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.

EV battery market will decide to change the fate of the car battery

According to reports, as the electric vehicle (EV) universal touchstone of the new Nissan EV "green" to attract a lot of attention. Many automotive and battery-related heart and soul who are concerned about their booking. In Europe and China, the government and local governments have introduced preferential policies EV, EV previously skeptical of the car manufacturers are contracting cooperation, and gradually began operations. Reporters attended the International Conference on the car battery "AABC 2010", probing its movement.

Nissan President & CEO Carlos Ghosn: "Nissan - Renault Group by 2012, annual sales of electric vehicles (EV) 50 万辆." - Nissan has everything is ready, will be held in December 2010 listing of the EV "green." Stakeholders are many automobile stare at the car booking conditions. This is a matter of course. Because the sale of green leaves, is directly related to the company's currently hybrid (HEV) based commodity strategy to change direction.

In this case, Nissan June 7, 2010 announced that its booking two months in Japan over 6000, reaching the 2010 target annual sales in Japan. Reported in the United States has more than 13,000 reservations.

Nissan will follow the original plan, establishing an annual output of 50 000 in Japan, the production system. And, as in the United States from 2012 to produce an annual output of 150,000 leaves the system, including battery manufacturing, including plant construction, has been started from May 2010. The company has shown that common with France's Renault in Europe began in Portugal, France and the UK production EV with a lithium-ion rechargeable battery, and its policy towards the production of an annual output of 500,000 systems.

Nissan has been able to plan for the EV implementation of the background is so strong, Nissan - Renault Group and local governments in close cooperation, grants, etc. to promote the benefits of EV system is established, and local government participating infrastructure construction progress. Moreover, not only in Europe, Japan and the United States and other developed countries in the world's largest auto market - China, EV incentives are also expanding.

Daimler and Toyota will also be converted policy?

With the preferential policies to enrich EV, EV car manufacturer between the capital and technology to become more active cooperation (Figure 1). Surprisingly, even the doctrine had been carrying out an independent Toyota, also announced the company will be the risk of advanced EV Tesla Motors invested U.S. $ 50,000,000 Note 1). Toyota has so far to take advantage of HEV and household power for the car battery, can travel a certain distance from the EV plug-in hybrid (PHEV) to the mainstream, recently began to gradually shift working EV.

Figure 1: Electric vehicles around the complex relationship

Focus on electric vehicles such as EV and HEV development co-operation between car manufacturers increasingly complex. Some car manufacturers even with a number of lithium-ion rechargeable battery manufacturers to develop.

Note 1) Toyota 21 May 2010 contribution to the Tesla Motors and their components on the EV development, production systems, and technology-related business cooperation agreement. Estimated that Toyota and GM vehicle production company established a joint venture NUMMI off, but Tesla also purchased the site have a greater impact on the partnership.

In addition, the European car manufacturers due to the introduction of EU incentives for EV, EV market have announced the beginning Note 2). Germany's Daimler (Daimler) is particularly active. The company announced in April 2010, decisions and Nissan - Renault Group each hold 3.1% of the shares of the companies in small cars, including EV, including joint development of cooperation in such areas. "In the future there may need very substantial costs of electric vehicle battery joint venture" (Nissan's Ghosn).

Note 2) France plans to spread 100 000 2015 EV, is also planned in the 2020 production of 2 million EV. Germany plans to spread one million by 2020 EV and PHEV, 2020, the Irish plan to spread 225 000 EV. In addition, research and development of European industry forum - the European Technology Platform (European Technology Platform) goal is to spread one million total in 2016 EV and PHEV, 2020 popularity 5 million cumulative EV and PHEV.

Daimler EV cooperation around more than that. The company also envisages the expansion of EV market in China, and in June 2010 jointly established with BYD EV Daimler developed the new joint venture company in Shenzhen BYD Co., Ltd. (Shenzhen BYD Daimler New Technology).

In addition, European manufacturers of the French Peugeot-Citroen (PSA Group) will be accepted from mid-2010, Mitsubishi Motors "i-MiEV" supply, began selling in Europe. Germany's Volkswagen in 2013 listed three EV. The company plans to make EV prior to 2018 accounted for 3% of the company's sales.

EV battery market will change

These have begun to move around the EV electric vehicles to the main components - a tremendous impact on vehicle battery market. This is due to the previous electric vehicle HEV will be recognized as the mainstream. HEV is equipped with a battery capacity of only 500 ~ 1kWh so, if you want to get the battery manufacturer effects of mass production, required to supply a number of car manufacturers. But if you can increase the popularity of EV is another matter. Because EV is equipped with a battery capacity of about 20 to 40 times HEV.

For example, Nomura Research Institute predicted in 2020 the market for electric vehicles (excluding mild HEV) is about 8.5 million. Still over 600 million of sales in the mainstream HEV, EV less than 1 million (Figure 2). But be regarded as the car market, then the battery, EV battery according to the amount calculated with the car will account for half. Because EV uses a lot of car batteries.

Figure 2: Due to the expansion of EV lithium-ion rechargeable battery market

Nomura Research Institute forecasts, EV electric vehicles in 2020, but the proportion of the market accounted for more than one percent (a). However, the amount calculated by a car battery market mostly occupied by the EV battery (b). In addition, HEV does not include mild HEV. Figure based on the data made Nomura Research Institute.

Taiwan's silicon cells in 2010 challenging the world's second largest shipping

According to Industrial Information Institute for Information Industry (MIC) estimates that by 2010 global solar market will exceed 12,000 megawatts (MW), and the size of the market in 2009 compared to the more, the growth rate of more than 60%. The first half of 2010 shipments of solar cells in Taiwan about 816.6MW, the annual growth rate of 160.1 percent. Estimated Taiwan solar silicon module production capacity is expected to reach 1,778 MW, the annual growth rate of 101.6%.

Global solar market in 2010 will show a rising trend overall, due to the first half of the rate cut by the German government's policy statement impact, sparking an get the building trend, while in the second half is expected in Italy, France, the Czech Republic and the United States and other countries have invested in the market, along with Japan, China needs to enhance the 2010 global solar market is expected to grow substantially.

Industrial Information Institute for Information Industry (MIC) of high Hongxiang industry consultant, said that Taiwan solar manufacturers in early 2010 conducted a large-scale expansion, addition to the first silicon material manufacturers have started trial production, the wafers, cells, modules show substantial expansion of production capacity situation. Among them, the first and second quarter shipments of silicon cells, respectively over the same period last year growth of 307%, 160%, with shipments in 2010 are expected to challenge the world's third largest, or second chance. Taiwan's production capacity in most cases the layout to the existing petrochemical, semiconductor industry based on technological capabilities, close to the supply price, quantity and stability of the upstream material for the silicon material, silicon vendors to create the basic conditions for survival, with cell manufacturers substantial expansion of plants, the growth of upstream industries can be described as beyond doubt.

To MIC, said the financial turmoil has resulted in a substantial decline in product price, cost competitive pressures, the European module, solar cell manufacturers due to high costs, making outsourcing, increased pressure eastward, while the Taiwan solar cell manufacturers to quality, prices are relatively competitive advantage, and further prepare for a substantial expansion of production capacity. Observe first quarter of 2009 1,952 MW capacity and the fourth quarter of 2,487 MW capacity growth trend, and in 2010 the first and second quarters, respectively, compared with same period in 2009 grew 34.9%, 50.5%, production capacity has expanded rapidly increased to 2,634 MW and 3,104 MW expected second half 2010 to first quarter of 2011, on a quarterly basis will be maintained for more than 70% capacity growth.

Looking forward to 2010, in large ICT companies with strong financial, global logistics system, brand, cut into the solar module manufacturing capacity and system, Taiwan's PV industry, previously regarded as the weakest link at this time significant increase can be described as competitive, it is expected there will be considerable opportunities for the future with a showdown in mainland China manufacturers. The cost and quality advantage, Taiwan in 2010 is expected to silicon, solar cell manufacturers to obtain the order should be no doubt. Therefore, the ability to successfully obtain the equipment and funds the season, winning companies will be decided whether or not the key factor.

As the cells continue to enhance the competitiveness of firms, competitive advantage can spread this first, downstream, and the formation of a virtuous circle, shaping the overall competitiveness, industrial policy is yet to be blessing. In addition to emerging technologies, manufacturing equipment, system components such as R & D capabilities to enhance, the ability to help the system vendors to develop the domestic market, as well as the dedication is still to pay, such as certification, financing, evaluation system, are actively involved in urgent need of administrative units .

Tianjin 100 car charging pile near the site to determine the full capacity

Learned from the power company, located in the town of Wah Ming city's first large-scale electric vehicle charging station has completed the main, from today into the post-renovation period, expected to be put into use next month. Meanwhile, the 100 car charging pile construction site has also been identified, will soon start the construction. The electric vehicle charging station and charge after the completion of pile construction, which can meet the needs of hundreds of cars charging for the city to provide electricity to support the development of green vehicles.

Wah Ming Town, a large electric vehicle charging station equipped with two large parking spaces, three medium and four small parking spaces. Has now completed the main task of building, being renovated, and some convenience facilities, and put into use next month after nine meet the demand of charging electric vehicles. In addition, the river at Puji electric car charging stations has also recently launched the construction, use is expected to be completed next month.

It is understood that the new charge to cover all the basic facilities charge standards, both can use the plug-in charging mode, it can directly replace the battery. Power company officials, for example, a pure electric car consumption per hundred kilometers is only about 7-12 kwh, to a certain type of pure electric vehicles, for example, if the ordinary charging mode, 2 hour charge can travel 300 km, if use of fast-charge mode, a half-hour can be filled. Such as battery replacement means that customers hire a battery pack. When the vehicle battery is running out, the customer drove the car to the charging station, the other a battery replacement, easy to taxis and other users in the same time, can also take advantage of power battery storage for peak load regulation characteristics. It is reported that State Grid Corporation of the city is first pilot applications of electric vehicles is one of seven provinces, there are 22 pilot run of pure electric vehicles, city-wide coverage with five charging stations and the construction of 100 charging pile and application, these facilities will charge the city to provide electricity to support the development of green vehicles.

2011 global market supply is expected to lead a small shortage

LONDON, July 20 news, a survey released Tuesday shows that in 2011 the world market supply is expected to lead a small shortage, due to vehicle production growth increased demand for the batteries.

Analysts median forecast for next year expected to lead market supply shortage of some 6,000 tons less than in January estimated shortage of 52,000 tons.

Median forecast, the global market in 2010 lead to excess supply of 60,000 tons, a record high; which in January forecast of 62,500 tons of excess close.

Credit Agricole's analyst Robin Bhar said: "The demand side is critical, we is not expected to double dip and our view is that the auto industry will be strong."

Batteries used in cars, accounting for about 80% of lead demand.

Changes in supply and demand forecast in January compared with a modest, demand for lead in a downturn is more defensive than other metals.

Lead battery needs replacing about 40% of total demand.

These requirements affected by seasonal factors - the weather changes, such as the cold winter or unusually hot summer, when the old battery is usually difficult to use.

Demand growth is widely expected to stabilize, many analysts also expect tight supply will continue to limit the lead ore refined lead production, thereby preventing a substantial increase in stocks next year.

In a recent Barclays Capital report said: "We expect 2011 will balance supply and demand, due to slow demand growth, but Chinese demand is still strong, and the rest of the world demand continues to improve."

"Supply growth expected to accelerate slightly, as China continues to increase smelting capacity, but the tight concentrate market will be the limiting factor."

Barclays Capital expects global refined lead production will increase 4.8 percent next year, the global refined lead production will increase by 5.6%.

A separate survey of metal prices, in anticipation of market supply in 2011 will be a shortage next year, the average price of lead is expected to rise to 2,178 dollars per tonne, USD 1,996 per tonne this year.

LME lead cash price of about $ 1,750 a tonne on Tuesday.

Morgan Stanley in 2010 estimated the amount of lead excess supply maximum of 260,000 tons, while Barclays Capital estimates lowest excess 6,000 tons.

Lead analyst on the 2011 estimate of the expected market situation between supply surplus of 170,000 tons from 110,000 tons to short range.

Merrill Lynch is also expected to primary smelters in the Lead Mine supply will remain tight.

If from the miners received the concentrate processing fees remained at low levels, may reduce China's smelters.

Meanwhile, the two lead smelters of scrap supply is also very tight, again to help curb a lot of excess supply of lead.

Analyst Michael Widmer said: "Given the steady demand and supply growth lead-lag, we believe that the situation is full of lead supply is unlikely to continue."

"However, we continue to forecast a small surplus in 2010 and next year will supply the market will balance supply and demand in general."

Zibo battery exports increased significantly

In the first half, Zibo CIQ total exports of the battery 56 batches tested, the value of $ 2,190,000, up respectively 64.7% and 221.6%. Zibo battery exports showed a substantial growth.

Zibo is an important product of China's lead-acid battery research and production base, but its direct export less. Implementation of lead-acid batteries are the product license management, Zibo CIQ actively help the companies are familiar with export regulations and export policies and regulations, as soon as possible to remind the business license for export quality. At present, the success of the two companies to obtain export quality license.

New technologies create new opportunities for energy investments

Zhang Shuai: I like the new energy for two main reasons, one we have mentioned the new energy space, new energy to the future from the current space is expected to reach space, this space is far better than the traditional industry, this is no doubt, We believe that two investment opportunities due to technical variability, the field of new energy technologies are new, new technology, process technology in a mature technology, there will be some new sound, new enterprises have, these are for the capital market very good standard, this is my reason.

Small changes in the market space nuclear power technology less

Zhang Shuai: My logic is: the first is the market space, and the second is the changing nature of technology, market space in terms of words, nuclear power installed capacity to plan from the current installed capacity of 2020, only ten times the space, and the second, and nuclear power technology various aspects are more determined that it is hard to find a new target for investment, and the old target for investment is difficult to obtain excess returns, changes in technology can bring new investment opportunities, I am from change, from finding does not change things.

Zhang Shuai: I would like to add. From industry, the first nuclear power reserves are now affected by the impact of uranium reserves, the international community to do the planning in accordance with China's current total amount of uranium fuel to get to do, this is a problem. Second, with the increase in the amount of nuclear power plants, nuclear waste disposal is a very big problem, and the third, relatively new Chinese nuclear power plants, over 20 years, 30 years later, these nuclear power plants if they go into the maintenance period, maintenance costs will be extremely alarming, so These costs are now not come in, and gradually added to the cost of the future go to.

Technological breakthroughs to bring investment opportunities for solar energy

Zhang Shuai: optimistic about solar energy is the same logic, the first is space, space for at least 30 times more than the second is technology, because the solar technology is not mature, each of the major technological breakthrough represents a tremendous investment opportunity, because This industry is very large depth, if there is a technological breakthrough, I think it will bring a huge industry.

Promising thin-film cells and concentrator cells and optimistic about the control technology of wind power

Zhang Shuai: solar industry, which sub-sub-sectors, promising new technologies, new technology is the thin-film batteries and the main condenser batteries, thin film batteries are mainly emerging thin-film technology development company, which is the film condenser is to look at emerging business enterprises in which chain can do in advance. Optimistic about the second increase in demand, due to the large-scale industry, the opportunities brought about supporting the other incidentally I say a wind energy, wind energy, although at the back, but there is a wind which is very good, that the wind electric control part.
