How to Know When It’s Time to Replace Your Laptop’s Battery; Windows Will Warn You

Windows doesn’t usually keep you up-to-date with your battery’s capacity level. As you use it and it weakens, you’ll just notice that your laptop battery doesn’t seem to last as long as before.

Eventually, when your battery reaches a low enough capacity level, Windows will warn you. You’ll see a red X appear on the standard battery icon in your system tray and, when you click it, Windows will inform you that you should “consider replacing your battery.” Windows also says that your computer might shut down suddenly because there’s a problem with your battery, in other words, your battery can’t hold enough of a charge to power your laptop for long when it’s not connected to an outlet.

Note that this warning was added in Windows 7, so you won’t see it if you’re using Windows Vista or XP.
