Taking care of your laptop's battery

Taking care of your laptop's battery
Via: microsoft.com
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.

Which new investment to be funded by a wide 13 million and R & D team to Fosugufen invested 500 million yuan, according to extensive research and development results of new revenue to invest 40%, Fosugufen and R & D team is divided into a total of 60%.


Li-ion battery integrated into the flight program faces five major risks


Integrated into the fly (002 190) has issued a notice of private placement fund-raising projects face the risk of making the top five tips. Previously, integration into the flight have been disclosed private placement program, the company intends to fund-raising not more than 1.02 billion capital increase will be used in aircraft construction lithium ion battery project.


Notice that the lithium-ion battery market capacity project faces risks, construction risks, competition risks, technical risks and risk management. Lithium-ion battery are high-tech products, the market is still in growth stage application stage.


Meanwhile, the main products used in battery cathode material lithium iron phosphate process due to technical and other reasons, few domestic producers, production capacity is limited. Although the relevant domestic enterprises to continue this increased investment, but completed the construction of the project and after it reaches its design capacity, lithium iron phosphate cathode material development of the industry may still limit the supply of raw materials in the aircraft lithium, and its business to a certain impact.


Friends called for battery recycling to protect the environment


As wireless technology to lower prices, more and more popular wireless product. But because the power supply for technical reasons, the wireless mouse must be equipped with batteries, with the increased use of battery recycling on the fore, some enthusiastic early users called for battery recycling systems make the trip, let's take a look at our wonderful friends with the analysis.


Pollution and waste batteries process has become the social focus of most environmental concern. State Environmental Protection Administration of Science, Technology and concerned that with our type of battery, production and use continues to expand, the number and types of used batteries has also increased. Used batteries contain mercury, lead, cadmium, nickel and other heavy metals and acid, alkali and other electrolyte solution, and the ecological environment of the human body have different degrees of damage. It is understood that one of the ecological environment on human health and harmful, included in the list of hazardous waste control of waste batteries are: mercury cells, mainly mercury oxide batteries; lead-acid batteries; cadmium batteries, nickel-cadmium battery mainly.


Today, electronic waste disposal has been the focus of public attention, the majority of users are also welcome to offer words offer, a better environment for our contribution to a force.

5 trillion stimulus to guard against the new energy industry overcapacity

5 trillion stimulus to guard against the new energy industry overcapacity


Industrial development in China's history, "step forward" and "excess capacity" is always go hand in hand, will invest in the next 10 years, five trillion yuan effort to develop the emerging energy industry has been true. Restructuring of the national economic restructuring, development of low environmental-friendly industry in the context of the prospects of new energy industry is looking on. However, how to balance "speed" and "quality" of the relationship between, it has been a problem.


Policy: the emerging energy industry planning has basically taken shape


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.


Familiar with the previous "new energy plan" is different from the National Energy Board will be planning the final 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.


Planning, not only includes the advanced nuclear power, wind, solar and biomass energy resources in these new development and utilization of traditional energy sources will also be important to upgrade the first change, including clean coal, smart grid, distributed energy, new car energy and other industrial application of technology specific implementation of the path, the scale of development and major policy initiatives. In order to achieve non-fossil energy sources by 2020 target of 15%, the size of nuclear power to at least reach 75 million kilowatts, while the hydropower installed capacity will have reached 380 million kilowatts, of which 330 million planned for conventional hydropower, 050 million plan to build can plant. The use of other biomass should scale more than 2.4 million tons of coal.


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, the plan implemented in 2020 will greatly reduce the excessive dependence on coal demand, can reduce sulfur dioxide emissions that year about 780 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.


Back in September last year, President Hu Jintao at the UN summit on climate change proposed for 2020 non-fossil energy accounts for a proportion of total energy consumption about 15%. In December, Premier Wen Jiabao climate change conference in Copenhagen announced to the world by 2020, China's carbon dioxide emissions per unit of GDP decreased 40-45% compared to 2005. Building low-carbon society, development of new energy is the trend, but also a long-term future of China's basic national policy, in order to achieve a solemn commitment to China's foreign, National Energy Board is organizing the units to "five" energy plan for the work, its emphasis will focus on the development of the proportion of non-fossil energy and carbon emission reduction to start two goals.


According to preliminary calculations, the planning period increased the cumulative direct investment of 500 billion yuan, an annual increase of output value of 1.5 trillion yuan, an increase of 15 million jobs in the community. So the next 10 years energy industry will enter a new stage of rapid development, room to grow quite broad, and likely the birth of a large number of new blue-chip, high-growth stocks in the future one of the main areas.


Problem: both "big step forward" and avoid "excess"


In policy and market the "double-sided optimistic", the new energy industry seems to deviate from the explosive growth in a predetermined orbit. Industrial development in China's history, "step forward" and "excess capacity" is always go hand in hand, how to balance the relationship between, it has been a problem.


Statistics show that currently there are 18 provinces and cities have been put forward to build a new energy base, or the new energy as a pillar industry to develop, this rush to develop not only a waste, it will also affect the orderly development of the entire industry. When the whole world for the layout of the new energy and renewable energy industry around the corner, puffed up with pride when there is a sound not be ignored: "No rules can not be into the surrounding area, the blind expansion of the momentum must be vigilant."


Now, the rapid development of China's new energy industry, individual industries and even a "blowout" of the momentum. Statistics show that China's PV industry annual growth rate of the past five years nearly 150% growth in wind power is doubled. As of 2008, China is the world's largest producer of solar photovoltaic cells, the fourth wind power country. But this "prosperity" hidden under there: some local governments and enterprises blindly launched a new energy projects, or duplicate construction industry chain, resulting in some of the industry has just started, had already appeared or blindly follow the trend of unbalanced development of the precursor.


China Investment Advisory Network issued a report, to wind power, for example, as of 2008, China's total installed wind power capacity of 12.2 million kilowatts, and total network capacity compared to 894 million kilowatts, which means that nearly 28% of at least wind power equipment has been built to be idle. This is reminiscent of recent years in China, including steel, cement, coal and other traditional industries to expand and adjust the capacity of the blind structure of the facts.


In fact, a simple high productivity is pretty harmless, but more serious problem is the production capacity over the remaining hidden in some production processes are often not high-tech, simple process repeated and so on, which means high-speed operation of the machine not only failed to produce more profits, but consumes a lot of production. If a bear new economic growth point of the industry, launched the beginning of the hidden from the low-level redundant construction and overcapacity in the shadow of the new industries to take off the way it is set back a huge regret.


China's National Energy Board of new and renewable energy Shi Lishan, deputy director of the wind power plant in Jiangsu Province recently research pointed out that China and other new wind power and solar energy in recent years, rapid development in production, but still the corresponding grid construction to be improved, from the rational allocation of production and use is still some distance.


In fact, many of the key components of new energy production technologies still rely on imports, and these techniques have been the United States, Germany, Japan and other countries a few companies a monopoly. For example, the absence of core technologies, domestic enterprises can only be in the lower reaches of the solar cell, battery components and other aspects of production. In China, the so-called polycrystalline silicon and other new energy industry, but it is still in the low-tech, low-level redundant construction phase, in the downstream industry chain.


Distribution: one-fifth of investment in the auto industry


Institute of brokerage analysts believe that additional 5 trillion of the huge investment in new energy industries, is expected to have at least 1 trillion will be allocated to the new energy vehicles, but this time in addition to the vehicle, the battery to power the core a very optimistic about the auto parts industry, a segment of industry.


"The battery is new energy automotive industry chain, the most important and most valuable part of an investment." Hongyuan Securities analyst Wang Jing said. Battery is the core of new energy vehicles, the most critical components, as predicted lithium-ion batteries will soon become a mainstream alternative to nickel-hydrogen batteries power batteries, lithium batteries power the new energy vehicles for demand-pull as the brightest body focus. Clearly, the lithium-ion battery, motor, electronic control and other related industrial chain of electric car companies will face even greater opportunities for development.


Zhang Xiaoyu, chairman of China Society of Automotive Engineers introduced, the current electric cars are the development of new energy vehicles subject, and key technologies of electric vehicles, including batteries, motors and electronic control of three parts, which is the most central parts of the battery. In these areas are under development in our country, not to the industrialization phase. Unfortunately, however, the current core component of our battery positive and battery separator, 80% are imported.


He said the battery's high import rate of the core components to the development of new energy vehicles in China has sounded the alarm. China is the world's most resource-rich countries of lithium, with the development of battery power resources. Happily, our country has begun to attach importance to the development of battery power, especially in battery-based technology investment and increasing common.


China FAW Technology Center director, said Li Jun, the Chinese government's investment in electric vehicles is very large, and very seriously. New energy vehicles or electric vehicles can not solve China's pollution problem locally, even if electricity is sent to the coal, not the low-carbon economy, but after all it is local, it can solve the pollution problem, can solve the problem of energy transport . But the future is not very large as an industrial leap, this also depends on our own for the automotive industry technology level of certainty.


Interpretation: "5 trillion" and "4000000000000" What is the difference


5 trillion! Is indeed an exciting figure, less than the financial crisis, "2009 economic stimulus package of 4 trillion" even more. Well, this 5 trillion of new energy industry planning in the end mean? And 4 trillion industry stimulus plan different?


The industry believes that this "5 trillion," and 2009 "4000000000000" is quite different. Market analysis, the "5 trillion," focuses on long-term effects of new energy investment, short-term stimulus to economic growth is far less effect in 2009, "4000000000000", so the stock market response is not so strong.


From 5 trillion of new energy investment planning time point of view, across from 2011 to 2020, span the time period of up to 10 years. Equally to the annual capital investment of far less intensity, "4 trillion." Meanwhile, the "5 trillion," a state for the new long-term energy sector development plan, not the immediate macroeconomic stimulus.


Dean of Economics, Fudan University, Professor Sun Lijian that China should seize the new round of global industrial restructuring opportunities, the initiative to a new industrial restructuring, including new energy, low-carbon economy, the concept of the industrial environment. In addition, China's foreign trade should be guided, for industrial upgrading. Exports, to encourage high value-added exports.


The point and purpose of the policy implementation is different from 4 trillion in 2009, is introduced in the international financial crisis, designed to rapidly stimulate the economic recovery has stabilized, inhibited macro-economic decline. The 5 trillion of new energy investment plan in the economic recovery trend has been set, enter the security macroeconomic growth, structural adjustment and development stage, are long-term economic structural adjustment range.
