In the plan to buy non-original notebook battery, at first we need to have some knowledge about the notebook battery market to know what kind of battery be considered as a good quality non-original laptop battery? How the non-original laptop battery is produced, and generally only have to sell, what’s the general price would it be? Secondly, we need to know how to judge a quality of non-original laptop battery is good or bad, from which parameters or criteria to judge? I have collected online on “how to buy non-original laptop battery” of knowledge, compiled this article, We hope that they can help!

Understanding of the domestic market, What are the categories about laptop battery :

1. Original Laptop Battery: (usually a notebook manufacturers signed an agreement with the laptop battery manufacturer in cooperation and not to sell, only available to the laptop manufacturers only belong to regions, that is, within our common store sales, higher selling prices)
2. Fake original laptop battery: (This laptop batteries are mostly sold on  eBay, the use of original laptop batteries due to the high price of the general consumer with cheap psychology, with some mechanical and electrical core, or with the demolition of the old  circuit board assembly into the final change into a new shell, original labels deceive consumers. NOTE: This so-called original equipment batteries and not gone through rigorous safety testing, the use of dangerous, and Taobao’s suppliers are some Lingmai scattered individual operators, there is no formal after-sale security)
3. OEM manufacturer of notebook batteries: (formal OEM manufacturers manufacturing, but there are also some irregular OEM manufacturers. The use of the domestic market confusion, with split-core or use the old mechanical and electrical circuit boards, replacing them with newly plastic shell, and pasted into a OEM label and thus to deceive consumers)

The quality of non-original laptop battery to determine:
Non-original laptop battery is composed of roughly three parts: batteries, PCM plates, shell; Of course, these are also a direct impact on non-original laptop battery an important part of good and bad, Here I would like to talk about these important components of purchase of non-original laptop battery is Note that knowledge.

1. On non-original batteries, notebook batteries
Battery cells directly determines the quality of the non-original laptop battery capacity, endurance time and frequency of use, so the most important you should check is the battery cells when purchase non-original laptop battery, then we should check its safety, must be secondary protection, because the secondary protection is essentially to prevent the occurrence of an explosion, of course, to be built on the basis of good battery cells.
There are non-original laptop battery inside the insulating material is also very important, if the insulation failure, it is likely to lead to short-circuit batteries, so even if there are secondary protection, are more dangerous, so should be high temperature resistant insulating material, it is best to be fire if they are not in the laptop batteries were defective.

2. On non-original laptop battery PCM plates
PCM board determines the compatibility of non-original laptop battery. Typically, laptop battery production capacity is based on original laptop battery supplier information in the PCM board to write a program, this process need not be the same as original laptop battery, but it must be matched and the original notebook. Notebook is compatible with the need to test with the original notebooks, this process will increase the firms production costs. Under normal circumstances, notebook battery R & D were able to determine whether the new process is compatible with the original notebook, many small and medium manufacturers of notebook batteries original machine will dispense test the working procedure. However, not all businesses will dispense with this process, a number of large-scale and influential non-original laptop battery manufacturer in order to be responsible to consumers, will not hesitate to original cost of the testing machine in order to achieve perfection with the original laptop battery is compatible.

3. On non-original laptop battery shell
Non-original laptop battery casing material composition preferably also by the fire, so that only high temperature, the components inside of the laptop batteries have protective effects.

Non-original laptop battery market price:
After the above brief introduction, we would be able to know that a non-original cost of laptop batteries. The other two constituent materials can be ignored. In general: the materiel cost of a good quality  notebook battery (8 cells)  should be around 60 USD, so a good replacement laptop batteries (8 cells) ’s price, including operating costs and profits to reach the end consumer’s hands should be 70-80 USD; if it is low-quality goods, B-class laptop battery (8 cells) the materiel cost is 40 USD, the price for 50-60USD; if it is the lowest quality of Notebook Battery (8 cells) the materiel cost is about  for 25 USD, its price is usually between 30 -40 USD.

Plug the power adapter and the computer battery is fully charged, until the battery indicator light off and the adapter plug into the green light from the amber, which means that the battery is fully filled.

Disconnect the power adapter, use the iBook or PowerBook. When the battery power diminishes, the screen will show the battery power shortage warning dialog box. Continue to use the computer until it goes to sleep so far. At this point, the battery completely runs out for calibration.

Connect the power adapter until the battery is fully charged again, and then the unplug.

You must be completely filled with electricity, and then came alive again finished a battery in order to calibrate them. After that, you can charge the battery at any level when you connect and disconnect the power adapter.

Tip: When the battery is “empty”, the computers will be forced into sleep mode. In fact, the battery power is not really “empty”, but will retain some in order to maintain the computer to maintain a period of time in a state of sleep. Once the battery is truly exhausted, the computer will be forced to close. At this point, all open files will be lost. Therefore, before the mandatory shutdown power outlet and connect adapter to find is very important.

Experts teach you laptop battery repair method
First, why should fix laptop battery?

When the laptop battery without being used for a long time, or just maintenance, it need to have self-reply process, also known as calibration or self-learning process.

Because of his way of charging and discharging of the way or a curve, there will be a certain amount of cheap,therefore, the need for a truly finished a few full discharge cycle of steps to correct the situation or club the way the repair of charging and discharging of the square

Type of course, here, want to clarify is that your laptop battery is not an aging, if the laptop battery aging, and Oh, that would basically only be a change in the.

Concrete repair steps:

1. Setting
If the laptop battery should repair to the best state (no aging batteries), this is the most important place. Therefore, we should pay attention to.
(1) Open My Computer, Control Panel, Power Options Power use of the program, the use of batteries that
Full-time parameters entry named “never”.

(2) to alert that the project hook removed,
This is done to the battery when the laptop down to how many per cent when the program will not be executed.Laptop battery power to run a true After completion,there is no remaining power interference.

Charge-discharge description of specific steps:

In doing the above settings, On the full release in accordance with the principle of end to the battery charge and discharge, and laptop battery recall that bought back the activation steps,and my last time writing notebook battery is fully charge and discharge Gonglue do?
In accordance with that principle to the battery charge and discharge back and forth three times.

Be able to offset the curve of the battery to correct the fix coming.

Static electricity generation and trigger is a natural phenomenon, we can not be completely eliminated, but as long as usually more careful, it can be avoided. To deal with static electricity, we can take the “anti” and “release” hands. “Defense”, we should try to use cotton clothing and home accessories products, as the fabric, try to avoid the use of chemical fiber carpets and a plastic as the surface material of the furniture, in order to prevent friction electrification. “Release” is to increase the humidity, so that localized electrostatic easy to release. When you use a computer before, you should immediately wash their hands face, on the one hand to maintain a healthy, while also allows the electrostatic charge on the surface of the skin to release the water out. In the winter, we should try to use a high moisturizing cosmetics. Common humidifier. Some people like the indoor rearing ornamental fish and daffodils are also regulating indoor humidity a good way. The daily use of desktop computers and laptops, there are a few tips to note:

A notebook to make use of an external power supply

We know that the laptop will have in the course of currents, these currents can not be released if there is no conductor contact, if the encounter with the static electricity produced by the body, it will generate electrostatic discharge, resulting in blue screen, crashes. In view of this situation, it is recommended to use an external power supply, laptop power adapter three phase plug at the same time maintain a good grounding. Not only can effectively prevent the leakage, but also can prevent the accumulation of static electricity.

2, access to computers before discharge

Due to environmental dry friction, the body has accumulated a large number of charge, often in contact with notebook notebook damage caused instantaneous discharge occurred. Therefore uncertain whether the electrostatic accumulation of the body, first after the release of the body static electricity using a laptop. With the books before, it is best to wash your hands, water well to eliminate static electricity, especially in motion a long time (sports events to make clothes and friction, resulting in a large number of static electricity), after; if too lazy to wash your hands, then take a look around there is no ground metal objects can also have contact with both hands effectively eliminate static electricity. Also to be noted that as far as possible not to touch the books by hand directly connected with the internal circuit elements, particularly the interface, in the next, when particular attention to USB.

3, on a regular basis to the computer clean, efficient addition to static electricity

On a regular basis to the computer to do thorough cleaning, you can effectively reduce the accumulation of dust, while you can use anti-static cleaning materials for cleaning, to help reduce the accumulation of static electricity. Baxter clean your computer cleaning of the three detergents, all contain anti-static formula, can effectively play a protective effect, reducing static electricity, to protect the computer role.

How to deal with static electricity after a fault occurs

Notebook for everyday use, the most common are contact discharge, leading to a normal laptop can not boot. If this situation occurs, you can remove the battery after the elimination of its own static, unplug laptop power adapter, notebook and put it aside for half an hour’s time. Again after a separate access to the power adapter, generally can be a normal boot. If you still can not boot, or the repeated occurrence of the phenomenon of static electricity caused not boot and should be sent to notebook manufacturers to conduct a comprehensive inspection office, if necessary, some parts may need to be replaced.

Reviews:

This new HP Mini 5101 laptop is indeed a stylistic departure from the Hp 2140 series laptop, trading the gently rounded silvery metal look for a sharp-edged black brushed-metal chassis.

Bottom Line:

Can get very expensive once you start adding extras. The HP Mini 5101 is much improved version over HP’s previous netbooks, but you’ll have to pay extra for many of its fringe benefits—if they become available.

Pros:

Very attractive metallic chassis. 95-percent keyboard is right up there with those on the top netbooks. Mouse buttons are quiet. Bevy of options, including an “HD” resolution, 3G, SSDs and 7,200 rpm HDDs. Good performance scores. 802.11n wireless capability.

Cons:

Options can bring up the cost significantly and aren’t available for purchase yet.

The 6cells HP 5101 battery life and slightly improved performance, which puts it on the top of the netbook heap.

The Mobile PC Extended Battery Life Working Group (EBL-WG) announced that its low-power display program achieved a major breakthrough, confirming an average annual shipment of more than 600 million pieces of no more than 3 watts power consumption, low-power 12.1/14.1/15.0 XGA display, expected to account for the total notebook shipments in 2004 to about 12%. It can help many kinds of  laptop batteries to save power consume, such as Dell xps m1530 Battery, Dell Inspiron 1525 Battery, Dell xps m1730 Battery,Dell Studio 17 battery.
    From a year ago to establish the program began, the display of the average power consumption has dropped from 4.3-4.5 watts to 3 watts or less – power savings equivalent to an additional 60 minutes of laptop battery life. EBL-WG’s goal is to achieve an annual production of 1,000 early next year, 10000 no more than 3 watts power consumption display, expected to account for the total notebook shipments for 2005, about 20%.
    Intel’s Mobile Platforms Group, Mobility Enabling Initiative Manager and EBL-WG Chairman Kamal Shah said that the notebook computer display subsystem in notebook computers, the overall average power consumption occupies a large proportion. So far, notebook computers of the various components and subsystems, the display subsystem consumes the most power. Shah said: “With the new low-power display technologies emerge, the display subsystem must also consume less power, thus continue to promote the continued decline in overall mobile platform power consumption.”
    He said: “Consumers are demanding notebook computer with longer battery life time is increasing. If we are to achieve the ideal of all-day battery life, reducing the power consumption of notebook computer display subsystem is the key lies. ”
    EBL-WG milestone demonstrates manufacturers increasing desire to reduce platform power consumption to meet the users demand longer battery life. Recently joined the EBL-WG, several companies, including: AMD, ATI Technologies Inc, BIC, Infineon, Millennium Cell, Motorola Energy Systems Group, O2Micro, and Sion Power.
    Acer Value Creation Center (Acer Value Lab), vice president Arif Maskatia said: “We are increasingly popular mobile lifestyle demands anytime, anywhere access to information. Via Wi-Fi, Internet access is becoming increasingly easy and popular, we need to use more a long battery life to provide strong support, so that users can truly have a wonderful wireless experience. ”
    EBL-WG is extending its efforts in order to promote the industry to adopt its methodology for measuring battery life, thus will be able to notebook PC manufacturers to assess power consumption of different panels to provide a common reference. The group is encouraging all display panel manufacturers will be based on the criteria to measure the EBL-WG power to its product data sheet. The plan will support a comprehensive assessment of notebook computer manufacturers to display characteristics of the list, and in the same place to compile all relevant data to simplify the display verification flow.
    With regard to notebooks EBL-WG
    The Mobile PC Extended Battery Life Working Group (EBL-WG) is a global industry organization, the group of companies working together to extend notebook battery life.

Factors that can influence the  that laptop battery life – battery life did not meet expectations

When we are using notebook computers, some factors that make the battery wear and tear, and even may lead to the maximum use of time lower  than standard batteries, but it does not mean that these factors may damage the battery.

There are many kind of  batteries such as Sony VGP-BPS8 battery,Inspiron E1505 battery,Dell  6400 battery, DELL XPS M1730 battery , their life are affected by many factors.
The factors that affect battery life are:

Factor 1: the processor speed – Right operation  to install Intel chipset drivers make systematic use of Intel Speed step technology for processor speed adjustment, which will extend the application system battery life.

Factor 2: CD, DVD, CD-RW and hard drive frequency reading – trying to directly copy the CD files to your hard drive to operate (including copy, delete, and run an application, etc.) will improve the battery life.

Factor 3: the total number of memory and memory – if the system opens a lot of applications will take up a lot of hard disk space to do file-swapping (virtual memory), resulting in frequent hard disk read and write, then the more memory on the right battery use time more useful.

Factor 4: Some applications to run automatically in the background, it will increase the CPU load, resulting in reduced use of time – usually recommended when using some of the background programs that run off, only to run the necessary applications.
Factor 5: LCD’s brightness – the lower the brightness settings for battery use a long as possible, you can use to use FN + key or under the direction of brightness adjustment keys.

Factor 6: Power Management and Speed Step settings – in the power management settings of different power scheme will affect battery life.

Factors 7: battery life – the average battery life is one year, with the use of time and frequency increases, the gradual reduction in battery usage time is normal.

Factors 8: For the processor and system equipment deeper applications (such as watching DVD movies and 3D games) will make the time available to quickly lower the battery.

Factors 9: wireless devices and Bluetooth devices will accelerate battery consumption; do not need wireless, you can use FN + F2 turn off to save power.

Factors 10: use of environmental temperature – too high or too low, the use of ambient temperature will affect battery core activity of chemical substances, thus reducing the battery usage time and life.

Similarly, the battery life also depends on different system configurations. Take Inspiron6000 examples:

Configuration 1: Pentium M 730, 15.4 “WXGA, 512MB, 64MB ATI x300, 30GB, DVD-ROM / CD-RW, 6-cell battery
Can be 3.5 hours (maximum battery time in the 3:37 to 3:50 hours)

Configuration 2: Pentium M 730, 15.4 “WXGA, 512MB, 128MB ATI x300, 30GB, DVD-ROM / CD-RW, 9-cell battery
Available at 5:21 hours (maximum battery time, 5:13 to 5:21 hours)

Configuration 3: Pentium M 730, 15.4 “WXGA, 512MB, 64MB Intel UMA, 30GB, DVD-ROM / CD-RW, 6-cell battery
Available at 3:55 hours (maximum battery time, 3:42 to 3:55 hours)

Configuration 4: Pentium M 730, 15.4 “WXGA, 512MB, 128MB Intel UMA, 30GB, DVD-ROM / CD-RW, 9-cell battery
Available at 5:40 hours (the longest battery time, 5:32 to 5:40 hours)

Configuration 1 and 2 is mainly directed against an independent graphics system (different memory), for 6-cell and 9 cell battery usage.

Configuration 3 and 4 is the system integrated graphics (Intel chipset integrated graphics), for 6-cell and 9 cell battery usage.

Comparison shows that 9-cell battery roughly 6-cell battery than the increase of nearly 30% of usage time.

Similarly, by comparing cross-* (1 and 3, 2 and 4), using the same capacity battery, stand-alone graphics card because the application of additional memory and display chip, the battery will cause the loss of a small magnitude. (5-20 minutes or so)

1, Concept of ACPI

ACPI: Advanced Configuration and Power Interface

There are several modes of ACPI:

S0 to normal.
S1 CPU to stop working.
S2 CPU shut down.
In addition to memory outside the S3 components are to stop working.
S4 memory write information to disk, all the parts stop working.
S5 closed.

ACPI power management mode to use hardware and software requirements can be fully supports the ACPI function.

If you encounter problems in use, you can try to upgrade the latest Acpi.sys file.

In addition, the hardware of the ACPI support is essential. Chassis power supply 5 volts to the motherboard at the same time, we must make current stabilized at more than 720 milliamperes to be able to make a computer in a short time from the “sleep” state wakes up.

The program can be achieved by selecting the power supply power management, power management program is the computer power on the use of a group of settings. Windows2000 provides the following three kinds of preset power management program (always open, portable / laptop, home / office desktop), the user can also set up their own computer into standby mode or turn off the hard drive and monitor the waiting time required.

2, ACPI and APM Comparison

APM 1.0 & 1.1: the implementation by the BIOS Power Management;

APM 1.2: operating system, the definition of power management time from the BIOS is responsible for implementation;

ACPI: BIOS collection of hardware information, define power management solutions; by the operating system responsible for the implementation.

APM is a software solution, therefore, with the operating system-related, but ACPI is an industry standard, including software and hardware specifications.

1) How to determine the system is in S1 or S3 mode?

A: The S1 sleep mode, ACPI, only the CPU to stop working, other equipment are still in power-up state. The S3 in the ACPI mode (BIOS-> Power Management -> Suspend to RAM set to Enable, among other equipment are situated outside the memory power-down state. Therefore, to determine the system is in S1 or S3 mode mode The easiest way is to carefully observation system situation: In the S3 state, all the equipment to stop working, even if the pop-up button on the drive can not open the drive door. In the S1 state, optical drive door is open. In addition, S3 mode, the system is completely quiet , all the fans are stopped. At this point system can not wake up from the keyboard. manual method can only be awakened by the power button on the front panel.

2) To achieve STR, so why not cut off the power after shutdown?

Answer: STR function is turned off, it will be the operation of the system information stored in memory, the next boot directly read the memory information, and return to pre-shutdown state. Its advantage is to start very fast, and can keep working condition. The disadvantage is that, even after shutdown, we can not disconnect the computer power supply. Because the data in memory will be lost once the power cut off.

3) In the closing Win2000, display “now safe to shut down” instead of automatically close ATX power supply, how should I do?

Answer: can try the following approach: choose “Settings / Control Panel / Power Options / Advanced Power Management”, if the machine supports advanced power management, then select the “Enable Advanced Power Management Support” and then in the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon Mid PowerdownAfterShutdown for 1; if the machine does not support advanced power management, then, unfortunately, only in the closed system, the display “now safe to shut down?” had to manually cut off power supply.

4) does not care to “Close Windows” dialog box “Let the computer to sleep” to the lost, and ask how to restore?

A: Generally speaking, such problems as long as the reinstall motherboard drivers, restart the future should be able to solve the problem, you can also “Control Panel / System / Device Manager” in the “Advanced Power Management support” deleted, and then Reboot the machine, according to Windows2000 system can also be prompted to re-install solve the problem.

Apple news:

December 30, according to foreign media reports, following the “iSlate”, the Apple Tablet PC has a new candidate before the name of “iGuide”.

Some analysts predicted last week, Apple Tablet PC is likely to be named as “iSlate” next year. In 2007, Apple bought iSlate.com domain name in preparation for the release of new products. “Slate” a “slate” or “board” means, as the name of the Tablet PC is quite appropriate.

But on Tuesday, analysts have pointed out that Apple has registered the “iGuide” trademark. From the trademark classification and other relevant information to determine, this is likely to be the official name of Apple’s tablet PC.
