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.

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.

Nuggets storage industry, capital market segmentation tends to clear

Thanks to the development of new energy industries, energy storage industry is becoming the new choice of capital Nuggets. Recently, Foshan Electrical and Lighting Co., Ltd. to 160 million yuan to buy the Hefei High-tech Energy Power Co., Ltd., China Xuan 20% stake, entered the lithium battery industry. Previously, Jiangxi Special Electric Motor Co., Ltd. and Jiangxi lithium new energy industry limited liability company, Anyuan Bus Manufacturing Co., Ltd., Beijing Shenzhou New Energy Technology giant electric Development Co., Ltd. signed a cooperation agreement, will be the development of downstream industries lithium.

Insiders pointed out that in the case of active and passive, lithium battery manufacturer may be part of the exit of wind power, photovoltaic energy storage market. At the same time, "not to do small" flow battery technology research and development on the news of success, perhaps in large-capacity storage to get more opportunities. Signal indicates that a variety of different electrochemical techniques in the market, the choice tends to clear.

Li-ion battery electric vehicle industry lock

Capital inflows in the storage industry, a series of events, the most noteworthy is integrated into the fly Technology Co., Ltd. Sichuan. The company recently said, raising 1.02 billion yuan will be holding the Air lithium battery (Luoyang) Co., Ltd., together with other sources of funds, new investment will be $ 1.7 billion for developing lithium-ion battery market.

Related to this is that an industry source said the national grid investments lose a national scenery storage demonstration project, the total 18 MW of lithium iron phosphate energy storage system to suspend the bidding, "when too large lithium batteries in the energy control is very complex, wind power, photovoltaic storage lost significance of the project had to do to consider making the national grid. "

"From the use of lithium batteries, the electric car industry will be much higher than wind power, photovoltaic industry, and this trend will remain for a long period of time." Investment adviser in the new energy industry researcher Li Sheng-mao that lithium production enterprises in the less profit margin obtained in the case, the future may be completely focused on electric vehicle battery market.

According to industry estimates, a pure electric vehicle requires 40-50 kg of cathode materials and electrolyte, a single mobile phone battery consumption is about 10,000 times, only to produce 100 million electric cars lithium-ion batteries needed relevant materials on lithium battery materials will be the world's total demand of the times. Therefore, the promotion will drive electric cars lithium-ion battery materials show explosive growth in demand.

As the market is huge, lithium batteries are relatively low barriers to entry, and is in the intensive phase of technology updates. For the current dominant position of enterprises, production and management of the future need to add a lot of money to meet the capacity expansion and the need to maintain a leading domestic technology.

"Considering the technical strength into volume production of advanced products will take time, the short term, increase integration into the flight the aircraft is not on the domestic lithium battery industry to bring greater impact." Li Sheng-mao said, but integration into the flight move to increase their investment to other investors play a certain role model, lithium battery industry will help attract more investment.

This is expected for the lithium battery industry has a core technology for SMEs, which means bigger and stronger opportunities.

"The future belongs to the public electric vehicle products, close to the broad consumer market, while the frequency of battery replacement will be higher." Electronics Co., Ltd. Huizhou billion battery market to business manager, said Chen Min, the focus of most lithium batteries manufacturers or in the electric vehicle market.

Flow into the large energy storage battery

Lithium to attend to wind power, photovoltaic industry, the size of energy storage market, there is a big reason is that lithium as rare, extensive use of facing costly problems. "Scale energy storage requirements of energy storage should cost less than the cost of wasted electricity resources." China Power New Energy and Energy Storage Committee Secretary-General who said the summer.

In contrast, longer life, lower cost of vanadium battery obvious advantages. "Vanadium battery technology matured, kilowatt-class products have been in the industry of the production stage." CAS Dalian Institute of Chemical Physics Professor Zhang Huamin introduction. Independently developed by his team of 2 kW vanadium battery durability demonstration evaluation system since July 6, 2007 demonstration run since the beginning, the cumulative run about 1,100 days to achieve a full charge and discharge cycle nearly 7700 times.

"Hokkaido, Japan vanadium battery charge and discharge demonstration system has 270 000 times." Zhang Huamin that theory, the vanadium battery is no life limit.

That vanadium battery, I must mention the Beijing Prudent Energy Technology Co., Ltd.. January 2009, established less than three years to spend $ 2.15 million general low-cost acquisition of the world's leading enterprises vanadium battery VRB Power Corporation of Canada, a storage Star power company.

Almost overnight, S & P to have a patented technology, research and development team, global engineering experience and customers, and only one step away from the commercialization of reliable products away.

"We have a kilowatt-class products have entered mass production, there is a megawatt-class product is in the commercial demonstration stage." Pu can chairman Yu Zhenhua said.

Both sides of the "take-all" opportunities

Although most of the lithium battery manufacturers choose electric car battery market, BYD, and New Energy Co., Ltd. Zhuhai JETCO and a few other lithium battery manufacturers in the "not bad money" under the support, put "take" two a market trend.

It is understood that BYD currently has two product storage power station, one is a cabinet storage power station, by about 1200 the "iron battery" combination, can store 800 kwh of electricity, 4 hours can be filled , for a family of four uses about 8 months; the other is the larger size of the stationary energy storage power station, currently only BYD Electric Power Research Institute in a sample within a trial, not yet open to the public.

In contrast, this year it was built on the banks pass on the scale of energy storage becomes more active. June 12, JETCO with Huaneng New Energy Industrial Co. Ltd., Guangdong Mingyang Wind Power Industry Group Co., Ltd. signed a contract to implement and co-operation of a total 250 MW integrated power generation system scenery storage projects.

"This project, the energy storage battery systems are our R & D with the basic unit of 2000 Ah lithium titanate battery energy storage." Silver through the days of Noah, vice president, said, despite a large capacity, but the volume of lithium titanate small, can go to the lowest operating temperature of minus 40 ℃, able to adapt to the cold northern winter.

Days of Noah also said, for Southern Power Grid electricity day and night difference of $ 0.68-0.8 per unit, through silver in the Southern Power Grid has a 1 megawatt of storage power plant demonstration project co-operation.

From the global automotive industry, battery industry, power storage and lithium mining industry, senior engineers, experts, scholars and corporate leaders will gather together on the battery technology to study and exchange.

New energy vehicles and car batteries

In recent years, energy saving slogans all over the world, businesses are engaged in energy saving have been the cause. Now, the Chinese government's support for energy conservation efforts are increasing year by year, including the development of new energy vehicles for providing a great impetus. Recently, the Ministry of Finance, Ministry of Science, the Ministry of Industry and Reform Commission jointly issued "on the purchase of new energy vehicles to carry out subsidies for private pilot's notice", these initiatives not only promote the development of new energy vehicles, also led with closely related to the rapid development of automotive battery market.

Currently, the new energy vehicles mainly plug-in vehicles and pure electric vehicles, etc., and its development depends largely on battery technology. And the lithium battery as the main representative of the cost, performance, life and charging, and security, there are still many problems, making the development of new energy vehicles has remained at the bottleneck port, difficult to spread.

How will the automotive industry and the battery industry closer together?

Car battery in the battery industry's top technology development, and because energy is directly related to the new popularity of cars, so its development for the future development of the automotive industry is of great significance. The development of battery can these two sectors more closely linked together. In fact, the domestic battery of a certain size there are thousands of companies, engaged in the production of automotive batteries hundreds of related, but really have the ability to get involved in the production of automotive battery business only a few ten. Car batteries annually, and there are many exhibitions and seminars, but unfortunately only with the respective industry focus, unable to meet the mutual understanding and communication of urgent needs.

This year, "SAE International automotive battery Summit" will be held September 1-3 at the Shanghai Marriott Hotel Hongqiao Hotel. In particular the Forum invited the United States Advanced Automotive Battery Company (Advanced Automotive Batteries) president and a full battery consulting company (Total Battery Consulting, Inc.)

New investment in energy planning into the draft by 5 trillion

July 20, the economic situation in the first half of the national energy conference, the National Energy Board Planning Division, said Jiang Bing, the emerging energy industry planning has become a mature manuscript, is preparing to report the State Council. The plan proposes that, from 2011 to 2020, will increase total investment of 500 billion yuan, 1.5 trillion annual output value will increase.

Annual output value of 1.5 trillion by

And media reports of "new energy plan" is different from the National Energy Board will eventually plans name as "emerging energy industry planning." Jiang Bing explained that the plan includes not only wind energy, hydropower and nuclear power, including the upgrade of traditional energy sources.

River ice, and now has become more perfect and mature planning, preparations are being submitted to the State Council in accordance with the procedures for approval. According to preliminary estimates, implementation plan, 2020 will greatly reduce the excessive dependence on coal demand, the year of sulfur dioxide emissions can be reduced by about 7.8 million tons of carbon dioxide emissions by the year about 12 million tons. Planning period to increase accumulated direct investment of 500 billion yuan, an annual increase of output value of 1.5 trillion yuan.

In addition, the "five" is China's implementation of the "non-fossil energy sources by 2020, accounting for the proportion of primary energy consumption reached about 15%" and "2020 carbon dioxide emissions intensity per unit of GDP than in 2005, down from 40% to 45%" Two target the critical period, the National Energy Board is organized to carry out "five" energy plan for the work.

Fear of the fourth quarter are "gas shortage"

In the conference, the National Energy Board Secretary Zhou Xian expects the second half of the international energy situation is expected to remain cautiously optimistic, energy supply and demand situation is stabilized. Meanwhile, with the natural gas pipeline in Central Asia increased, domestic production growth and increased imports of LNG, natural gas supply capacity will increase, but supply and demand still exists. Gas during the height of the fourth quarter, some areas may still be gas tight.

In the first half, the state has increased the price of natural gas prices and pipeline, natural gas as raw material for chemical production costs rose sharply. National Energy Board that the second half of the chemical gas consumption may be reduced.

It is reported that "Last year, China has surpassed the United States as the world's largest energy consumer." Zhou Xian, said the International Energy Agency on the status of China's energy utilization of new energy development, especially do not understand, according to the National Energy Board's calculations, although in 2009 China is the world's largest primary energy producer, but the U.S. remains the world's largest energy consumer

Nuclear energy, wind and solar to see profit margins to see technical details

New energy term, both for the 2010 capital market or the international community, are the highest attention to a word. In the increasingly competitive energy now, people are more efforts to explore a new alternative energy sources. With the new concept of energy-related stocks, listed on the first day since the beginning, they were in hot pursuit of investors. So the prospect of a new energy future in the end?

July 16, the industry's elite gathered CCTV "transaction time" special program "Financial swordfight" swordfight new energy theme.

Guoxin Securities analyst Chung Dong-young, chief of new energy industry that the new energy in the second half there will be periodic adjustments. The main reason is optimistic about the new energy future based on the industry's development trend. But because the new energy policy under the guidance of the investors' preferences, the market has gone up another wave, so the next to have a high valuation adjustment process.

Wind power equipment space in the international market optimism. Chung Dong-young that from China's manufacturing industry in terms of wind power equipment manufacturing market from domestic to international, which is a lot of space. China's wind power equipment manufacturers not only meet the domestic market, but more can provide relatively abundant wind energy resources to foreign countries.

From the sub-sectors, Chung Dong-young promising smart grid and wind power control technology. Because the key is in the technical breakthroughs, there are smart grid control technology, which has room for two.

Great Wall Securities analyst Zhou Tao of new energy industries that will be the second half of the new energy market investment. First, this year, circulation of money market shares do not move, then the investment will focus on new concepts such as energy; Second, the industry vision for the better, so the letter is the second half of the new energy market investment. Not saying up some opportunities or out; sometimes the stock is nice, fell and rose.

Because a clear prospect of nuclear power, the new clothes the next few years, what is new, what is put into operation, equipment to determine when and how income, all determined, companies are now relatively reasonable valuation, future investors will get nothing. So Zhou Tao believes that nuclear power gains can be expected.

Select the position of the key advocates Zhou Tao, long life cycle of the industry. Because the cakes are placed in it, first select the status of cake are strong, that is very critical of the industry; second choice has been able to eat, the longer the life cycle of the industry, so the market will always balance, often have to wait for opportunity ago.

CITIC Securities chief analyst Liu Lei, the new energy industry that, to judge from the life cycle of the prospects of new energy sub-sectors. China's wind power is actually in China's high growth period has passed, then nuclear power is very clear in the next decade will be China's high growth period, it is just an early stage, such as solar energy we feel at the outbreak of the growth front.

Liu Lei believes that nuclear power is about to enter period of rapid growth. From several sub-sectors in which the life cycle to determine which industries are the best investment. This perspective, nuclear power in China has been very clear in the next stage is the fast-growing, and now, then, is the early stage of explosive growth.

Specifically, Liu Lei optimistic about the nuclear power equipment. Because large-scale nuclear power is now in the early stages of development, those who participate in the nuclear power equipment and equipment inside the host Ye Hao, supplies Ye Hao, in fact, can be optimistic at the beginning. But from a long time, if it is consumable life cycle will be longer. The second is now China's nuclear power equipment localization rate is very high, second-generation semi-skilled high localization rate of 70% to 80%, three generations of technology, the localization rate is very low. Thus, more optimistic about the import of some of these alternative technologies equipment.

State Securities analyst Zhang Shuai, chief of new energy industry that new technologies create new energy investment opportunities. Promising new energy for two main reasons, a new energy to the future from the current space is expected to reach space, far better than the traditional industry, this is no doubt. The second is the variability of technology, new energy technologies are new, there will be some in the process of maturation of new technologies improve, new companies appear, these are very good for the subject of capital markets.

He believes that technological breakthrough for solar energy to bring investment opportunities. Optimistic about solar energy is the same logic, the first is space, at least 30 times the space above; second is technology, because the solar technology is not mature. Every major technological breakthrough means that a huge investment opportunity, because this industry is very large depth, if there is a technical breakthrough will bring a huge industry.

Solar industry sub-sub-sectors which, Zhang Shuai promising new technology, new technology and concentrating mainly thin-film battery cells, thin film batteries are mainly emerging thin-film technology development companies, emerging companies in the condenser is to look at which companies can pre-industrial chain well. At the same time, he likes the increased demand, due to the large-scale industry, the opportunity to bring supporting.

"Securities Daily" Deputy chief editor Dong Shaopeng also believes that nuclear energy prospects are very clear. He mainly come from industry trends to determine, because the nuclear fuel, technology and national planning and global trends are identified, particularly in terms of China, needs to develop nuclear energy. The prospect of nuclear energy is very clear, but wind and solar power, the key is in power, the storage and transmission still faced some technical bottlenecks, there are uncertainties, they are two at the back.
