laptop battery news

We did get a kick out of the bundled voice recognition software: we commanded it give us the weather in New York and it brought up a weather map within a few seconds. We almost wrote this paragraph without complaining about any preloaded software at all, but that was until ASUS’ preloaded screen saver started up with hold-type music in the background. Seriously — remove this crap before you do anything else with this laptop.

In addition, together with partners from public services, RWE is driving the comprehensive expansion of a charging infrastructure forward. RWE’s goal is flexible “refuelling” wherever cars are parked anyway – at home, work or on a shopping trip. This is how electric driving will become suitable for everyday use.

Then there’s the overall design, which is leaps and bounds (in my opinion) above the competition. Though the round touchpad might not attract everyone, the UC7807u delivers a great-looking face and sweet keyboard, along with the cool touch button media controls. Even the hinge looks nice, in all its brushed aluminum glory.

Unlike SYSmark, PCMark is more of a synthetic benchmark, as very little is seen to the user during the run. However, each test tackles a specific and common scenario that’s typical of many computer users – enthusiasts and regular users alike – such as photo manipulation, gaming, music conversion, productivity, et cetera.

For the most part, I found games to almost work better here than on a desktop… especially games like H.A.W.X, which was completely fluid and usually kept a 50 – 60 average FPS. Overall, this has got to be the ultimate LAN party notebook, without question. It also costs nowhere near as much as a comparable Alienware offering, and while it doesn’t look as cool, it certainly delivers the performance hardcore gamers are looking for.

Toshiba backs the R10 with a three-year parts-and-labor warranty (the laptop battery is covered for one year), which includes carry-in support at authorized service providers throughout the country such as UPS Stores and Mail Boxes Etc. locations.

When time allows, I’d like to start adding a small feature to each notebook review stating Linux support, since I do use the OS quite heavily, especially on notebooks . Being that the CPU found here is brand-new, I didn’t expect the best support out there, but I was rather surprised. However, for some reason the latest version of Ubuntu (9.04) would not boot, so rather than taking the time to trouble-shoot, I tried 8.04 instead, and I had much better luck there.

Our tested configuration came loaded with Windows Vista Business (though you can opt for an XP Pro downgrade) and trial versions of Microsoft Office and Norton Internet Security. Toshiba also took the liberty of installing Google Desktop and Picasa 2 on the system, as well as its own DVD player, which is a good thing, since the other two DVD-player apps loaded with Vista didn’t seem to have the right codecs to play DVDs out of the box. The company backs the R600 with a generous three-year warranty.

2009 has been a busy year for Massachusetts-based battery maker A123 Systems. Having already landed a contract to supply Chrysler with lithium ion batteries, received nearly $250 million in grant money from the U.S. Gov’t, and launched a public stock offering; A123 Systems is now capping off this calendar year with the announcement that they’re entering into a joint venture with SAIC Motor Co. Ltd, a leading automaker in China.

The purpose of the new venture will be to make and supply batteries for hybrid and all-electric cars and trucks in China, which is currently the largest and fastest growing automotive market in the world. The venture’s ownership will be held 51 percent by SAIC Motor and 49 percent by A123 Systems, with the management duties of the venture being shared equally between the parties.

“We are excited to be partnering with an industry leader such as SAIC Motor to pursue the expanding Chinese market for advanced lithium ion battery technology,” said David Vieau, chief executive officer of A123 Systems. “As part of this partnership we look forward to building a team of outstanding employees to develop innovative battery technologies that we expect will be included in some of the highest quality hybrid and electric vehicles anywhere in the world.”

Since first going public back in September, A123’s stock has steadily declined. However, news of the deal apparently has investors reinvigorated as the stock has been rising again and could soon be back to where the company was priced when it was first released to the public.

Choosing the best laptop microphone can be an easy decision by first considering a few things. Since there are many sizes and styles available that can achieve different results, the most suitable laptop microphone will typically depend on how it connects to the laptop, its intended use, and the sound playback quality that is desired. Whether the laptop microphone will be used simply for online communication, or for music, gaming, and voice recording is an important factor to consider. Knowing a few technical aspects of the laptop microphone should help make the deciding process an easier one.

Though some laptops may have a built-in microphone, a stand-alone laptop microphone will typically provide higher-quality sound playback. There are many options available, including headset-style microphones, free-standing microphones, pocket-sized microphones, and a range of other styles to suit specific needs. A headset microphone might be a good choice for online voice communication, for voice recognition computer software, or to record vocal tracks with less background noise interference. Stationary and handheld laptop microphones might be used to record a single musical instrument, a group of musicians, or even a live concert. Most compact microphones usually connect through the laptop’s microphone port, and may an ideal choice for online communication via voice chat, unless a built-in microphone is to be used.

If the laptop microphone is to be used for talking over the Internet or used with voice-recognition software, sound quality may not be much of an issue. For those who wish to record music, voice, or instruments with a laptop microphone, it will be much more important to find one that offers high-fidelity sound playback. Although many microphone brands may claim to offer high-quality sound reproduction, few will likely meet expectations, making it difficult for some consumers to discern one from another in terms of quality. To know what sort of sound quality to expect from a certain microphone, one should be familiar with some technical aspects.

Knowing a few microphone-related terms such as uni- and omni-directional, frequency response, and noise canceling, will help ensure a wise investment. An unidirectional microphone records sound that is emitted from one specific direction, while an omni-directional microphone will pick up sounds from virtually all directions. Frequency response refers to the range of high and low tones a particular microphone is capable of receiving, and is expressed in Hertz (Hz). The Hz rating of the microphone will determine how uniform the recording playback will sound, and the range of tones that will be picked up. Microphones which offer noise-cancellation will help diminish the amount of background/ambient noise that is captured when in use, and may be a suitable choice for music or voice recording in high-noise environments, and a good microphone for the professional or studio musician.

In what is now the second recall to take place within the past week, the P.C. manufacturer Fujitsu has voluntarily issued a recall of batteries from its Amilo P range of notebooks.

Citing ‘a limited number of customer reports about overheating batteries and an associated fire risk’, Fujitsu has gone ahead and set up a free battery exchange program for selected AMILO notebook models sold between April 2007 and June 2009. The batteries in question are lithium-ion and will be immediately replaced by the company. Fujitsu stressed that no other laptops are affected by the battery recall.

A recent article on Yahoo caused a bit of stir with its point of view that the PS3 remote control battery configuration makes the PS3 a questionable christmas gift. The article, A Grinch’s Gift Guide, cited the hefty price tag of a replacement remote will cause headaches once the remote’s battery runs dry-

“It’s all fun and games until the battery dies. Unlike its competitors, which use replaceable AA batteries, the PS3’s remote control is glued shut. When the battery goes, Sony customers have to blow $55 on a new controller. Sony says there’s an “environmental benefit” since gamers don’t have to toss their batteries on a regular basis, but Isidor Buchmann, president of battery-equipment maker Cadex Electronics, says captive batteries are becoming common because it’s cheaper for companies to eliminate the battery housing and hatch.”

True, paying $55 for a PS3 remote control isn’t something any PS3 owner looks forward to doing. However, the battery set-up on the remotes isn’t quite as troublesome as the article makes it out to be. The battery is recharged via USB, and it takes quite a bit of use for the PS3 remote battery to run completely dry and become unchargeable. As bingegamer notes, even if you somehow lose your USB cable, you can buy a replacement for $3 at Best Buy. Also, while it may not be as easy as popping out a couple of AA’s, the PS3 controller can in fact be replaced by users.

Battery hens are laying hens who are confined in battery cages for the duration of their short lives. A number of factors combine to make the battery cage environment extremely uncomfortable for such hens, and some animal rights organizations have vigorously protested the practice of keeping hens in such cages. Most eggs in the market are produced by battery hens, unless the packaging on the carton explicitly states otherwise.

The earliest version of the battery cage was developed around the 1930s, and it quickly became a runaway success in the poultry industry. Several things distinguish a battery cage, also known as a laying cage. The first is the slanted floor, which is designed to allow eggs to roll out of the cage and onto a collecting conveyor belt. The cage is typically also all wire, allowing droppings and feathers to fall through the floor of the cage and onto another moving conveyor belt.

Food and water are delivered to battery hens using large conveyor systems, which deliver set amounts at specific intervals. Depending on the farming practices being used, the food may be supplemented with antibiotics to forestall infection, a common problem in battery hens, and the food may also be amended with vitamins and minerals in an attempt to get the hens to produce more eggs.

Perhaps the most distinctive feature of the battery cage is the size. Most battery cages are barely larger than the hens they contain, and in many instances, hens are unable to move or turn around. Typically, battery hens are installed in battery cages within weeks of hatching, and they spend around nine months in cages before being disposed of because they are no longer productive.

Like many animals, chickens can develop some curious responses to stress. Many battery hens, for example, will attempt to attack each other through the wire. As a result, most commercial egg producer debeak their battery hens periodically, removing their beaks with a heated knife so that they cannot attack each other. The hens may also throw themselves against the bars of the cage or wedge body parts into the wire, in some cases severely injuring or killing themselves.

Several nations around the world ban the practice of keeping hens in laying cages, under the argument that it is inhumane. It may also be unhealthy; confined conditions are a breeding ground for bacteria, which can be transmitted through the eggs of the battery hens to human consumers. Such bans can sometimes be disingenuous, as they do not ban caging outright, but rather the practice of using extremely small cages. Many animal welfare groups would like to see free range farming adopted as a universal practice, allowing chickens to live more natural lives outdoors, rather than being confined.

There are three different types of laptop bags: backpacks, briefcases, and slim portfolios. All these types of laptop bags offer the same basic functions; they are designed to hold at least one laptop and power cable. Different types of bags are designed for different functions and it is best to review all the options before making your selection.

Backpack-style laptop bags are designed with the frequent laptop user in mind. Very popular with students, information technology professionals and travelers, this type of bag is ergonomically designed to reduce strain on the back and neck. The trend in laptops is toward smaller and lighter units to increase usage and to meet user’s needs.

A laptop backpack has the capacity for one laptop in a specially designed pocket within the body of the backpack. There are often built-in security ties to hold the laptop in place, so that even if the bag is dropped, the laptop remains secured. Space and pockets for a power cable and battery, traveling mouse and other laptop accessories is available in these types of bags. There is also room for other materials, such as textbooks, notepads, lunch, and other necessities. This type of bag comes with several front and side pockets to increase the capacity and access to frequently used items.

A laptop briefcase has the benefit of presenting a more professional look than a backpack. This type of bag has space for one laptop, a power cable, and a limited amount of other materials. They are usually made of leather or vinyl and offer a shoulder strap as well as small handles. Specially designed airport laptop briefcases allow the x-ray machine to look through the bag. This feature removes the need to take the laptop out of the bag for screening when traveling by airplane.

Slim portfolio laptop bags provide a snug fit that reduces the bulk of other laptop bags. Each model is designed for a specific laptop size. They come in a wide range of colors and styles. Portfolio laptop bags provide minimal protective padding, limited space for carrying accessories and often use a zippered closure which can damage the finish of the laptop. These bags are designed for short-term use and are inexpensive, allowing users to change them frequently or purchase multiple laptop bags.

When selecting a laptop bag, it is important to consider how you use your laptop, the climate, and locations that you will be working in. A poorly designed laptop bag can cause back, neck, arms and shoulder strain. Investing in a quality laptop bag is well worth the cost.

Laptop accessories are additional items that can be used to enhance the performance of a laptop computer, improve user experience, or assist in the protection of the laptop. A laptop is a computer that has a built-in keyboard and a folding screen. Laptops vary widely in size, thickness, and weight and provide computer users the ability to work in a wide range of locations.

Accessories designed to improve the laptop performance focus on core laptop functions. All laptop computers have a built-in rechargeable battery. The capacity and lifespan of the battery varies by model and manufacturer. External rechargeable battery units are a popular laptop accessory, as they provide increased battery life.

Car and airplane charger accessories allow the laptop to accept power from the lighter outlet in a car and the power outlet in an airplane. Cooling mats are placed under the laptop to shield the user from the heat generation from the laptop battery and to reduce the radiation that may be emitted from certain types of laptops.

Tools that improve the user experience include a mobile computer mouse that is connected by a USB key, headphones, microphones, and mobile technology. Docking stations are base units that provide a central connection to power, network connectors, monitor, keyboard, and mouse. The laptop is placed inside the station and pins in the back of the unit lock into the docking station. All the accessories are connected to the docking station itself, providing a simple, quick method of converting a portable computer into a desktop model.

Laptop bags are necessary to protect the laptop while traveling. These bags come in a wide range of shapes, styles, and colors. They are all designed to protect the laptop, provide an easy method of transporting the laptop, and have holding space for laptop cables and other laptop accessories. Laptop bags are available as backpacks, briefcases, portfolios, and simply carrying cases.

For users who are in wet or dusty working conditions, there are laptop accessories designed to protect the unit from these elements. Specially designed cases made from rubber and plastic materials are used to protect the laptop if it is dropped, exposed to water, dust, or dirt. When selecting laptop accessories, it is important to confirm that they are compatible with your laptop. Due to the wide range of laptop sizes and operating systems available, all accessories provide information on the models they are designed to work with.

Having a good laptop battery is one of the most important parts of owning a laptop, especially if you intend to take advantage of the laptop’s portability; without a good battery, your laptop will need to be plugged into the wall much more frequently, limiting your ability to take it with you. Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won’t charge fully or stops holding its charge for as long; when this happens, you’ll probably want to buy a replacement battery.

There are many laptop battery manufacturers, and even more retailers to buy your laptop battery from. However, your biggest concern in purchasing a laptop battery will be to choose the battery that fits your computer. For this you will need to know the make and model number of your laptop; if you don’t know this offhand or don’t have the necessary paperwork, check the inside of your laptop’s battery compartment while the computer is off and unplugged. There you should find the model number, along with some other information. You may also find the part number of your laptop battery, located on the casing of the battery itself.

When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.

The nickel cadmium battery, known as NiCad (pronounced “Nigh-Kad”), used to be the most common type of laptop battery. Nickel cadmium batteries couldn’t hold very much power by today’s standards, and could only be charged a limited number of times. NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the “memory effect,” meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it.

The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect — although it wasn’t as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn’t have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.

Regardless of which type you have, it’s important to properly care for your laptop battery, in order to get as much life out of it as possible. “Conditioning,” which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery. Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it’s a good idea to condition all laptop batteries regularly, rather than simply leaving them plugged into the wall at all times. Your laptop battery should never be stored in an area that drops below 50ºF (10ºC) or rises above 95ºF (35ºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled. Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.

Under normal circumstances, the average life of a laptop battery is roughly three years. However, some users are able to employ a few simple tricks and enjoy anywhere from five to seven years of use before having to replace the battery. If you want to know how to get the most from your laptop battery, here are a few ways to extend the life without having to make a great deal of effort.

First, the laptop battery should not allow to remain unused for extended periods of time. If you plan on not using your laptop for a couple of weeks, remove the battery from the unit and store it in a cool dry place. When reinstalling the battery, follow the manufacturer’s procedure for charging a new computer battery to bring it back up to full strength.

Even with laptops that are used daily, it is a good idea to disengage the AC power source from time to time and run strictly on battery power long enough to almost exhaust the power supply. The reason for this is that laptop batteries are subject to what is known as a memory effect. By only running the battery down to half capacity, the battery can effectively forget about the other 50% and begin to malfunction.

Using full battery capacity at least once or twice every couple of weeks will minimize this effect and keep your battery charging at optimum efficiency. Keep in mind that not all laptop batteries are subject to this phenomenon. If you use a Li-Ion or Ni-Mh laptop battery, you don’t have to be concerned about memory effect.

Avoid any actions that would lead to damage to the laptop battery. This means making sure the battery is not exposed to moisture or extremely high temperatures for long periods of time. Take care to not drop the laptop battery on a hard surface. Any of these incidents can crack the casing and possibly damage the battery cells.

Last, clean the laptop battery contacts from time to time. Minute amounts of dust and residue can collect on the contacts and create an extra strain on the battery during charging activity. Use a simple cotton swab dipped in rubbing alcohol to gently clean the contacts every few months and the battery should last a little longer before a replacement is needed.
