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.

Battery meter showing power plans
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.

Shopkeeper magnetism: 873 million yuan to pound heavily in solar market

By the positive news, July 26, shopkeeper magnetic (17.47,0.57,3.37%) (002,056) 18.59 yuan upward in order to limit the opening. The latest announcement, plans to invest 873 million yuan in Hengdian East magnetic crystalline solar park investment and construction of 300MW and 50MW silicon solar cell component project. Shopkeeper magnetism secretaries WU Xue-ping the "Securities Daily" correspondent said: "Although the market is expected to shrink the market next year, short-term overcapacity, fierce competition in the market saying, but we are optimistic about the prospects for the solar industry, the company began investing last year 100MW crystalline silicon solar cell production line, are now relatively smooth, good earnings. "

Main magnetic materials recovery

Large contribution to first-half profit

According to the shopkeeper magnetism July 6 announcement, the company expects in 2010 a quarterly net profit from January to June 2010, an increase of 100-140%. The estimated results are corrected for the 2010 first half net profit rose 130% -160%. Said, the overall warming of the economic situation this year, plus the company's management strengths, reduce costs, develop new markets, greatly enhance the revenue and net profit.

Deputy General Manager WU Xue-ping said: "The first half of the profits or the main contribution to large, but crystalline silicon solar cell production line quick, investment and output have three to four months, ended June 30, solar cell production line sales revenue of 8800 yuan, total profit of over 100 million. "

Great Wall Securities Yuexiong Wei introduced shopkeeper for domestic ferrite magnetic ferrite materials and leading manufacturers, market share of the first, which the world's first permanent production (in 2008 about 7.4 million tons), Soft production first (in 2008 about 2.6 million tons). 2008's ferrite permanent magnet and soft rice cake products in the country's market share was 16% and 10%. For the shopkeeper main magnetic ferrite magnetics products, Everbright Securities (16.27, -0.05, -0.31%), Zhao Lei that, globally, Ferrite Magnets higher degree of homogeneity of products, product prices with demand volatility, so the industry is a high flexibility. For style sound shopkeeper magnetism, the business should be to broaden the board of the chess.

Indeed, as Deputy General Manager WU Xue-ping said shopkeeper magnetism, the solar industry should be optimistic. The Chinese government in the "long-term renewable energy plan" put forward, solar photovoltaic power generation capacity by 2010 will be developed to 450MWp, while the installed capacity of solar power by 2005 only 6.5MWp, which means that the compound growth of China's solar energy capacity rate will be up to 38%, and "low-carbon economy" is that fossil fuels such as coal, oil, etc. to use as much as possible the use of biomass energy, wind energy, solar energy. New solar energy as a renewable energy, is considered to be the 21st century, one of the most important new energy, the development of a larger space.

Solar-oriented

See European "face."

Deputy General Manager WU Xue-ping, admits: "Our risk from those who we are later involved in, and now the scale is 100MW, 300MW to vote in, to 400MW." According to the announcement, 873 million yuan project will be fully operational 300MW per year production of crystalline silicon solar cells film and 50MW of solar modules production capacity, annual sales income of 3.1 billion, total profit 304 million. Shopkeeper magnetism gradually improved solar PV industry chain, related to the solar cells into the upstream and downstream products.

Shopkeeper magnetism related parties: "The company put into production lines in March and April, the third production line is expected to put into the third quarter, a total of five production lines." It is understood that the first solar cell production line started production in March, the current full load condition, the major suppliers of solar energy manufacturers in Zhejiang province, monthly income of 1,000 million, due to the beginning of the cost of inputs and scale advantages, low-margin, mass production after the current industry average net profit margin of about 10%.

Zhou Tao, the Great Wall Securities, said: "The solar industry profits volatile over the past few years, in 2009 also by the financial crisis, a quarter of a collective loss, some loss in Q2 because 96% of exports of solar panels, and mainly in Europe, if analysis of domestic solar energy companies, mainly to see the European market, while the euro exchange rate fluctuations, risks to the export-oriented enterprises. "Jun Ma, chief economist at Deutsche Bank, said central bank Deputy Governor Hu Xiaolian published a report entitled "managed floating exchange rate of three points," the article said the Chinese government to further promote market-oriented exchange rate formation mechanism reform, the determination and confidence. Because of the impact of exchange rate fluctuations, therefore, domestic production of solar panels will increase the company's future performance creates uncertainty. To export enterprises, to increase European demand uncertainty.

Donghai Securities predicted the electronics industry researcher Yuan Cheng, shopkeeper magnetism in 2010, 2011 and 2012 EPS was 0.55 yuan and 0.69 yuan and 0.86 yuan, based on company fundamentals and good future prospects for the development of new energy, to give 30 times 2012 PE, the target price 25.8 yuan.

However, the Great Wall Securities analyst Yuexiong Wei pointed out that "Although the shopkeeper magnetism 873 million yuan investment in the construction of 300MW crystalline silicon solar cells, etc., but with the current companies listed in the U.S., Suntech, LDK, in comparison, there are still a gap. "This is to be the company secretaries to WU Xue-ping said: the company's risk from those who he is later involved.

Beautiful first-half performance of photovoltaic polycrystalline silicon business in the second half, "Warrington"

Beautiful first-half performance of photovoltaic polycrystalline silicon business in the second half, "Warrington"

According to Wind Statistics, as of July 22, the concept of domestic PV 47 listed companies to disclose results of the first half of this year, 26 Express or forecast, of which forecasted up to 21 companies, accounting for 80% .

Analysts said the first half of the growth performance of the enterprises are silicon photovoltaic or battery business, because the first half of the low cost of the product price has been lifted. With the price of polysilicon this year, rebounded in July, is expected in the second half, especially high purity polycrystalline silicon polysilicon manufacturers market is about to come.

First to benefit middle and lower market rebound

It is understood that, since March of this year, the international PV market showed a continued warming trend, solar wafers, cells of different degrees of price rise, which in March, prices rose as high as 20%.

Many downstream manufacturers of photovoltaic surprised to find that in polysilicon prices continued to slump at the same time, the price of photovoltaic products a certain level of recovery in the first half of this year's performance and gross margin are expected than expected. LDK official said, the international PV market to pick up orders will continue to support the full battery of silicon, while the price has improved, multiple factors favor the performance of the company's performance.

Data show that the first half of forecasted PV 21 listed companies, CSG A first half net profit of 636 million yuan, an increase of 143.51%. Dah Sing the first half of the new material is expected to net profit of 65 million -7200 million, up 126% -150%.

International agencies have forecast estimates that by 2010 the global solar market will reach 12.2GWp scale. Solar Energy solar market in 2010 to calculate the amount of approximately $ 30 billion.

A good international environment for domestic solar companies to eat "assurance", and some companies began to expand production at the same time, the market will attract more investors to enter.

Industry experts optimistic about the photovoltaic industry boom of the second half, second half of 2010 or 2011 will be officially launched economies of scale and vertical integration of the competition.

Polysilicon in the second half bullish

In the photovoltaic industry chain downstream products rose a certain extent, the market began to pick up the trend of raw materials delivered to the PV industry polysilicon. July of this year, there is a clear international polysilicon prices rose. Polysilicon prices have 50-52 dollars / kg up to 60-65 dollars / kg.

A domestic PV manufacturers that the PV device market now than in 2008, expanding at nearly double the polysilicon production capacity to expand up to more than 50% in 2008, this year the whole industry full of photovoltaic industry production, by the PV industry and semiconductor Industrial demand-pull double polysilicon supply and demand situation is tight again.

The second half of this year, the scarcity of high-quality production capacity will support the corresponding prices. LDK official said, is expected to purchase polysilicon from the company's point of view, high-purity polysilicon shortage is already evident signs of expected short term is unlikely to change this situation. First-tier manufacturers in many industries expect polysilicon prices will gradually rise to 70-80 dollars / kg.

At the same time, for wafers, cells, components suppliers, because polysilicon prices, "low cost, the price rise," the good times end, the industry worried about the second half of the cost pressure. The polysilicon producers in the second half due to tight supply and demand and the harvest may be a better performance.

It is understood that in the first half the price of polysilicon in the doldrums, Xinguang output of the first quarter of 2010, only 180 tons, up by 23.88%, loss of 23.71 million yuan. Polysilicon prices to regain the recent rally, the second half to help Xinguang rebound performance.

But some analysts believe that, because of China's polysilicon production capacity surplus last year of the shadow, the overall price of polysilicon is expected to rise sharply unlikely. And many manufacturers of photovoltaic River also said if the rate of rising costs too, is bound to further downstream transmission.

Solar-cell factory at the end of the second half of the rise and fall offer into key operational

Solar-cell factory at the end of the second half of the rise and fall offer into key operational

German solar subsidy announced that the latest case, the solar industry believes that actual demand will start in Germany, the most worthy of observation that is the price trend in July, once the price is not so down, over the end of July, the majority of companies believe that the price of solar is unlikely to again bargain, solar-cell factory in the second half is expected to sit back and relax. However, if the price appears loose in mid-July, the economy's trend will test a low quarter by quarter.

Previously by the Bank can not estimate the rate of lead lending freeze, and the investment rate of return (IRR) and difficult to estimate the system case of delay, all because of expectations of the new German assistance was announced after the official launch, the solar industry said that the July price trend will also be a reference to the most important indicator of the second half.

Solar industry said that the European market in the most mature of the German solar industry supply chain influence high in Germany to launch a new subsidy cases before the majority of German industry is actively towards non-German system market, but still retains a considerable inventory ratio, followed by Germany's decision to wait after a new case to complement the operation, which also includes a number of international module plant in Germany, large warehouses, waiting till after the case was sold in Germany.

Once in Germany under the third quarter after cutting 13% of the subsidy rates, market demand in Germany fell more sharply than expected, estimated German industry and within the international plant inventory positions, will be forced down to non-German stock market to reduce inventory This will lead to an overall impact on the market again, especially some quotes, I am afraid to face the impact of a single grab bargain.

Once the price started to decline in July, the price estimated in the second half will follow continued to decline. While Germany will be cut in the fourth quarter, 16% lower subsidy rates, but rates for the third quarter with only a difference of 3 percentage points, if prices continue to fall, then consumers will have expectations, after all, prices decline follow the installation costs down enough to make up for season 3 and 4 the gap between the subsidy, which will lead to the actual needs of the action falls in the fourth quarter.

However, if the demand spread to Germany than to imagine a small, German industry without strong inroads into non-German system market, or non-German market is in fact a considerable amount of appetite enough to absorb the fall of German industry goods, grab a single, multi-supply and demand in the adjustments, so that prices will remain the some stability.

Solar industry analysis, the current price level, if you can last until the end of July, the probability estimates in the second half again haggling is not high, because the market adjustment mechanism is an effective response to the current price level has been able to light up market share 5 percent of the German market after the subsidies cut under the impact, people expect falling prices is difficult psychological health, but also must consider the fourth quarter to cut 16 percent subsidy on the next, hoping to take action to install the very high government subsidies chances will increase. 4 quarters battery industry to "sit back and relax", no longer worried about price competition issues.

Taiwan-based industry, including Motech, Yu Jing, Sun Division, new solar, and other benefits through, part of the solar cell factory in the third quarter from the spot market price per watt in the second quarter jumped to $ 1.4 $ 1.35 or more, mainly due to from Taiwan-based solar cell industry by non-German markets, including Italy, France, Czech Republic District orders blessing, the recent release of Japanese single most obvious Outsourcing orders.
