A4Tech introduces a padless mouse

A mouse without a need of a mouse pad—that is exactly what A4Tech V-Track mouse is all about as it is capable on running on any surface and cleverly gets rid of the movement restrictions brought about by rectangular-shaped pads. And by anywhere, A4Tech means that the mouse could really function on almost anything under the sun, including surfaces which are typically not suitable for the normal optical mouse such as an uneven surface, slightly dusty glass, marble, soft 3D fabrics like beds, and even on furry textiles.

A4Tech’s V-Track technology uses vertical incident light instead of the regular slanted light which traditional mouse models offer, allowing it to function perfectly on various surfaces and ensure perfect precision. The V-Track mouse promises to provide perfect cursor direction and speed as well as resolve regular mouse’s adaptability problems of slow-moving cursor when working on glossy, uneven or multi-color surfaces.

The V-Track mouse features a four-way wheel which allows for a smart vertical and horizontal scroll for limitless movements. The mouse also gives power-saving benefits with its shorter light path, providing 20 percent to 30 percent less power than those of the regular optical mouse. V-Track also offers better resistance to dust with a tiny lens aperture which prevents dust accumulation compared to larger lens holes that just gather dust and affects the mouse’s speed and performance.

Prices range at P350 to P450 for the wired and P700 to P850 for the wireless, cheaper than other brands in the market considering its innovative technology features.

Samsung to be unveiled the Next Gen of AMOLED

Samsung will be unveiling the next generation of AMOLED (Active-matrix organic light-emitting diode) displays during CES 2011 next week. AMOLED is the technology used in TVs and mobile devices. An AMOLED display includes of a matrix of OLED (organic light-emitting diode) pixels that generate light. The current flowing to each pixel is controlled by a thin film transistor (TFT) array that functions as a series of switches.

During CES 2011, Samsung will unveil a 4.5-inch 800 x 480 (WVGA) resolution flexible AMOLED display concept prototype. This AMOLED display technology will be used for mobile devices. It is 2 mm thick and can be rolled down to a radius of 1 cm.

How to Install Windows XP and Remove Windows Vista

How to Install Windows XP and Remove Windows Vista
Windows Vista is not yet perfected and chances are you will reach the point where you want to revert to Windows XP. But the task is easier said than done especially if you want a clean copy of Windows XP on your PC. With that in mind, what can you do to uninstall Windows Vista and install Windows XP on your computer? Well, I had that problem last week and much as I looked for solutions on the web, I discovered a different way to remove Windows Vista and install a fresh Windows XP operating system.

How? Follow these steps.

1. Grab a hold of the usual bootable DOS disk. Some peripherals (particularly laptops) no longer come with the traditional floppy drives but not to worry. You can still download the DOS system from sites and burn them on a CD which you can use to boot.

2. Boot up your PC using the CD ROM as your first boot device. Allow it to load and then run the handy FDISK like before.

3. View the partitions on your hard drive and delete them one by one. Make sure you don’t leave any drive intact to make sure you get a RAW drive ready for formatting.

NOTE: As far as backups are concerned, this guide assumes that they have been already backed up or that the user wants to completely erase the Windows Vista OS.

4. After all partitions have been deleted or removed, place your Windows XP setup disk and restart the computer. Now you can install the Windows XP OS as you would in any first time setup. Some people have tried to use the dual boot which is really ridiculous.

For one, it eats up space and second why would you leave an operating system when you have no plans of using it. Some have even said that it causes problems so why leave it there in the first place?

Also, if at times you are attempting to overwrite Windows Vista, chances are your Windows XP setup will not even reach the first screen setup (blue screen). Such is the problem I had experienced that led me to find an alternative to which is itemized above.

These steps are guaranteed. Don’t let Windows Vista be a pain. You can outthink Windows Vista using the traditional way of formatting a computer, similar to the first time you install Windows XP.

How to Clean Computer Keyboard

If you are using just a damp cloth to wipe the screen, be sure to dry it off as well to prevent streaking. When cleaning the Computer monitor casing use a soft cloth with your cleaning fluid. Always spray onto the cloth, not the equipment! Turn the keyboard upside down and shake so loose dust, dirt, and food crumbs will fall out. Spray between the keys with compressed air or vacuum the keyboard. For hard to remove stains such as ink, use a cotton ball with rubbing alcohol or an alcohol saturated wipe.

Let those nasty little keys soak for a bit. Once you are finished cleaning the keyboard proper, dry the keys using a lint-free rag or towel. This will remove any remaining filth. Next, place them on a towel. The inner spaces will still need to air dry for awhile – NEVER put wet keys back onto the keyboard. Water has a Jihad out on circuitry. Be patient; you’re halfway clean keyboard. ed outside will suffice. You may need a toothpick for sludge scraping. Run cotton balls (I use swabs for the tight spaces) damp with isopropyl alcohol along the rows and around the rest of the keyboard, including the palm rests, large keys, and outer edges. Squeeze excess fluid out of the cotton before application, and never apply the alcohol directly to the keyboard.
