1.Go to Control Panel->Power Options->Change Plan Settings->Change Advanced Power Settings
2.Go to Battery->Critical battery action and then set what you need. Also try setting the Low Battery Notification to On.

Also check if your battery has worn out, that maybe a possibility!

The battery may need calibrated (fully charge it, then FULLY discharge it, and fully recharge it once more). Sometimes this % is incorrectly reported to the operating system.

It's possible the problem is an electrical nuance and not per calibration.
