Sony's Transmeta: Longer Life, Less Performance

What business traveler wouldn't want a notebook with double the normal aspire 1300 battery life? That's Transmeta's promise, and the first taker becomes available in late October: a new edition of Sony's VAIO PictureBook.
Naturally, more than a few mobile computer users took notice when Transmeta promised a battery-friendly notebook processor that would dramatically increase the run time between recharges while offering Intel-comparable performance. (See "Transmeta Unveils Crusoe Chip.") PCWorld.com's tests show that some of Transmeta's battery-life claims stand up. But be prepared to pay a hefty performance penalty.
Not Quite Picture PerfectIn our btp-43d1 battery tests of the preproduction PictureBook PCG-C1VN, the unit lasted two hours and 32 minutes, which is 50 minutes longer than one of Sony's most recent PictureBooks, the PCG-C1XS, which we tested for comparison.
The new $2299 Sony PictureBook we tested came with a 600-MHz Crusoe TM5600 btp-58a1 processor, 128MB of SDRAM, and Windows Me. It also had a 12GB hard drive, an 8.9-inch active-matrix display with 8MB of graphics memory, a built-in 56-kbps modem, a built-in camera, and both Memory Stick and PC Card slots.
The comparison unit had a similar configuration, save for its Pentium II-400 CPU, 64MB of memory, and 2.5MB of graphics memory. For a closer comparison, we upgraded the PCG-C1XS from Windows 98 SE to Windows Me before testing.
Though btp-63d1 battery life didn't double, most serious mobile users wouldn't sneeze at the extra 50 minutes. And overall, 2.5 hours is a good travelmate 290 battery life span for this class of product.
But at what cost? Mininotebooks traditionally score poorly on performance tests, so we didn't expect the new PictureBook to break any PC WorldBench 2000 records. Still, its score of 66 is shockingly low. Even with half the memory of the Transmeta unit, the older Pentium II-based PictureBook scored an 81, so you're losing a noticeable 19 percent in performance (maybe even more, since the older unit would probably perform better with equivalent memory).
Given that mininotebook users don't typically demand the highest levels of performance, some may not care about the loss. During simple hands-on testing, the Crusoe-based PictureBook easily handled basic chores such as word processing. It did slow noticeably during some video-editing tasks, however.
Fujitsu, Hitachi, IBM, and NEC have announced plans to ship notebooks travelmate 4000 battery with Transmeta's chip, but none has given a definitive date for a U.S. launch. (See "Transmeta, AMD Show Battery-Friendly Notes.")
Transmeta's Trade-OffsUnlike Intel's and AMD's mobile chips, which are x86 processors that do all of their work in hardware, Transmeta's Crusoe uses code-morphing software to change x86 instructions into language it understands. Shifting the instruction work from hardware to software affects performance but lets Transmeta build a smaller chip that uses less power and generates less heat. That economy combines with Transmeta's LongRun technology, which shifts the chip into low or high speed and voltage depending on program needs. The result is a more power-efficient CPU. (See "Intel's Travails: Once and Future Notebook King?")
For some consumers, the improved travelmate 2300 battery life will be worth the loss in performance. And future products based on Transmeta chips may lessen the performance hit and make the new devices more appealing to those who need a bit more speed from their systems.
As for the sharp-looking PictureBook, it offers a lot to people who need a very mobile package. It weighs just over 2 pounds (including its groovy built-in camera) and comes with both video- and photo-editing applications. If top performance isn't an issue, it may just suit your needs.

Nikon Coolpix 5000

The Coolpix 5000 is a versatile, powerful 5-megapixel camera in a remarkably compact case. Though small enough to fit into a large field coat or pants pocket, it has nearly all the controls a serious photographer would look for. Thanks to its light weight and large right-handed grip, this unit is more comfortable to hold and operate than its 5-megapixel competitors. Its overall appearance doesn't depart radically from that of other small, boxy digital cameras, but the 5000's look and layout are refreshingly new for a Coolpix. One distinctive change is the adaptable rotating color LCD panel. Fold it face-in to protect it from bumps and scratches. Pull it from the body, and it swings out horizontally 180 degrees (a bit like the fold-out viewfinders you see on digital video cameras). From there you can rotate the LCD up and over so that it faces the same direction as the lens (great for self-portraits) or down so that it faces the ground (useful for overhead shots). Spin the panel 180 degrees and fold it back into the camera, and the LCD faces out--as on a typical digital camera. The Coolpix 5000 is not the first camera to pull this trick--Canon's G1 and G2 got there first--but it's a valuable addition to Nikon's bag of tricks. In most cases, we had no trouble changing the Coolpix 5000's settings. A good-size thumb dial on the top right corner of the camera lets you efficiently select an aperture or shutter speed; a button-and-dial combination steers you through the usual exposure controls (automatic, aperture priority, shutter priority, and manual). Using other buttons, you can quickly change frequently needed settings, such as focus mode, resolution, flash, and exposure value. A strategically placed button on the front of the camera, close to the lens, lets you quickly lock the exposure and focus for multiple shots--an extremely useful feature for shooting panoramas.Our biggest gripe with the Coolpix 5000 is its hair-trigger shutter. You'll be glad that deleting unwanted shots is relatively easy because you're likely to take a bunch--especially at the start. Another flaw involves the small monochrome LCD status panel to the right of the optical viewfinder. In aperture- or shutter-priority modes, it lists the setting you've dialed in, such as the f-stop in aperture-priority mode, but not the reciprocal setting that the camera picks (the shutter speed, in the case of aperture priority). To get this often vital information, you have to turn on the color LCD display, which shortens battery life. We wish the LCD were brighter, too: For properly framing close-ups you almost have to use the LCD. But when we tried taking outdoor wildflower shots in bright sunlight, we could barely see the image. And you can't attach the Coolpix 5000's lens cap unless the camera is turned off. That's inconvenient on damp or dusty shoots.In our standardized tests, the Coolpix 5000 earned an overall image quality score of very good. As you'd expect from this class of digital camera, the Coolpix produced sharp, detailed, and (for the most part) accurately exposed images. Our test prints had a little too much contrast, however, resulting in some loss of shadow details. We also noted some mottling in the blue sky of our test outdoor shot. Taking informal shots, we created pleasing close-ups with bright colors and accurate focus. Impromptu flash photos of people were satisfactory, with relatively accurate skin tones and little flaring from the flash. On the other hand, scenic shots of our local green hills looked rather dull. When we first picked up the Coolpix, its controls seemed unintuitive; but given some time, we adapted to them nicely. The buttons are small but functional, and reasonably well placed. You can hold the camera and change basic settings such as resolution, flash, and macro mode with one hand. Unfortunately, a few controls, are extremely awkward. Case in point: To set the focus manually, you have to hold the small auto-focus button down with your left thumb and spin the selector dial with your right thumb; there is just no comportable way to position your left hand during this operation. The foldout LCD panel has three buttons embedded in its frame: One turns the LCD on and off, another pops up the menus, and a third lets you quickly review stored shots. When you view the LCD folded out, the buttons are at the top of the frame; in that position they're a bit difficult to use. With the LCD folded against the back of the camera, the buttons are situated at the bottom of the frame; and braced by the camera, they're easier to push. Powered by a proprietary lithium-ion rechargeable battery, our Coolpix 5000 recorded an impressive 332 shots on one charge. The kit includes an external battery charger with an AC adapter. Unfortunately, the AC adapter cannot be used to power the camera directly (you have to buy a second, optional adapter), and if you're out in the field for an extended photo shoot, you'll likely want a second battery ($40 to $60). Options for the Coolpix 5000 include a solid selection of accessory lenses--among them, a fish-eye wide-angle lens. Nikon bundles a fairly useful collection of software with the Coolpix 5000. Nikon's View 4 is a handy and simple utility for viewing and downloading images from your camera. The software CD-ROM we received also had a demo of Canto's sophisticated Cumulus 5.0 image management software and Altamiura Group's popular Genuine Fractals 2.0 LE digital image enlarger. A good bet for sophisticated photographers looking for a powerful, light digital camera, the Coolpix 5000 is a fine digital companion for people still attached to their 35mm film SLRs.pa3107u-1brs ,pa3383u-1brs , pa3384u-1brs , pa3285u-1brs , pa3191u-1brs , pa3166u-1brs,pa3356u-1brs ,pa3291u-1brs

Sony runs Walkman off sugar-based bio battery

A year ago it seemed Sony Corp. couldn't even get a laptop battery right. A massive recall of lithium-ion cells tainted its image and had the company scrambling, but on Thursday it reported a sweet breakthrough in bio battery technology.
Sony, one of the world's largest battery makers, said it had succeeded in creating a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 millimeters cubed, delivers 50mW (milliWatts) -- a world record for such a cell, according to the company.
A video provided by Sony shows four of the cells connected in series delivering enough energy to power a Walkman music player. The battery uses glucose solution as a fuel. A second video shows a small fan being powered by the cell with a glucose-based sports drink used as the fuel.
As in other cells, power is produced through a flow of electrons between a cathode and anode.
In the bio cell sugar-digesting enzymes at the anode extract electrons and hydrogen ions from the glucose. The hydrogen ions pass through a membrane separator to the cathode where they absorb oxygen from the air to produce water as a byproduct. The electrons flow around the circuit outside the device producing the electricity needed to power it.
Details of the bio battery were accepted as a paper at the 234th American Chemical Society National Meeting and Exposition that is taking place this week in Boston.
Sugar is naturally occurring so the technology could be the basis for an ecologically-friendly energy source. Companies like Sony are researching numerous technologies that could replace the dominant lithium ion cells as a clean power source for portable electronics.
One of the most talked about is fuel cell technology. While hydrogen-based cells have taken off for home or automobile use, versions based on methanol for use in electronics products have yet to be commercialized. Toshiba Corp. and NEC Corp. are among the companies that promised methanol fuel cell-based laptops in previous years, but each time technology launches have been delayed.

Sanyo, Lenovo to share cost of battery recall

Japanese electronics company Sanyo Electric Co. Ltd. and computer vendor Lenovo Group Ltd. are discussing how to pay for the recall of over 200,000 laptop PC batteries, but have agreed to share the burden.
"We are discussing the recall with Lenovo right now," said Akihiko Oiwa, a spokesman for Sanyo. Raymond Gorman, a spokesman for Lenovo, confirmed that the companies will share the cost but declined to disclose details of the plan.
The companies have determined that the battery packs suffer from a faulty design, but they are not immediately dangerous unless they have been dropped or otherwise damaged, he said. The companies are recalling the batteries to ensure the safety of users, who could end up with overheating or smoking laptop batteries.
The recall is unrelated to the manufacturing problem that left metal shards inside battery cells made by Sony Corp and caused some to overheat and catch fire. Sony's troubles could lead to the recall of as many as 9.6 million batteries and cost the company an estimated ¥51.2 billion (US$433.5 million).
Oiwa declined to comment on how much the latest recall might cost Sanyo or Lenovo.
The recall affects batter packs sold by Lenovo as an option on certain versions of ThinkPad notebook PCs in the R series, T series and Z series model lines. The faulty packs have the part number FRU P/N FRU 92P1131, FRU 92P1141, ThinkPad T40,ThinkPad T43,ThinkPad R40,ThinkPad T6092P1101, 08K8214,40Y6799.
