How to test LCD screen inverter in a laptop
.

In this post I explain how I test the LCD screen inverter board in a laptop computer.
The screen inverter failure is very similar to the backlight lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light.
If you suspect the inverter board failure, I know only one reliable way to test that. It’s either replacing the inverter board with a known good one and see if it works, or connecting a known good backlight lamp and see if your presumably bad inverter lights it up.
In most cases I go with the second method - testing the laptop with a known good backlight lamp. Why? Because backlight lamps are pretty much universal. The same backlight lamp will work with many different inverters as long as they have matching connectors. I’ll talk about these connectors later.
The inverter board is located inside the display panel under the LCD screen. In most laptops you can access the inverter board if you remove the LCD screen bezel. The inverter board has connectors on both ends. The left side of the inverter is connected to the LCD cable. The right side of the inverter is connected to the backlight lamp which is mounted inside the LCD screen. Check out this display diagram.
So, the inverter is getting power from the motherboard, but the screen is still dark. Apparently, it’s either bad inverter or failed backlight. Let’s test it with a known good backlight.
Here’s what I’m going to do:
1. I will unplug the LCD screen from the right side of the inverter. Basically, I’m unplugging the LCD backligth lamp which is located inside the screen.2. I will plug in my known good backlight lamp which you can see on the picture below. Please notice that my test backlight lamp is shorter than the screen, but for the test purpose that’s OK.
Results I’m expecting:
1. If my test backlight lights up, the backlight lamp inside the screen is bad and there is nothing wrong with the inverter board. If that’s the case, you’ll have to replace the LCD screen or replace the backligth lamp (which is not easy at all).2. If my known good backlight lamp stays dark after I turn on the laptop, most likely we have a faulty inverter board. If that’s the case, you’ll have to replace the inverter board and it’s relatively easy.
There are two different types of backlight connectors, you can see them on the picture below. The top one (big) is not as common as the bottom one (small). I do most of my test with a backligth lamp which has a small connector.
IMPORTANT! If you decide to buy a new backlight lamp for test, you have to make sure that the connector on the lamp matches the connector on the inverter. Very often backligth lamps are sold without any wires attached. If you plan to use this backlight as a test equipment, you’ll have to find one with wires as I have on the picture 3.
You can buy a cheap backlight lamp with wires here.
Finally, when you ready to test the laptop, unplug the LCD screen from the right side of the inverter.
Plug in your test backlight lamp and turn on the laptop.
In my case, the backlight lamp lights up, so the inverter board works properly.

The right side of the inverter is connected to the backlight lamp which is mounted inside the LCD screen. Check out this display diagram.
To make sure that inverter board is getting power from the motherboard (via the LCD cable), you can test it with a multimeter. In my case I connected the “+” lead of the multimeter to the pin 1 on the connector and the “-” lead to the ground trace around the screw hole. I got about 19.4V DC on that side of the inverter, so it’s getting power from the motherboard.
WARNING! If you accidentally short something on the inverter while testing it, you can damage the inverter or even the motherboard. Proceed on your own risk! Not sure? Don’t do that!

Yes, it will run Crysis.
With Windows 7 now finished, Microsoft's next challenge is to drive adoption. Those with high performance PCs made for gaming will only switch if there is a decent incentive to do so. While the nice Aero effects and new taskbar are reason enough for some of us who spend most of our time working on our PCs, gamers will need a little bit more.
Microsoft's Games for Windows site lists the following seven reasons for a PC gamer to get Windows 7:
1 - Performance

While the nice Aero effects and new taskbar are reason enough for some of us who spend most of our time working on our PCs, gamers will need a little bit more.
Microsoft's Games for Windows site lists the following seven reasons for a PC gamer to get Windows 7:
1 - Performance
To quote a coworker: 'Across same hardware, Crysis runs awesome on Win7! Even better than XP!'. Code for the OS has been optimized for better all around performance for games. Whatever you're playing now should be a better experience in Windows 7.
2 - Compatibility
The top third-party games, services, and international versions of games have been tested in Windows 7, so you should not worry about Windows 7 breaking your games. Feel free to move to Windows 7 because whatever you're playing now should work fabulously in Windows 7.
3 - Discoverability
You can use Start -> Search to find any game you just downloaded or installed. No need to launch a separate application. Likewise, you won't need to launch a game to get more info about it: The Windows 7 Games Explorer can show you in-game statistics within a preview pane plus delivers up-to-date info about your favorite game publishers and gives you the opportunity to try new games.
4 - Easy updates
The new Games Explorer will notify you whenever updates are available for your games so you don't have to go searching for them yourself or have to launch the game to see if there's an update waiting.
5 - DirectX 11 support
DirectX 11 means better games, pure and simple, with more advanced features for games to use.
6 - Multitouch support
An increasing number of gamers are using multitouch devices. Windows 7 supports multitouch-capable machines, so you can buy the latest and greatest multitouch laptop or desktop confident it's going to work in Windows 7.
7 - Classics

Looking to save a buck while buying a laptop? If so, Wal-Mart will have you come calling with the $298 Compaq Presario 15.6-inch notebook (CQ60-419WM) when it goes on sale this Sunday, July 26. The low pricetag appears to be retaliation against Best Buy's laptop challenge that offers a 15-inch Acer laptop for $299 (already sold out).According to this Wal-Mart blog, the laptop features the AMD Sempron SI-42 CPU clocking in at 2.10 GHz, Nvidia's GeForce 8200M GPU, 3 GB of RAM, a 160 GB hard drive, a SuperMulti 8X DVD±R/RW with Double Layer support, and built-in 802.11b/g WLAN support. The laptop also comes pre-installed with Microsoft Windows Vista Home Basic (32-bit) and a 60-day trial of Norton Internet Security 2009."Quantities are limited and will begin selling at 8:00 AM on Sunday, July 26th," the blog stated. "May want to pass that along because we expect this one will be quite popular."
Source: Yahoo-Microsoft deal unlikely this week
Label: Computer Newsby Ina Fried
Microsoft and Yahoo may well reach some sort of search partnership, but any deal is unlikely to come this week, a source told CNET News.
The on-again, off-again talks reportedly heated up last week, with Microsoft executives said to have traveled to Yahoo. The All Things Digital Web site reported that things were "down to the short strokes."
Among those said to have made the Silicon Valley trip were three of Microsoft's top online executives: Yusuf Mehdi, Satya Nadella, and Qi Lu.
However, a deal has yet to materialize, and a source said on Thursday that none is likely this week.
The Wall Street Journal reported on Thursday that Yahoo's board plans to meet on Thursday for an "update" on the talks.
Yahoo CEO Carol Bartz said in May that she was open to a search deal if she believed in the partner's technology and they provided "boatloads" of money.
Microsoft CEO Steve Ballmer has indicated for more than a year now that he would like to strike some sort of search deal, although he no longer wants to acquire all of Yahoo as his company offered to do in February 2008.

PayPal tries rewiring e-commerce with new interface
Label: Computer Newsby Josh Lowensohn
PayPal, eBay's well established but aging mechanism for online payments, is trying to rebuild itself for a new generation of online commerce possibilities.
At an event for press and developers on Thursday, PayPal and its partners described several new programming interfaces that are part of the company's upcoming Adaptive Payments Service and showed what developers can do with them.
For example, Microsoft will use the interface to enable payments within its forthcoming Azure cloud-computing service. And LiveOps' on-demand outsourcing service will use it to automatically handle fluctuating payment amounts and changes to who's being paid. Finally, the interface takes PayPal beyond the browser, opening it up for use on mobile phones, set-top boxes, and other increasingly smart devices.
"It's truly disruptive," said PayPal CEO Scott Thompson at the event. "It puts developers in the driver's seat by allowing you to do what you want to do and (choose) how you want to get paid."
The new service will be available to 300 PayPal partners starting Thursday, with a public beta this November--just in time for PayPal X Innovate 2009, its first developer conference.
PayPal is pitching the Adaptive Payments platform to developers as a way to more easily build PayPal-powered payment options into their applications. It's also a more streamlined version of PayPal's existing program for letting businesses manage transactions between several different parties.
The new payments service is a key part in PayPal's plan to double its revenues within the next three years. Back in March, PayPal's president Scott Thompson promised as much, saying that by 2011, the company should be doing somewhere between $100-120 billion in annual payments. PayPal has also had a fire lit underneath it since Amazon rolled out its own online payments service around this time last year. It let users make online purchases using billing information that was stored on Amazon.com
PayPal isn't just central to eBay's future. It will eclipse the company's auction and commerce operations, the company says.
"PayPal is a business that will be bigger than eBay," eBay Chief Executive John Donahoe said Thursday at the Fortune Brainstorm conference.
PayPal is a force to be reckoned with. On average, more than $2,000 goes through PayPal every second of each day. It has 75 million active accounts, and it's available in 190 markets and 19 different currencies.

Beta testing
Before the announcement, PayPal had been working with a handful of companies to test the new APIs (application programming interfaces). One of those companies is Microsoft, which is tapping PayPal for online payments in the Web applications built for the company's upcoming Azure platform.
At the unveiling, Yousef Khalidi, a Microsoft distinguished engineer, demonstrated an application that integrated PayPal's payment and billing functionality. It took only two days to integrate it into the existing product, Khalidi said.
Khalidi said that Microsoft plans to offer a simple way to build PayPal's mechanism into hosted applications as part of Azure's full release later this year.
Microsoft probably had an easier time choosing PayPal for its payment service than some of the alternatives: Amazon Flexible Payment Services and Google Checkout both come from companies in direct competition with Microsoft's Azure cloud-computing service.
Michael Ivey, CEO and co-founder of TwitPay, also took the stage to show his company's use of the new PayPal API--specifically to let people pay multiple people at once.
"In one transaction, I'm paying four different people," he said. Before the new APIs, the service would require users to make each payment as its own transaction.
Sites already using the new API include: Webassist, GroupCard, Lottay, Rainfall of Envelopes, and MedPayOnline.com
"PayPal will help you get paid for your innovations--your business will become our business," Thompson told the developers. "We view you as our third set of customers."

"PayPal will help you get paid for your innovations--your business will become our business," Thompson told the developers. "We view you as our third set of customers."
New features
The new payment service has a handful of new features designed to make it easier for developers to make money with their applications and services.
Thompson said that even if developers were acting as an intermediary between the person sending the money and the recipient, they would now be able to take their cut of that transaction--just as PayPal does.
Part of getting that to happen involves a new API that lets developers create peer-to-peer and business-to-business money-sharing applications. They can now also split up payments into several transactions and let users authorize a payment after the transaction's been made. Those two mechanisms can speed purchasing, regardless of whether the buyer is ready to pay the full amount at the outset.
As part of the new platform, PayPal also is changing the way fees are charged. Application developers can choose to have the sender of the money, not just the recipient, pay the fee.
In addition, the fee rates can be changed based on the type of purchase, which should ease the chore of handling both high-value transactions and micropayments (transactions below $12) within the same application. As it stands today, PayPal currently requires sellers to have two different accounts open, one for bigger payments and another for micropayments--and each has different rates.
People use PayPal today through a Web interface, but a new API will bring PayPal to nontraditional computing platforms including mobile phones, set-top boxes, and gaming consoles. That's important, given that those devices increasingly are networked and have their own ecosystems of applications. And moving to a browser can be disruptive to a user who just wants to make a quick payment.
Using PayPal that way also means that a developer must build the necessary user interface, though. PayPal didn't provide specifics on that element of the new payments system.
Overall, Thompson said the new payment system will help PayPal keep pace with changes in technology and business.
"The pace of innovation is just staggering," he said. "And the next wave of innovation is poised to move that much faster. "

Label: Computer NewsVendor knew about critical vulnerability in December 2008, never fixed it, slates updates for late next week
By Gregg Keizer

Adobe Systems Inc. late Wednesday admitted its Flash and Reader software have a critical vulnerability and promised it would patch both next week.
One security researcher, however, said Adobe's own bug-tracking database shows that the company has known of the vulnerability for nearly seven months.
In a security advisory posted around 10 p.m. Eastern time Wednesday, Adobe acknowledged that earlier reports were on target. "A critical vulnerability exists in the current versions of Flash Player (v9.0.159.0 and v10.0.22.87) for Windows, Macintosh and Linux operating systems, and the authplay.dll component that ships with Adobe Reader and Acrobat v9.x for Windows, Macintosh and UNIX operating systems," the company said.
The "authplay.dll" mentioned in the advisory is the interpreter that handles Flash content embedded within PDF files, and is present on any machine equipped with Reader and Acrobat.
Adobe said it would patch all versions of Flash by July 30, and Reader and Acrobat for Windows and Mac no later than July 31. Until a patch is available, Adobe said users could delete or rename authplay.dll, or disable Flash rendering to stymie attacks within malformed PDF files. Adobe did not offer any similar workaround for Flash and could only recommend that "users should exercise caution in browsing untrusted websites."
The U.S. Computer Emergency Response Team (US-CERT), part of the Department of Homeland Security, included instructions on how to delete the Flash interpreter from Windows, Mac and Linux machines in a Wednesday advisory of its own.
Unlike previous PDF-based attacks, disabling the application's use of JavaScript does no good. Firefox users can install the NoScript add-on to block Flash directed at the browser, and Windows Vista users are shielded from silent attacks by the operating system's User Account Control (UAC) prompts.
While Adobe stopped short in its advisory and an accompanying blog post of confirming attacks, more security companies stepped forward Wednesday to report they had spotted not only hacks using rigged PDF documents, but also drive-by attacks launched from compromised Web sites.
Most attacks reported so far have been exploits served by malicious PDF files. "The PDF here is just the vehicle for the attack," explained Marc Rossi, the manager of development at Symantec. In those cases, the exploit relies on the flawed authplay.dll installed with Reader. "But it's not like you need to have both Flash and Reader on your system," added Rossi. "The possibility definitely exists that a malicious Flash stream from a Web site could exploit this."
That's exactly what others are reporting. Mid-day Wednesday, Paul Royal, a principal researcher at Purewire, said in an e-mail that he had found multiple malicious sites serving up Flash-based attacks. Later in the day, SANS' Internet Storm Center (ISC) echoed Royal. "We [have] confirmed that the links have been injected in legitimate web sites to create a drive-by attack, as expected," ISC handler Bojan Zdrnja said in a warning on the center's site.

"We [have] confirmed that the links have been injected in legitimate web sites to create a drive-by attack, as expected," ISC handler Bojan Zdrnja said in a warning on the center's site.
Exploits remain few in number, but Rossi expected them to ramp up quickly. "We're seeing very limited exploitation so far, which is pretty typical. PDF attacks tend to start out as targeted e-mail attacks, with an [poisoned] attachment, directed at specific people." After the exploit gains access to the PC -- all in-the-wild attacks seen so far target Windows machines -- it "phones home" to a Web site, Rossi said, to download a Trojan onto the compromised system.
Purewire's Royal noticed that the flaw in Flash was first logged into Adobe's bug-tracking database Dec. 31, 20008, but the current exploit code appears to have been crafted much more recently, on July 9. It's possible that attacks have been in circulation since then. "The bug has apparently existed since December 2008," Royal said.
Although Adobe blocked access to the bug's page for several hours Wednesday night, it reopened the page by about 1 a.m. Eastern today. As Royal reported, the "Created" date for the bug was listed as "12/31/08" on the Adobe Flash Player Bug and Issue Management System.
Adobe has been under the security microscope this week. On Monday, Danish bug tracker Secunia noticed that Adobe continues to provide an outdated edition of Reader for download from its Web site, a practice Adobe originally defended as necessary to produce patches quickly. Tuesday, however, Adobe said it was reevaluating Reader's updating process to close the exploit window.

Microsoft revenue declined 17% and net income declined 29% year over year in the company's fiscal 2009 fourth quarter due to continued weakness in global sales of PCs and hardware servers, the company reported Thursday.
Revenue of $13.1 billion and earnings per share (EPS) of 34 cents slightly missed analysts' forecasts for the quarter that ended June 30. Quarterly earnings were affected by a 2-cent reduction due to $276 million in deferred revenue related to Microsoft's Windows 7 Upgrade Option program announced June 25, Microsoft said. Thomson Reuters analysts were expecting revenue of $14.37 billion and earnings per share of 36 cents for the quarter.
Operating income for the quarter was $3.99 billion, a decline of 30% year over year, and net income was $3.05 billion, a decline of 29% year over year.
Analysts were expecting revenue to be deferred to the December quarter, or later, because of the Windows 7 upgrade program, which allows people to purchase PCs now with the right to upgrade to Windows 7 when it becomes available. Microsoft can't report that Windows 7 revenue until the upgrade occurs, which will be at least after the software's Oct. 22 availability date.
However, analysts still largely expected Microsoft to meet or even slightly beat consensus estimates for the quarter despite the deferred revenue.
They also thought that Gartner's outlook for the PC market, released last week, would reflect positively on Microsoft's fourth-quarter results. Gartner had expected a 10% year-over-year decline in PC unit shipments for the second calendar quarter, but ended up estimating a 5% decline instead. However, Gartner's PC shipment predictions still could bode well for Microsoft when Windows 7 is released in October.
Microsoft's results also were affected by $193 million in legal charges, $108 million of impairments to investments and $40 million of additional severance charges related to a previously announced severance plan, the company said.
Revenue for the full fiscal year that ended June 30 was $58.44 billion, a 3% decline from the prior year. Operating income was $20.36 billion for the year, a decline of 9%, while net income was $14.57 billion, a decline of 18%. Diluted EPS for the year was $1.62, a decline of 13% from the previous year.
On a positive note, Microsoft said it took $750 million out of its operational costs for the quarter as it continued to enact cost-cutting measures to navigate the challenging economic environment. In January, Microsoft announced its first-ever layoffs as part of these measures, and also cut back on traveling expenses and contracts with short-term employees.

Microsoft admits it can't stop Office file format hacks
Label: Computer NewsPlans to build 'sandbox' around questionable docs in Office 2010 as defense
By Gregg Keizer
Microsoft's plan to "sandbox" Office documents in the next version of its application suite is an admission that the company can't keep hackers from exploiting file format bugs, a security analyst said today.
"What's been happening is that Office has lots of vulnerabilities," said John Pescatore, Gartner's primary security analyst. "For the past 18 months, hackers have been fuzzing Office file formats," he said, referring to the practice of "fuzzing," a tactic that relies on automated tools that drop random data into applications to see if, and where, breakdowns occur.
Fuzzing has been a hacker's best friend: Microsoft has repeatedly had to patch file format vulnerabilities in Office applications, most recently in July when it fixed a flaw in Publisher 2007 and in June, when it patched seven vulnerabilities in Excel and two more in Word.
"What's happening is that the bad guys are using fuzzing tools to find vulnerabilities in Office, and now Microsoft is saying, 'Okay, we can't find, let alone fix, every vulnerability. So here's a way to put a sandbox around the vulnerability."
The sandbox technique Pescatore mentioned is a new addition to Office 2010, the upcoming upgrade to Microsoft's bestselling Windows application suite.
According to Brad Albrecht, a senior security program manager with the Office team, Office 2010 will sport something called "Protected View" that isolates Word, Excel and PowerPoint files in a read-only environment. The sandbox, said Albrecht in a post to a company blog this week, will have "minimal access to the system, and no access to your other files and information. Even if the file is malicious, it can't get out of the sandbox and do harm to your computer or data."
"That's a good thing," Pescatore agreed. "Sandboxing and isolation are always good things in security, if only to limit the damage of a malicious file."
Albrecht also spelled out other security measures that Office 2010 will implement, including a more flexible file blocker and a suite-wide roll-out of "Office File Validation," a practice that was rolled out in Publisher 2007 Service Pack 2 (SP2).
The file blocker, introduced in Office 2007 then back-ported to Office 2003 in September 2007 with SP3, automatically bars access to some document types. Albrecht said that Office 2010 will let users fine-tune the feature to better manage which formats Word, Excel and PowerPoint open.
"File blocking was a real broad-brush thing in Office 2007," said Pescatore, "and it would give users obscure error messages." He applauded the move toward flexibility in the file blocker.
Office File Validation, meanwhile, is a system that validates older, pre-XML file formats for Word, Excel and PowerPoint, then blocks those that don't conform to the documented format. Documents that contain malicious code would presumably trigger the block. At that point, Office 2010 will hand off the file to the Protected View sandbox.
"There's still a trade-off," said Pescatore, talking about the improved security Microsoft plans for Office 2010. "The file in the sandbox is read-only, but if I need to open it and add something to it, that's going to annoy users."
Another downside, said Pescatore: Sandboxing, which is essentially lightweight versions of virtual machines, consumes PC resources. "On the other hand, PCs are getting faster, so we have the ability to throw more cycles at [sandboxes]."
Albrecht claimed that the new security features in Office 2010 would have "an indistinguishable performance impact on your [document] load time," but didn't go into detail about system requirements or the impact on the machine's memory and processor resources.
Microsoft declined to make Albrecht available to answer follow-up questions about Office 2010's security plans.
But Pescatore likes what he sees in Microsoft's bird's-eye view. "To build a sandbox, especially around Word docs, that's a very good idea."

Computer Internet Security
Internet is the main source for computer viruses. visit computervirus removal page for more information on this.
The Internet is a client-server system. Your computer is the client, and the computer which stores the data is the server. When you click onto a website, your computer requests the web page from the specific server storing that file. That server sends the data you've requested over the internet to your computer. Your web browser interprets the data and displays it on your computer screen.

Computer input devices are the components that have been used to pass data into a computer to process and provide the desired output. The input data could be letters, numbers, images or sound.
Most of the computer input devices are common to home or office environments. However, there are devices that are not commonly available.
General Computer Input Devices
Keyboard
Mouse
Joysticks
Scanners
Special Computer Input devices
Touch screens
In touch screens, users have to press (touch) areas on the screen to pass data. A typical usage of the Touch Screen technology is some Bank ATM machines.
Smart Cards
This input device stores data in a microprocessor embedded in the card. This allows information, which can be updated, to be stored on the card. This method is used in store cards which accumulate points for the purchaser, and to store phone numbers for cellular phones.
Light pen
A Light Pen is a pointing device shaped like a pen and is connected to a VDU. The tip of the light pen contains a light-sensitive element which, when placed against the screen, detects the light from the screen enabling the computer to identify the location of the pen on the screen. Light pens have the advantage of 'drawing' directly onto the screen, but this can become uncomfortable, and they are not as accurate as digitising tablets.
OCR (Optical Character Recognition)
OCR is designed to translate images of typewritten text (usually captured by a scanner) into machine-editable text, or to translate pictures of characters into a standard encoding scheme representing them in (ASCII or Unicode). OCR began as a field of research in artificial intelligence and machine vision. Though academic research in the field continues, the focus on OCR has shifted to implementation of proven techniques.
Optical Mark Reader (OMR)
The Optical Mark Reader (OMR) can read information in the form of numbers or letters and put it into the computer. The marks have to be precisely located as in multiple choice test papers.
Bar Code Reader
You might have seen bar codes on goods in supermarkets, in libraries and on magazines. Bar codes provide a quick method of recording the sale of items. A bar code is a pattern printed in lines of differing thickness. The system gives fast and error-free entry of information into the computer.
