How to extend the laptop battery time
1. The screen brightness to reduce. However, power-hungry LCD screen brightness can effectively be extended to reduce the use of time.
2. Open SpeedStep and PowerPlay power-saving features such as. Now the notebook Inspiron 1720 battery,Inspiron 1721 battery processors and graphics chips have lower operating frequency and voltage to extend the use of time functions, open the appropriate option can significantly extend battery life.
3. The use of hard drives and CD-ROM of the spin-down software: such as NERO DriveSpeed, PowerBooster can reduce software such as CD-ROM, hard drive speed, etc. can also be effective in reducing notebook power consumption.
4. Make good use of standby, sleep and other functions. As a long time without a computer, allowing notebook standby or hibernate, saving electricity extended the life of the computer.
Here are some proper use and maintenance of the battery approach.
(1), bought a new fully charged battery at least once a power, and then into electricity, the second charge after official use.
(2), when the notebook computer when the indoor use of AC is best to remove the battery so often in charge state.
(3), charging is best off the laptop, the battery is fully charged, do not unplug the power in the charge half-way.
(4), charging is completed, the battery should be allowed to rest for 30 minutes re-use, this can keep the battery's health.
5, if the long-term non-use batteries Inspiron 6000 battery,Inspiron 630m battery, it will automatically power loss; if the battery state of a long period of no electricity, the general index of more than one week, it will affect its performance. Therefore, even if the battery is temporarily not used, it's best every month or so, once it is fully charged, it is in a state of war. If it does not use the battery for too long, so long as the battery charge and discharge completely three times, the battery will be restored vitality.
6, at the same time the use of AC and battery-run laptop computers, do not remove the battery, or has the potential to damage the battery, the correct way is to first turn off the computer and remove the battery.
Apple and Adobe the escalation of conflict: iPad into the fuse
iPad refused to Flash
While Apple CEO Steve Jobs (Steve Jobs) said, iPad will bring about changes in Internet browsing, but the iPad does not support Adobe's Flash technology. The news also Adobe shares fell.
Because Flash is widely used on the Internet, so iPad mean that the product does not support Flash out of the mainstream in this regard. According to Adobe data, 98% of the networked computers are installed Flash Player, and Flash was used in 75% of Internet video and 90% of interactive ad.
In the last month, Apple's internal meeting, Jobs to employees that Flash "is full of Bug", and that in most cases, lead to the collapse of the reasons Mac computers are Flash.
Of this, Adobe has made through the many articles blog articles back. Adobe noted that, iPad ignored Flash, as well as to provide access to the Internet experience for iPad questioned. Adobe also said that have been developed that can be used iPad of Flash. Adobe CTO Kevin Lynch (Kevin Lynch), said the only question is "Adobe needs to be Apple's co-operation can the version of the Flash used in iPad, while Adobe is ready."
Apple and Adobe the escalation of conflict
The conflict between Apple and Adobe a long time. Although the two companies is a long-term partners, but Apple's attitude is gradually turning Flash lukewarm. A few years ago, Apple said the iPhone (mobile Internet) will not support Flash. Steve Jobs said at the time, this was mainly due to Flash can not be effectively run on the iPhone. In the iPhone running on, Flash consumes processor resources and not less than when running on the PC.
Adobe acknowledged the problem and said it would resolve the issue. Since then, Adobe has developed a smart phone can run on Flash, except apples, other handset makers have begun to adopt the version of the Flash.
As the iPhone and iPad was the refusal, Adobe has lost a number of growth opportunities. If the user to give up Flash, turned to get Apple to support HTML5 standard, Adobe will face a crisis. Adobe brings Flash did not disclose how much revenue, but pointed out that the software is the company's most important assets.
Some analysts noted that investors will not refuse to Flash on the iPad to make too much reaction to the news, because this issue has yet to affect the performance of Adobe. However, UBS Securities analyst Brent Thill, said: "Wall Street will gradually be aware of this issue."
Because they do not support Flash, iPad will be unable to properly display the site in Flash video and interactive graphics, users will only see one block of white space. iPad will not support the Hulu and other video sites.
Apple's plan to
Apple thinks, Flash is an outdated technology, Web browsers could eventually without installing an external plug-in the case of video. Jobs said that Apple will use the website to provide support HTML5 standard, HTML5's supporters, including Apple and Google.
However, Web developers, said, HTML5 is still under development, has not yet been widely used. Web site developers, CEO of Smashing Ideas, Steve Jackson (Steve Jackson) said: "If there is a large number of user base, we will focus iPad development site. Present our customers, it is not necessary."
Jackson said that, Flash is a web design standards, which in the short term will not change. In order to make your site and games can be iPad a normal use and development staff will develop a separate Web site for the iPad, but this requires additional time and money.
Some critics believe that Apple's refusal to Flash is the App Store in order to better control the development of the application, at least at this stage is. This will enable developers to not be able to iPhone and iPad development of Web-based applications.
Based on historical experience, Apple will stick to their own practice. 10 years ago, Apple abandoned the floppy drive in the iMac, which was aroused great controversy. However, this decision was subsequently proved to be correct.
Ni-MH battery will be policy priorities in support
In the new energy vehicle development strategy in countries and regions all over the world have been based on their assessment of different options, the relevant battery technology research and development and to promote support for taking a different strategy. From the current situation as a whole, Japan and the United States and Europe focused primarily on lithium batteries and fuel cells, but our country as taking into account the resources and technology maturity, in the newly released policy emphasis on promotion of nickel-metal hydride batteries.
"Ni-MH - Lithium-Ion battery - fuel cell," Industrialization Path
In the commonly used three kinds of car batteries, lead acid batteries due to serious environmental pollution has long been out of the mainstream applications; nickel-metal hydride batteries, although the commercialization of the mainstream at present, but the key indicators of laboratory data were lower than lithium batteries, and the basic theory, there is no room for; lithium batteries despite the superior performance, but still can not be guaranteed safety, and the relatively high costs have also hindered its commercial.
Experts predict that the new energy vehicles will be in the "Ni-MH - Lithium-Ion battery - fuel cell" industry-oriented development path. From the development trend and rate, and short-term performance can be realized only nickel-hydrogen batteries, nickel-metal hydride battery technology since the most mature in the next three years, will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel cell-third of the world, 5-year lithium batteries and will be gradually replaced by fuel cells. Battery giant Panasonic and Sanyo also found that the lithium-ion battery can not be replaced in 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-hydrogen battery safety, has reached large-scale production. Lithium batteries also need to continue to research topics, such as security, so take time commercial.
According to Japan's Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion battery will gradually erode the market share of the nickel-metal hydride batteries, the agency predicted in 2009 Ni-MH rechargeable battery-vehicle global market scale than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will fall to ¥ 55,000,000,000.
Ni-MH battery to become the focus of China's current policy support
In our letter to the Department of Public June 25 that the "new energy automobile manufacturing companies and product access management rules", the vehicle according to the new energy vehicles, systems and key assembly technology maturity, degree of perfection of the national and industry standards, and industrial the degree of difference will be divided into initial stage where the development period, three different stages of technology maturity, and give classified management.
In accordance with state regulations, start-products only in small volume production, and only in approved areas, scope, duration and under conditions of model runs, and the operational status of all products for real-time monitoring; development stage product allows for mass production only the approved area, scope, duration and conditions of sale, use, and at least 20% of sales of products running in real-time monitoring; mature products and conventional automotive products, "vehicle manufacturers and product announcement" Management the same way, in the sale and use of the same as with conventional automotive products.
This means that, in China, December 31, 2010, equipped with lithium battery hybrid and electric vehicles will be limited to the sale and use areas, the use of nickel-metal hydride battery hybrid and electric vehicles can be sold and used across the country.
Experts believe that the reason why countries are now the focus from the development of lithium batteries into nickel-metal hydride batteries, the main reason is that nickel-metal hydride battery technology is more mature than the lithium batteries, more abundant mineral resources, the future of new energy vehicles will enable greater access to the commercial phase.
The market demand for nickel-hydrogen batteries to bring 2-3 years of rapid growth in
Nickel-hydrogen battery technology, and industry chain to determine their maturity will be a period of time with the coexistence of lithium batteries, lithium iron phosphate cathode material for lithium batteries makes the emergence of performance and cost advantage has been achieved, but the stability of production capacity deficiencies and the lack of inspection of the actual operation continues to be a part of the new energy discourage automobile manufacturers; In contrast, nickel-hydrogen batteries have gone through years of actual combat, technical and industrial chains are quite perfect, in a short time can be formed on the vehicle's stability and supporting capacity, and therefore can still be a period of time in the new energy vehicles widely applicable.
According to industry estimates, nickel-hydrogen battery market is still expected to get 2-3 years of rapid growth in the next 2-3 years, the "10 City 1000" program, the increasing popularity of hybrid cars and export in overseas markets for nickel and other factors to bring hydrogen-powered battery market demand for strong growth, and when the nickel-metal hydride batteries and lithium batteries are still Nanfenbozhong when the nickel-hydrogen batteries will usher in a short period of rapid growth.
Among them, China has launched a "10 City, 1000" Plan will bring the first batch of nickel hydrogen battery market demand. It is estimated that in the "10 City, 1000" program, about 3200-4000 vehicles, new energy vehicles (including buses and passenger cars) using Chinese-made nickel-hydrogen batteries, within three years, bringing a total of about 3.5-4.4 million kilowatt-hour nickel-hydrogen battery needs.
Taken together, both domestic and export demand weakened after the 2012 nickel-hydrogen batteries will gradually be replaced by lithium batteries.
Keep up the pace of R & D policy
In China's automotive battery production enterprises with a production capacity of nickel-hydrogen batteries accounted for the majority of companies, including Chunlan Group, Ke-li Yuan, the torch high-tech, Hunan Shenzhou, Kane shares, etc., which Chunlan Group is the nickel-metal hydride HEV power battery technology, leading market share in a leading position in the torch high-tech and Hunan Shenzhou has possessed a certain amount of technical base and market position.
As for the lithium battery, most domestic manufacturers do not have the ability to mass production, but the relevant production planning has been implemented, it is expected after 2010 be able to mass production.
Experts believe that, technological advances, China's car prices and the related battery business in addition to promoting the industrialization of nickel-metal hydride batteries, more attention should be put some of the long-term, to devote human resources to carry out power lithium battery research and development, and to maintain the fuel cell technical follow-up, in order to occupy a broader new energy car market ready.
