Notebook batteries


The use of rechargeable Toshiba PA3383U-1BRS laptop battery is the relative advantage of one of the desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is a nickel-cadmium battery (NiCd), but the batteries have a "memory effect", each charge to be discharged, very easy to use, and soon they were nickel-metal hydride battery (NiMH) replaced, NiMH not "memory effect", and the weight per unit to 10 percent more electricity. At present, the most commonly used battery is lithium-ion battery (Li-Ion), it has no "memory effect" compared with NiMH, receive more weight per unit of electricity, the price twice as high than the NiMH. In the same weight, the use of the three longer than the battery is 1:1.2:1.9. There is also a battery called polymers, very high capacity, small size, the majority used in Apple Computer.
At present, the use of notebook computer batteries in three main categories: 1. Ni-Cr Toshiba A60 battery, 2. Ni-MH Acer Aspire 3600 battery , 3. Lithium batteries; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, lithium LI.
Purchase or replace the laptop battery when, for many users, the "batteries" may be unfamiliar. First statement, batteries and battery are the two concepts. A battery is a number slightly larger than the thumb, cylindrical, about 7-8 cm, voltage of 3.6v small units, it is called professional called 18650, Sanyo and Samsung is the largest producer. Batteries , like a small battery, the combination of tandem, that is, we can see the battery. Then talk about how to judge the battery is the core of a few:
One way: unplug the battery number of contacts to see him, there are several that several of the core. But this is the "Minister" approach. We take a look at "Cao Chong" is how, "said the elephant" of: take a look at the number of your battery v nominal, such as 14.4v, and then divided by 3.6 to be 4, it proved to be in series with the battery 4. And then take a look at the capacity of the battery block, for example, 4400mAh, then proved to be the two groups mentioned above batteries in series, because the small battery capacity of 2000-2200mAh, or even more, and together the two groups can be reached 4400mAh. According to the two judgments, then the battery is 4 × 2 = 8 cores.
Composition notebook Toshiba pa3383u-1bas battery
Notebook batteries by the case, circuit board components and batteries are lithium-ion battery. It is generally talking about batteries means the battery is the number of batteries, mAh refers to the capacity of notebook batteries.
The main circuit board by the protection circuit (or the second protection circuit), as well as the capacity of the two parts of the circuit composed of the instructions on the laptop battery charge and discharge management and safety.
Notebook battery standby time of major decisions by the mAh value. Under normal circumstances, a few more batteries, mAh value the greater the longer standby time. Toshiba pa3331u-1brs battery life mainly by the number of charge-discharge measurement, the quality of the products are generally qualified for 500-600 times. Therefore, the effective use of laptop batteries for 2 years, will expire aging batteries, standby time the impact of the drastic drop in the mobility of notebook computers.

five major notebook troubles

To express appreciation of the vast numbers of users has been the support of the World network, we focused on the use of notebook users encountered some trouble, go to the relevant funding body of the laptop experts, selected by everyone experiencing the five issues, to the vast number of users friends supporting ideas.
1, friends, Mr. Wang is an electrical engineer job, use of the notebook is the Haier T61, as reflected in his notebook battery life issue is a comparatively short time.
Expert advice: the same HP Pavilion ZD7000 batteries are consumable items, and many manufacturers in the promotional campaign that notebook battery in case power is still able to support more than four hours to run, but in fact in power, the battery life and user operation There are a lot of the relationship between the procedures, if only to see movies, running a number of relatively simple procedures, life would be a relatively long time point. And if it is to play games or use some of the design of large-scale software, the general can only maintain the 1 - 2 hours.
2, and some notebook users reflect the noise, always use the time to hear the voices of a number of hula hula.
Expert advice: have a notebook noise usually comes from fans. The size of the fan noise is a manifestation of CPU power. Dell XPS M1210 Battery needed for the operation of CPU heat dissipation. If it is not the cause of the accident, the general noise makers in the design will take into account the time. If it is the impact of the use of after-sales service can help find a solution, or feedback to the manufacturers, should be a good solution.
3, Wu friends, at school and university students. Reflected in the quarters to use the computer, always feeling hot feeling like notebook, notebooks have been asked is this the case of heat, will have damage to the notebook.
Expert advice: the issue of laptop cooling fans has been a vast number of notebook issues of concern, although the manufacturers have been addressing this problem, but long-lasting heat is always difficult to eliminate, so it certainly has been hot on the notebook ThinkPad T60 Series Battery, the other hardware damage, if it is a very good hostel there is no thermal environment, it is recommended in hot weather should not Win
Line the procedure is too large, you can buy in the shops a number of notebook accessories notebook cooling base, the general base are embedded heat 1 - 3 small fans, those fans on the notebook's battery, as well as better machine than the heat to help, so that the relative protection in good books, but also to maximize the use does not affect users.
4, Mr. Zhang users engaged in management occupations, the use of the Compaq Presario v3000 Series Battery is a Lenovo C466, in the use of the boot process more slowly, so the notebook has been suspected to be not a problem.
Expert advice: slow boot laptop, the main boot may be more start-up items, you can type in the system between the start run command to start some unnecessary to ban it. Or some system software, such as optimization of the master, the start of clean-up look. Many notebooks now are used in Vista system, the system in a notebook because of their more intelligent behavior, the corresponding detection of more and more, it is relatively slow boot normal, with optimization of the master, to some unnecessary after the start of the prohibition,Sony Vgp-bps4 will start to upgrade the speed of a corresponding.
5, In addition, some users reflect the Acer Aspire 3000 BAttery with the Logitech keyboard is not compatible with some problems. This is I believe we are also concerned about the following, we will look at the recommendations of experts:
Expert advice: You can not use is normal, you use the USB interface keyboard on the much more convenient, but you are using a switch interface, use the notebook keyboard interface is used can not be transferred, this movement is to interface the question. Such circumstances there is no other method can only say that to another level is the change in interface or USB keyboard?? If it is not compatible, you can contact Logitech telephone companies to allow experts to answer the case.

Notebook Battery Tip

The biggest advantage of notebooks is its mobility, can not be considered space, the use of anytime, anywhere, that is of concern to it like it's the most important reason that the notebook has become the embodiment of environmental protection and energy saving is an important factor in the notebook performance. Typically, the majority of notebook computers to maintain the use of time of about two hours, if we consider the purchase of the battery and do not want to do another extension, no doubt, it is necessary to proceed from the perspective of energy saving power, today we have to share about the power of notebook a few tips.

Typically, the Friends of the Ibm Thinkpad t30 Battery most sensitive point is direct - life. Life of notebook computing, there is a formula, namely: time = Battery Electric Power / computer total power consumption. Typically, the total power consumption can be obtained directly from the parameter table, and the battery will need to re-calculation of reactive power. Calculation of Electric Power batteries also need a formula, namely: Battery Electric Power = Battery capacity × DC voltage. These two parameters can remove the battery, see the back of the battery, as shown in Figure 2.

This Internet of the Samsung NC10 battery battery capacity of 5200 mAH (5.2 AH), DC voltage of 11.1 V, so for Electric Power 5.2 AH × 11.1 V = 57.72 WH. (Note: mAH: Reading for "milliamperes" generally as the capacity of the Ibm Thinkpad x24 Battery unit. At 1 mA current output, the use of 1 hour of battery capacity spent one milliamperes when called; WH: Reading for the "Wh "is the unit of reactive power. 1 W of electrical power consumption of 1 hour is 1 watt when.) Thus, to calculate the battery life, assuming that: the total power consumption for the notebook battery 10W (watts), Electric Power for 57.7WH, then it's time = 57.7WH ÷ 10W ≈ 5.8H, that is 5 hours 80 minutes.

For details of the performance of Ibm Thinkpad x61 Battery, the need to understand several aspects of the Friends. First of all, by the formula we can draw the same configuration (near) the machinery, the greater the electrical reactive value of the longer battery life. Therefore, if the mobility of the Friends of the premise, buy books at a similar configuration should be to focus on the total battery Electric Power. Second, is the "batteries" of the discussion, namely Cell. Friends of the view that the majority of the 6 Cell Battery 4 Cell use than a long time, the visual impression is correct, but it is the same for the 6 Cell battery, high capacity, the use of time may not be president of some, because only two batteries the same output voltage, the larger the battery capacity, battery life was longer.

On the books "batteries", explain in depth here. Books from the battery-powered batteries, the market can see the single-core, 3 core, 4 core and 6-cell Sony VGP-BPS2 Battery, of course, there are more, such as: 8 Core / 9-cell battery can be maintained group of about eight hours electricity, but the mainstream or 3 core, 4 core and 6-cell battery.

Multi-core battery composition, mainly by way of series-parallel connection, series for: the same power consumption, voltage sum; parallel way: the same voltage, power consumption add up. Details refer to Figure 3. Samsung notebook products as an example: 3 Cell battery, ND10 used only; 4 Cell battery pack to serial-based structure, the use of previous generation products, such as X11, R20, etc.; 6 Cell battery pack, the basic 2 and 3 Series structure, the main products were active.

Books day-to-day skills in the use of power

Day-to-day use, a number of energy saving techniques adopted, the books can also extend the life for us, especially for the large number of power "monitor", the effect is very remarkable. First of all, the laptop LCD display is a large power consumption and lower the screen brightness can be very effective in reducing the power consumption and extend battery life, the environment is dark do not need higher brightness, we can reduce it appropriate. At the keyboard, the majority of models to adjust the screen brightness of a combination of keys for the "Fn + F6/F7", the specific operating instructions can be found randomly.

Can effectively reduce the screen brightness to reduce power consumption books

Second, abolish the "Screen Saver", you can increase Compaq PRESARIO V4000 Battery life. Stand-in and remain seated when the abolition of the Friends of the best screensavers, or power switch set to standby mode, this action in accordance with different operating systems, set up a different way, we will detail the next section. The elimination of the specific operation for the Safety Net: Office space on the desktop using the right, select "Properties" and select "Screen Saver", a direct choice "no" can be identified.

3. In the "sleep" mode, users can enable it, will leave his seat when in the stand, the easy response.

In the XP system, the power settings to complete these three operations, the energy of the book will be of great help to me.

Vista notebook system power skills

Vista for the new system, some people have done a test and found that the effect of open and open Aero sidebar, after more than an hour of electricity will be reduced to about 85 percent, and the closure of these two effects, the same time reduced the power only about 90%. The longer the gap the greater the Aero and the sidebar closed up 70 percent to the province's power. Through this point can be seen running, "fancy," the process of power really. Closer to home, Vista system with the XP system, better bring their own set of power control scheme, it was the ideal setting, the effect will be more ideal life. Specific operations as follows:

1. Click the system tray power icon will pop up as shown in Figure 14, floating window, here are three different power scheme. The default setting is "balanced", when the computer is idle long-term, it will automatically switch to power-saving mode, which is a more energy smart program. "High performance" mode, the system the fastest, of course, is the largest power; "energy-saving procedures," you can make to minimize power consumption, but this scheme will be reduced to some extent, the performance of the system, after all, difficult choices Sony PCGA-BP71 Battery.

2. Through the "Start" - "Control Panel" - "to change the power settings" on the battery can also be a more comprehensive set.

3. Interface tab in the first three the same interface, you can set up three models, namely, sleep, sleep and off. Three models, the more recommended "sleep" mode, and an additional password to wake up, it will not remain seated when the excessive consumption of electricity, but also can be password-protected interface.

4. In the "Select the display time to close", "change the computer's sleep time" and "mediation display brightness" option card, users can set up and remain seated on the machine to respond to the specific settings can be combined to operate from the environment, it is worth mention is: where should the screen brightness set to minimum value.

5. In the above-mentioned three tab, users can use the "Change advanced power settings" option, to conduct a more comprehensive energy-saving setting, this level tab is more than the level of coverage, such as: show appearance response time, screen brightness and so on are involved in, the user can also find more user-friendly.

Third, the adoption of some commonly used ports or hardware to "ban" can also be saved in mobile use considerable power. Similar to PC card, such as pulling, USB, IEEE1394 interface,Compaq PRESARIO R4000 SERIES Battery, such as any device, or disable the CD-ROM, wireless networks and Bluetooth devices can save electricity. Disable hardware devices, such as the common drive, as follows: Right-click "My Computer", select "Properties", then select "Device Manager" in the menu to find the hardware option, and in the pop-up menu, select " Disable "or" Uninstall "option. As for the wireless network and disable Bluetooth devices, it is through the shortcut keys to complete the specific operation of the models please refer to the relevant instruction manual.

Fourth, timely monitoring of system resources, books to adjust working conditions to reduce the process of reading time, this energy can also be based. Through the combination of keys "Shift + Alt + Ctrl", out of the process menu, and then set up to process resources, hp Omnibook xe4 Series Battery or run as a "super rabbit" and the system cleaner software to repair to collate modify system operation, not only energy-saving at the same time most system can save space, can be described as dual.

Finally, the right of the battery discharge, the battery characteristics can also be enhanced to achieve the ideal power supply. Most new laptops have a standard lithium-ion batteries, such batteries do not have too much on a full charge-discharge operation, but they still have a slight memory effect, the use of notebook computers in a year or so has become particularly apparent when , especially those in power every day, then use the users. Discharge operation ideal, should be every 2 months to conduct a complete battery discharge, and remove the cloth, and placed ventilation. This will increase battery life and maintain performance.

XP system notebook power tips

Running in the books, monitors, hard drives in a working state at the same time, sometimes the user for a long time because of various reasons not to do it, if they continue to work, this will result in waste of energy. Windows XP provides users with an ideal power management program, the user can according to their own set of the actual situation, it will not only save energy, but also more effective maintenance of computers, to extend its life. Power management settings for the specific steps:

1. Click "Start" button, select "Control Panel" menu, double-click "Power Options" icon, you can open the "Power Options Properties" dialog box. In the "Power Schemes" tab, in the "Power Schemes" drop-down list box provides users with six different options, based on the actual needs of the user can choose their own program. In the "power scheme settings" option in the region, we can turn off monitor, hard disk, such as the waiting time for different settings. If it is found that the program does not provide for themselves, users can customize their own power scheme, set up in this waiting time, click the "Save As" button.

2. In the "Advanced" tab, users can choose to use energy-saving settings, such as when you select hp Omnibook xe4500 Battery "always show icon on the taskbar" check box and apply after the desktop appeared on the task bar kind of a small plug icon, but also the power button on the set of options.

Innovative qualitative mainstream solid-state notebook hard drive will be configured

Read because of its speed and durability size characteristics of light, SSD gradually attracted widespread attention. It uses ultra-portable notebook computers name started (such as Apple's MacBook Air and ASUS Eee PC), HP PAVILION ZD8000 Battery has been classified as ultra-high price-matching products, have always been regarded as a symbol of fashion. However, with rapid updates IT hardware, SSD now has begun to fall into the hands of appeared in more and more among the mainstream notebooks. The era of solid-state hard drives come quietly. Both large and small notebook computers, or high-end gaming PC, this matching can be high-capacity, high-speed hard disk Chuan.
Solid-state hard drive
Ultra-portable products: on the present situation, solid-state hard drives are widely used in ultra-portable products. Lenovo launched the IdeaPad S10, with a 4GB SSD. 10-inch ASUS Eee PC 1000, with a 40GB SSD, the price is less than 700 U.S. dollars.
Conventional notebook: HP EliteBook 2530p recently introduced to matching Intel 80GB SSD, which launched this month, Dell E4200 can also be matching the 128GB SSD. Even in the mainstream of HP 530 Battery products are the emergence of SSD, such as 15-inch XPS M1530 has provided solid-state hard drive, and relatively cheaper prices.
The field of high-end games: SSD will be regarded as the beginning of the ultimate high-performance storage devices. Intel demonstrated a previous 80GB X25M SSD, its performance beat 7200-rpm, 500GB Seagate Barracuda hard drive record. SSD which reached 44,000 IOPS, and Seagate products is less than 550 IOPS. If this is the practical application of performance can be reflected, then the professional game for the PC manufacturer is very tempting.
In addition, along with flash memory prices continue to decline, Apple M8433GA will be the cost down from the ultra-portable products, at no additional cost under the premise of each year using the average notebook SSD storage capacity will be upgraded. At present, the most critical is the PC manufacturers and consumer acceptance of the SSD to be raised there, but can be predicted that the future solid-state hard disk will become the mainstream notebook computer configuration.

Japanese automotive lithium batteries


For consultants in the new energy automotive industry researcher Sheng-mao that the current lithium-ion battery electric bicycle has been gradually, to expand in areas such as electric vehicles. With the global demand for lithium battery applications and expanding year by year. Li-ion Dell latitude d630 battery is currently the global automotive industry is entering the phase of rapid development, the battery manufacturers to engaged in a fierce competition for market competition.
According to Deutsche Bank research shows that most are willing to vehicle 10 with the following car companies to develop lithium batteries: 1) JohnsonControls-Saft (the United States and France, Johnson Controls and Saft joint venture); 2) A123 Systems, Inc. (from the Massachusetts Institute of Technology , General Electric and other investors to set up, the company co-operation with the mainland groups); 3) LG Chemical (The company has subsidiaries in the United States CompactPower); 4) EnerDel (Ener1 and Delphi joint venture); 5) AESC (Nissan and NEC joint venture); 6) PEVE (Toyota and Panasonic joint venture); 7) GS Yuasa; 8) Hitachi; 9) Sanyo Electric; 10) Samsung.
Alternative energy sources and authoritative editorial GreenCarCongress site MichaelMillikin forecast future vehicle manufacturers of lithium batteries, "three" is: 1) PEVE, 2) AESC, 3) LG Chemical. Most of these suppliers and companies signed at least two vehicles, and several of the world's major car companies in general to choose at least two suppliers of lithium batteries.
For consultants in the new energy automotive industry researcher Sheng Mao pointed out that research can be found above, at present, Japan's lithium Dell laptop battery suppliers in the global marketplace is indeed a large advantage. However, in recent years in China Li-ion battery technology in the car also has to catch up, BYD is the best in the industry, and recently its just with the German Volkswagen lithium batteries for electric vehicles to reach the supply agreement.
