On Monday, Microsoft alleged that the warning regarding the replacement of the batteries built into Windows 7. Last week there were many reports from users who have received warning of the need to change the battery on your laptop or netbook. Warning appears when the BIOS detect the need to replace the battery. Windows 7 displays the subsequent warning: "Consider replacing your battery. There is a problem with your battery, so your PC might shut down suddenly." (“Think about replacing the battery. With your battery has problems, so that your computer may unexpectedly shut down.") Some people claim that their battery is usually worked two hours, ended after 30 minutes, while others threaten a lawsuit, assuming that the largest producer of software "forever damaged" batteries in their laptops.

Microsoft employees have reported that they had thoroughly investigated the issue and found no problem with Windows 7. "In each case, which we were able to determine the battery really needs to recommend a change", ─ said Steven Sinofsky (Steven Sinofsky), president of Microsoft Windows. In a company blog Sinofsky also said: "What is the best ecosystem, Windows 7 correctly warns of batteries that would otherwise cease to operate, and Windows 7 is not correctly reported on the status of the battery and no way is the achievement of the battery status."

Microsoft received 20 reports of incidents of customer service and reported that none of them had something else in addition to degraded batteries."Notifications seems to work as they were created to do what we can see", ─ spokesman said Microsoft. A Microsoft representative said that the messages that were found on the Internet, we can conclude that they are "from people who do not understand that this is a new feature in Windows 7, which simply was not available before."
