# Why Does My Laptop Battery Drain While It’s Shut Down?

My Windows laptop loses a noticeable amount of battery overnight even after I choose Shut down. It’s worse if I’ve used it during the day, but I can’t tell whether the battery is simply aging or whether the computer isn’t fully powering off.

Could **Windows Modern Standby**, connected peripherals, or a firmware setting explain this? I’m trying to work out what to check before replacing the battery.
