Does it seem like no matter what you do, your computer is always out of battery power? It might be time to replace the battery. Every battery has a designed capacity-basically the amount of charge that it's designed to hold. Over time batteries lose their ability to hold a charge. This means that even though you're fully charging your battery, the actual amount of power that the battery can hold is going down.

Some of the telltale signs that your battery is going bad are shorter use times, and subsequently, shorter times to recharge. If you notice the amount of time you can spend unplugged is going down, then chances are your battery has lost much of its ability to hold a charge. Another sign that your battery might be on the wane is that it takes less time to recharge. A battery that's going bad might also cause your computer to turn off or hibernate unexpectedly, even if the battery meter displays ample capacity remaining (70 or 80 percent).

Fortunately, Windows can help you know when your battery is unable to hold a full charge. When your battery gets down to 40 percent of its original capacity (that is, it can only hold 40 percent or less of its designed capacity after it has been charged), you'll see a notification via the battery meter icon that your battery might be going bad. This notification is new in Windows 7-earlier versions of Windows can't notify you when your battery is going bad. If you don't want to receive this notification, you can turn it off by clearing the check box on the battery meter.

Battery meter showing a notification that a battery might be going bad

Many batteries will show signs of problems well before reaching 40 percent of their original capacity. Also, many computer manufacturers have programs that you can use to measure the performance of your battery. These programs might be more sensitive to battery problems and should be used first to check the condition of your computer's battery. For more information about solutions to this problem, see Solutions to common battery problems.

Note

Some computer manufacturers report the designed capacity of their batteries to be the level of the last full charge, so it's possible that your battery might be below the warning threshold without giving you any warning. If your computer continues to run out of battery too quickly, but your battery meter shows that it's fully charging, it might be time to consider replacing your battery. Check with your computer manufacturer for information about replacing your battery.

Using the battery meter to monitor power consumption

• The battery meter is a handy tool located in the notification area of the Windows taskbar that makes it easy for you to keep an eye your computer's power consumption. The battery meter icon indicates whether your laptop is plugged in or whether it's running on battery power . When you point to the battery meter, you can see the percentage of battery charge remaining as well as an estimate of how much time you have until you'll need to plug your computer in.
• When you click the battery meter icon, you can get more information-like which power plan you're using and, if you have more than one battery, how much charge is left in your second battery. You can also change power plans and access additional settings for managing more power options. For more information, see Battery meter: frequently asked questions.

Using power plans to save your battery

One of the easiest ways to save your battery without affecting the performance of your computer is to use one of the built-in power plans that come with Windows. Power plans are basically collections of hardware and software settings that control how your computer uses power. There are two power plans that come with Windows that are useful for laptops:

Balanced. This is the plan that most laptops use by default. It offers full performance and display brightness when you need it and saves power during periods of inactivity.
Power saver. This plan can help you get the most from a single battery charge. It saves power by reducing system performance and screen brightness.

In addition to the power plans that come with Windows, your computer manufacturer might offer additional plans. You can also create your own power plan, or customize the settings for one of the existing plans. For more information, see Change, create, or delete a power plan (scheme).

Getting the most out of your battery

In addition to using power plans to get the most mileage out of a battery charge, it's also important to take care of your battery to make sure you get the most life out of it.

• Make sure you're following the manufacturer's instructions for charging and maintaining your battery. Only use a charger and power cord supplied by the manufacturer.
• Don't let your battery get too hot (or too cold). A hot battery is a sign of trouble and usually means that your battery isn't working properly. You should stop using it right away. Also, make sure that your battery isn't exposed to extreme temperatures. Batteries are designed to work best at room temperatures. Avoid using (or even storing) batteries in extreme temperature conditions.
• Use your battery to keep it fresh. Don't keep your computer plugged in all the time. It's a good idea to discharge and then recharge your laptop battery about once a month. Also, you should let your battery run down before you recharge it.

Paris wants to rent electric cars

Paris wants to rent electric cars

The French capital Paris wants to offer the autumn of next year, a total of 4,000 electric cars for rent. The monthly subscription will cost 20 to 25 euros each and mileage is billed separately. The plan provides for a reduction of the heavy traffic in Paris for at the moment are there every day millions of private cars on the road who drive on the roads. The electric cars will reduce air pollution and lead to a better quality of life.

It is a community of interest be created where 30 cities and municipalities are included. In Germany there are already pilot projects, the energy group RWE AG is in some big cities on a power station network, offering electric car packages for private clients. However, it will take until the electric vehicles have come to dominate the car market and that if both the range was increased and the purchase prices have fallen. The problem of the range should be resolved through development of more powerful batteries. The idea of an electric car rental in Paris is certainly a precedent and other cities to convince also rent electric cars.

Proton exchange membrane fuel cells

Proton exchange membrane fuel cells

Proton exchange membrane fuel cell (PEMFC) with high specific power, high energy conversion efficiency, low start, environmentally benign, it can be used as power source for a variety of vehicles, is also a fixed station, portable electronic products the ideal power supply, therefore, PEMFC has become a hot research around the world [1]. PEMFC by the membrane electrode assembly (MEA), flow field plate, conductive plate, and other accessories, including one membrane electrode assembly by a proton exchange membrane (PEM) and gas diffusion electrode (GDE) composition. PEMFC is a solid polymer electrolyte membrane (SP) also known as proton exchange membrane, now widely used perfluorinated sulfonic acid membrane (PFSAM), such as the Nafion series; PEMFC electrode is a porous gas diffusion electrode, in accordance with the reaction gas electrode in different transport mechanisms can be used in the electrode current PEMFC electrode hydrophobic and hydrophilic electrode is divided into two types. Hydrophobic electrode reaction gas is formed in the hydrophobic water-repellent agent network transmission, while the hydrophilic electrode reaction gas is first dissolved in water or Nafion, the further proliferation of delivery [2]. Usually, MEA from the proton exchange membrane and gas diffusion electrodes made hot pressing, which is the core part of PEMFC, directly determines the battery's working performance, its structural design and preparation process is the core technology of PEMFC research.

Different from the traditional electrode is hydrophobic, hydrophilic electrode catalyst layer does not contain hydrophobic agent, its preparation method is the direct catalyst and the formation of Nafion resin uniformly mixed slurry coating on the gas diffusion layer or membrane. At present, MEA is also based on preparation of most of the hydrophobic electrode, the catalyst efficiency is low [3]. Preparation of the MEA based on hydrophilic electrode is in the research phase [4 ¯ 10], but the catalyst can further improve efficiency, production cost can be further reduced, its performance can be better than the hydrophobic electrode, is expected to be widely used in PEMFC. We are prepared using hydrophilic electrode MEA, with constant current polarization and electrochemical impedance spectroscopy (EIS) electrochemical method of electrode structure and composition on the performance and to determine the optimum parameters of MEA performance.

Research to develop integrated production only 54μm thick crystal silicon solar cell, conversion efficiency of 12.1%

It is reported that Japan's Institute of Industrial Science and Technology (JST) using amorphous silicon and crystalline silicon heterojunction developed a 54μm thick solar cell modules, and has confirmed that cell conversion efficiency of 12.1%. Production & Research Institute in July 2008 ranged from 28 to 29, the future of the Science Museum in Tokyo, Japan at the "results of the fourth solar energy research center report" on the release of such solar cells. Crystalline silicon solar cells and the existence of crystalline silicon supply prices and other serious problems. The thin is the decisive factor in cutting costs, increasing R & D activity.

The use of amorphous silicon and crystalline silicon heterojunction solar cells developed in the crystalline silicon layer of one or both sides of the amorphous silicon thin film formation. This Sanyo developed "HIT (heterojunction with intrinsic thin layer)" structure is basically the same unit.

This time, producing comprehensive study using double-sided form in the crystalline silicon layer of amorphous silicon thin films can greatly reduce the thickness of crystalline silicon to achieve a thickness of only 54μm. "In the double heterostructure-based products for the world's thinnest" (JST). The cells can be easily bent by hand.

However, after the thin-cell conversion efficiency is decreased. Thickness of 300μm, the conversion efficiency of 17.5%, while the thickness of 54μm, the conversion efficiency dropped to 12.1%. This is after thinning, the infrared wavelength greater than 900μm due to reduced efficiency.

Traditional electric car battery charging hard

City suffered the pain of the people traveling car expressed an unprecedented enthusiasm. Try to ride the spot required. Recanalization sales staff to explain the operation issues with enthusiasm, was also riding in a circle, with the uniform rotation control handle, light red light flash, the car turned up on smooth, feels really great.

Metalworking excited to introduce the traditional lead-acid battery electric bicycle generally in the 14-19 kg weight, heavy battery to allow more users have suffered the strain of the upper and lower floors suffered charge. Such a small pocket electric bike is a real portable means of transport. It can be folded into the subway, so you can easily shuttle between the city and can be placed in the trunk of a taxi and bus, to facilitate travel carrying purposes. And can you happen, you can gently mention stairs or the elevator, on the corner of the balcony or living room can be, do not have to worry about stolen away.

R & D process was very complicated

Metalworking frustrating introduction to the company in research and development process, can be said to have gone through difficulties. The first generation of products off the assembly line last year, R & D personnel in the light of the pursuit vehicle, with a disc brush motor, although the car lighter, but the electrical properties of unstable and battery power is very small, it continues the course just over 10 km . Travel far to meet the short-term needs. Although the second generation of the power increase, but the motor still does not improve, leading to practical function of product affected. R & D group of company leaders and decision of the final study: self-developed machine one brushless wheel motor. And again increasing the battery power. Brake system of the body and re-set, light open mold on the cost of millions. One-year-old, has finally successfully developed. Now in volume production market.

The world's leading technology products

Traditional environmental pollution battery electric cars much, but the key solution is to upgrade the battery core technology. In China, Beijing, Shanghai, Guangzhou, Shenzhen, Haikou, Changzhou all electric vehicles were introduced road against local regulations, medium and small cities across the country will be divided into different time periods the road against traditional electric cars. Lead-acid battery electric vehicles out of the market is a foregone conclusion. Lithium was recognized green product, it does not contain any heavy metals, the production process does not use water, the production of exhaust all subject to recycling, raw materials and lithium carbon-based. Not produce solid pollution. So, pay attention to environmental protection in Western countries to encourage green energy, electric bicycles are powered by lithium. Seen in this light, traditional electric cars will be replaced by lithium micro-electric vehicles.

Reperfusion produced lithium micro-battery-driven electric vehicles using lithium, the battery does not contain such as cadmium, lead, mercury and harmful metals in the manufacture and use and give up no environmental pollution. Under the frame containing the lithium battery, battery back into the big bar, you can directly plug the charger, front wheel hub brake with brake, rear brake only to establish security and stability. With the folding pedal device for a long time people in recreational sport and static electricity is insufficient long-range riding purposes. Products through national technical supervision, strict testing quality and safety testing, quality inspection report to obtain authority. Marked reperfusion lithium micro-electric vehicles based on traditional electric cars, find the quality of the cross point, the support points led the company in Nanjing and then rose through the ranks to the high-tech enterprises, the technology has been far ahead in the international.

Gold Industry Market blank

Green electric vehicles is considered to occupy the 21st century dominance of public transport vehicles is an indisputable fact. As a revolutionary high-performance environmentally friendly electric vehicles on behalf of progress - and then through the emergence of lithium micro car, the light effort, environmental protection, energy conservation, the characteristics of affordable, very popular among consumers, will be the city's new transportation highlights. Lithium-power micro-electric vehicles as a new industry is naturally enticing, full of hope and sunrise. In the domestic market, lithium micro-car market is in a period, in broad consumer market with unlimited number of cities, is still hard to find any sign of it. Market opportunities will be unlimited blank.

Recanalization lithium micro-car from the product launch date, several hundred times the daily volume of telephone counseling, more discerning business can not wait, have come glimpse of lithium micro-electric vehicles for hosting the Games, and on-site contract. At the same time the company introduced a number of further support through measures to ensure the correct order and sales agents throughout the rapid expansion of the market.

Following a motorcycle, after the glory of traditional electric car industry a golden opportunity, lithium micro-electric car will travel to the future of a revolutionary storm off the field.

Verdi calls for state aid for Arcandor

Verdi calls for state aid for Arcandor

The services union Verdi calls for state aid for the ailing retail and tourism group Arcandor. latitude e6400 battery The company wants to separate the meantime by his Karstadt stores. It should already be a potential.

"All the ways to stabilize Arcandor should be used," said the vice-chairman Verdi Margret Moenig-Raane the General in Essen West German newspaper published today. "These include guarantees or loans easier."

Concerns about a potential burden on taxpayers rejected it. "The fact that a state guarantee, tax money would be used, nothing special for Arcandor," said Moenig-Raane. Concessions from the employees they refused. "Another savings contribution of employees is no longer there," she said. The Verdi deputy chief who is a member of the Supervisory Board, Arcandor has pointed to the ongoing redevelopment agreement, waived by the employee within three years to 350 million euros. dell latitude e6500 battery

Meanwhile it was announced that the retail group Metro has interest in the Karstadt department stores. However, Metro is only interested in a takeover, even if the premium department stores are included KaDeWe in Berlin, Hamburg and Alsterhaus Oberpollinger in Munich in the package, the Bild newspaper reported on Tuesday. Metro spokesman Ruediger Stahlschmidt said the group give "no opinion on market rumors from."

Karstadt and Kaufhof, Metro-daughter are the last remaining large department store chains in Germany. However, the department stores in the past decades have steadily lost market share to rivals such as the textile chain stores like H & M and Saturn. It has long been speculation about why a merger of the two remaining companies. The economist, Joachim Zentes of Saarbrücken University holds a combination of the company for almost inevitable. "Everything indicates that, on the German market in the long run is only" for a department store chain space, "he says. latitude d505 battery

However, there are big hurdles for a merger. Actually is the department store chain Kaufhof at Metro rather the way out. The retail giant had the store's daughter has already put on the sales list because he wants to focus on international expansion opportunities in the wholesale chain Metro Cash & Carry, in the electronics market chains Media Markt and Saturn as well as the hypermarket chain Real.

In Union and the FDP, meanwhile, concerns were taking too loudly against the reflections of the parent group Arcandor's Karstadt, in the fight for survival also helps the public to complete. The Chairman of the Parliament circle middle class in the Bundestag, Michael Fuchs (CDU), said the Morning Post Online that he saw "no justification for it to step in in this case, with government help - especially in the case Arcandor obviously not the financial crisis is the cause" for the problems. Even the FDP economist Rainer Brüderle warned from the KaDeWe department store could not be state-owned enterprise. "It can not be, that comes in medium-sized and large groups of vultures of the eagle." lenovo thinkpad x60s battery

Arcandor CEO Karl-Gerhard Eick wants to save the ailing company with a Schrumpfkur: For sale are the luxury-goods houses of the Group. Eight normal department stores, shops and 115 in 1500 Source Technology Center of the mail order for use. Affected by the planned restructuring, approximately 12,500 of the 86,000 company employees.
