Microsoft faces Windows 7 battery problems
Microsoft officials recently confirmed that they are looking into reports of radically shortened battery life on some laptops after installing Windows 7.
Users reported on Microsoft TechNet that their batteries were working just fine with Windows XP and/or Windows Vista. However, on Windows 7, the users are confronted with a warning message saying, “Consider replacing your battery. There is a problem with your battery, so your computer might shut down suddenly.”
