Processor
At the heart of any computer lies the CPU (or
processor), a massive collection of miniature
transistors that governs the speed and power of the
entire unit. Some of today's notebooks are equipped with
high-end CPUs on par with those found in top-of-the-line
desktop PCs, while others are quick enough only for
basic duties such as word processing, e-mail, and the
like. The VAIO VGN-A250 is equipped with an Intel
Pentium M 725 processor operating at 1.6 GHz. This is
one of three components that comprise Intel's efficient
Centrino system (the others being a specialized Intel
chipset and integrated wireless support). Centrino-equipped
notebooks are generally smaller, easier on the
batteries, and more versatile than their non-Centrino
counterparts. This particular CPU is part of Intel's
upgraded Pentium M lineup, featuring an amazing 2 MB of
Level 2 cache for extremely fast access to recently
opened data and a fast 400 MHz front side bus to help
reduce data-streaming bottlenecks. Though its raw clock
speed is not on par with that of a high-end Intel
Pentium or AMD Athlon, this CPU will easily handle most
every mobile task while at the same time improving
battery life. Moreover, Sony has equipped the system
with solid graphics support and adequate memory--two
components vital to overall performance.
Memory
Computers typically store information on their hard
drives, but they keep frequently and recently accessed
data in random access memory (RAM) for faster retrieval.
More RAM means more efficient computing, superior
multitasking, and less strain on your hard drive. The
VAIO VGN-A250 incorporates 1.25GB of RAM. This is
considered a SUPERB allotment for high-end notebooks,
delivering solid multitasking and few slowdowns during
ultracomplex tasks. |
The VGN-A250 features a
15.4-inch screen.

Video
CPUs are usually so busy doing basic calculations that they need
help translating visual output to the screen. This is the duty
of the graphics card (or graphics controller). This system's
graphics controller is an ATI Mobility Radeon 9200 with 64 MB of
dedicated video RAM. Dedicated video memory is far preferable to
shared video memory (where the graphics controller appropriates
a portion of the main system memory), and this 64 MB allotment
is considered plenty for 3-D graphics, 3-D animation packages,
and even the latest 3-D games.
Display
The VAIO VGN-A250's 15.4-inch WXGA display may be
smaller than the 17-inch monsters found in today's
top-of-the-line notebook displays, yet it's larger than
that of most notebooks and even some desktops.
Furthermore, its widescreen format is perfectly tailored
to the aspect ratio favored by DVD movies. It's highly
sophisticated, too, sporting Sony's new XBRITE
technology for better contrast and a brighter picture,
and a crisp 1,280 x 800 maximum resolution.
Hard Disk
At a spacious 80 GB, the enclosed hard drive is a
welcome perk for those who need to operate a broad range
of applications and also keep a large library of
space-gobbling music or multimedia files.
Audio
The unit is equipped with integrated stereo speakers and
an audio amplifier. |

Optical Drive
An optical drive is essential in today's computing environment.
A CD-ROM drive allows you to install CD-based applications and
play music CDs. A CD-RW drive adds CD burning, so you can also
back up your important files to long-lasting discs and create
personalized music CDs. With a DVD-ROM drive you can watch DVD
movies. And with a DVD-RW drive, you can write home movies to
durable discs and archive files to DVDs, which boast more than
seven times the storage capacity of CDs. Some drives allow you
to do a combination of all of these tasks. This system features
a DVD+R Double Layer/DVD±RW Drive, with which you can do all of
the above. The drive also supports today's hot new double-layer
DVD format that effectively doubles the capacity of typical
DVDs.
Keyboard and Controls
You'll control your notebook via an 82-key keyboard and a
standard electrostatic touchpad.
Connectivity and Expansion
The VAIO VGN-A250 features a bevy of connectivity facilities,
including a 56K modem for low-speed dialup Internet and e-mail
access, a 10BASE-T/100BASE-TX Ethernet port for high-speed wired
networking and Internet, and an integrated Intel PRO/Wireless
2200BG network connection (802.11b/g) for cord-free
e-communication at home, at the office, or on the road at a
public hotspot. Other key amenities include high-speed USB 2.0
ports for plug-and-play devices such as external drives and
digital cameras, an IEEE 1394 FireWire port (commonly used for
quick data uploads from digital camcorders), and the usual
impressive Sony roster of audio and video ins and outs.
Operating System and Software
Sony will install Microsoft's Windows XP Home Edition operating
system, a variety of productivity and business applications, and
a broad range of digital photo, audio, and video utilities.
Dimensions and Weight
Many of today's most powerful notebooks are also the largest,
weighing ten or twelve pounds or more and therefore too big and
cumbersome for extensive, continuous traveling. These are often
referred to as "desktop replacements". On the other extreme are
"thin and lights" or "ultraportables", super-miniaturized units
that are typically less powerful than their larger brethren but
weigh as little as two pounds and often fit comfortably inside a
large purse. The VAIO VGN-A250 is just below today's median at
7.3 pounds and 14.7 by 10.9 by 1.7 inches.
