Add Facebook Questions To Brand Page





Facebook released a new version of Questions late last week and will soon begin to roll the feature out to Facebook Pages as well.



The feature can be used by brands and publishers as a new way to survey customers or crowdsource information from readers.



Page owners can ask questions with a set of possible answers, and they have the option to allow users to add additional answers for which other users can vote. The best part is users can share the questions for their friends to answer, broadening the potential exposure.



But, if you want to get your hands on the feature for your Facebook Page today, you can add it by following the simple steps below. Note: The feature is not yet available in all countries.






1. Sign In To Your Facebook Page




Go to the “Account” tab at the upper-right side of your Facebook account and click “Use Facebook as Page.” Click “Switch” next to the page you’d like to be signed into (this should be the page you want to add Questions to).










2. Go To Facebook’s Questions Page




Go to Facebook’s Questions page, which not only outlines the product, but is also where you add Questions to your Page. Once you’re there, click on the bright green button that says, “Get Questions Now.”



The action will apply to the Page you’re logged in as, so if you’d like to add Questions to multiple Pages, repeat step one and two for the specific Page in question.










3. Ask Your First Question




After you’ve clicked “Get Questions Now,” a pop-up box will open confirming that Questions have been added to your Page. You’ll now see the Questions tab on your Facebook Page and you’re ready to ask your first question. You can add poll options and the ability for your fans and others to add other answers. The question will post to your wall as well as the News Feed of users who have “liked” your Page.



It’s as simple as that. Any questions?







Top 10 reasons why delaying the iPhone 5

Apple’s usual summer iPhone jamboree, which in the past two years has tied with its WWDC conference, looks all set to be pushed back until September. Insiders claim that the showcase will focus solely on iOS 5 and Mac OS X Lion, with the iPhone 5 instead being unleashed at the Cupertino company’s September press event, usually reserved for iPod updates. Here’s our Top 10 reasons why pushing the iPhone back makes sense.



1 Build hype over the summer



Apple’s acutely aware of the power of the rumour mill. iPhone 5 teases and leaks have already been swirling around the web for months, but by holding back on its release by just a few short months it can be sure that tech watchers and battery bloggers will work themselves into a frenzy. And that’ll feed into plenty of mainstream media coverage too.



2 Tie in with the release of iOS 5



ios 5



iOS 5 is set to be touted at WWDC this year, rather than at a dedicated event in April, as was the case in 2009 and 2010 with iOS 3 and iOS 4. There’s no point revealing it and then releasing a phone using the old iOS 4 software. It’s just not Apple’s way and is something it’s bashed BlackBerry and Nokia for in the past. iOS 5 and iPhone 5 will be unleashed at the same time.



3 Let Apple assess competition



Ice Cream Sandwich



Android Ice Cream is likely to be trailed heavily at this year’s Google I/O event in May. There’ll then be a slew of new phones using the OS unveiled over the summer. Apple will want to assess the new OS and new hardware. Plus, it won’t want any other phones to get in its way.



4 Unify releases iPhone releases with the iPad



ipad 2 promo



Take this with a hefty pinch of salt, but Apple is rumoured to be releasing yet another iPad in the autumn. If that is the case, it’ll have an unstoppable pair of gadgets if it releases the iPhone 5 at the same time.



5 Clear run to Christmas



BB Xmas branding



Christmas is a vital period for Apple. And while its last quarterly results proved that it motors whenever it releases products, unleashing the iPhone 5 just as the rush for gifts starts means it’ll be a must-have. A pared-down iPhone nano would be a best-seller too. Just imagine the sales figures.



6 Tie in with the new MobileMe



mobileme



The cloud-based MobileMe is said to be intrinsically linked to iOS 5 and is likely to be shoved out for public consumption in September. Putting the iPhone 5 out at the same time, perhaps with free subscriptions for new owners, will help it gain mindshare quickly and make the iPhone 5 even more desirable.



7 It’ll gazump IFA



ifa berlin logo



IFA is one of the tech industry’s biggest shows and kicks off in Berlin at the beginning of September every year. It’s where the Galaxy Tab was first seen last year and will doubtless be used to show off Apple-battling kit this year. An Apple event, touting the iPhone 5, would undermine much of the work by its main rivals.



8 Deflect from the iPod’s decline



ipod nano



The iPod is always updated in September. But the music device, while still selling big, is in decline. Putting out the iPhone 5 at the same time as some re-jigged iPods would help Apple move away from its original best-selling portable brand and show how the iPhone is now its leading light.



9 Get an antenna fix perfected



antennagate



There must be no antenna woes with the iPhone 5. By pushing the iPhone 5 back, Apple has plenty of time to test and trial the new handset and ensure that it doesn’t suffer from the same problems as its predecessor.



10 See how NFC and mobile wallets pan out



iPhone NFC



Google’s mobile wallet plans are gathering pace already. Near Field Communication (compaq 319411-001 battery ) tech is widely expected to be a part of the iPhone 5, but Apple will be watching closely to ensure the standard is unified and that it can be easily implemented before making a final call. A few months delay will definitely help in this case.

Top 28 iPad 2 Tips and Tricks

Master your new iPad 2 with these quick tips and convenient shortcuts



Your new iPad 2 might not be as full-featured (or as complicated) as a laptop or desktop PC, but a few neat tricks are still hidden between the surface. Read on to learn how to secure your iPad, sync your bookmarks, and more.



Download the free iPad User’s Guide: You may have noticed that your iPad didn’t come with a big printed manual–that’s not Apple’s style. However, you can download the PDF version of the iPad User’s Guide from Apple’s Web site, or you can read it in iBooks if you have that installed (iBooks is available as a free download in the App Store). Make sure to download the manual for iOS 4.3.



Take a free guided tour: Apple provides video tours for each of the preinstalled apps, so you can get a good look at how to use them.



Use the Side Switch: You can use that neat switch on the side either to enable and disable audio alerts (this doesn’t affect video/audio playback) or to lock the screen’s orientation in portrait or landscape mode. You can toggle which function is assigned to the side switch by opening Settings from the Home screen, selecting General, and choosing the function you want under the ‘Use Side Switch to’ heading.



Multitasking and audio controls on iPadMultitask in iOS: You probably already know that you can press the Home button twice to bring up a list of currently running or suspended apps. However, you can also swipe the multitasking bar left to right to quickly access audio/video playback controls, a shortcut to the iTunes app itself, and volume controls. Also, when you choose whether the Side Switch should mute alert sounds or lock the screen orientation (see the item above), the function you didn’t choose will appear in this shortcut bar.



Speed up your sentences: Double-tapping the spacebar while typing a message will type a period and then a space.



Don’t let AutoCorrect mess you up: If you don’t like the option AutoCorrect gives you, reject it by finishing the word as you prefer, and then tapping the suggestion. If you want to use AutoCorrect’s choice, just type a space or punctuation mark, or tap Return, the moment it pops up.



Secure your backups: You can encrypt your iPad’s backup data in iTunes. Just open the iPad in iTunes, click the Summary tab, and check Encrypt iPad backup under the Options heading.



Prevent automatic sync once: Sometimes you don’t want to sync your iPad when you connect it to your computer. In this case, hold down Shift-Control (or Command-Option, on a Mac) in iTunes while plugging your iPad in, and iTunes will skip the automatic sync just once. Alternatively, you can safely interrupt a sync by dragging the unlock slider while the iPad is midsync.



Toggle data roaming: If you’re using a 3G iPad, you can turn data roaming on in the Settings, Cellular Data menu in case you want to try receiving cellular Internet through a different provider (fees may apply Toshiba satellite pro a120 battery). You can also check your data usage by going to Settings, General, Usage.



iPad passcodeMake your passcode more complicated: iOS defaults to a four-number passcode, but you can turn it off by going to Settings, General, Passcode Lock, Simple Passcode. Now you can use any full keyboard password to lock the iPad. The password also helps to encrypt your mail and attachments on the iPad, so you probably want to make it safer than a four-digit number.



Set the iPad to self-destruct in 10 seconds: Okay, not really–but you can set the iPad to erase all data after ten failed passcode entry attempts by checking the Erase Data option under Settings, General, Passcode Lock.



Tweak AutoFill: You can choose to enable Safari’s AutoFill feature in Settings, Safari, AutoFill. From there, you can tell Safari to fill forms automatically either by using your specified contact information or by remembering the names and passwords you’ve entered while logging in to Websites in the past.



Sync your bookmarks: You can use iTunes to sync your iPad’s Safari bookmarks with your PC’s Web browser. Open the iPad tab in iTunes, click the Info tab, scroll down to the Other heading, check Sync bookmarks with, and choose your preferred browser.



E-mail photos: The easiest way to e-mail photos from an iPad is to open the Photos app, select a photo, press the button in the upper-right corner (the rectangle with the arrow, not the trash button), and choose Email photo… to send.



Web page links on iPadKnow your Web links: You can check a linked word’s actual destination URL by touching and holding down on the link–it’s a perfect way to sniff out phishy links.



Choose an app for e-mail attachments: You can open a file attached to an e-mail message by tapping the attachment in Mail, but if the default app isn’t the one you want to use, you can press and hold and wait for a menu that lets you select an app.



Use the iPad as a picture frame: Not for physical photographs, silly. You can press the Picture icon in the lower-right corner of the Lock screen to have the iPad display its available photos.



Traffic conditions on iPadShow traffic conditions: Open Maps, press the dog-eared page icon in the lower right, and then turn the Traffic overlay on. If your iPad has an Internet connection, Maps will show real-time traffic conditions in the displayed area. Green means traffic is going at the posted speed limit, yellow means traffic is slower than the posted speed limit, and red means traffic is stop-and-go.



Share podcasts with friends: Listening to a podcast that you think a friend would like? You can share the link while you’re listening to it by pressing the Email button while it’s open.



Don’t forget your downloads: You can immediately see if your iTunes account is due for any incoming downloads by opening iTunes on your PC, clicking the Store menu, and selecting Check for available downloads. This trick can come in handy if your download process is interrupted, or if you missed some bonus iTunes content that came with an album you purchased.



Turn on Universal Access: You can enable options such as closed-captioned movies, VoiceOver screen reading, zoom magnification, and inverted white-on-black text by selecting the iPad in iTunes, opening the Summary tab, and clicking Configure Universal Access under the Options heading.



Forget Wi-Fi networks: So you accidentally connected to a network once, and your iPad remembers it for life–whether you like it or not. On your iPad, go to Settings, Wi-Fi, and find the network under the ‘Choose a Network’ heading. Tap the blue arrow next to the network you want to remove, and tap the button on the top that says Forget this Network.



Specify your Spotlight searches: The iPad uses Spotlight for its built-in search functions, and you can tweak it to your needs in Settings, General, Spotlight Search. If you have a lot of data on your iPad, for example, you can selectively disable search in different categories (Contacts, Applications, Audiobooks, Notes, laptop battery, Events, Mail, and so on) that you don’t use so that your desired results show up faster. You can also simply change the order in which the search-result categories display by dragging them up and down, so that your more frequently used search categories show up at the top of the page.



Restricting in-app purchases on iPadTurn off in-app purchases: Go to Settings, General, Restrictions and tap Enable Restrictions to selectively enable restrictions that apply to your apps, content, Game Center, and more. If you’re worried about other people breaking your bank account on in-app purchases, just disable In-App Purchases under the ‘Allowed Content’ setting.



Switch up the fetching frequency: Your iPad automatically grabs new data, such as incoming e-mail. However, the iPad periodically activates apps that don’t support iOS’s Push feature so that they can go “Fetch” new data–which uses the tablet’s battery life. You can tweak your Push and Fetch settings in Settings, Mail, Contacts, Calendars, Fetch New Data.



Change your e-mail signature: Don’t be one of those people who leave the default ‘Sent from my iPad’ signature on all their messages. Change it in Settings, Mail, Contacts, Calendars, Signature to…well, anything but that.



Swap the search engine: Too good for Google? You can change Safari’s default search engine by going to Settings, Safari, Search Engine. Alas, you can only choose from Google, Bing, or Yahoo–no bringing back AltaVista for you.



Take a screenshot of whatever is on the screen: Press Home and the sleep/wake button simultaneously. The screenshot will automatically appear among your photos.

Top 28 iPad 2 Tips and Tricks


How to charge and discharge battery





How to charge and discharge laptop batteries to extend battery life time



A laptop battery can be charged 300-1000 times. The actual number depends on the way it has been treated. In the last post of this series, I outlined the influence that the temperature has on a battery’s lifespan. Today, I will explain how a battery should be charged and discharged with care.



Fully discharge a new battery and then re-charge it. This calibrates the battery.



Calibrate the battery every 30 charges, i.e., fully discharge it and charge afterwards.



charge laptop batteryAvoid frequent full discharges. In contrast to NiCd (Nickel-cadmium) and NiMh (Nickel-metal hydride) batteries, Li-ion (Lithium-ion) batteries show no memory effect. That is, it will do no harm to the battery if it is re-charged before it is empty. Full discharges will strain the dell latitude d531 battery.



low-battery-levelAvoid total discharges. Total discharges, i.e., to the cut-off point, can destroy battery cells. Not all cells in a laptop have the same voltage. Your laptop’s battery gauge only displays the state of the whole battery. If a cell goes below a certain voltage it will be destroyed. Therefore, it is safer to stop working when your battery level reaches 20%. The low battery level can be configured under Vista in the advanced power settings applet. Vista will warn you when the battery reaches the low battery level.



maximum-processor-stateAvoid high discharge rates. High discharge rates also strain the battery. Therefore, I would avoid power intensive tasks while working on battery. Some laptops come with special power management software that can disable unused components. Every piece of hardware that is active produces heat and wastes precious battery capacity. I also recommend checking out Vista’s advanced power management features. You will find many ways to reduce the power consumption. For example, I always set the maximum processor state to 1% while working on battery. You will be surprised at what a modern CPU can accomplish with 1% of its capacity.



Avoid full charges. Fully charged batteries deteriorate faster, especially at high temperatures. Monitor the dell latitude d531 battery icon in the systray and disable charging before it is fully charged. I guess this is not really a practical advice. Hence, it is only something for Dell vostro 1520 battery life-saver enthusiasts.



Dell-disabling-charging Avoid charging. This might sound like a rather unrealizable piece of advice because an empty battery has to be charged so it can be used again. The problem is that a lithium-ion laptop battery only allows a limited number of discharge/charge cycles. If you are working on main, Windows will try to charge the battery whenever it falls below a certain level. This procedure is the worst thing that can happen to a Toshiba Pa3534u-1bas battery. Usually, power management is set to high performance while the laptop is connected to AC adapter. This increases the heat in the laptop while the batteries are being charged. One option is to disable charging while working on main. A far better option is to remove the HP probook 4310s Battery if you don’t need it for the next couple of days.

Did you know that you can stream movies from your PC to the iPad, use it as a secondary monitor, connect USB speakers and keyboards, and browse Websites with actual tabs? Here’s how to get the most from Apple’s iPad.



The iPad is loaded with all kinds of features you’ve probably heard about, but look a little deeper, and its extra abilities might surprise you. Some of these secrets are enabled through apps, while some are built into the device already.



Turn Your iPad into a Secondary Desktop Display

With its big, high-resolution display, it’s a shame to just park an iPad when switching to a computer. Instead, Air Display ($10) makes your iPad a second screen for your Mac, extending the desktop. The tool has just been submitted to the App Store and should be released soon; I checked out a beta.

The first reviews of the iPad 2 have emerged, declaring Apple’s new touchscreen tablet as even farther ahead of its competitors than the original iPad, though some reviewers were disappointed with the image quality of the device’s new front- and rear-facing cameras.



The iPad 2 sports several new evolutionary enhancements both inside and outside. On the outside, the tablet is thinner, has a flat back with tapered edges and a front-facing VGA camera and a rear-facing HD camera. Internally, Apple has upgraded the original A4 processor to a dual-core A5 chip with significantly faster graphics.



The device goes on sale on March 11 at 5 p.m. and starts at $499 for the entry-level 16GB Wi-Fi version.

Breakdown and Analysis of iPad 2





Interestingly, Apple chose not utilize a live stream for this keynote, which might have given you reason to wonder just how big of an event they were considering the iPad 2 to be.



Nevertheless, there were plenty of opportunities to follow along via live bloggers. And now that we finally have word from Steve Jobs himself, how does the new iPad 2 compare to all the expectations and hype going into today’s event?  Let’s take a closer look at what was unveiled for the year of 2011, or the “Year of the iPad 2.”



Built for Speed



Apple led off with the most important hardware component found on any computer: the processor. With a custom dual core A5 processor (according to Apple, the first dual core to ship in volume), the iPad 2 claims to possess a twice as fast CPU, and will run 9x faster in terms of graphics. The best part—and this smartly was revealed early on—is that the iPad 2 will maintain the same battery life despite these improvements. This is indeed one of the understated strengths of the original iPad. You don’t have to hit to charger as often as you would expect.



Video and Gyro



As expected, the iPad 2 will ship with both front and rear video cameras, thus allowing for integration with FaceTime and for use with a new native app demonstrated later called Photo Booth.  The addition of a gyroscope opens up a lot of app development opportunities for tablets in the wild. With both of these hardware improvements, the iPad 2 will position itself more as an interactive device as opposed to a passive one from which consumers simply take content. This is in line with how the Web and Internet have evolved.



Thinner and Lighter



We knew the next generation iPad would be thinner and lighter. During the presentation, it was revealed that the iPad 2 will be 33% thinner (8.8 mm vs.13.4 mm). It was also a nice touch comparing the iPad 2 to the iPhone 4 with the new iPad registering in at 0.5 mm thinner than the phone. It was also a nice touch to use the metric system as comparing the sizes in millimeters produces a larger sounding difference as opposed to comparing in inches. The weights were still given in pounds, and it is worth noting that the 1.3 pound iPad 2 didn’t quite break the sub-1-pound mark.

Your Laptop Battery Shoud be Longer Runtime.

Is your laptop battery dead?

Is the runtime not long enough to get you through the day?

Do you carry one of those huge external battery packs?



This instructable is intended to show how one may replace the dead li-ion/li-poly cells of a laptop battery and how one may increase the capacity of the battery by adding extra cells.



The reason why adding extra cells to the internal battery is suggested compared to carrying around an external Dell inspiron 1525 battery pack is that for the same amount of cells in an external pack, the laptop can run significantly longer if those cells were used internally.



Step 1External battery pack? Rip it apart and never think of using an external pack again!



So what’s the voltage rating on your internal battery pack?

What’s the rating on your power brick?



Lets use my tablet computer as an example.







www.goodlaptopbattery.com .au  300x2251 Dual touch screen Acer laptop arriving in December by goodlaptopbattery.com.auQuality laptop battery shop: goodlaptopbattery.com.au



www.goodlaptopbattery.com.au – Australian leading laptop batteries, camcorder batteries, camera batteries, laptop ac adapters supplier. Specializes in laptop computer battery, notebook batteries, HP laptop batteries, Dell laptop batteries, Toshiba laptop batteries, Acer laptop batteries.



Factory-direct price, fast shipping and  100% Secure Shopping Guarantee!



The battery pack is rated for 3.7v * 3 cells or about 11volts. However, the power brick outputs 20v.



I’ve bought external battery packs before and have calculated how long it should last using watt hours instead of amp hours. However, that was wrong. The Dell latitude d620 battery pack would need to output 20v in order to power my tablet, thus the battery cells used to increase the voltage does not attribute to the amp hours, which is indicative of how long the battery pack should last. Thus, a difference of 9 volts is significant. That’s about 2 li-ion cells wasted just to match the voltage.



Another problem with using external packs is that the laptop would think that it’s connected to an outlet, thus is not so weary of watching how much power it drains. The power brick for my tablet outputs 2.5 amps, thus it is possible at times my tablet is drawing 2.5 amps from the external pack. However, the internal battery pack only requires an average of 1 amp per hour.



So what would one do in order to increase the runtime of one’s battery pack? Forget the external pack, just add more cells to the internal one.

Extend Your Laptop Battery Charge Life

In this instructable, you will learn how to extend the life of a laptop’s charge. If you are going to be flying or driving long distance, these steps can help make the battery last much longer then usual and make the ride a little less stressful.



There are many simple steps and some more complicated steps but in the end, I was able to achieve an 8 hour charge on my year old laptop. The results will vary for your laptop if you have an inefficient CPU or a high RPM hard drive the gain will be smaller, but generally you will gain more time out of one charge.



In some cases, following these steps can even extend the life of the battery. Which means savings of 100 dollars or more.



The laptop used in this instructable is a HP Pavilion DV5130ca



Specs:



2.0 GHz – AMD Turion 64

120 Gigabyte 4700 rpm

Broadcom 802.11b/g wireless adapter

128 mb ATI Rage Mobile

Windows XP MCE 2005



All other specifications are insignificant when configuring a PC for power management.

Well for those who don’t want to get into installing programs and buying a new battery, these are some simple things you can do to extend the life of a charge.



1. Reduce the brightness of your monitor to the lowest readable level.



The backlight in most laptops are like “mini-fluorescent” (cold cathode) bulbs. They will really drain your battery quickly.



2. Turn off your wifi when you do not need it.



The wifi card is another power hungry device. Think of this – when you make a call on your cell phone, the battery drains very quickly, but if you simply play games or listen to music, it can last a very long time. This is the same idea. The wifi card is “calling” the hotspot all of the time. Even if there isn’t a hotspot around, it is continuously looking for one.



3. Use windows primitive power management to control your CPU.



When unplugged from the wall, click on the battery in your task bar and click max battery. This will extend your laptop’s life because your CPU will be reduced to a slower speed. (continue reading for a better explanation of reducing your CPU’s speed as this makes a HUGE difference in the length of your high quality battery charge.)



4. Unplug unnecessary peripherals.



Unplug that USB light or your wireless mouse when you don’t need them. Although minor, these devices could give you those extra few minutes of charge.

Laptop Battery Types

Laptop Battery  Types



With the passage of year’s technology is also attaining new heights, bringing before the people the most sophisticated electronic gadgets, for the better performances in respective sectors. The laptops happen to be the latest gadget in this respect. However simple it may be in appearance and also composition, you have to apply lots of measures for its maintenance, and it’s most sensitive area is the battery.

There are indeed several types of laptop batteries that are essential for keeping a laptop running properly. In this regard, there are a number of ways to properly care and maintain a laptops main power source, the battery, since the batteries of laptop are constructed with a number of crucial components for regulating charge and power supply to the laptop.



What and how many types of notebook batteries are available in the market? Well there are many but if you are the consumer there is a need for you to check and also to know the ideal battery for your laptop. Now, in respect of the different types of batteries that come to our concern are the Nickel Cadmium (NiCd) Batteries, which are in reality were the first rechargeable batteries manufactured for laptops. Though inexpensive, and being of high output and versatility the have been abandoned by the laptop manufacturers with the introduction of several efficient and lighter-weight batteries.

The next that do come in the category are the Nickel Metal Hydride (NiMH) Batteries, which at the time of its commencement was regarded as big development concerning power output, reliability, cost, safety and capacity. It is to be noted, that it was the “memory effect” that was the only issue, which required them to be fully discharged before recharging to gain maximum output. However, with the up gradation of batteries, these older ones are found in the older model laptops. In this respect, the Lithium Ion (LiON) batteries happen to be the latest version, and ahs become the most popular for laptops. This device has been most successful since the elimination of “memory effect”, and also happens to be much lighter than the other two in weight. For this the market price is also the highest. But again, at the time of detecting the ideal one among the various types of batteries there is a need to be cautious of the battery cycle.



Apple Laptop Battery



It is known that one battery cycle is used every time when a battery is charged or discharged. Now, what is a battery cycle in reality? It technical terms, it is defined as the number of cycles a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. In addition, the lifetimes 500 to 1200 cycles are typical. Besides while buying try to have a prior knowledge of the run time of the batteries, which does depends on a great number of factors. In maximum segments, it is the design of, and the power demands made by the machine that determines the actual battery run-time.



For instance, the three factors of using the screen, the hard drive and other accessories do play a significant role to influence the duration of the run-time. There are also other types of batteries, known as Smart and Dumb Laptop Batteries. There are some laptop batteries, which are, equipped with internal microprocessor circuits and do play a considerable role in the management of battery energy, setting the charger to the correct charge algorithm, predict running time, or according to Smart Battery System (SBS) forum, provide a state-of-charge (SoC) indication. Theses are known as “Smart” batteries. On the contrary, those batteries that remain devoid of these features are known as the dumb ones, found to provide power only.
