Some time ago have been rumors that Windows 7 may damage the laptop battery does have friends around a similar phenomenon, but in the end is the Windows 7 ruined the battery or the battery itself is really bad, this issue has been the focus of controversy, in fact, I feel that the system the possibility of ruining the battery is still small, if the system is really capable of such things, chances are as early as 2000, XP era appeared, and why he waited until now.
Later, on the Internet that Microsoft engineers, a Blog, which explained in detail this problem happens I also subject to Microsoft entrusted to the translation of this article was finished, so let it out for your information, the so-called eyes of the beholder wise, see chi the letter the letter be good worth mentioning, in short, the user's an explanation.
My English is limited, we can see if the translation is wrong, as long as does not affect the original intent, or to laugh it off, or else tell me secretly is also doubtful.
The author is Steven Sinofsky, the Father said was responsible for the largest first few Windows products, the old fiercely ... ...

In the past week, we saw in the blogosphere some information on Windows 7 and ASUS EEE PC 8G Laptop Battery active topics, especially on "Please consider replacing the battery" in the new Windows 7 news. Since this is a topic on the Windows 7 project, we will use this blog to provide people with updated information. As we have mentioned many times, we will always be committed to enhancing the quality of Windows 7, and take seriously any of the reports we receive, these reports will identify potential problems, and these problems may lead to systems failure. In previous posts, we have spoken about when we receive the report of the Bug, especially when we begin to see some reports seem to indicate that the same issue, we will take what steps. Over the past week or so, we have been working hard through these steps and to view more content, we would like to learn more about this problem in Windows 7 Is there any where we need to resolve. At this point, we have no reason to believe that in this case there is any battery about Windows 7's.
Users posted in the blog and forums claim that Windows 7 warning them that "Please consider replacing the batteries", while in the upgrade to Windows 7 prior to this problem did not occur, this situation has caused in the past week the attention of a number of newspaper articles . These articles described in the posts in support of the Forum, said Windows 7 is not only warn those people with defective batteries the user - that's what we work for the design of Windows 7 - but also hinted that Windows 7 In response to this State made the wrong The report even worse, resulting in damage to these cells. To make everyone in this circle in a good understand - Windows 7 on the battery warning issued by the right, because it is really bad, Windows 7 is neither made an error report on battery status, nor by any way leading to cell damage. In each case, we have been able to confirm those reports are in fact necessary to recommend the battery replaced.
To use all the tools at our disposal, including the links in the forum report this issue to customers, customer service, communication, and our computer manufacturers, of course, also included in the Windows 7 in the telemetry, we have been monitoring reports, and on this a new feature to discuss, try to demonstrate that Windows 7 may lead to behavior problems in the report of open division. In the latter case we are trying to understand the scope of its application, and access to hardware in order to reproduce the error behavior. To date, all of these steps that we have done a customer in the battery health problems described in the report content, and in all cases, we investigated the Windows 7 is very accurate to detect a defective battery. Before I begin talking about the state of this particular problem, we should first look at the details behind this new feature.
The computer battery life (you are using battery power run time), the most obvious component is one of the battery itself. The capacity of the battery in the computer itself, the degradation is used to charge and the provision of electricity (like all rechargeable batteries do). The reason is that complex chemical changes in the IBM THINKPAD T60 Laptop Battery includes irreversible changes, as well as an increase in internal resistance, in addition to depending on battery design and manufacturing. On the user's computer in such a degradation in terms of battery life will reduce the battery life. Eventually, the battery must be replaced, so the computer can only be restored to an acceptable battery life. A quick check mainstream notebook PCs, will see the battery usually a 12-month warranty, which on the length of battery life, but also by the statistics that we can come to accept the apparent degradation of the battery length of time (which means that you began to pay attention to the need for more frequent recharge). Such as ours have been using the same one laptop computer (or cell phone, music player, or any other necessary equipment for rechargeable batteries) in 2023, and to take frequent repetitive charging, there is no doubt that you can "feel" to the battery life of attenuation, in the absence of any information provided to us under the premise of reference that we can be attributed to the attenuation of the battery life of any element.
Windows 7 uses a new laptop battery function, this function of the circuit and firmware can give Windows a comprehensive report on the health degree battery. This is the use of kilowatt-hours (W-hr) in absolute power capacity calculation. Windows 7 On this basis, do a simple calculation, the original design capacity of the battery, based on accurate and calculate the current capacity fade percentage. In Windows 7, we set up a 60% decay rate of the threshold (that is the battery available capacity is only 40% of design capacity), and Windows 7 will help you interpret the report. At this point, for example, a battery charging could have provided after 5 hours of electricity, but now, on average, only about 2 hours. Windows 7 in the battery in the notice is the battery meter icon and it sends the notification message, "Please consider replacing the battery." This notice is the new Windows 7 features, in Windows Vista and Windows XP, does not exist.
PC battery by system firmware (or BIOS) on battery capacity and health reveal the degree of information. In the Firmware Interface (ACPI) on the detailed specifications, but the most local level, the hardware platform and firmware provides some read-only regions, these areas describe the battery and its state. The firmware provides a battery of information, including manufacturer, serial number, design capacity, and the last full charge capacity. The last two parts of the information - the design capacity and the last full charge capacity - is Windows 7 is used to determine how many cells have naturally attenuated. This information is read-only, and no way to make Windows 7 or any other operating system to prepare, set up or configure the battery status information. In fact, all pairs of battery discharge behavior is completely controlled by the hardware in the hands of the battery. Windows reports that it can only be read from the system firmware in the battery information. Some reports erroneously claimed, Windows proposed to amend the information, it is absolutely impossible.
As mentioned earlier, every one we have received the relevant report, we only see the new features in Windows 7 to use this report on the status of the battery, and we see that the battery described in the report did not reach the specified threshold . Here we will discuss the specific data to support this view. Some users in the previous system, all normal, in the upgrading of the computer system after seeing such a warning would be surprised, of course, it is very reasonable. Essentially this is because the attenuation caused by the battery, but for the users of this decay is not obvious, difficult to detect until the Windows 7 provides such information have changed. We recognize this feature in Windows 7 a "cause" changes in performance, but in fact doing all the things Windows 7 only reports out of those who have already happened.
The following data points help us to understand that the report of the information. Keep in mind that all we see are optional telemetry to join, anonymous, and follow the privacy policy.
* We have already seen on this report did not notice the new hardware or recently purchased a computer to reproduce. Although we have seen some reports that the new computer has received the notice, but in all instances, we have confirmed that those cells already in the state of decay.
* Our OEM partners have to use their telemetry (call center, support forums, etc.) and have already let us know they did not see any circumstances beyond their expectations. It is noteworthy that computer manufacturers for the customer to solve the battery problem, get a clear view of that both in the general area or in a specific model, a timetable and batteries in the end what was expected.
* We passed all the major online support and self-help forums, and has been working at the appropriate time to follow up any errors displayed on this notification has been reported. Through this work, we have identified a new battery or the computer does not reproduce the problem described in the report and only learned that the battery capacity is indeed attenuated.
* In our telemetry from the RTM customers, only a small percentage of users receive a "Please consider replacing the battery," the notice, as expected, we see these systems are used for more than 1.5 years. Compared with the pre-release version, we see relatively fewer of the notice, as to reduce the average age of the system as.
* Microsoft has received 12 customer service events, in addition to various other forums from the eight additional events. So far (a total of 20 events), these events do not show an addition to the battery for any reason other than degradation.
* Microsoft TechNet moderator of the community has been used to assist in further contact customers about this notification, report that we have the designation of additional customer service personnel to prepare for this matter. In any case, we have received about 30 contacts, which did not find any notification on the new arguments or status.
* On Windows 7 pre-release version of the test, will indicate the notice, we can see with our customers almost exactly the same experience. In fact, look at the pre-release testing of the hardware sales, we can see that the system received the notification to maintain a constant very small increase in number. From this realistic point of view, a large number of customers purchased a new computer, Windows 7 or in recently purchased a computer using Windows Vista upgrade available.
* During the inspection, this shows that this notification, the telemetry equipment reports, we do not see any additional reliable data show that any other system abnormalities.
* Although the battery status information available through the ACPI operating system is read-only access, we conducted a thorough code review and verification to determine that there is no ability to change the battery status information code.
These data will confirm our view, we only see the emergence over time the normal degradation of the battery. In this new Windows 7 features provided in the transparency of the technologies used to produce a notice, which in the past is not visible to customers, but after the upgrade to achieve quickly. This is what we see in these emergency root causes of posts, but were unable to change the SONY VGP-BPS5 Laptop Battery status of reality. We have not confirmed the purchase of new machines and the battery situation.
As we have said about the quality of any reports of Windows 7, we will continue to diligently to treat, when the report of potential problems, we will use all the tools at our disposal to clear it from the bottom, in the need for code changes, we will be improved and released to the customer. We are sure that because we can, we are concerned about this report, and to fundamentally solve the problem, but we will continue to monitor the relevant circumstances. In particular, we will continue to work with our OEM partners, communication and contact, they will be closely monitored to their customers and computer.
