Apple admits to faulty laptop batteries

Apple today issued a statement saying there are some known problems with MacBook and MacBook Pro notebooks in which the battery might have poor performance, but there are no safety concerns. These performance problems include:
laptop Battery is not recognized causing an "X" to appear in the battery icon in the Finder menu bar laptop Battery will not charge when computer is plugged into AC power. laptop Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300. laptop Battery pack is visibly deformed.Macbook users have been issued with a software update to fix �visibly deformed� battery packs, among other problems
Apple has admitted that some batteries in its Macbook and Macbook Pro line of laptops have �performance issues� and has issued a software update to fix the problem.
Among the symptoms of batteries that are affected are swelling, the battery not being recognised or not charging, and a shorter than expected battery life.
"The factors causing the performance issues do not present a safety risk. You may continue to use your current battery," the company said.
Reports of problems, including swollen batteries, have been circulating since the laptops were launched in 2006.
In its support notes to users, Apple says battery packs which are "visibly deformed" are among the symptoms of battery problems.
The company advises users to install the update on all "MacBook and MacBook Pro computers and extra batteries that were purchased between February 2006 and April 2007".
Apple has a support site up and if your battery experiences any of these symptoms you should download the software to try and correct the problem. If the issues with the battery persist, Apple has a replacement program in place. Information on their site will guide you through this.
Despite the problems, Macbook remains a successful range for Apple. The company recently reported that sales of its portable computers rose from 498,000 to 891,000 over the 12 months to March 31, helping boost quarterly profits to $770 million (£386 million).

Motion Computing releases the smallest tablet PC

Motion Computing releases the smallest tablet PC
Motion Computing releases the LS800 as the smallest tablet PC running Microsoft® Windows® XP Tablet PC Edition 2005.
It has an 8.4-inch display and is less than 1 inch thick weighing 2.2 lbs. It uses the Intel Pentium® M Processor Ultra Low Voltage 753 (1.2 GHz) and the Mobile Intel® 915GMS Express Chipset. The LS800 uses the 1.8" hard drive vs the typical 2.5" you see in notebooks usually. Also, it's protected by a plated carbon-fiber chassis with metalized paint.
�The LE1600 builds upon Motion�s history of offering best-in-class slate tablet PC design for an unsurpassed mobile computing experience,� said Scott Eckert, Motion Computing�s CEO. �After listening to our customers in the mobile workforce, we have enhanced nearly every component, feature and design element in the LE1600 to increase productivity for on-the-go users while providing enhancements in mobility, performance and security. Through our leadership in product innovation, as well as our build-to-order manufacturing model, Motion is well-positioned to increase its already-significant share of the worldwide tablet PC market.�
Tablet PCs were touted by companies such as Microsoft as the future of mobile computing when products were first released in 2002. Tablets resemble notebooks but allow users to enter information on a touch-sensitive screen and to hand-write notes into certain applications. To date, shipments of the devices only represent a small fraction of the notebook PC market, according to industry market researchers. Certain industries, such as education, health care, and insurance, have shown a special interest in Tablet PCs, Clark said.
For the most part, the portable PCs have been released in two different categories. Slate devices, such as Motion's products, consist of a flat slab that lacks a keyboard. Convertible devices, released by companies such as Hewlett-Packard and Toshiba, resemble conventional notebook PCs but have a flexible screen that rotates to cover the keyboard when used in Tablet mode.
Motion is now trying to get more PC users to recognize the benefits of a Tablet PC, such as its lightweight design and its capacity for around seven hours of computing time, with an optional second battery, Clark said. Other companies are trying to lower the price of their Tablet PCs to the level of mainstream notebooks.
Most Feature-Rich Tablet Available Today
Motion�s LE1700 is packed with cutting-edge features and technologies; all in a lightweight, durable and ergonomic slate tablet PC.
The LE1700WT includes the exclusive Motion WriteTouch display option for the most responsive dual-mode writing and touch-screen experience on the market. With the LE1700WT, Motion is the first to bring to market automatic switching between digitiser and touch input with a simple double-tap of a finger or hover with the digitised pen to go from one mode to the other. WriteTouch accepts input from the pad of a finger or digitised pen, but will not respond to other materials or objects.
�N-trig�s native dual mode technology for pen and capacitive touch enables the LE1700 to set a new and superior standard for tablet usability and natural input,� said Amihai BenDavid, CEO, N-trig Inc. �This new technology expands the horizon for mobile computing where even the most experienced tablet users will find a dramatic change in how they interface with their system. Once again, Motion is demonstrating its vision and leadership through introduction of the LE1700 for tablet PC users.�
Optimized by the tablet PC enhancements included in the Microsoft Windows Vista operating system, the LE1700 will allow IT departments to use one operating system across all enterprise hardware. Vista includes additional layers of .NET integration to facilitate the development of digital ink applications. Finally, with Vista, the handwriting experience is improved for the user with a trainable Tablet Input Panel (TIP) that personalises handwriting recognition.
�The LE1700 provides the enhanced computing experience mobile professionals expect,� said Bill Mitchell, corporate vice president of Microsoft�s Mobile Platforms Division. �Motion�s display innovations and ergonomic product design uniquely take advantage of the tablet PC and mobile computing benefits in Windows Vista.�
The LE1700 is the first slate tablet PC on the market to offer Intel�s Core 2 Duo technology for greater than twice the CPU performance when compared to the previous generation Intel® Centrino®. Core 2 Duo increases system responsiveness when running multiple applications and extends mobility with smart battery power management.

Fujitsu just returned from exile with a claim to the biggest fastest laptop

Fujitsu just returned from exile with a claim to the biggest fastest laptop-disk throne. The 3Gbps SATA-equipped MHZ2 BJ series measures in at a standard 9.5-mm and spins at 7,200rpm with a 16MB cache and 25dB idle noise level. Average seek times are listed at 10.5-ms for data reads and 12.5-ms for writes while drawing 2.3 watts of power. Oh sure, a disk drives have already been announced. But most of those measure in at a non-standard 12.5-mm making them unsuitable for the majority of laptops on the market today. Sales of the new MHZ2 BJ-series begins in June.

Toshiba unveils laptop batteries which can charge 90% in 10 minutes

Toshiba, one of the leading manufacturers of portable computer systems, has demonstrated a SCiB battery designed for laptops, at this year's CEATEC exhibition, taking place in Japan between September 30 and October 4. The showcased battery is said to be capable of recharging up to 90% of its capacity within just 10 minutes

When you think of a laptop, the last thing you would expect to excite you would be a laptop battery, unless of course you run out of juice and are nowhere near an outlet. At the recent CEATEC exhibition over in Chiba, Japan, Toshiba is showcasing a type of laptop battery that is currently being used in industrial applications, but could make long laptop recharges a thing of the past.

They are called Super Charge Ion Batteries or SCiBs for short, and have been around for a year in industrial use. But now, a laptop prototype battery, presented by Toshiba, is being showcased that features recharge rates of 90% in only ten minutes. Turns out fast recharges aren’t the only benefit, however. It seems SCiBs are also made for the long haul. Compared to typical lithium-ion batteries that will last for around 500 cycles before needing a replacements, SCiBs last 10 times longer by lasting up to 5,000 to 6,000 recharge cycles.

According to Toshiharu Watanabe of Toshiba, the "excellent performance of the SCIB will assure its successful application in industrial systems and in the electronic vehicles markets as a new energy solution". Indeed, the long-awaited Schwinn Tailwind electric bicycle will reportedly feature a SCIB battery that charges in less than 30 minutes.

this check list may save you much frustration when buying a laptop.

If you are planning to purchase a secondhand laptop then this check list may save you much frustration. We are now seeing many secondhand laptops coming onto the market. Many of them at prices which make them most attractive as a second machine. These notes are intended as a checklist to help you avoid the proverbial lemon.
Laptop PCs may be offered for sale privately by the original owners or by dealers who have sourced a number of them from large companies. Large companies might typically update their employees' laptops after a couple of years because the units were either under lease, out of warranty or it was cheaper to purchase new laptops rather than upgrade the software to operate with the latest company office network. Buying privately is attractive, as the owner should be able to provide the original manuals and software. Buying from a reputable dealer should ensure that you get some sort of guarantee if it should fail.
Whatever the reason for the sale, there are many useful laptops available and yes there is probably a number with a problem that the previous owner is not prepared to live with, or fix.
Many of the points are self evident but to miss them beforehand might be most annoying, if not expensive later. As with any product, an honest seller with nothing to hide should not object to your giving the PC a good work over, as it should do no harm and won't even wear the tyres from a spirited test run!
Here’s a whole checklist of quick, fast facts you might want to consider before you buy your next computer. Some are very common basic computer facts you probably already know; while others deal with more recent technologies and products that you should check or be aware of when buying your new computer.
What Type of laptop? What processor: a 386, 486, Celeron, Pentium etc? As with the desktop PC the newer the processor usually the faster and better the performance, but note that contemporary tests of many laptops showed surprising differences in operating performance benchmarks among units of apparently similar specifications. A 386 may be useful for simple word processing under Win3.1, but typically such a machine would be inadequate to run WIN9x and its battery would probably be only a Nickel Cadmium (NiCd) with a shorter life compared with later battery technologies. Also early screen displays may be difficult to read in bright surroundings. A 486 with say at least 16 MB RAM could run Win9x. Later models have a faster processor that consumes more power so don't necessarily expect battery life to be far longer on the newer models. If you only want to do minor editing of documents and don't need massive processing power then a simple 486 or Pentium 100 with a couple of spare batteries and car adaptor might be ideal. Conversely if you want to listen to CDs, watch movies or demonstrate software then at least a 400 MHz (or better) processor will probably be necessary. Some laptops operate at a lower speed when running on battery to extend the battery life so be aware that performance benchmarks could vary between running on mains power or battery.
How Much RAM? Random Access Memory is temporary memory your computer uses to run applications and data on your operating system. Generally the more RAM you have, the faster your computer will run. You need at least 256MB for Windows XP and Mac OS X. You need at least 1 Gig of RAM for Windows Vista but 2 Gigs or more will make it run smoother. However, 32-bit Operating Systems ONLY recognizes up to 3GB of RAM, while you need 64-bit systems to take full advantage of 4GB of RAM.
Extended Warranty?Many manufacturers and retail stores will try to sell you extended warranties on any computer system you're considering. These warranties can be expensive so it is up to the individual buyer whether or not to purchase them. It will depend upon your own resources but if you're buying an expensive unit going with an extended warranty is a real option - especially when you consider replacement costs and the "peace of mind" such things supposedly brings.

How to do better for more laptop battery life.

For a laptop battery user, we should know Laptop Battery Basics :Take care of your laptop battery and ensure that it will be ready to work properly when you need it most. Some general tips for laptop care include: avoid extreme temperatures, don't leave a laptop outside in cold weather or leave it in a hot car. Cold batteries can't create very much power and hot batteries will discharge very quickly. Use electrical power when available to keep battery charged. Don't let your laptop go for long periods of time without using the battery.Ni-Cad (Nickel Cadmium battery), and Ni-MH (Nickel Metal Hydride) were once highly used having 1.2 Volts per cell.Li-Ion (Lithium-ion) have now taken their place having 3.6-3.7 Volts per cell and are much more practical for today's power hungry notebooks. They have more power, higher voltage, less self drain, less weight, and can be smaller for the power you get. You will also not find the memory problems previous batteries were known for. I guess the only drawback is they're more expensive.Smart/dumb batteriesYou will find most if not all of today's notebooks use Li-Ion smart batteries. The fact that it's smart means it has circuits that report its charge level so you can estimate the battery life remaining or when it's about to run out.Batteries are over-all measured in "mAh" (Milliamps/hour) There are many things you can do to increase your battery life at the cost of performance, comfort, and features. What many will do that need to maximize their battery life for example if they're going on a trip, is get their settings in order before heading out. Here's a few things you can do:Adjust LCD brightnessMost notebooks will be set to dim the LCD automatically by default from the factory. Unplug your system to check the brightness to verify. Some will do it over a few seconds slowly so you don't notice it so you have to watch carefully. If you feel you could deal with the display being even more dimmed, then (Windows) right click your desktop background, go to "Properties", then click the "Settings" tab at the top. Click "Advanced" and you will often find your settings for brightness in there which can vary depending on the graphics chipset and software on your system. Sometimes you can find the graphics control panel or settings hot link in your lower right hand system tray depending on software.Turn it down to whatever you're comfortable with. The LCD is one of the biggest battery hogs most laptops face keeping fed.
