Abstract

You can calibrate iBook, PowerBook, MacBook MacBook Air or MacBook Pro computer’s lithium-ion battery for optimal performance.

The battery has an internal microprocessor, can be provided when the battery charge and discharge the battery in the power of the estimated value. Battery needs to be re-calibrated from time to time in order to maintain the screen battery time and percentage of accuracy and to ensure that the battery is running the most efficient. You should first use the computer to perform this procedure, executed once every few months later. If you normally connect to the Apple laptops AC power, but rarely use battery power, then you may need to run once a month this process.

Affected products:apple A1185 battery, Apple A1189 battery, Apple MA458 battery, Apple M4685 battery

iBooks and the addition PowerBook G4 (15-inch, double-layer SD) other than the PowerBook G4 computers

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.

Once the battery is truly exhausted, the computer will be forced to close. At this point, PowerBook G4 (15-inch, double-layer SD) sleep, the computer starts security features, the computer memory, the contents will be saved to the hard disk drive. When the power is restored, the computer will use the hard drive in the safe sleep image automatically return to their pre-sleep state.

Apple A1189 battery news:

Many notebook users upgrade to Windows 7 from Windows XP / Vista discovered, the new system severely shorten the Apple M4685 battery life.

Official Microsoft TechNet forums, there are users post and said he put himself in 2007 bought an HP laptop to upgrade from Windows Vista to Windows 7, but the  Laptop battery life but never became a mere two hours, half an hour, but Microsoft is repeatedly promote the new system which can significantly extend the Apple Powerbook G3 battery life time. Other parts of the web forum had a similar question.

It is reported that Windows 7 is the root of the problem and adds a new battery testing tool that can determine whether the battery needs to be replaced and inform the user, but in some cases, even though the Dell Studio 1436 battery business is as usual, the system will judge whether the error that the battery has been exhausted, and recommended that users immediately replaced, and sometimes even directly shut down the system. Some users reflect the frustration that he did you are prompted to replace the old battery, but the new battery or continue to receive the same warning.

Some people say that this issue as early as Windows 7 Beta testing phase existed, but some say that the official version of RTM where phenomena which was Posted by a user and he said: “In the RTM version of Windows 7 prior to installing the Dell Studio 1435 battery, I have been normal, in my installation of all the Beta and RC versions where can persist for nearly three hours. Now, only had about 20 Windows 7 minutes to put my notebook shut. This situation is in my shift from the RC occur when the RTM. Needless to say, I have a very bad mood like everyone else. ”

Microsoft said in a statement that the problem has been known and noted, and Windows 7 read the way the system firmware in many different types of notebook manufacturers are present. Microsoft said: “We are working with hardware partners to investigate this issue. Windows 7 with firmware information to determine whether the Dell Studio 14 battery needs to be replaced. We are working with partners to find root of the problem, to obtain the necessary information and guidance and then go in (TechNet) Forum Update. ”

Microsoft also claimed that sometimes the new tool is working correctly, in other words, if it prompts you to replace the Asus N10J battery, it is possible your battery really has to be hung, but the chances of false positives is clearly too high.

If your mobile phones, digital cameras, notebook computers are unexpected watered, and this time you should never panic, immediately shut down the running of electronic equipment, and remove the battery, CD, SIM cards, memory cards, etc., if it is notebook computers , you’d better take out any removable things (especially the water part), and then the water dried.

Drain water, the following methods:

1, the use of desiccant, desiccant can siphon off water vapor and liquid. The bag of silica gel and the splashing of water into the electronic equipment at the same time sealing the mouth of the bag. Only without the used bags of silica gel to be effective – have been used not achieve much of a role. The silica replaced the ordinary uncooked rice and even salt can also be simply to ensure that they do not enter into the electronic devices (you can use tissue paper to wrap electronic equipment).

2, using 99% concentration of alcohol absorption. You can complete a wet electronic equipment dipped alcohol (using 99% rubbing alcohol concentration, rather than the ordinary 70% concentration of alcohol), you can suck the water out, to ensure that action must be quick, because alcohol may damage some some plastic products.

3, using heat to evaporate the liquid. The electronic equipment in the car dashboard to place a period of time (temperature shall not exceed 150 degrees Fahrenheit), can also splash the water into the oven where the equipment, the temperature not higher than 150 degrees Fahrenheit, throw in a period of time, if it is cell phone into the water, you can put it in your trouser pocket inside cover their dry, you can also use the hair dryer (temperature shall not exceed 150 degrees Fahrenheit), remember to follow any of the above methods before, we must remove the battery.

4, if the electronic device is a keyboard, and turned it over a period of time, perhaps the liquid can flow from the inside out.

5, if the laptop computers or mobile phones, splashing into the viscous liquid (such as soda water), then after drying also need to clean them is: to splash the liquid dismantling of equipment, with a 99% dip the cotton swab brush rubbing alcohol concentration scrub – otherwise, electronic products, probably because of residual goo and short-circuit.

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.
Presented here addresses http://www.hunt360.net  battery is very cheap and high quality here. Hp mini 1000 battery, DELL XPS M1530 Battery, Sony VAIO VGP-BPS8 Battery, Dell inspiron 6400 Battery

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.

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.

    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.

IBM’s Battery MaxiMiser software- repairing battery capacity!

I believe a lot of friends that the thinkpad t20 Battery is a gap between standard capacity and actual after some time! Battery MaxiMiser software in the battery status is divided into red, yellow and green. Green represents normal, yellow, and red represents a large gap between the standard capacity and actual capacity, the battery is not in health status, if your battery is a red state, then your battery life also is running out! Yellow is relatively better than red!

In fact, IBM’s own software, there is the thinkpad r50 Battery MaxiMiser repair option, you may rarely use, may never used! This recovery can restore some of your battery capacity! Health status of the battery so that you have some recovery, which is the battery standard capacity and the actual capacity of the existing gap becomes smaller!

This restoration of the situation for the red and yellow friends have a very significant role, for the green status of the battery might not have much effect!

Please note:

1. To use battery life to 3% of the state, and then plug in the Solar battery charger to start charging.

2. At this point with the mouse to click the task bar battery, select Battery Information.

3. The battery time- then choose the button under the Battery health.

4. At this point you can see your battery health status, select the button to Improve Battery health.

5. Final choice Thinkpad t60 battery reconditioning new button, point to determine!

At this time in the task bar, on the battery charge display signs next to the AC power supply will be more a sign of the emergence of a battery cycle! Repairing of battery capacity begins! Sometimes the repair process such as the computer automatically discharge the battery is full and then repaired, until the circle icon go away, it is proposed in this process and we should not turn off auto-repair!

Stated in a note in the software, if you frequently used Dell Studio 17 battery, the monthly battery should be repaired three times for the battery status of the most obvious red, you can upgrade the existing capacity of the battery 1-3 times ~ (referring to the battery is red state, but on many occasions after the repair of the effect)

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)
