HP Pavilion Special Edition

>> Thursday

Built for today's multimedia-savvy, always on-the-go computer user, the entertainment-centric HP Pavilion dv2840se notebook PC provides quick access to your digital audio and video library wherever you roam. Weighing in at 5.25 pounds, it features the HP exclusive high-gloss, organic Verve imprint fini

sh, which flows freely across the top cover then bursts across the palm rest area. A significant change in color appears as well, with a rich bronze top cover carrying through to the palm rest area to morph into golden copper shades then fade to deep black near the touch-sensitive media control panel. It offers a widescreen, BrightView 14.1-inch display, which provides improved viewing in direct sunlight. Control settings for audio and video playback from up to 10 feet away with the included HP remote, then store it conveniently in the PC card slot. Enjoy movies or music in seconds with the external DVD or music buttons to launch HP QuickPlay (which bypasses the boot process).

Optimized for mobile performance, it's powered by the 2.1 GHz AMD Turion 64 X2 TL-62 dual-core processor, which offers 64-bit computing capability and higher throughput for simultaneous computing tasks. Other features include a 250 GB hard drive, 4 GB of installed RAM (maximizing capacity), quad-mode Wi-Fi LAN (802.11a/b/g/n), multi-format/dual-layer LightScribe DVD drive (which can also burn CDs), Nvidia GeForce Go 7150M video card with up to 1071 MB of total available video memory, multi-format memory card reader, integrated Webcam for easy video conferencing, and Bluetooth wireless connectivity to your peripherals and communication headsets.

It comes preinstalled with Microsoft Windows Vista Home Premium (Service Pack 1), which includes all of the Windows Media Center capabilities for turning your PC into an all-in-one home entertainment center. In addition to easily playing your DVD movies and managing your digital audio library, you'll be able to record and watch your favorite TV shows (even HDTV). Vista also integrates new search tools throughout the operating system, includes new parental control features, and offers new tools that can warn you of impending hardware failures.

The Basics

Processor: The 2.1 GHz AMD Turion 64 X2 TL-62 processor offers a dual-core architecture, which delivers additional computing resources to help expand your PCâ€™s capabilities by providing higher throughput and simultaneous computing--increasing your performance by up to 80 percent. You'll be able to perform multiple tasks such as digital rendering a

nd gaming all while running virus scan or other background tasks seamlessly thanks to the innovative Direct Connect Architecture. And it's designed to handle simultaneous 32- and 64-bit computing with no degradation in performance. You'll enjoy long battery life thanks to the AMD PowerNow! power management technology, which delivers performance on demand and can extend system battery life up to 65 percent. And the AMD Digital Media XPress technology delivers stellar multimedia performance and playback on digital entertainment such as games, streaming video and audio, DVDs, and music.

Each processing core has a 512 KB L2 cache (for a 1 MB total), and this processor can deliver up to a 1600 MHz system bus for lightning quick computing reflexes. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

Hard Drive: The extra-large 250 GB Serial ATA hard drive (5400 RPM) provides more than enough capacity for storing a large audio and video library, as well as extra space required for video editing. This SATA hard drive also quickens the pace with a higher speed transfer of data--akin to Firewire and USB 2.0.

Memory: The 4 GB of installed RAM (PC5300, 2 x 2 GB) maximizes the capacity for this notebook. It also offers a top-of-class 667 MHz speed and boosts the amount of available video RAM that's shared with this notebook's video card.

DVD/CD Drive: This multiformat DVD/CD drive is compatible with writing both DVD+ and DVD- disc formats as well as dual-layer (DL) DVD+/-R discs, which can store up to 8.5 GB of data. It features 4x DVD-R DL Write Once, 2.4x DVD+R DL Write Once, 8x DVD+R, 4x DVD+RW, 8x DVD-R, 4x DVD-RW, 16x DVD-ROM, 40x CD-R, 24x CD-RW, and 40x CD-ROM speeds.

This LightScribe DVD±RW drive lets you laser-etch silkscreen quality text and images on to CDs and DVDs . Your software, PC and discs work together for a no-hassle way to burn just the labels you want. After you burn content, just flip the disc over, reinsert and burn your label--anything from a simple title to a full-disc work of art.

Keyboard & Mouse: This notebook has a 101-key keyboard and a touchpad with on/off button and dedicated vertical/horizontal Scroll Up/Down pad. It also includes two quick-launch buttons (HP QuickPlay Music and DVD).

Hotspots a Hot Topic

Some report an unusual sensitivity to the waves emitted in these hotspots. Officially, the levels of WiFi electromagnetic radiation emitted into the environment in a hotspot are well below recommended levels and there is no evidence of any risk to humans. Yet some people blame Wi-Fi exposure for everything from sleep disturbances, headaches and blurred vision, to heart and breathing problems.

Because no study has ever shown a conclusive risk to human health from exposure to these low-frequency radio transmissions, many simply shrug off the complaints of these people, choosing to believe their symptoms are coincidental or caused by another source.

So just how high are the levels of radiation in a hotspot? According to Dr. Michael Clark of the HPA, the published research on mobile phones and wireless networks does not indicate a risk to human health. "All the expert reviews done here and abroad indicate that there is unlikely to be a health risk from wireless networks," he says. "The few studies on mobile phone masts that have appeared in peer-reviewed journals claiming to observe health effects are not at all conclusive. The real problem is deciding what level of precaution is appropriate.

"When we have conducted measurements in schools, typical exposures from wi-fi are around 20 millionths of the international guideline levels of exposure to radiation. As a comparison, a child on a mobile phone receives up to 50 per cent of guideline levels. So a year sitting in a classroom near a wireless network is roughly equivalent to 20 minutes on a mobile. If wi-fi should be taken out of schools, then the mobile phone network should be shut down, too - and FM radio and TV, as the strength of their signals is similar to that from wi-fi in classrooms."

WiFi Radiation - Is WiFi Technology Bad For Your Health?

The technological benefits of Wireless Fidelity technology versus the wireless hazards is a hot debate in many different countries. In the United States, a class action lawsuit has been brought against a school board who use the technology in their classrooms. In Britain, it has been removed from some classrooms altogether. Are these precautionary measures necessary, or simply the reaction of a public frightened by a technology they do not fully understand?

What is WiFi?
It is possible to form a somewhat informed opinion on the safety or potential risks of this new technology without actually being a physicist yourself.

Quite simply, Wi-Fi or WiFi is the wireless technology most commonly used to connect people to the internet in schools, coffee shops, hotels and other network locations, or to connect cell phone users to one another. Wi-Fi is certainly convenient for travellers and students, but is it dangerous? Many believe that the low-level electromagentic waves that radiate from the wireless internet source to each individual user can be harmful to your health, even causing cellular changes and possibly cancer.

The area covered by a Wi-Fi internet connection is known as a "hotspot"; this is the area in which the waves radiate to give users access to the internet. It can span several kilometers, although the waves cannot pass through treed areas. While in the hotspot, a laptop user can simply connect to the network, access the internet, and check their email or do their other business on the run.

A wireless network uses radio waves to send communications across a two-way network. A computer's wireless adapter translates the internet connection data into a radio wave and sends it to the wireless router - the one in your laptop. This process works in reverse as well, sending a radio signal back to the host computer.
