There was no battery warning from Windows—in fact, you recently checked and Windows said you had 30% battery power left. Even if you treat your laptop’s battery properly, its capacity will decrease over time.

Its built-in power meter estimates how much juice available and how much time on battery you have left—but it can sometimes give you incorrect estimates.
