One of the shortcomings of Windows Vista is that it is difficult to maintain the battery consumption of the notebook. Although Windows 7 has improved productivity through the fix, it seems that the battery is not taken seriously. More and more reports recently show that Windows 7 has severely shortened battery life. Currently Microsoft has announced an investigation into the issue.
Here are some finishing Windows7 problems with a battery:
January 12 issued a statement against Microsoft Windows7 affect battery incident and launched an investigation.
before this Windows7RTM released in October, declining battery life problem has emerged.
on January 1 this year, began to have friends in response to this question TechNet forum, which the user (screen name dabruton) said he bought himself a 2007 HP laptop to upgrade from WindowsVista Windows7 However, the battery life has changed from two hours to just half an hour, and Microsoft has repeatedly promoted the new system to greatly extend battery life. The user said that powercfg's energy report shows that the Windows 7 full-charge state is 40% lower than the normal full charge.
reported that the root of the problem is Windows7 adds a new battery detection tool that can determine whether the battery needs to be replaced and notify users, but in some cases, even though the battery business as usual, the system will determine the error that the battery Already exhausted, and it is recommended that the user replace it immediately, and sometimes even shut down the system directly. Some users reluctantly said that he did change the old battery after seeing the prompt, but the new battery continued to receive the same warning.
Some people say that this problem existed Windows7Beta early testing phase, but others say that RTM only appear in the official version. One user posted: "My battery life has been normal before installing RTM version of Windows 7. I can hold it for almost three hours in all the Beta and RC versions I installed. Now, it only takes about twenty minutes for Windows7. I took the laptop to shut. this situation is occurring in the RTM when I turned from the RC. Needless to say, I and everyone else very unhappy. "
Microsoft said in a statement that has been known This problem is related to the way Windows 7 reads the system firmware, and it exists on different models of notebooks from many manufacturers. Microsoft said: "We are investigating this issue with our hardware partners. Windows 7 uses firmware information to determine if the battery needs to be replaced. We are working with our partners to find the source of the problem, and after getting the information and guidance we need, we will be at (TechNet) Forum. on the update. "
Microsoft also claims that, sometimes this new tool is working correctly, in other words if it prompts you to replace the battery, chances are that your battery really have to hang up, but apparently by mistake The chance of reporting is too high.
this issue we can only hold onlookers attitude, what will not cause hardware damage caused by the software, is still not clear.
