IDC PC market 10 Forecast: Touch PC devices difficult to National

An American company to market research IDC recently released the top ten worldwide PC 2010 Market Forecast. IDC estimates that the economic crisis of 2009, access to global markets to all other shipments of personal computers at low cost has risen sharply. A1061 A1078 A1079 The continuation of this trend, with the PC industry in 2010 to collect, laptops, thin and light play an important role. In addition, a computer has also grown.

IDC said: “We expect business users and consumers more inclined to try a new PC. Lower prices will exacerbate this trend. Hardware manufacturers and software developers should take this opportunity to highlight the differences in re-write interface to accommodate the entire new PC category. ”

The following is the 2010 PC market, IDC’s Top 10 predictions:

1, high-end ultra-portable purposes (like the MacBook Air, Adamo) in the PC market as a whole, the proportion is less than 5%. This is contrary to the general surprise, but IDC believes that consumers are thin and light notebooks with concern that although rising, but for consumers, these products are obviously low cost. It is difficult to establish substantial growth.  A1148 A1175 A1185

2 shipments of Internet growth is slowing sharply. That homogenization of serious, thin and light notebooks is more extensive attention. Therefore, the Internet transmission of this product will enter a period “platform.” Below the overall increase in the laptop category.

3 prices Desktops fall more slowly. Business and consumer market, steady demand. Shipments of PC Desktop constant. Therefore, market development will be difficult to significantly affect the market for desktop PCs.

4, built in shipments of notebook WiMAX. With the rapid development of network, a practical point of view to enable the rate of, 3G is still stronger than mobile WiMAX laptop. But it also laid the groundwork for the popularity of WiMAX. A1189 M8403 A1280

5, a computer share doubled. A machine may be called in 2009 the highest growth in emerging products. Major PC makers are increasingly interested in the product increased. 2010, these products will be significantly increased, or will this year, the global market for desktop PC to earn a 10% share.

6 laptop (like notepad Culv) will be a breakthrough in the share of global transfer of 50%. Factor in the popular laptop has never changed. There is a growing popular portable notebook. ThinkPad R40 battery ThinkPad X60 battery

7, the newly acquired business desktop client, there are about 10% use the format of virtual machine. The economic recovery will allow more companies to try a new type of model calculation; the use of desktop virtualization client will be significantly increased.

8, computer touch screen will not be much improvement. If you do not provide enough software to touch attractive, consumers will not have much interest in the PC to the touch. In turn, there is not enough bases of users, application developers are not willing to invest a large number of managers to develop software touch. VGP-BPS2A VGP-BPS2C VGP-BPS2B

9, Apple iPad will not stimulate the sales of Windows Tablet PC. While in 2010 the first year or so-called tablet PCs. Hewlett-Packard, Lenovo and a number of PC makers have also launched their own tablet computer products. However, the actual shipments will not be too high.

10, DVD will remain the main PC CD-ROM category. Blu-ray equipment, both in price and in the position of the PC industry, it is difficult to compete with the DVD. Therefore, the 2010 DVD is still the general public. VGP-BPS8 VGP-BPS8A

Laptop battery using secret tips

Computer battery is the basis for mobile applications, but also a kind of consumables. Many users claim that their VGP-BPS9 VGP-BPL8 batteries for six months on the charge could not afford electricity, but actually, if you pay attention to the daily use of maintenance battery, maintenance can significantly extend their useful life.

First, the establishment of appropriate solution for energy management.

1. The establishment of the appropriate solution for energy management not only to meet the needs of daily use, but also extend battery life. New program to power management, solutions management first plant to be named, to facilitate future management and switching. And then need to set the processor speed and brightness of the LCD, so the extra system resources, not much lower frequency of the processor can be used to reduce power consumption and improve battery life. Powered by battery, it can appropriately reduce the brightness of the LCD to save power. Then go with the hardware (disk drives, LCD screens, etc.) and the system hang time. Here there is no fixed model set-up time should be based on their actual needs.

To support the effective management of power solutions for battery management, it should be enough power to set the alarm time. Because the characteristics of lithium-ion batteries to extend battery life, the remaining capacity may be less than 5%, or go a long battery life will be significantly reduced. It is preferable to set the battery discharge to 6% to 7% of the alarm, the alarm can be set to the text, it will not affect others. Alarm after the system response can be configured in standby or hibernation, the system shutdown after the timely replacement of batteries or recharge the battery, to avoid excessive discharge and shorten battery life.

2, set the threshold of perception

With the increasing number of charge cycles, battery capacity would be gradually reduced until the end of life, giving reasonable cost thresholds may actually prolong the life of the battery. Many laptop manufacturers to develop third party software power management function is provided for adjusting the threshold of support. The so-called threshold value is a charge to allow battery charging power range, usually a percentage of unit power from the battery.

Threshold settings of care in general there are three options: Always load, the load is automatically set thresholds and custom. Has always been as long as the battery charge is below the battery Jiugei is suitable for users who often use battery-powered, if you do not use batteries do not choose, otherwise it will shorten the life of battery. Load threshold is set automatically by the software power management, according to the actual capacity of the battery charge a reasonable calculation of the threshold level is not high for laptops with a friend. Customized by the user to define load levels, suitable for notebook users who are more familiar. Function using the author’s experience, the battery “health” of the case, the load threshold is set at 30% ~ 80% is appropriate (that is, less than 30 % of charge remaining capacity, remaining capacity is greater than 80% free) in the case of aging and the battery is charging threshold set at 40% ~ 70% is appropriate.

3, the calibration of the battery

Some software power management feature provides a calibration of the battery, calibrate the battery on a regular basis can make the chip Battery Management registered in battery capacity closer to actual capacity achieve the goal of extending the battery life. Before the battery in the calibration must be closed other applications and documents, and an AC power adapter externally. And then open the calibration function of the battery, the software will do the depth of battery discharge and then full power (some laptop batteries included in the calibration procedures of the BIOS, the need for setting implement the BIOS).

Without calibration function of the battery for laptops, we can manually correct the battery. In the case of full power, first close all applications, disable the screen saver and hibernation system, function monitoring. Then close the LCD screen and optical drive, disable the wireless adapter, then unplug the power adapter. Do nothing until the 367759-001 F2024A laptop automatically closed. And then re-external AC adapter until the battery is fully charged the battery after completion of the operation manual calibration.

The already significant degradation of the battery must also take corrective action if the battery capacity decreased after adjustment, we can not continue to be calibrated the battery. A significant deterioration of the battery frequent calibration will significantly shorten the battery life of the battery or even a direct consequence of scrap battery. For normal use the batteries, a battery can be adjusted up to three months, otherwise, would damage the battery.

4, the battery not use should be maintenance

Most of the time many users are using the AC power supply to their books, very few used batteries. Some users may think that does not use batteries, the batteries’ longevity. In fact, battery production will begin after the aging, the battery capacity remaining is too high and long term does not discharge the battery life will be shortened. Which are not commonly used in batteries, can charge its battery to 30% ~ 60%, then the battery with waterproof waxed paper wrapped and placed in direct sunlight can be ventilated and cool. And every six months is also required for battery charging and discharging time, which can protect A1185 A1045 battery life.

Learn the details about laptop battery

Use rechargeable batteries for laptops, one of the advantages of the desktop, it can greatly facilitate a variety of environments using laptops. Introduced the first VGP-BPS2 VGP-BPS2A battery is nickel cadmium batteries (NiCd) battery but has a “memory effect”, each charge is required before the evacuation, very easy to use, and soon found himself nickel-metal hydride battery (NiMH ) replaced, NiMH not only failed to “memory effect”, but can do more per unit weight of 10% of electricity. The battery most commonly used is lithium-ion battery (Li-Ion), it is also ineffective “memory, compared to NiMH per unit of weight gain more power, the price two times higher than the NiMH . In the same weight, these three kinds battery is 1:1.2:1.9 ratios.

Notebook batteries currently used in three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium, they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium-ion battery LI.

The purchase or replace the battery when the laptop for many users, “battery” may be unfamiliar. At the outset, batteries and batteries are two concepts. A battery is composed of several slightly bigger than your thumb, cylindrical, up to about 7.8 cm, the voltage is 3.6V small units, a professional name that is called 18650, Sanyo and Samsung is the first manufacturer in China. Batteries as a small GK479 U4873 battery, thanks to the combination series, that is, we see that the battery a. Then talk about how to judge the battery are several nuclei:

One way: Disconnect the battery for the number of contacts to see, there are a few tens of cores. But it is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such that 14.4v, then divided by 3.6 to 4, then turned out to be four batteries together in series. And then take a look at the capacity of the battery pack, for example 4400mAh, then prove that the two aforementioned sets of batteries in series, because the battery capacity is low for 2000 — 2200mAh or more, and together the two groups can be achieved must be 4400mAh. In both cases, the battery is 4 × 2 = 8 cores.

The composition of laptop battery

Notebook battery from the shells, printed circuit boards and batteries belonging lithium ion battery. People talk about batteries in general refers to the number of batteries in the battery mAh refers to the ability of the laptop battery.

Mainly by the protection circuit (or the secondary circuit protection), and the capacity of the circuits in two parts, the laptop PP2182D PP2182L battery charge and discharge management and safety.

Time Laptop Battery standby mainly by the value mAh decide. Under normal circumstances, a little more battery, the mAh value is greater than longest standby time. Battery life for notebook mainly by the charge and discharge times to measure the quality of the products is generally eligible to 500-600 times. Therefore, efficient use of laptop batteries within two years expired the battery is aging, standby affect the strong decrease of the mobility of laptops.

Abstract:

Most laptops today use lithium batteries, in which over 13 inch notebooks, especially over high capacity 6-cell battery, while the 13-pad of thumb to ensure portability, many products have chosen the 3-pin thin around the battery. To get the most A1185 A1045 battery life of portable, many manufacturers have started to develop fuel cells, I believe that sooner or later we can see the production version of the fuel cell, then you really can-office Portable weather.

Environment-friendly vehicles lithium-ion battery engineers began to focus on cost

Special Act - as well as hybrid and electric vehicles are becoming increasingly close to the production of lithium-safety concerns ion batteries have started to move from economic practice.

In last Tuesday to the plug-in cars in a roundtable discussion at the meeting, several speakers said that once such an advanced Laptop battery to achieve mass production, cost reduction can be significant.

Members of the Security advanced batteries has not expressed concern over the battery in the past, electronic consumer products, there had been overheating and fire.

Johnson Controls-Saft Advanced Battery Systems for Hybrid Battery System of Public Affairs and External Relations director Michael Andrew, said that the company’s goal is to lithium-ion IBM ThinkPad T41 battery packs cost reduction of 50%.

He said, JCI-Saft batteries into consideration not only cost but also consider a battery mode of production. He said that battery manufacturers can learn how other industries can be more effective production of lithium-experience ion battery.

Andrew said: “We now have an opportunity to review the production of these batteries.” We believe we can learn from other industries used in process technology, to rapidly reduce costs. ;

Par with gasoline

He said the objective of JCI is to produce for the use of batteries or hybrid electric vehicles, allowing consumers to spend and spend three years of the same gasoline engine.

Nissan North America manufacturing engineering and manufacturing engineering of the vehicle, said Mark Swenson, vice president of Nissan in 2012 to reduce the cost of sheet map of electric car involves the manufacture of batteries in the factory manufacture of vehicles will be assembled into Dell Inspiron 6400 battery packs.

Swenson said: “We intend to plant every day without interruption of production to production facilities enable us to maximize the investment. He said, Leaf North America, but Nissan plans to sell several models of electric vehicles.

A123 Systems Inc. Vice President, Business Development Ric Fulop said he believes the industry matures the cost of the hp F4812A battery can be reduced by 9% per year. To perform a battery of higher power can save some costs, while also optimizing production processes and use high quality materials to reduce other costs.

More power

Dow Chemical Co. ’s Global Business Development Director of the Department of Ravi Ramanathan said that the cost of energy the toshiba PA3399U-1BRS battery can also make a stronger battery and more efficient, and quality control during production to be cut.

Automakers do not speak about the battery and hybrid electric vehicles used in packaging costs. However, according to some, to be Chevrolet Volt lithium-ion batteries used in estimating costs of approximately $ 8,000.

Ramanathan said, “the high cost of the apple A1185 battery, you must descend.; He said that the initial cost may be high, as automakers and car batteries for most designed to ensure that consumers do not appear on the technical loss of goodwill of mechanical failure.
