It's powered by the 64-bit 1.7 GHz AMD Athlon 64 X2 TK-53 processor, which allows you to easily run multiple programs without slowing down your productivity. This notebook also features a 120 GB hard drive, 1 GB of installed RAM (2 GB maximum), built-in 54g Wi-Fi connectivity (802.11b/g), 8x multi-format/dual-layer DVD+/-RW drive (which also burns CDs), ExpressCard slot, and NVIDIA GeForce Go 6150 video/graphics card.

It comes preinstalled with Microsoft Windows Vista Home Premium, 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 1.7 GHz AMD Athlon 64 X2 TK-53 processor offers a dual-core architecture, which delivers additional computing resources to help expand your PC'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 and 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 256 KB L2 cache (for a 512 KB 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 120 GB hard drive (5400 RPM) offers enough to room to hold a digital audio library of over 20,000 songs and still have room left over for movies, games, and a large collection of software. This Serial ATA (SATA) hard drive also quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0.

• Memory: The 1 GB of installed RAM (2 x 512 MB) is a good start, but you'll want to add more RAM to handle today's demanding multimedia and productivity suites. This notebook has a 2 GB maximum RAM capacity (2 x 1 GB). Also, to receive the benefits of the dual-channel DDR2 RAM, any RAM additions require memory modules of same capacity and clockspeed.

• 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.

• 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).

Networking, Connectivity & Expansion
This notebook has an integrated 54g wireless LAN that's fully compatible with 802.11b/g wireless networks. It also includes a next-generation ExpressCard 54/34 card slot (though no standard PCMCIA slot), which lets you take advantage of thinner, faster, and lighter expansion cards for even more advanced wireless, networking, storage, and security features. You get a good offering of connectivity options:

• 3 USB 2.0 ports for connecting a wide range of peripherals--from digital cameras to MP3 players
• 1 FireWire (also known as IEEE 1394 or i.Link) port for connecting digital video camcorders and other peripherals
• 1 VGA monitor port
• 1 S-Video port for connecting to a TV
• 1 ExpressCard 54/34
• 2 headphone jacks (1 with S/PDIF digital audio compatibility) and 1 microphone jack

• 1 consumer IR (infrared)
• 5-in-1 memory card reader (Secure Digital, MultiMedia, Memory Stick, Memory Stick PRO, xD Picture Card)
