find that two programs are fighting over your Wi-Fi connection, the solution is easy. Instead of taking the radical step of removing third-party software completely, just open the bundled Wi-Fi application and delete any network profiles or names that are listed. Do the same in Windows by clicking Start > Control Panel > Network and Internet, then enter Network and Sharing Center. Under Manage Wireless Networks, place the cursor over a network name, right-click, and select Remove Network. After all network profiles are removed, reboot the laptop. From now on, create profiles and network settings only from within the software you plan on using.

Protect Your Battery

How long you first charge a latop’s battery no longer has any bearing on its performance. That said, there are definite physical conditions that affect overall battery life. Chief among them is temperature, and heat is the enemy. Though Lithium Ion cells have a comparatively high operating temperature (212 to 302 degrees Fahrenheit) as opposed to NiCd (95 to 134 degrees), their capacity degrades at a faster rate when exposed to heat.

Ideally, store unused laptop batteries in a cold, dry environment to prolong their life. Leaving a laptop plugged into an AC outlet for extended periods poses a risk to batteries because of heat exposure. One way to avoid this threat is to remove your battery when your system is plugged in for long stretches.

A more sensible approach is to unplug your notebook once in a while, which cools things down and helps push the battery toward its recommended storage charge of 40 percent. At full charge, batteries degrade the swiftest. Be careful, though, because depleting Lithium Ion cells completely increases the likelihood of battery failure.
