Apple PowerBook G4 (12-inch, SuperDrive) Review

No one can argue that the 12-inch Apple PowerBook G4 isn't attractive -- you get a competitive set of hardware, including a roomy, 80GB hard drive, a single-layer DVD burner, and a DVI connection, as well as an absolutely best-in-class software package.

Though we think the 12 inch iBook G4 is the better choice for basic users, we think the 12-inch PowerBook offers a better combination of power, features and battery life for the price than any other Apple laptop. As such, unless you engage in video editing on the fly or have some other essential reason to haul around a 15- or 17-inch display, we recommend the cheaper, more compact 12-inch model to the larger PowerBooks. (Use the money you'll save to buy an LCD monitor to use with your laptop at home or at work.)

DesignThe 12-inch PowerBook G4's rock-solid, aluminium-alloy case is an upscale adaptation of Apple's less expensive polycarbonate iBook G4. The 12-inch PowerBook G4 is smaller than the 12-inch iBook G4, measuring a modest 277mm wide, 218mm deep and 30mm thick. At 2.1kg, it's on the lighter side of the thin-and-light spectrum.

Like the iBook G4, the PowerBook G4 has a comfortable keyboard with rounded keys shaped to fit your fingers; our only gripe is the grossly undersize arrow keypad. The spacious touch pad's two-finger scrolling feature, for scrolling horizontally and vertically, is magical (use it for a few days, and you'll wonder how you ever did without it). The display, which actually measures 12.1-inches, features a standard 1,024x768-pixel native resolution -- not optimal for graphics work but adequate for general use; many 12-inch PowerBook G4 owners use an external display at home or work. We like the laptop's speakers, which hide underneath the central screen hinge yet somehow provide rich, multilayered sound. The 12-inch PowerBook G4 lacks the external multimedia controls found on many other laptops -- that's the price you pay for a streamlined design. A note of caution to those who live in cold climates: the aluminium-alloy wrist rest can feel downright chilly until your typing hands warm it up.

FeaturesAll of the PowerBook G4's ports sit along its left edge. They're largely similar to what you'll find on the 12-inch iBook G4. For networking, the 12-inch PowerBook provides 56Kbps modem and 10/100 Ethernet ports. Also onboard are connections for headphones, audio line-in (which the iBook lacks), power, two USB 2.0 ports, a mini-DVI port that accommodates adaptors for DVI, VGA, S-Video and composite video connections. Our test unit also had a six-pin, 400Mbps FireWire port. The opposite edge hosts the slot-loading single-layer DVD burner, which we prefer to a breakable optical-drive tray.

Like the iBook G4, the PowerBook G4 lacks a true productivity suite, but it ships with a very strong software package. You get the latest version of the terrific Mac OS X, nicknamed Tiger, plus Apple's excellent iLife '05 software bundle for managing photos (iPhoto), videos (iMovie) and music (iTunes). Also included are more professional-grade apps, including Art Directors Toolkit, OmniOutliner and QuickBooks for Mac.

We think it's a bit high for the uneven mix of high-end and low-end specs: a 1.5GHz PowerPC G4 processor, 512MB of slowish 333MHz memory (upgradable to 1.25GB), an Nvidia GeForce FX Go 5200 graphics chip with 64MB of dedicated VRAM, Airport Extreme 802.11g wireless, a spanking-new Bluetooth 2.0+EDR card, and a big 80GB, 5,400rpm hard drive protected by Apple's Sudden Motion Sensor technology, which stops it from spinning when it detects imminent damage.

PerformanceIn our tests, the 12-inch PowerBook G4 excelled with productivity tasks. Using iTunes, it converted a music file into MP3 format in the same fast time as the beefier 15-inch version and surpassed the larger model by more than one minute in our Photoshop CS trials. Despite its small size, the 12-inch PowerBook G4 has the chops for serious graphics work.

Review: Nikon D40

The D40 is Nikon's new entry-level digital SLR. the D40 is one of the lowest priced SLRs on the market. Nikon didn't cut a lot of corners to keep the price down, either -- this is a very capable camera. It has a 6 Megapixel CCD, a large and sharp 2.5" LCD display, full manual controls, an elaborate help system, and the kind of performance that you'd expect from a D-SLR. Did I mention that it's also very compact?
Nikon D40 features:
The 6.1 effective Megapixel Nikon D40 camera body
F3.5 - 5.6, 18 - 55 mm Mk II Nikkor DX zoom lens
EN-EL9 lithium-ion rechargeable battery
Battery charger
Body cap
Eyepiece cap
Shoulder strap
USB cable
CD-ROMs featuring Nikon PictureProject
125 page camera manual (printed)
The D40 is sold with a lens (no body only kit yet), and you'll find a brand new second generation 18 - 55 mm lens. Taking the D40's 1.5X focal length conversion into account, the kit lens has the field-of-view of an 27 - 82.5 mm lens. Overall I was pretty happy with this lens, though it has a bit of a problem with purple fringing. I'll have much more on photo quality later in the review.
The D40 doesn't come with a memory card, so you'll need to pick one up if you don't have one already. The camera supports both SD and the newer SDHC cards, which currently top out at a whopping 8GB. I don't think you need a card quite that large -- I'd start out with 1GB myself. Spending a little more for a high speed card is a good idea.
Nikon came up with a new battery when they created the D40, and it's called the EN-EL9. This battery has 7.4 Wh of energy, which is pretty good these days. How does this translate into battery life? Have a look:
The D40 and its new battery turn in above average battery life numbers. I suppose I should mention my usual list of "gotchas" about proprietary batteries like the EN-EL9. First, they're expensive. Secondly, unlike with cameras that use AA batteries, you can't use an off-the-shelf battery when your rechargeable dies. As you can see in the chart above, there's only one camera in this class that uses AAs.
When it's time to charge the battery just snap it into the included charger. It takes just ninety minutes to fully charge the EN-EL9. This isn't one of those handy chargers that plugs right into the wall -- you must use a power cable.

a review of the Asus Eee PC

Good things come in small packages

The Asus Eee PC challenges many conventional assumptions about mobile computing. The daring, diminutive device combines a svelte subnotebook form factor with a unique Linux software platform and a budget-friendly price—factors that could make this unprecedented product a mainstream marvel. Last week, my colleague Jon described the Eee PC as game-changing: a characterization that we will put to the test in this review.

Tech specs CPU: 900 Mhz Intel Mobile Celeron Video: Intel GMA 900 Display: 7" LCD widescreen at 800x480 Storage: 4GB internal flash OS: Custom Xandros-based Linux RAM: 512MB Optical drive: None Networking: Atheros AR5007EG wireless, 10/100 ethernet

First impressions The most striking characteristic of the Eee PC is its unbelievably small size. At 8.9" x 6.5" x 1.4" and approximately 2.03lb, the Eee delivers serious mobility. When closed, it's approximately the same size as a hardcover book. It's also very easy to tote around while it is open and can be comfortably held in only one hand. The exterior has a glossy, pearl-white finish that picks up fingerprints very easily, but seems a bit more dirt-resistant than the plain white finish of a MacBook. According to Asus, the Eee PC will eventually be available in a range of colors, including pink, green, and black.

The Eee battery is a round module that fits into the back underneath the screen between the two hinges. The battery fits tightly with no wiggling and can be removed by sliding two clasps simultaneously. The hinges for the lid are very big and seem sufficiently sturdy. The screen, which takes up only part of the lid, is flanked by two large speakers and is surrounded by a wide bezel. The 4GB Eee has an embedded 0.3 megapixel video camera which is built into the bezel above the screen.

The Eee has several vents on the bottom and one on the side. A panel on the bottom can be removed to provide access to the Eee's RAM, but opening the panel voids the warranty. Intrepid modders have already successfully replaced the built-in 512MB stick with 1GB.

When running, the Eee generates very little fan noise. After several hours of use, the machine gets very warm but can still be used comfortably on a lap. The Eee has a row of LEDs along the front-right side that indicate battery status, drive access, and wireless connectivity.

Dell Inspiron e1705 Review
An important note on the e1705 is the fact that the Dell Inspiron 9400 sold via the Dell Business site is the same notebook as the e1705 offered through the Dell Home online store. The only difference is that the Dell e1705 offers Windows Media Center Edition as an OS, along with an external USB TV Tuner option. Prices and offers may vary between each Dell online purchase channel, so you'd be wise to configure and price similar notebooks on each site to see what the better deal is at the time you order.

Sony VAIO VGN-T140P/L Notebook Review

Features and Specs
Intel's newest Pentium M ultra-low voltage line of chips, packaged with the 'Centrino' integrated wireless
architecture, finally enabled laptop manufacturers to make viable ultra-portable systems based on the Pentium 4 CPU.
The Pentium M's tiny profile and better performance/power usage ratio has brought the world of tiny laptops much
closer to the mainstream.
The VAIO VGN-T140P/L sports a 1.10GHz Pentium M '733' Ultra low voltage processor. Based on a 90nm process, this
chip uses a 400Mhz FSB and like all 90nm process Pentium M chips, comes equipped with 2MB of level 2 cache memory.
The Pentium M is the fastest currently available in Intel's 'ultra low voltage' mobile line and should provide
plenty of grunt for this tiny laptop.
Like other Pentium M processors, the clock speed does not truly indicate the amount of work it can do relative to
traditional desktop processors, so don't let that scare you off. The Pentium M is the reason that Intel decided to
drop the Gigahertz measurements from its processors and switched to a meaningless 'Performance Rating' figure
instead.
The Intel 855GME chipset provides connectivity with the Centrino architecture. The ICH4-M Southbridge handles the
integrated video courtesy of Intel's Extreme Graphics 2 chip, and a fairly standard array of I/O abilities which
we'll detail a bit later. As you would expect, it also supports a good set of power saving abilities which work in
concert with the processor to save precious battery life, typically by dropping processing speed down substantially
when on batteries. More on this later also.
The VAIO notebook ships with 512MB of DDR memory, 64MB of which is shared with the onboard video. The memory can be
expanded up to 1GB in total, though there is only one SODIMM socket. A smallish 4200RPM 40GB hard drive provides
storage. The Intel Extreme Graphics 2 engine provides excellent image quality and DVD playback, along with some
(mostly theoretical) 3D support.
For older 3D games (from a few years ago) it should be adequate, for current games it is extremely poor. This VAIO
is not intended to be a portable gaming machine, so don't even bother trying to use it for that.
The Lithium-Ion battery snaps into the rear of the notebook (model VGP-BPS3), and carries a capacity of 7.4V /
6600mAH. It weighs about 0.66 pounds, and according to Sony figures, will offer a run time of about 4-8.5 hours with
a full charge.

Canon EOS 350D Digital SLR

Category : Digital CameraRating : 4.5 out of 5 stars
The Successor To The EOS 300D
Perhaps the most exciting news that came out of this year's Photo Marketting Association (PMA) is Canon's
announcement of the eight-megapixel EOS 350D, the successor to the hugely popular 6.3-megapixel EOS 300D. The 350D (available in both black and silver versions)
wouldn't be far off from that price point, but now you would be getting even more bang for the buck. A new
generation 8.0-megapixel CMOS sensor is the obvious improvement in the 350D, as well as Canon�s renowned DIGIC II
image processor. Overall speed has been improved too, including a faster startup time, faster continuous shooting
speed (3 FPS), and improved CompactFlash writing speed. One of the main complaints of the 300D was its built quality
and the new 350D significantly improved in this aspect as well. Compared to the 300D, the 350D is lighter, smaller,
and offers a more robust handling (despite its plastic casing). Other additions include nine new custom functions,
selectable metering and AF mode, color space adjustments, custom parameters (for contrast, sharpness, saturation and
color tone), Hi-Speed USB 2.0 connection, a new battery grip, and many others. Such impressive specs are almost
unimaginable a couple of years back.
This review is based on a production unit with firmware version 1.0.1. Standard Package ContentBefore we move on with the detailed aspects of the camera, we list the standard Canon EOS-350D package contents: -Package Contents

Compaq Presario R3000


Compaq Presario R3000 line of Pentium 4 notebooks is a solid performer with good looks and good features. While lacking some of the bells and whistles of other “multimedia friendly” competitors, its minimalist styling is both sleek and functional.


Backed by Compaq's one-year limited hardware warranty, the R3000 series offers a host of configuration options and add-ons. With integrated ATI Radeon 9000 graphics and integrated Broadcom 54G wireless, the R3000 is well-suited for the mobile professional or student who doesn't mind lugging around eight pounds, and the casual gamer who doesn't need the highest settings in the latest games. Its powerful JBL Pro speakers, DVD and CDR/W combo drive and 15.4-inch screen make this an excellent choice for multimedia use as well.


At over eight pounds it certainly isn't the most portable laptop available, but the weight compares favorably to competing products. If you're looking for a sturdy laptop that is somewhere between ultra-portable and a desktop replacement, Compaq's R3000 line, while not being flashy or innovative, is a good choice.

Fujitsu Lifebook T4220 reviews


Fujitsu's latest convertible Tablet takes full advantage of Intel's new Centrino technology, and it shows.

The new Fujitsu LifeBook T4220 is a travel-friendly, well-rounded convertible Tablet PC that suffers from a few flaws. When it comes to computing horsepower and video quality, the newest addition to the LifeBook line reaps the benefits of Intel's Next-Generation Centrino Processor Technology (codenamed Santa Rosa), but its battery life left us wanting more.

Dressed in a sleek black-and-silver finish, the LifeBook T4220 weighs a manageable 4.3 pounds and is 1.5 inches thick, so you can haul it around without putting too much strain on your back or arms. Beneath the black lid sits a crisp 12.1-inch display with a native resolution of 1024 x 768 pixels (an SXGA+ display is also an option). Viewing angles were good all around on this screen, and color representation was superb. If you'll be using this Tablet outdoors, however, you may want to opt for the daylight-readable screen ,as the standard indoor LCD is difficult to read in direct sunlight.

The display is mounted on a bidirectional swivel mechanism, making it easy to twist the screen in either direction and fold it down for use as a Tablet. You flip the lid latch to secure the screen while in Tablet mode. A built-in sensor automatically adjusts the screen image from portrait to landscape mode, depending on the system's orientation.

A recessed stylus holder and a biometric fingerprint reader sit to the left of the screen; the lower bezel holds an LCD indicator panel and five Tablet function buttons, one of which is used to manually rotate image orientation and two of which are user-programmable. The full-sized keyboard is comfortable with well-spaced keys, and the responsive touchpad sports a scroll button and two mouse controls. Although the plastic black-and-white stylus felt kind of chintzy, it got the job done and worked well with the Active Digitizer screen.

Along the front edge of the keyboard deck are headphone and microphone jacks, a 3-in-1 card reader, and a pair of flat-sounding speakers. The left side houses SmartCard and PC Card slots, a USB port, and a Wi-Fi switch, while the right side holds a modular DVD burner. Three USB ports are positioned along the sides of the notebook, as are Ethernet, modem, and VGA ports. Unfortunately, the T4220 lacks a FireWire and S-Video ports. The 120GB hard drive is protected by an anti-shock mounting mechanism and Fujitsu's 3G Shock Sensor, which retracts the drive's read/write head in the event of a sudden bump or accidental drop.

The big news here is Intel's new Centrino architecture and all the features that come along with it, including faster processors, enhanced graphics performance, and 802.11n wireless. Our LifeBook T4220 was equipped with a new 2.2-GHz Core 2 Duo T7500 processor (with a front-side bus speed of 800 MHz) and 2GB of DDR2 memory. The T4220 turned in a very respectable PCMark05 score of 4,259, which means it will handle most business applications with aplomb.

The LifeBook T4220 is based on the new Mobile Intel 965 Express chipset, which provides enhanced video performance courtesy of Intel's GMA X3100 graphics controller and Clear Video Technology. After firing up our Finding Nemo DVD, we were very impressed with the image quality; the movie looked smooth and clean with no noticeable artifacts, and colors seemed to jump off the screen. With a 3DMark03 score of 1,743, the LifeBook will likely struggle with most high-end 3D games but had no problems with Vista's Aero interface.

It's too bad this system doesn't last longer on a charge, however. The LifeBook T4220 conked out after two hours and five minutes on our DVD drain test, which means you should expect about three hours of runtime. This showing was a bit surprising, especially given that Intel's new Dynamic FSB Switching technology is supposed to reduce power consumption and improve battery life by decreasing bus speeds and processor voltage when not needed (such as when playing DVD movies or listening to music). We recommend springing for the $134 six-cell modular-bay battery, which should increase the T4220's endurance to about six hours, according to Fujitsu. Just keep in mind you'll need to pop out the DVD drive to use it.

Also part of the new Centrino platform is Intel's Wireless Wi-Fi Link 4965AGN, an integrated wireless solution that supports draft-n connectivity. The T4220 turned in very good scores of 18.3 and 14.1 Mbps at 15 and 50 feet, respectively, on our Wi-Fi throughput tests. The system comes with Windows Vista Business Edition, but you can order it with Windows XP Tablet PC Edition instead. Be sure to check back once we get a final-production model in.

Despite its underwhelming battery life, the Fujitsu LifeBook T4220 is a solid convertible that gets a sizable performance boost from Intel's newest Centrino processor and graphics technology.

Laptop Battery FAQ


Q How long does a laptop battery last? When should I consider replacing mine?
A All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.


Q How should I choose between two batteries with different Watt hours (Whr) available on one system?
A Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer battery run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.

Q How long am I able to use my laptop on a fully charged battery?
A Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.
Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, "Understanding Battery Life in Portable Computers" is available at:


Q How do I charge my laptop battery?
A The battery charges in the laptop when the laptop is connected to an AC power source via the AC adapter.


Q How long does it take for a laptop battery to fully recharge?
A The charge time varies depending on the system. the battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.


Q Should I totally discharge, then recharge my laptop battery occasionally to make it last longer?
A No, discharging and charging does not increase the life of a Lithium Ion technology battery.


Q Can a laptop battery be "overcharged"?
A No, the battery is designed to stop using the charger when it reaches full charge.

Q When docked or AC adapter is plugged into a wall outlet, am I using my battery charge?
A No.

Q Does laptop has external battery chargers?
A Espow.ca offers a Datamation battery charger for large institution customers. The charger has 16 charge bays to charge batteries for Latitude D500/D505/D510/D520/D600/D610 laptop systems. The product can be found at Dell.com here:


Q Is it easy to install a battery?
A Yes, very easy. First, make sure all open files are saved. Next, either attach the AC adapter directly to the laptop or set the system to "hibernate" mode or shut off. Release the latch on the current battery, and simply install the replacement battery.

2. Don't play computer games, music or DVD movies - Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness - Dimming your display saves battery power.

5. Tweak Windows Power Options - Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use.

10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

How to extend laptop battery life?


How to extend laptop battery life? Here are some more tips to improve your notebook's battery life:

1. If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.


2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.


3. Make sure to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.


4. If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.


5. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.


6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.


7. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
