According to Cnet reported that a new production of liquid cell company received seed funding from Microsoft founder Bill Gates. The company named LiquidMetalBattery (Lmbcorporation.com), it is created by MIT professor DonaldSadoway.Acer BTP-43D1 Battery, I participated in the first half of the U.S. Department of Energy’s Energy Research Projects Agency Meeting (ARPA-E), almost everyone is talking about LiquidMetalBattery company.
Sadoway professor and his team have been working on a stable, low-cost, large models of the grid cells, and their increasing size batteries developed to confirm this idea – from the size of the bullet cups to the size of hockey, to the pizza size, and ultimately to the table tennis table, which is size. Sadoway told us that he plans to decentralized management and some business partners, and the Gates and other companies from the seed money obtained will undoubtedly be used to operate and expand. Cnet said Professor Sadoway leave the company over the past year in LiquidMetalBattery technology consultant.

Sadoway tell us the reason why he would choose to make the liquid metal gate with the battery, because he thought the battery based on liquid metal electrode is more stable, and the shape and size can be adjusted on the line as long as the appropriate cost. “Now we are first and foremost problem is the development costs are too high. We can produce the batteries can be recycled, and can produce the batteries can be used in various fields.” Internal use in the battery based on liquid metal pool of the battery with the use of many independent Instead the concept of unit,Acer BTP-43D1 Battery, Acer TravelMate 220 Battery, Acer BTP-58A1 Battery, acer BTP-60A1 Battery, Sadoway that can produce low-cost batteries.

This project won the ARPA-E690 million in sponsorship funds, Sadoway said the money to help the team improve development speed, but also recruiting more staff, students and postdocs to further expand the company’s operations. The project also received $ 4,000,000 Total oil company’s sponsorship.

In the past few years, Bill Gates has repeatedly talked about and investing in green technology development companies, including venture capital funds, as Khosla limited partner co-investment in nuclear power plants TerraPower. Gates at a meeting last year, also said he would invest in the five cell manufacturing company. LiquidMetalBattery must be one of them. Also at that meeting, Acer TravelMate 220 Battery, Gates said the areas of innovation in the battery “can not be resolved by economic means.”

Mobile wireless charging can be achieved by 2012

According to the Daily Telegraph of September 15, Fujitsu, a Japanese technology company, has created asystem capable of simultaneously charging multiple portable electronic devices such as mobile phones, digital cameras and laptop computers without the need for cable connections。

　　Electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology，said the company, which unveiled a prototype system at the Institute of Electronics, Information and Communication Engineers conference at Osaka Prefecture University. Claiming to be the world’s first of its kind, the technology works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device。

　　The system enables wireless charging at distances of up to several metres, with the ultimate aim of installing public “charging spots” on the streets in order to enable easy charging around the clock. Scientists at Fujitsu Laboratories are planning to commercially sell products incorporating the new wireless charging system as early as 2012 but did not disclose how much they would cost。

　　”This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger,”Acer BTP-58A1 Battery, the company said in a statement。

　　Mobile phone users in Japan can currently top up their batteries using disposable portable plug-in battery-operated devices, available at most train stations and convenience stores. However, phone companies warn prolonged use can damage the phones。

　　The company added: “We are also looking at applying the results of this work to fields other than portable electronics, including power transmission between circuit boards or computer chips, and providing mobile charging systems for electric cars.”

Recently, my colleague Xiao Zhang is addicted to a “game” – a man to adhere to 100 seconds.

But the game play is not easy, nor is the object of the game full screen to avoid bullets that the spacecraft,Hp laptop battery but his sets always carry a notebook computer!

A laptop computer have anything to do with this game? Zhang estimates this question, he would definitely be complaining to you big water. Zhang notebook original one and a half or so to buy time, all aspects are pretty good, not what the big problems, only problem is battery life getting worse over time.

I remember just bought the computer, the notebook sales staff told Zhang life up to three and a half hours, enough to meet with him. Zhang used home sales, said that although not as much, but it can also be stable in three hours, so when the mobile office can not be assured of the full-back adapter to run at. This state lasted for a year, but the second year, the notebook’s battery life began to shrink significantly, dropped from three hours to two and a half hours, and then an hour … … a short period of six months, the small Zhang notebook battery life to short to only be calculated in minutes until the power is almost equivalent to no working ability.

Zhang first laptop too short for some of life does not matter,Hp PP2200 battery,Hp Pavilion dv2000 battery (Hp dv2000 battery), Hp HSTNN-LB31 battery, Hp EV088AA battery, Hp 417066-001 battery is that with the power adapter between the shuttle in a conference room, but the station to the conference room of the distance has become the biggest test of the laptop, whether in the short short run a few minutes from the station conference room and plug in the power, indeed, so Zhang is a headache. He jokingly: “and play” a man to adhere to the 100 seconds “That game is almost 100 seconds then the power does not go to the conference room, would definitely off the … …”

Laptop battery life is usually easier to ignore the problem the user

Chang’s story is not the case, laptop battery life is often the most easy for users to ignore the problem,Hp 417066-001 battery in addition to the design of the battery itself, factors, incorrect use or poor use of the environment caused by the battery life is the main reason for the sharp reduction in .

Today, we come to analyze, how to protect our laptop battery life.

For users, the battery design is the only non-subjective factors change, depending on the product manufacturer, how to choose the time of purchase to a good battery as a prerequisite for life.

Battery looks deceptively simple, but the sophistication of its internal bit as impressive as the core components of the notebook. As the first battery-powered unit, to ensure the stability of output current, but also to both efficient energy output management system.

Hewlett-Packard HP EliteBook P Series interior design long-life battery

Professional-level business notebook HP HP EliteBook P Series batteries, for example, many aspects of it from the battery a full range of functional design and protection. Safety, including fire-retardant casing, heat protection pad, flexible circuit boards, PCA conformal coating, closed barrier layers designed to provide thermal insulation, anti-short-circuit the battery safe use of oxidation environment.

Hewlett-Packard HP EliteBook P Series interior design long-life battery

On the other hand, this battery also has a very intelligent battery management chips, algorithms, and battery charging through the security control unit (BMU), the load imbalance can be found in the battery automatically shut down the battery. Batteries so it can easily by high temperature aging, multiple charge-discharge tests and other options within the core.

It is because of various hardware and software design advantages, the battery can withstand more harsh conditions.Hp EV088AA battery, Hewlett-Packard HP EliteBook P Series batteries used in the design is a good example of starting from the material, with good battery cell technology and battery packages in order to effectively control the battery state, in the face of low-temperature, high temperature environment or an exception to use to minimize the possibility of problems.

Notebook battery is not just a rigid computer components, because of the internal circuit and has a complex chemical composition, making the battery the same as the human body is very sensitive to the external environment. Harsh harsh environment can easily lead to the rapid shortening of battery life, so whether to use or store the battery in the laptop when they need to take into account the external environmental factors.

Storage temperature of 40% state of charge of 100% state of charge
0 degrees 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
40 degrees 85% (one year later) 65% (one year later)
60 degrees 60% (one year later) 60% (three months later)

Save laptop battery life evolved form of idle

The first is the notebook used notebook product itself as a core component characteristics have high fever, so good cooling and ventilation is very important. Try not to place the laptop where heat is not good to use, such as bed, carpet, legs, etc., these areas are likely to cause overheating notebooks, ranging from lead to crashes, while in the burning of the circuit, and the great impact of high temperature on battery life .

Long-life batteries and battery charging capacity of ordinary contrast

Of course, not recommended to use laptops at very low temperatures,Hp PP2200 battery,Hp Pavilion dv2000 battery (Hp dv2000 battery), Hp HSTNN-LB31 battery, Hp EV088AA battery, Hp 417066-001 battery extremely low temperatures will reduce the activity of lithium, reduced battery life.

In addition, the moisture will also affect the laptop battery life, so we saved the best choice when the battery low-temperature drying of the space, and use the laptop during the heat have to do the work.

What laptop battery how to use, on-line can be described as controversial.Hp HSTNN-LB31 battery, But it is undeniable that the use of only the good habits and keeping habits, to let the battery lasting and efficient work.

Battery life and number of charge and discharge are closely related. Common battery design life cycle of approximately 500 charge and discharge in 300 (about 1 year use of time), the battery capacity drops to about 80% of design capacity. Zhang shows that the use of laptop batteries after a year reduction in life is normal, but not the correct use of means to cause a sharp drop in consumption, which is we need to learn a lesson from the.

This is because the battery has a life cycle, so many brands laptop battery components are provided for the 1-year warranty period, ie within 1 year, if the battery life of abnormal attenuation are available warranty.

How to distinguish the current battery life, online there are many third-party detection software, of course, we recommend users to use the brand’s own monitoring tools such as HP and other notebook Battery Check. When that battery capacity reduced to 50% design capacity, and the warranty period can apply to meet the other requirements of exchange. Of course, this battery testing program is also smart battery technology based on industry standard design.

In addition to concern about battery life, we can also purchase long-life battery to ensure that the use period of notebook products. And a battery life of 500 charge and discharge cycles of different, long-life battery charge and discharge times up to 1500 times in 1000 (about 3 years use of time), the battery capacity will be reduced to 80% of its design capacity. At the same time more of these batteries have a long lasting 3-year warranty, including Hewlett-Packard HP EliteBook P series, including some high-end business notebook brand provides the user with such a choice.

To find out about the life cycle of laptop batteries, we finally give the battery used to provide some tips to help you develop good habits of battery use and storage.

- Buy a new laptop, the first three do not need to charge up to 12 hours, because the current laptop battery charging limits have management control chip, when the power will automatically cut off after full charging to protect battery life, avoid overcharging phenomenon .

- Each fully discharged before charging is no need, because it will shorten the battery life of the depth of discharge, it is recommended the remaining 10% can be charged when the battery. In addition, when the battery power is still more than 30% of the best to be charged,Hp Pavilion dv2000 battery (Hp dv2000 battery), because the memory effect does exist. Through the power management software can always check the battery power, and Hewlett-Packard HP EliteBook P Series notebook comes with a battery level indicator in itself, can not even have to check the remaining battery power.

Hewlett-Packard with the remaining power indicator HP EliteBook P Series Battery

- Insert the AC use (plug in power) do not need to remove the battery, as most laptop batteries need to power down to 90% will be charged, while the natural discharge of the battery capacity to achieve this will take two weeks to a month’s time, So do not worry about daily notebook repeated charge and discharge, not to mention damage to the emergency power of data to be greater.

- If you want long-term preservation of idle cells, need to be in dry, low temperature environment, while maintaining the battery charge remaining 40%. Also best to remove the battery used once a month to ensure good state of preservation and the battery life.

- Reduce the screen brightness to prolong laptop battery life notebook,Hp PP2200 battery,Hp Pavilion dv2000 battery (Hp dv2000 battery), Hp HSTNN-LB31 battery, Hp EV088AA battery, Hp 417066-001 battery thus reducing the number of charge cycles.

Power Assistant exclusive HP notebook power management tools

- Use some power management tools, such as Hewlett-Packard HP EliteBook P series are equipped with the Power Assistant, it can even real-time monitoring through the PMC circuit power status of the various components, Hp PP2200 battery and accurate summary of the situation across the company to HPclient Configuration Manager software, and in accordance with need to specify any parts off to extend battery life.

Well, we summed up over how to extend laptop battery life of some of the points, I hope everyone in their daily work to treat their own “good partners”, not the same every day as Sally, “to adhere to 100 seconds,” the

There’s only so much you can expect from budget laptops. Even so, the HP G42-415DX, priced at $529.99 at Best Buy, is pushing it. Like many of HP’s portable PCs, it has a fine look and all the basic amenities you’ll need. But other laptops offer performance that’s as good or even slightly better, Hp laptop battery while costing a fair amount less. Unless you’re really devoted to HP-branded laptops, you can do better than the G42-415DX.

Design
If perhaps a bit subdued, the G42-415DX’s design is nonetheless appealing. Bearing a stem-to-stern tarnished-silver color, it captures light without blinding reflectivity; the textured HP Imprint finish, a triangular pattern across the lid and inside (there’s not even a break on the touchpad), accentuates details with subtle grace. (The pattern is preloaded onto the system’s desktop wallpaper as well,Hp 396008-001 battery, Hp Pavilion dv9000 battery (Hp dv9000 battery), Hp EV087AA battery, which is a nice touch.) The 14-inch display’s bezel and the standard keyboard are both black; the former is glossy and the latter matte, rounding out the laptop’s overall impression of quiet elegance. At only about 4.7 pounds, it’s also one of the lighter low-cost laptops on the market, weighing less even than the 5-pound Gateway NV50A02u (4 stars, $449.99 list).

MoreFeatures
Most budget laptops offer but a simple selection of components, and that’s certainly the case with the G42-415DX. Its AMD Athlon II X2 P340 CPU clocks in at only 2.2 GHz, and is accompanied by an about-average amount of RAM: 3GB. The hard drive, too, is nothing special at 320GB; Hp EV087AA battery, some models that cost less, such as the Gateway NV50A02u, offer even more storage space (in that case, 500GB). Of course, you’ll also have to contend with integrated video: ATI Mobility Radeon HD 4250. A webcam and microphone are located along the top bezel of the crisp, 1,366-by-768-resolution widescreen display.

Perhaps the closest thing to an elaborate feature on the G42-415DX is its HDMI output port, which can be found on the laptop’s edge; joining it there are a VGA out, Ethernet jack (complementing the integrated 802.11b/g/n Wi-Fi), two USB 2.0 ports, headphone and microphone jacks, and a multiformat card reader. On the machine’s right edge are the DVD burner, another USB 2.0 port, and the port for connecting the power cord.

Performance
To be clear, we don’t anticipate that any budget laptop is going to deliver truly barn-burning performance. But we do expect its capabilities to be more or less in line with its price, something that is not the case with the G42-415DX. Its results in our suite of benchmark tests were equivalent to or below those we saw from the Gateway NV50A02u, which costs $80 less, and even the Dell Inspiron IM5030-874B3D (3 stars, $429.99 direct), which costs $100 less.

In some cases, the differences were minor, as with our CineBench R11.5 rendering test (1.77 for the Gateway, 1.22 for the Dell, 1.16 for the HP) or the PCMark Vantage full-system appraisal (4,455 for the Gateway, 3,505 for the Dell, 3,503 for the HP). In Photoshop, the deficit was slightly more pronounced: The HP came in the middle (just barely), needing 9 minutes and 21 seconds to finish our Photoshop CS5 trial applying a dozen filters and effects to an image, with the Gateway taking 9 minutes and 24 seconds to finish, but the Dell requiring only 8 minutes and 13 seconds.

The Dell also slightly edged out the HP in terms of gaming (at 1,024 by 768, with medium details enabled)—8.1 frames per second (fps) versus 8 frames per second in Lost Planet 2; 10.1 fps versus 9.2 fps in Crysis—but both are fundamentally unplayable at those frame rates. (The Gateway, earning 8.7 in Lost Planet 2, is not appreciably better.) If 3D gaming interests you at all,Hp 396008-001 battery, Hp Pavilion dv9000 battery (Hp dv9000 battery), Hp EV087AA battery, you’ll need to drop a few more dollars for a system with discrete graphics.

The G42-415DX only proved demonstrably superior to the IM5030-874B3D in one area: battery life. Whereas the Dell could only manage 3 hours and 12 minutes, the HP with its six-cell, 47 Wh battery held out for a full 3 and 31 seconds—not terrific, but better. Again, however, Hp 396008-001 battery, the Gateway NV50A02u delivers more juice for its lower price: 3 hours and 50 minutes.

Either the Gateway NV50A02u or the Dell Inspiron IM5030-874B3D would make a better cost-saving computer choice than the HP G42-415DX; and if you want something with considerably more power (and better battery life), our Editors’ Choice, the Acer Aspire AS5742-6475 ($599.99 list, 4 dots), will run you only $70 more than the HP. You may have to sacrifice some design elements for the increased potential, but it might be worth it as they’re about all that give the G42-415DX any discernible distinction.
