Laptop has been enchanting charm, a vast number of computer enthusiasts, especially the young to pursue a family focus. The new laptop mostly in million yuan, due to the reasons for the laptop battery of non-biggest names in hard to accept; while second-hand laptop computer is relatively cheap, its function in general can be used to meet the need, and therefore second-hand laptop computer enthusiasts to purchase a minority.

However, the second-hand laptop, after all, is the second-hand goods, is used by others, and its uneven performance, compared with the new notebooks, the biggest difference is the built-in battery should be working hours, and better able to work a little 2-3 hours, poor or even 1 hour is not that, Imagine, such a battery, has just appeared in front of their friends gestures some low-power alarm, how much loss of face. Although the second-hand laptop computers also are equipped with AC power adapter, but if only relied on, and there is nothing different from the desktop dell Inspiron 8600 battery,dell Inspiron 9200 battery? Will lose the significance of the purchase of notebook computers.

In order to play a second-hand notebook computers advantages of moving their own, it is necessary to work on the battery. Laptop battery has been a large “books” fans feel is a very mysterious thing, that it how high technical content, does not. Here is a notebook computer batteries internal structure.

From which we can easily see that, by a number of individual cells in series and parallel together to form a battery pack, combined with the battery protection circuit, they constitute a laptop battery. Whether you use a notebook computer is what the brand, and its built-in battery’s internal structure are similar. If the internal use in accordance with the type of battery to points, most of them can be divided into nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, lithium polymer batteries. The nickel-cadmium batteries, nickel-metal hydride batteries have a memory effect due to the capacity of small and other disadvantages are gradually being eliminated out, lithium-ion battery has a large capacity, small size, light weight, low self-discharge rate advantage has now become a series of notebook computer the mainstream of the battery set.

Second-hand notebook computers because of production age-old, after the use of a few years later, its battery much shorter working hours need to be replaced, various brands of laptop battery shape is different, not interchangeable, in order to buy into the same look and feel, the same model second-hand laptop computer batteries be prohibitively difficult. How to do? Of course, this DIY spirit of the fans have yet to be rattled! After using various means (such as software maintenance, charging and discharging several times the depth of activation, etc.), are invalid or effect.

But our own hands, the charges will not spend more than 50 yuan! Worth a try.

There is a tag line, said: “The biggest operation - completely changed”, I introduce to you today, tends to be scrapped is the right notebook batteries reborn surgery, the charge is not into electricity, reduce the capacity of the battery replaced. “Reborn” is mildly entertaining seems scary, very difficult to like, actually read the contents of the back you will understand, as long as a little with the practical ability of the fans are all successful, I believe you can do a back surgeon , to their notebook computer batteries surgery dell Inspiron B120 battery,dell Inspiron B130 battery.

Material preparation: electric iron, digital multimeter, blade, hot melt adhesives, hot air guns, a number of lithium batteries batteries (as the case may be) and so on, of course, if your laptop is used in the original nickel-cadmium batteries or nickel-metal hydride battery, in order to enhance the battery capacity, are replaced by lithium batteries is also not a bad idea is only a suitable lithium batteries batteries is too difficult to find them. Mail-order single-cell lithium battery, model is US18650, a single-capacity 3.6V 1.35AH, through a certain series, parallel combination, can be combined into different voltage, different-capacity lithium battery, so as to achieve the requirements of your beloved notebook.

Of course, it is possible laptop batteries batteries may not necessarily be such a cylindrical, if it does not work, then you can also buy rectangular lithium batteries, in short, according to your own laptop battery exterior and interior space to choice and decision dell Inspiron E1405 battery,dell Inspiron E1505 battery,dell Inspiron E1705 battery.

The greatest advantage of laptops is mobility, provide the basis for all this is the battery. In the energy-saving technology and battery technology being a time when there is no breakthrough to fully optimize the battery and master the use of a number of related techniques would be helpful. However, laptop battery life is longer, often dissatisfied with the charge, and even shows the battery is damaged, it must pay particular attention to the use of certain skills dell Inspiron 6400 battery,dell Inspiron 640m battery.

First, choose the best time to repair
Laptop battery there is an inevitable part of aging, almost all of the repair methods are trial “deep charge deep-release” principle, in order to ease the laptop battery memory effect. Undeniably, however, the depth of the charge and discharge operation will not be good for the laptop battery itself, is a must not to do this method. If the battery life to merely reduce the dozens of minutes, then care should be taken to this method of operation. In addition, the pool of laptop battery manufacturers has been optimized, there is no self-depth again to upgrade the battery charge and discharge capacity argument. However, exactly when you need the depth of charging and discharging is very difficult to master, after all, every time the electricity consumed are not the same, it is suggested we BatteryMon with this professional software.

BatteryMon is a specifically for the small laptop battery monitoring software, especially for those who are not built-in power management chips and software, machine, it will undoubtedly help a lot of great help. BatteryMon most salient feature is able to discharge curve, and the installation will run automatically. A good performance of the battery will have a very regular discharge curve, as shown, basically a grid for every drop of time are probably the same. If found to have a very unusual beating, then it is necessary for cell “deep charge deep-release” repair.
Second, “deep charge deep-release” of the basic method
Batteries correction is an effective way to deal with aging batteries, in general, the various brands of notebooks will have a dedicated battery calibration software. For example, IBM’s ThinkPad series of discharge dedicated software, recommended for all to use IBM notebook users. But the program need to be repeated three times to get the best results. Download the software and the implementation of discharge, the system will be prompted to create installation disks. Use the installation disk boot PCDOS, unplug the AC power supply prompted, discharge the software will automatically discharge control. When everything after the notebook will automatically shut down, and then we can be connected to AC power for charging, time control in the 9 ~ 12 hours, repeated for 2 or 3 times can be.

For the laptop battery activation, our key software to find a suitable discharge. Unfortunately, if your laptop is not specialized discharge software, you can be shut down in the BIOS and Windows power management features, and then do not run any programs where the battery runs out, and then in the boot state to 80% of charge , repeated a few times also equivalent to manually “deep charge deep release.” In fact, this approach aims to make continuous small current laptop battery discharge, which discharge status in our daily use is unlikely to be achieved, the effect of the discharge and those dedicated basically the same software dell Inspiron 8500 battery,dell Inspiron 8600 battery,dell Inspiron 9200 battery.

Asus and Apple were the most reliable PC vendors in the U.S. during the second quarter this year, according to a survey released by Rescuecom on Tuesday.

Rescuecom, a third-party computer repair firm, fielded the fewest support calls to repair Asus and Apple PCs on average, said David Milman, Rescuecom’s CEO. The companies offered PCs with high-quality components and excellent support, reducing the need for consumers to service PCs through third-party support companies.

The ratings were based on 11,560 support calls fielded by Rescuecom during the second quarter and adjusted to take into account the market share of each PC maker. Lenovo, Toshiba and Hewlett-Packard held the third, fourth and fifth spot respectively in the PC reliability survey.

The study was released on the same day the University of Michigan and other organizations issued the American Consumer Satisfaction Index, which measures user satisfaction with products including cars and PCs. Apple topped the survey with a score of 85, followed by Dell at 75, and a three-way tie between Hewlett-Packard, HP’s Compaq brand, and Acer/Gateway, which scored 74.

Consumers want PCs that require minimal repairs and good support, so the calls provide a good snapshot of PC reliability, Milman said. Companies that provide high-quality components tend to rate higher, while bad components and bad support may force PC owners to call third-party repair companies.

“We review … a combination of how reliable the components are and how good the support is from the manufacturer,” Milman said. Multiple PC components, including motherboards, memory and video cards were factored into the survey. The quality of software bundled by PC makers, including security and office suites, was also part of the survey.

“If a manufacturer provides quality software that is less trialware, especially in the area of [security]… it is certainly something that makes their computer less necessary to be supported,” Milman said. Many PC makers are also bundling one-touch data restore options in PCs, which reduces the need for customer support.

Asus is relatively new to the study and is reaping the benefit of the recent craze for products like netbooks in the U.S., Milman said. Many users are buying Eee PC netbooks, but the company’s PC reliability ratings might change as components start to break down, Milman said.

“Their quality has held up from the last study, but it will be interesting in two years once the machines age a little bit,” he said. Increased support calls for Asus products may help better evaluate the company’s support, Milman said.

Among the top five PC makers in the U.S., Apple has offered a steady stream of PCs with quality components and support services, Milman said.

“With the introduction of their Apple Genius [Bar] in retail stores, they are offering support that many other manufacturers aren’t offering,” Milman said. Apple’s margins on the Mac desktop and laptop PCs are much larger compared to competitors, so Apple can afford to offer free support, Milman said. Many Rescuecom technicians are certified by Apple to repair Mac computers, Milman said.

Rescuecom received more support calls for Dell and HP PCs, which were the top two PC vendors in the U.S. during the second quarter, according to IDC. Dell rated seventh in Rescuecom’s study, with 22.1 percent of the repair calls. Though HP and Dell held close market shares in PC shipments, Rescuecom received 18 percent more support calls on Dell PCs than HP.

Rescuecom established a baseline to rate reliability by balancing the number of support calls with the market share of PC vendors, Milman said. The study was not commissioned by PC makers, and the company has no support ties with PC makers.

Verizon Wireless is again offering a second BlackBerry with each one purchased, but this time the deal includes any other device — of equal or lesser value — that Verizon sells.

That means new subscribers, or those signing new two-year contracts, can get a free netbook with a BlackBerry Tour smartphone. The Tour costs US$199.99 after Verizon’s rebate, and the least-expensive netbook Verizon sells is the HP Mini 1151 NR, also priced at $199.99. Those customers could also get any USB, PC Card or ExpressCard modem the carrier offers.

The offer also covers the Intelligent Mobile Hotspot, a $199.99 battery-powered 3G modem that includes a Wi-Fi access point that can be used with any five Wi-Fi devices. To get any of these devices free with the BlackBerry, the customer would have to sign up for a two-year contract for both devices. Monthly data plans start at $39.99 with a 250MB cap and $59.99 with a 5GB cap.

Research In Motion and Verizon both have been working hard to grab attention and sales from the still-popular Apple iPhone, which in the U.S. is offered only on Verizon rival AT&T’s network. A BlackBerry buy-one-get-one offer that Verizon ran earlier this year was widely credited with helping the BlackBerry Curve beat the iPhone in unit sales in the first quarter. The BlackBerry Storm, RIM’s first touch-screen product, also debuted to hot sales in that quarter.

With the latest promotion, Verizon wanted to make sure its customers were able to get the second device they needed, instead of limiting them to getting another BlackBerry. Verizon sells all other BlackBerry models for less than the Tour, ranging from the Storm at $99.99 to the BlackBerry 8703e for $29.99, each with two-year contracts.

The Tour, which debuted last month, can work on both the EV-DO (Evolution-Data Optimized) network technology used by Verizon and the GSM/HSPA (Global System for Mobile Communications/High-Speed Packet Access) system used by most carriers outside the U.S. It is available in models with or without a 3.2-megapixel camera, meeting the security requirements of some businesses and government agencies. Both models cost $199.99 at Verizon.

China said Thursday it will not force PC makers to bundle an Internet filtering program with computers sold in the country, backing down from a plan that stirred global controversy.

China will “definitely not” require the program, called Green Dam, to be packaged with all consumer PCs, said Li Yizhong, China’s Minister of Industry and Information Technology, according to a transcript of his statements on a government Web portal.

China originally ordered all foreign and domestic PC vendors to pre-install Green Dam on new machines or to include the software on a CD-ROM. That mandate, issued in May, was indefinitely postponed just hours before it was slated to take effect last month. At the time, the Chinese government said it delayed the plan only to give PC makers more time to comply, but it did not set a new date for enforcement.

Thursday’s statements were the first clear sign that China would not enforce the plan, which drew strong protest from Western PC makers and industry organizations. China has insisted that the Web filter was meant to protect children from pornography, but the program was also found to block Web sites that mentioned sensitive political topics such as Falun Gong, a spiritual movement banned in China as a cult.

Concerns about the program ranged from free speech and user privacy to PC security and intellectual property violations. A California-based software maker last month said it was preparing legal action over Green Dam for its use of programming code stolen from the company.

Li said use of the filter was meant to be optional and that the plan was misunderstood because it was not explained clearly. The software can be disabled or uninstalled.

PC makers including Lenovo, Acer and Asustek Computer have gone ahead with plans to distribute the program.

China’s government will go ahead with installation of Green Dam on computers in public schools, Internet cafes and other public places, Li said. It is also working to address flaws in the program and would not rule out introducing a better filter, he said.

Moving the entire Mac lineup to shiny, glossy displays has been one of Apple’s many controversial decisions in recent times. When the company initially launched the unibody MacBooks and 15-inch MacBook Pros in October 2008, it made a glossy display the only option on the latter, raising the ire of a large minority of very vocal customers. The introduction of the glossy 24-inch LED Cinema Display during the same event, which replaced its matte-screened 23-inch predecessor, didn’t do anything to appease said users either.

Perhaps taking a lesson from the outcry, Apple retained the option to custom order the 17-inch MacBook Pro, which was introduced in January of this year, with an antiglare display for an additional charge of $50. Furthering that trend, Apple has now made the $50 antiglare display an optional installation for the 15-inch MacBook Pro as well. As with its heftier sibling, you’ll only be able to take advantage of this option if you order your notebook through the Apple Online Store.

Fans of Apple’s 13-inch notebooks–the MacBook, MacBook Air, and 13-inch MacBook Pro–still only have the glossy display as the available option. If you really want an antiglare display on your existing Apple notebook though, TechRestore has just the right service for you. Now that Apple seems to have decided that the matte look isn’t so bad after all, we can only hope that the company will consider bestowing it upon the whole notebook family–and maybe even the iMac and LED Cinema Display as well. Or is that asking for too much?

The Chinese government’s science institution wants to sell its 29 percent share in Lenovo’s parent company, potentially putting more control of the company in the hands of private investors.

The Chinese Academy of Sciences, which is a state-run institution that conducts national research projects, is asking 2.76 billion yuan (US$404 million) for the piece of its stake in Legend Holdings, Lenovo’s parent company, a spokesman for the academy’s investment arm said Tuesday. The sale would bring the academy’s stake in Legend down to 36 percent from its current 65 percent, he said.

The academy wants a buyer with experience in areas like capital management and marketing, which are not covered by the state-run academy’s technical expertise, the spokesman said.

The buyer must agree not to resell its stake, alter Legend’s strategy or propose changes to the company’s executive base for five years, the academy said in a statement. The company must have registered assets of at least 4 billion yuan and cannot be backed by foreign investors.

The academy does not currently plan to reduce its stake further, the spokesman said. Lenovo declined to comment.

Lenovo began restructuring this year to build its focus on China and other emerging markets after its enterprise sales in Western countries took a severe blow from the economic recession. The company, the world’s fourth-largest PC maker, announced last week a quarterly net loss for the three months through June 30. The figure was an improvement from Lenovo’s larger net loss in the previous quarter, but still stood far below the company’s net profit of $110 million a year earlier.
