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.

New Citroen C-Zero electric car

New Citroen C-Zero electric car

The French car manufacturer Citroen will launch its C-Zero electric car at the end of 2010 in the car market. The electric vehicle has the Japanese small-car Mitsubishi i-MiEV as the base. In Japan, the electric car can already be bought for about four months. The Citroen C-Zero has room for four persons and has a top speed of 130 km / h. The range on one battery charge may be up to 140 kilometers.

A few years ago, the French car company, with the Berlingo Electrique First had already developed a first electric car and more than 5,000 copies. There currently is not known at what price the small car hit the car market. The Schazungen to the purchase price will amount but well over 15,000 to 25,000 euros. Every car manufacturer is working on the development of electric cars but only if the price and the range agrees it can be a success in the auto market. A purchase price of 10,000 to 15,000 euros should be quite possible with the use of appropriate modern technology.

iPhone3G battery life

iPhone3G battery life

If you do not have enough battery life, then the function of a cell phone, even then strong, in fact nothing but a Dragon of the technology. Therefore, popular in the Apple iPhone 3G handsets in battery life and standby time performance, naturally, many people paid much attention. According to the official publication of the data shows, iPhone 3G handset in standby time and talk time than the first generation of products is a marked improvement, Bingju in to achieve theoretically the 10 consecutive hours of talk time and 300 hours of standby time. So what is the reality of these? We take a look at this famous site PCworld specific test results conducted by it.



For the Apple iPhone 3G battery life in the performance of, PCworld mainly through 3G mobile phones and other similar cases in the same length of continuous talk time compared to the way to arrive at the battery life of iPhone 3G handsets are pros and cons conclusions. After and take the test, including Palm, Motorola, Samsung, Pantech Duo, AT & T Tilt, LG and HTC, etc. 10 to support 3G network, smartphone comparison, Apple's iPhone 3G the average talk time of 5 hours 38 minutes results become leader, its battery life than the other 9 kinds of 3G smart phones, ranked No. 1. Participate in the test in 9 of the 3G smart phone, only the Samsung Instinct, HTC Touch Dual and the LG EnV 3 phones of continuous talk time over 5 hours, which results Samsung Instinct and iPhone 3G closest, reaching 5.33 hours. HTC Touch Dual and the LG EnV were 5.18 hours and 5.04 hours.



As for the other to take the test of 3G smart phones are not continuous talk time of 5 hours, the worst performance of Palm Treo 750, or even continuous talk time less than 4 hours. It is worth mentioning that just opened at a time when 3G networks, 3G mobile phone standby time, once seen as factors impeding the development of 3G technology. In fact 3G network itself is a notoriously power-hungry, although 3G phones in the standby area has made great strides, but still with the expectations of the people there is a certain distance. In addition, it is also a 3G network technology, but AT & T operating WCDMA / HSDPA network and the Sprint and Verizon's CDMA2000 1X EV-DO network in energy consumption or there are some differences. Which, WCDMA / HSDPA networks as voice calls as data tasks are also through mobile broadband network transmission, so the power consumption relatively more. The Sprint and Verizon's 3CDMA2000 1X EV-DO network technology to transfer data only task, voice calls using regular CDMA network is, so in theory a number of more power. In other words, iPhone 3G use more power in the WCDMA / HSDPA network in the case, the performance of its battery life is still better than other phones, Apple Zheci speaks on the machine's battery life improvement is effective in .



Incidentally, is that for many users complained about the "paste and copy" and GPS navigation capabilities, Apple iPod and iPhone marketing Greg Joswiak, vice president of the explanation is still not on the "copy and paste" feature on the iPhone, Apple The functional development will have its own list of priorities, Apple has so far been strictly in accordance with the list of priorities to turn development. So, iPhone should be in future software upgrades to add "copy and paste" this feature. Second on the iPhone's GPS antenna has claimed too small to achieve route planning (turn-by-turn) navigation application functionality. Greg Joswiak pledge to continue to improve, and look forward to developers to make things that surprised us.

Britain developed a micro-engine is expected to replace the battery

Britain developed a micro-engine is expected to replace the battery

June 17, University of Birmingham announced that manufacturing and mechanical engineering university college lecturer, Chinese scientists led by Dr. Jiang Kaichun research group developed a micro-engine is only a few millimeters in size. Do not look at this small enough to be placed on the engine cover nails look like much, but the energy provided is 300 times that of ordinary batteries.

To understand the results of this study the situation, the reporter interviewed Dr. Jiang Kaichun.

About their research results, Jiang Kaichun showed great interest. He says that when they designed this engine's main purpose is to replace the traditional battery. Since the battery 发明, despite the miniaturization of electronic devices and portable and has played an important role, but the charge capacity of batteries is limited, so that electronic equipment Wei Liao continued work Bixujingchang replace or recharge in energy Persistence and Lianxu Xing Gong Ying there are some restrictions on gasoline and other fuels in this regard carbohydrates showed a clear advantage. In the development of the engine before they have specialized in different types of batteries and fuel were compared to results found in the weight of the same case, gasoline, hydrogen and other fuels to provide energy carbohydrates, 300 times the average for the battery. This means that the same is to supplement the primary energy, using micro-motor-driven device, battery-powered device than a much longer working hours.

In addition, it has been calculated to create the energy consumption of a battery than the battery itself provides 2000 times the energy of a large, if the processing of used batteries consider the energy consumption, then the battery life up costs. In contrast, micro-engine is much simpler, as long as it is added to a fuel, it can continuously work months or even a year or two. Not only eliminates the need for frequent battery changes or recharging the battery trouble, and the device itself could be more compact and lightweight.

On the engine design and manufacture, Jiang Kaichun said micro-engine manufacturing is very different from conventional engines. Conventional engine is usually full of noise produced by the plant in, but micro-engine is in the universities and research institutions in the clean room finished. They are now developing a kind of micro-internal combustion engine, this engine developed by U.S. scientists in different micro-turbine engine, the internal temperature is much higher. In order to withstand the engine running as high as 1,000 degrees Celsius resulting heat, they selected materials in the manufacture of alumina and silicon carbide. Both materials can be resistant to temperatures above 1,500 degrees Celsius, which was provided to ensure the safe operation of the engine.

As the micro-engine compact, and some internal components only a few microns, so the production process, they have adopted similar with the production of large scale integrated circuit technology. The difference is that required components do large scale integrated circuits as small as possible, but use the same process of production engines, you need bigger parts as possible. Because of fuel combustion in the engine requires a certain space, space is too small will not ignite the fuel, which requires the engine components to maintain a certain size. To achieve this, they use a lot of new technology. One of the most unique features is their "big thick layer of light plastic processing" technology. Using this technology, and now they have to process the material thickness is about 1 mm, which is very advanced world. In order to meet the needs of different devices, scientists can also output power of this engine to adjust. Approach is not a production of engines of different sizes, but the number of the same specifications as the engine output to connect different energy. For example, for mobile phones provide enough energy may be an engine, providing power for the laptop you need to put together a number of engines to work Caixing.

Micro-engine wide range of applications, in addition to mobile phones and portable computers can replace the battery, the military, medical and engineering manufacturing and other fields have wide applications. For example, with the increase in portable electronic devices, this should be traveling light soldiers will now have to carry more than 30 kg backpack in front of the war, including at least 1 / 8 load is designed to provide energy for the electronic equipment batteries. Some used for reconnaissance and liaison aircraft and micro-micro-robots as they have to carry heavy batteries and their role in severely affected. If these heavy batteries for micro-engines, their efficiency will be greatly changed. In the medical field, this engine also has a vast battlefield. Scientists, they can be installed in the diabetes and heart disease patients with medical devices, using them to provide lasting power, timing in vivo delivery of insulin for diabetics or people with heart pacemakers to provide energy. In addition, pharmaceutical, chemical manufacturing and processing, micro-mechanical components, this engine has great potential.

Therefore, Jiang Kaichun this engine is very optimistic about the prospects for development. He believes that this research is likely to first use the mobile phone industry. With the constant improvement of engine performance, six years later, the laptop computer and mobile phone battery will be gradually replaced by micro-engines, which will supply energy for portable devices have a profound impact.

Fuel cells and AuPt catalyst

Fuel cells and AuPt catalyst

Committed to fuel cell technology, efficient catalyst for innovation and advanced AuPt debut

Hitachi Maxell has developed a particle diameter of 2 ~ 3nm, and Pt (platinum) could result in unit area compared to about 4.8 times the current AuPt redox catalyst synthesis. At present, the solid polymer fuel cell air electrode (cathode) redox catalyst used generally to use more to carry on the carbon support on Pt catalyst.

Reduce the Pt particle size and increased surface area will help improve the catalytic activity, also add in the Pt Fe, Co and Ni and other metal elements can also enhance the redox activity. However, the problem is near the electrodes for fuel cells was strongly acidic, Fe and other metals dissolved in acid reaction in the power generation process prone to be dissolved away.

The Hitachi Maxell has developed a will not easily soluble in acid Pt Au added to the material. Difficult to form the alloy Au and Pt. Easy to grow into larger Au particles with the characteristics of hard synthetic particle diameter less than 5nm. The citric acid as a reducing agent, the temperature at 100 ℃ to the formation of Au and Pt AuPt alloy, developed only 2 ~ 3nm particle diameter of the catalyst. X-ray refraction analysis, confirmed that Au and Pt alloy structure is incomplete.

It is reported that the development of AuPt catalyst with Pt catalyst, in the standard hydrogen potential of 0.6V, the unit area was about 4.8 times the redox current. Hitachi Maxell that, Au and Pt alloy of incomplete structures and particles helps to achieve high activity.

Carrot and stick

Carrot and stick

The revamped S-Class is set to hybrid and more fuel efficient engines. The fact that the Stuttgart flagship for "Rainbow Warrior" mutated, is not expected. Is already secured by the newly revised versions of top-AMG and the mass-market U.S. and China. kd186 battery

When the new BMW 7 Series came on the market, the S-class suddenly looked very old. In terms of assistance and high-tech gimmicks, the Munich Stuttgart its competitors had overtaken the right and left. Now wants to strike back and make the revised Mercedes S-class as was the E-Class to a "thinking with whom the driver."

Presented were the new cars at the Shanghai Motor Show. There are a few visual retouching, for example at the grill and the headlights (now standard with bi-xenon technology), but above all a lot of new electronic helpers.

These include a high-beam assistant that varies the beam without blinding the oncoming traffic, a night vision system with pedestrian detection and lane-assistant. He warns the driver with vibration on the steering wheel when a lane marking without signaling runs over. tc030 battery

Lane Warner, there are also other manufacturers, but Mercedes wants a particularly sophisticated version developed: the electronics to detect whether the driver has inadvertently or deliberately left his trace. "The warning is not so if the driver accelerates, for example, before a passing maneuver or when driving on the highway when it brakes hard or directs in a curve," says Mercedes.

Also new is an "attention-Assistant is:" Does the electronics Lenkmuster unusual, it closes on a fatigue of the driver and chases a tone through the cockpit. Other high-tech helper is a system similar to BMW and Opel with a windshield camera reads signs and inform the driver in the jungle of signs on the valid speed limit.

The navigation screen is optional with a "SplitView equipped" technology. This driver and front passenger can have different functions: while the driver sees, for example, the map of the navigation system, the passenger on the same screen simultaneously watch a movie from DVD.

The main market for the new Mercedes S-Class is China. Not least because of the Swabians their automobiles figurehead at the Shanghai Auto Show for the first time presented to the public. "Nowhere else we sell as many S-classes, such as in China," says Ulrich Walker, Daimler CEO for the Asia Pacific region. Last year, China sold 14,000 S-class. hd438 battery

"Dreams about in China, any successful businessman. Only if you drive an S-class, one has "done it, says Lu Yuedi, successful owner of the real estate company Xidi as his marketing department that formation would have put into the mouth," In 2003 I had my first S-Class, S 350s purchased. Now I have a S 500, S 600, and two old S-class. "

Lu Yuedi is just 50 years old and is one of the league of self-made millionaires, the big cities like Beijing or Shanghai impress their mark in recent years. He also drives luxury cars from BMW and Porsche. But the day's work he performed alone in the back or at the wheel of his S 600 L.

The S-Class, together with its main competitors BMW 7 Series and Audi A8 luxury sedan in the upper ten thousand. Many are waiting for the new model and rub at the sight of the new model has the hands. "I will soon," still buy a S 65 AMG and Maybach, is proud to Lu Yuedi log as proof that his business is in the real estate world, seemed splendid.

In contrast, the S-class interest in Europe will focus on many of the diesel versions. In the United States are the top models S 550 4Matic, S 600 and the AMG models at a premium. From August, the new generation has to get with a hybrid drive. The ecological figurehead of the revised S-Class, the S 400 hybrid with lithium-ion battery that, according to factory specification achieved an average fuel consumption of 7.9 liters per 100 kilometers. lenovo thinkpad x60 battery

Interesting, especially for frequent travelers might be the S 350 CDI BlueEFFICIENCY (235 hp), which should be satisfied on average with 7.6 liters of diesel. Overall, the engine range include, in addition from the Hybrid eight gasoline and diesel engines, including the eight-cylinder Diesel S 450 CDI (320 hp), the base petrol engine S 350 (272 hp), the two eight-cylinder S 450 (340 hp) and S 500 ( 388 hp) and the top model S 600 with a 517 hp twelve-cylinder biturbo engine, with the luxury saloon accelerates in 4.6 seconds from 0 to 100 km / h.

The most powerful S-Class models, but as usual Affalterbach and listen to the names S 63 AMG and S 65 AMG. The V8 version brings it to 525 hp and a torque of 630 Newton meters, the sprint from 0 to 100 Km / h in 4.6 seconds. The S 65 AMG has a six-liter V12 engine with dual turbo under the hood and can come up with 612 hp and 1000 Newton meters of torque.

The acceleration from 0 to 100 km / h in 4.4 seconds. AMG trim, alloy wheels, double-end exhaust pipes and special daytime running lights mark the steam hammer with a star. That should please both S-Class-Fan Lu Yuedi.

The sports suspension, the AMG sedans equipped with a side wind stability. The work is varied within milliseconds by a wheel load distribution, drawing upon the yaw rate and lateral acceleration sensors of the ESP.

Further, a system called "Torque Vectoring Brake" is standard on board should: When cornering, a targeted short braking intervention at the inner rear wheel a "defined screwing" effect of the vehicle and thus allow more control in heavy cornering. lenovo x60 tablet battery

These systems are also available for the normal S-Class. The standard equipment of the two AMG-force air-conditioned hum sports seats, leather upholstery and a seven-speed automatic (five-speed automatic includes the S 65 AMG). The S 63 AMG is with a long or short wheelbase, the S 65 AMG long version only.
