Dim Laptop LED Screen – F1 or F8 Fuse just below the motherboard video connector | NWA PC Help

For those looking for assistance on finding the fuse on Various models, Please provide photos near the LCD Connecter, but also near where the power charger plugs in. I am seeing the possibility that some fuses may be located over near that area.
________________________________________________________________________________
This applies to Dell, Sony and many other manufacturers of laptops with LED based screens.

These issues are also commonly search on as no backlight.  In most cases when you know the screen is good, it will be a power issue from the motherboard causing the backlight to fail to power up.

On the motherboard you should find a fuse labeled f1 in the case of dells, that is approximately .8 mm in depth, and 1.55 to 1.6mm in length. This fuse protects the voltage circuit to the led’s. in the case of a dell inspiron 1545, it is a 3 amp, 32v fuse, that can be replaced relatively cheaply. Make sure tho that you have isolated the cause of the fuse blowing. Good luck!

The Fuse is located on the Dell Inspiron‘s just below where the led video cable connects to the motherboard.
Use a Continuity Tester or Multimeter to confirm whether or not it has blown.  If you find any other fuses or different locations, feel free to comment, or even link to pictures of other fuse locations and I’ll approve them.

For other manufacturer’s the location is not so obvious unfortunately.

Cut the cord and leave cable TV behind

The FCC’s most recent report on the cost of cable found that the price of expanded basic cable service increased by 5.1 percent [PDF] in 2012, and additional reports show that those prices have continued to rise, unabated, ever since.

Millions of consumers are now cutting the cord that provides television services while keeping the one that provides broadband internet. The idea: Replace traditional broadcasting with video streaming and downloading services so you can access the same television programs you love via the web.

Streaming Services

The centerpiece of this strategy usually begins with leveraging streaming services likeNetflix, Amazon Prime Instant Video, and Hulu Plus, many of which provide subscribers with recently-broadcast television programming, complete seasons of past TV episodes, and multi-device compatibility so you can watch on TV, your computer, or via a mobile phone or tablet. Each service tends to have specific strengths – Hulu is more focused on current television shows, while Netflix has the best movie selection. Also, many of these services offer programs that aren’t available on other services – including original programming that isn’t available on cable TV at all – so serious cord-cutters often find they need to subscribe to a multitude of streaming systems to watch everything they want to see.

Remember that an old-school antenna is always another option. With a powerful digital antenna, network programming is free (and much higher in quality than you probably remember from the old days). Newer high-tech services, including Sling TV, Roku’s product line, and the Google Chromecast, are all options that can give you access to streaming content to help you eliminate the cable company as the bloated middleman.

Video Download Services

If you’re the kind of person that collects programs – especially movies – for repeated watching, it often makes sense not just to stream video, but to download it for the long term. Programming stored on your own hard drive isn’t dependent on having a fast, uncongested to keep it going, so it can be watched even if the cable goes offline – and once you download it, it never disappears. (Streaming service contracts are generally time-limited, so a movie available on Netflix today may no longer be streamable tomorrow.)

Video content – either movies or individual episodes of television programs – can be downloaded from several services, including iTunes, Amazon Instant Video, and Google Play. Movies can be stored on individual devices, but these can eat up a huge amount of space on a storage-strapped smartphone, particularly if the movie is encoded at HD quality. A better idea: Store movies on a NAS device that every (authorized) device in the house can access. A QNAP Turbo NAS like the TS-453 Pro can work perfectly as acentral media server for all your downloaded content – and it can also do additional jobs like storing (and streaming) your downloaded music files, home videos, and other computer files.

Accessing centrally stored video is becoming easier than ever. Smartphones and tablets will require a service-specific app, and apps like QNAP’s Qvideo or Qfile make it easy to stream video directly from your NAS. Both Qvideo and Qfile stream video stored on your QNAP NAS directly to your phones or tablets, as well as streaming directly to Chromecast devices attached to a TV, or Apple TV via Airplay. Qfile can even sync media among computers on your LAN to back up and synchronize media on all your devices.

With all these options available and more on the horizon, more and more people are discovering that there’s no reason to shell out big bucks each month for the cable company’s rising prices and poor service. Cut the cord, and leverage streaming services and downloaded video to access the movies and television programming you want, when you want it.

AdwCleaner – One-Click Malware and Toolbar Removal – Technibble

AdwCleaner – One-Click Malware and Toolbar Removalby Husayn JamalAdwCleaner is a small, portable and freeware program that can easily remove stubborn toolbars and other malware from your client’s computer. As a technician, you may have encountered a client with an endless sea of browser toolbars and add-ons that they never used or even meant to install, but came with that latest update to Java or some other software. AdwCleaner allows you to remove these toolbars and other hidden malware in a single click.In some cases, antivirus programs, third-party uninstallers, or maybe even the built-in Add/Remove Programs feature can remove these pesky toolbars and other bloatware, but when they can’t, AdwCleaner’s one-click scan becomes very useful. The scan took about 40 seconds to complete on my Windows 8 Virtual Machine, and was able to completely remove the Ask.com and Conduit toolbars from Internet Explorer and Google Chrome.After launching AdwCleaner, click “Scan” and the program will search your client’s computer for any toolbars or malware that may reside there. After the scan has completed, it will display a log showing files, shortcuts, registry entries, and more. You can then de-select which items should not be removed and click “Clean” which will instantly remove the selected files. Alternatively, you could try using AdwCleaner’s Uninstall option first.Beyond what is described above, AdwCleaner does not have any extra features, but it is a very accurate and specialized tool for the removal of potentially unwanted programs and toolbars. One thing worth mentioning is that from the Tools menu, you can view the quarantine and download a separate program called “Hosts Anti-PUP/Adware” which will limit your client’s ability to download toolbars and other potentially unwanted programs again as it will block access to certain websites. This program can always be uninstalled at a later time if required.

Google Makes Up 25% of Internet Traffic

Google makes up 25% of Internet traffic

Google accounts for a quarter of all American Internet traffic and is growing faster than the Internet itself.

Americans do a lot of Googling.
Google (GOOG, Fortune 500) accounts for nearly a quarter of Internet traffic in North America, according to a recent study conducted by analytics firm DeepField. That makes Google’s Internet presence bigger than Facebook (FB), Netflix (NFLX) and Twitter’s combined, according to the report. During a few hours of each day, Netflix will eat up more bandwidth than Google, but the streaming video site’s peak traffic occurs just during “prime-time” hours — Google still averages a larger chunk of Internet traffic during the entire day.

The most stunning revelation from the survey is that Google is growing faster than the Internet as a whole. In 2010, Google represented just 6% of Internet traffic.
That’s because the study found 60% of all Internet-connected devices interact with Google servers during the course of an average day, including some gadgets you wouldn’t think would be talking to Google, such as game consoles and home media devices.
A big part of Google’s massive Internet presence and alarming growth comes from mobile devices. The company commands the largest chunk of the smartphone and tablet markets with its Android devices, and those devices all regularly check in with Google for updates throughout the day. Smartphone runner-up Apple’s (AAPL, Fortune 500) default search engine is Google, which adds to Google’s Internet traffic share.

YouTube’s data-heavy videos also play a role in Google’s large internet share, DeepField said.

Google Street View climbs Mt. Fuji
Google’s expanded internet presence has required the company to constantly build out its server capacity to handle the influx of traffic. The company has been spending more than $1 billion each quarter over the past few years on infrastructure investments.
“While it is old news that Google is big, the sheer scale and dominance of Google in the Internet infrastructure has significant implications on network design and evolution,” Deepfield’s Craig Labovitz wrote.
Google spokeswoman Liz Markman noted that its server improvements allow Google content and services to better reach consumers and deliver data-heavy streams such as YouTube videos more efficiently. The company had no comment on the DeepField study.
The DeepField report is based on a large cross-section of Internet traffic, collected from North American Internet providers. It covers roughly one-fifth of Internet traffic throughout the region, and Deepfield believes it to be the largest ongoing study of its kind.

Master the command line: how to use man pages | Macworld

Master the command line: how to use man pages

Master the command line: how to use man pages | Macworld

If you’ve read Macworld for any length of time—particularly our OS X Hints blog or any other story that asks you to use Terminal—you may have wondered to yourself: How do you learn about all those mysterious commands, such as ls or cd? Is it some kind of arcane knowledge, handed down only to initiates after grueling initiations? Well, no. Actually, anyone can learn about Terminal commands, if they know where to look. Today, I’ll tell you where.

Man up
The key to Terminal wisdom is the man command. It summons manual (or man) pages for almost any command; they’re the equivalent of a help system for the command line. In fact, man itself is a command, whose role is to format and display this documentation.

If you type man pwd, for example, Terminal will display the man page for the pwd command.

The beginning of the man page for the pwd command.
All man pages have a common format. They begin with name (the name of the command) and a brief description of what it does. The pwd command I looked at above shows the following:

pwd—return working directory name

Next comes synopsis, which shows the command any any options, or flags, that you can use with it. For pwd, there are two options: -L and -P. These options are explained in the description section:

DESCRIPTION
The pwd utility writes the absolute pathname of the current working directory to the standard output.

Some shells may provide a builtin pwd command which is similar or identical to this utility. Consult the builtin(1) manual page.

The options are as follows:

-L Display the logical current working directory.
-P Display the physical current working directory (all symbolic links resolved).

If no options are specified, the -L option is assumed.
As you can see here, each of the two options is explained, and a final sentence tells you that the command assumes that the -L option is desired if no other option (and there’s only one) is specified.

As you work from the command line, you’ll find that reading up on the options available for different commands is really important. You’ll learn the myriad ways you can use these tools, and some man pages also contain examples to help you understand them.

Paging man pages
When you look at a man page, you do so in Terminal through another command, called a pager; by default, this is the less command. What a pager does is allow you to view content in Terminal page by page, or line by line. When you’re viewing a man page, you will most often not see the entire page at once. You’ll need to page down to see more.

There are two ways to do this with less. If you press Return, the page will move down one line. And if you press the spacebar, the page will scroll one page (the number of lines visible in your Terminal window). You can tell that there’s more to come by the : (colon) visible at the bottom of the window.

Try it on your Mac: Open Terminal, type man ls, then press Return. The ls command’s man page is quite long, and you’ll need to press the spacebar several times to get to the bottom.

Sometimes, when you’re viewing a man page, you need to go back up and look at something that’s no longer visible. Depending on your Terminal settings, you may be able to scroll the Terminal window. If not, press Control-B to go back a page, and the spacebar, or Control-F, to go forward a page.

When you get to the end of a man page, you’ll see this: (END). You’ll notice that you can’t do anything at that point; you need to quit the less command; do this by pressing the q key.

Other ways to read man pages
If you don’t want to read man pages in Terminal, there are other ways to view this content. Carl Lindberg’s free ManOpen is a simple app that lets you view man pages in a more attractive way than in Terminal. Press Command-O, enter the name of a command, and click Open. ManOpen is especially useful because you can choose specific sections to view from a popup menu, and you can navigate more easily than in Terminal with the less command.

ManOpen lets you view man pages in a friendlier interface than Terminal.
But you can also find man pages on the Web. Just type man and the name of a command into your favorite search engine, and you’ll get plenty of hits. Apple has a documentation repository with man pages here. You can click Alphabetic Index to get a list of all commands, then search for the one you want. Apple’s man pages are useful because a popup menu near the top of the page lets you choose an OS X version, so if you need to see the man page for an older version of OS X, you can do so.

No matter which route you choose, man pages open the door to a goldmine of information about the command line. Use them and you’ll learn all the ins and outs of the commands you use.

Will iOS 7 make my old iPhone like new?

Will iOS 7 make my old iPhone like new?
CNET ‘s Marguerite Reardon offers some insight on whether  Apple’s  revamped  iOS  operating system will breathe new life into your old  iPhone .

Apple has given the operating system for its  iPhones ,  iPads , and  iPod Touches  a new look with the introduction of iOS 7. But is the software alone enough to satisfy eager Apple fans who are constantly looking to upgrade to the next generation of iPhone?

In this edition of Ask Maggie I take a look at some of the new features available in the software. And I explain how the iOS 7 could make older iPhones feel like new. Ultimately, I offer my opinion on whether users should upgrade to the next version of iPhone hardware or just upgrade the software and enjoy the benefits of new features and a new user interface.

iOS 7 offers a new look and feel for old iPhones

Dear Maggie,

I’ve had several iPhones through the years. I’m usually tempted to buy a new one each time they come out. Last year, I bought an iPhone 5, even though I already had the  iPhone 4S . I do like the bigger screen and the fact that the phone has LTE. But other than that, nothing much has changed in terms of the hardware on Apple devices.

Now I’m wondering if you think it will be worth upgrading when the next iPhone is introduced later this year. I’m just thinking that the new iOS 7 looks pretty cool, and I may not even need a new iPhone if I can update my iPhone 5 with the new software. What do you think? Will iOS 7 make me feel like I have a new phone?

Thanks,
Jerry

Dear Jerry,

It’s hard to answer your question definitively given that a new iPhone hasn’t yet been announced. At this point, I don’t know what new hardware features Apple will add to the next version of the iPhone, which we expect to be introduced in the fall. Still, I think what you’re getting at in this question is a valid point.

Eventually, the hardware differences among new devices become somewhat insignificant to most wireless users. Some people might argue that we’ve already reached that point. And that’s why the nearly 3-year-old  iPhone 4 , and almost 2-year-old iPhone 4S are still selling like hotcakes.

For me, the big leap in hardware came with the iPhone 5. While it looked very similar to the iPhone 4S, except for a slightly bigger screen and body, the most important technology change was its support of 4G LTE.

The iPhone 5 is the first iPhone to support this network technology. And in my opinion this hardware difference, which greatly improves network performance of the device, was enough to recommend the iPhone 5 over the iPhone 4 and the iPhone 4S.

I don’t anticipate the same kind of must-have hardware upgrade in the next iPhone. Of course, I expect the processor to be faster, the screen to be better, and the camera to be improved. But in my estimation those are all incremental changes that often don’t mean much to average consumers when compared with the previous-generation product. I think we’ve already reached the point where most consumers are fine with the hardware specs of last year’s iPhone, or any smartphone for that matter. We are now in an era where the big differences are about software features and the user interface.

Luckily for you and other iPhone customers who have bought older iPhones, the new iOS 7 will add a new look and feel, plus new functionality to your existing device. Even the 3-year-old iPhone 4 will get this refresh with the software update…
