Hi, its just as the title says. I say it because all three years, I used xp and vista and suddenly had to skip to win 7 due to a major problem. But 2 months after the install, my laptop suddenly showed, "Consider replacing your battery" error. Did anyone else experience this after installing windows 7? Is it something related the OS? Or is it just our battery problem? What did you do to avoid this? Did you ever solve the problem? Which OS is better so that our battery has long life?
