Notebook battery fully charge and discharge error

Posted on September 1st, 2010 in battery tip | No Comments »

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of laptop battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of latitude D830 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the inspiron 1520 battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the VGP-BPS5 battery’s “charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the Satellite A100 battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.

Zinc stranded Laptop battery

Order to prevent the risk of further deterioration of the financial turmoil triggered deep-seated economic problems, the Fed announced an emergency rate cut this week in two 75 basis points, to a certain extent, eased the panic in financial markets filled with emotions, the world’s major stock markets have rebounded fujifilm np-95, after following the oversold Yang received. Despite the panic around the popularity to be a little relaxation, but the overall trend is still Zoudie zinc City Channel, lun 3 weeks straight zinc has dropped, the cumulative drop of 235 U.S. dollars / ton, the lowest point (2160 U.S. dollars / ton) touched the bottom of the support line (Zhou K chart, February 17, 2006 and November 23, 2007 low of connections); Shanghai zinc index fell for two consecutive weeks, the cumulative fall of 1618 yuan / ton, the lowest point (17,776 yuan / ton) are also the formation of the bottom of the support (17.6 thousand yuan / ton in the vicinity) stress test. Overall, zinc City last week, showed significant support will retest of the lows.

For the next week, zinc City, the trend caught on because canon nb-6l of their multiple negative factors, will continue to support the wishes of the performance of retest of the lows. Multiple adverse factors are beyond our focus is: the continuing turmoil in the macroeconomic environment; supply and demand data reproduce the excess pressure; investment funds, the formation of bottom pressure of a high position.

First, while the Fed’s emergency rate cut to a certain extent, to prevent the U.S. economy sliding into recession may fast, but monetary policy was helpless further exacerbated by global inflation. At the same time, investors are still worried that the collapse of the U.S. housing market has exposed the questionable mortgage casio battery , casio np-100 lending standards for the industry, followed by credit cards, auto loans and student loans could be the next troubled industry, which make the financial system and economically difficult.

Secondly, the China Nonferrous Metals Industry Association latest statistics show that in 2007 China’s zinc output of 3.714 million tons, increased 17.8% compared with 2006, the average monthly output of 33 million tons. Although the zinc price suddenly dropped from the primary and secondary smelters cut production starting in November or even stop production when compared, the market is estimated that in 2008 a quarter of the average monthly production will decline to 30 million tons, but the overall situation of the domestic surplus in 2008 to show greater pressure (07-08 zinc futures first annual report are described in detail sony vgp-bpl8 , sony vgp-bpl8a), while in 2008 the domestic regulation and control policy tightening will make the “China factor” strong demand growth in the supply of hard to arrival. Therefore, the excess pressure on zinc price to find strong support for retest of the lows.

Finally, the zinc municipal positions rising, while zinc prices have consistently fallen. This shows that most investment funds to see the empty zinc prices, see the empty pursuit of money and zinc prices will also seek a strong support base. From a technical trend of view, careful test of their ability to support LUN zinc 2000 (I pessimistic about the material in 1800 is expected to form a more powerful support), Shanghai zinc 16,600 yuan / ton (pessimism 15,000 yuan / ton sony vgp-bps9). Operation, I believe that Shanghai more than one-zinc reduction or leave the air rallies admission alone. Operational strategy, risks remain due to shock, short-term operation is appropriate.

Improving apple notebook by calibrating your battery

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

The battery has an internal microprocessor that provides an estimate of the amount of energy in the battery as it charges and discharges. The a1175 battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate and to keep the battery operating at maximum?efficiency. You should perform this procedure when you first use your computer and then every few months after that. If you normally leave your Apple portable computer connected to AC? power and very rarely use it on battery power you may want to perform this process once a month. The website?www.apple.com/batteries?has more helpful information regarding batteries and offers an iCal calendar to remind you to calibrate your battery.?

Note: If you’re not sure which model of PowerBook you have, see PowerBook G4 Computers: How to Identify Different Models for assistance.

Products Affected

iBook, MacBook Pro, MacBook, PowerBook, MacBook Air

iBooks and PowerBook G4s other than the PowerBook G4 battery (15-inch Double-Layer SD)

  1. Plug the power adapter in and fully charge your computer’s a1185 A1022 battery until the battery indicator lights turn off and the adapter plug light goes from amber to green, which indicates that the battery is fully charged.
  2. Disconnect the power adapter and use your iBook or PowerBook. When your battery gets low, you will see the low battery warning dialog on the screen. Continue to use your computer until it goes to sleep. At that point the battery has been sufficiently drained for calibration.
  3. Connect the power adapter and leave it connected until the battery is fully charged again.

You have to fully charge and then discharge your battery only once to calibrate it. After that, you can connect and disconnect the power adapter when the battery is at any charge level.

Tip: When the A1175 A1185 battery reaches empty , the computer is forced into sleep mode. The battery actually holds a reserve beyond empty , to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, any open files could be lost. Therefore, it is important that you find an electrical outlet and connect the adapter before the forced shutdown occurs.

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new A1079 battery released with this computer. With these computers, follow these steps to calibrate your battery:

  1. Plug in the power adapter and fully charge your PowerBook’s battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
  2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
  3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
  4. At this point, save your work.? Continue to use your computer; when the PowerBook G4 battery gets very low, the computer will automatically go to sleep.
  5. Turn off the computer or allow it to sleep for five hours or more.
  6. Connect the power adapter and leave it connected until the battery is fully charged again.

Tip: When the battery reaches empty , the computer is forced into sleep mode. The A1079 battery actually keeps back a reserve beyond empty , to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer’s memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.
