How bad pixels appear? First, even a new laptop with a new LCD screen can be sold with defective pixels (defects). Sure, that’s not fair to sell a product that most people will not accept it if they knew of this defect. But things are still happening unfair. Second, they can occur later due to poor technology, for example, TFT (thin film transistor connected to the pixels) can be degraded and eventually destroyed. Thirdly, the LCD screen is more vulnerable than older CRT pixels are wrong and can easily be rendered by computer users by bringing pressure to bear on the screen.

Many computer users assume that even a single dead pixel is enough to need changing. But very often the manufacturers warranty for most of the screen with dead pixels are not interchangeable. Some notebook manufacturers have their own policies about how many dead pixel is enough to be replaced. For example, Dell believes that the LCD screen is broken only if more than five dead pixels. Besides, if the return policy is not possible to notebook manufacturers the LCD screen to replace a pixel that is damaged, please consider other alternatives to yourself.

As noted above, a pixel is different in nature and therefore called, require a different approach to adopt. Stuck pixels sometimes start and hot working again with time. Another good news is that sometimes one pixel energy back through on and off quickly. To this end, try a few pixels to introduce the software to improve.

You will find many suggestions on the Internet. Some of them are not good (for example, by using excess heat to restore defective pixels), the other must try. Anyway, it’s better to try different approaches to repair a damaged pixel, at least, to ensure that there is only one option left – on the LCD screen replaced. Unfortunately, if you have a dead or partially dead pixel (s), in many cases there is nothing you can do than buying a new LCD screen.

When exposing the screen, find the label on the back shows the number of producers. This usually consists of one or more letters followed by a series of numbers. To determine the format compatible with your laptop screen or if you have difficulty determining the model number of your old screen, you can use some online manual illustrations.

Because the producer most responsible for the laptop too much, you can try to third companies in a market that sells laptop screen to find. Some places have a large stock of brand new LCD screen to replace the notebook. If you can not find a particular model listed on their site, please call or email to ask if they can help you find a replacement screen for a laptop.

Backup to external hard drive easily, safely and efficiently.

Make sure you actually remember the password encryption. You can also save your external hard drive off site (home of a friend, paid a criminal or specialized storage place anti-fire) in case your information is very important (and, generally, anyone can do and it can not hurt for sure).

As external hard drives have the cheapest storage volume (about 200 GB for $ 150?) And you can reuse it for several years, we may as well get the cheapest backup medium available. When you use a backup program, you can simply save the backup program run when you are away (or maybe even at night) to backup everything without supervision. If you need two or more backup disks, so you can get another external hard drive.

In addition, there are now large enough mobile hard drives, which may allow all necessary data: working papers, e-mail files, etc. You can also take your data wherever you want and feel safe, because some External hard drives are now difficult to break a fall.

So, go with an external hard disk backup and fast as you want, whenever you want, secure your important data, get the cheapest backup and even be able to perform your backups where you want .

At IDF (Intel Developer Forum) in San Francisco last week, the device with a USB 3.0 connection began to appear – a Webcam and some prototype devices. But other products are still absent.

Fortunately, not long after Freecom, external hard drive manufacturers are not too prominent, finally admitted that they already have a USB 3.0 external hard drives – which also is the petama in the world.

From the outside, Hard Drive 3.0 XS looked ordinary, like a portable hard drive. Yet there is beauty on the inside. As the world’s first hard drive that uses USB SuperSpeed technology, these drives can transfer data referred to 130MB/sec. XS 3.0 Hard Drive is also a desktop hard drive 3.5 “smallest moment, users can cram up to 2TB in his enclosure, and like other USB 3.0 drive that will be present, this one backwards compatible with USB 2.0 devices.

Hard Drive 3.0 XS will be available in continental Europe from mid-November in the capacity of 1TB, 1.5 TB and 2TB, with a price of 119 Euros (U.S. $ 174.29) for a capacity of 1TB.

Viewed from the physical, this iMac is not experiencing a change from the previous generation. Looks like Apple is still quite satisfied with this design and consider it not necessary to make physical changes. Just changing the guts of a PC with this compact design. Processor, memory and store the media capacity greater than the iMac is the mainstay of this new generation.

In 24-inch version, Apple put an Intel Core 2 Duo 3.06GHz which is supported with the installation of performance DDR3 memory for 4GB. Media store that is placed too unsparing. There is a conventional hard disk with a velocity around 7200 rpm 1TB capacity installed here. With this large storage capacity, it will need some time for you to make full. But if you are still not enough, you still may move the files that were not so important to the DVD disc by using a slot-loading 8x SuperDrive provided.

NVIDIA GeForce 130 GT with 512MB memory is Apple’s choice of VGA card installed in your PC. For daily use, this graphics card it also has more than sufficient. After treated with this graphics card, the display will be brought to the screen 24 inch wide LCD. Speaking of the screen, it looks like it’s where lies the weakness iMac. Although this screen was clear and bright, but its viewing angle is not too broad.

Problem connectivity, Apple provides Bluetooth 2.1, AirPort Extreme wireless networking, Gigabit Ethernet port, FireWire 800 port, and four USB 2.0 ports. ISight webcam while still using the keyboard packaged experienced little change.

As part of the desktop platform in mainstream classes, AMD today introduced the Quad-Core their first cheap, less valuable than U.S. $ 100.

With the balance of power of AMD Athlon II X4 quad-core processors, and AMD 785G chipset featured ATI Radeon HD 4200, AMD seemed to welcome the arrival of Windows 7, the HD spec the computer graphics.

When juxtaposed with the processors ‘neighbors’ that class, but valuable competitive, AMD Athlon processor 620 II X4 more likely to be superior in terms of multi-tasking, in addition to the price that much cheaper.

AMD products in mainstream classes are also designed to be more effective in working with HD graphics. For example ATI Stream Technology, which allows hardware acceleration which makes the conversion rate increased HD video formats.

AMD’s products were welcomed with open arms by HP, as topnotch IT companies in the world.

“Our goal is to produce a superior computer performance, and maximize the value of these computers to our customers,” said John Cook, Vice President of Marketing, the global PC business, HP, as quoted from Techpowerup, Friday (18/9/2009) .
