The Windows 10 Alarms & Clocks feature is a simple and efficient app. It lets you know when you should take a break or join a meeting without having to use an additional device or install any software. So when it stops working, you should quickly fix it, so it doesn’t affect your schedule.

In this troubleshooting guide, we’ll take a look at what might cause the Alarm & Clocks app to malfunction and how to get it working again.

1. Check Alarm Settings

Before going into the troubleshooting process, let’s make sure your problem isn’t caused by incorrect settings. Launch the Alarms & Clocks app and double-check the time, day, and alarm sound. If everything looks good, move on to the solutions listed below.

2. Disconnect Headphones or Speakers

If you’ve connected an audio playing device to your computer, the alarm sound will be played through it so you might miss it. Unless you are using your headphones, you can disconnect them.

The same goes for Bluetooth or external speakers, especially if you’ve moved your laptop to a different room. Also, check the sound volume. If you’ve set it too low, there’s a chance you will not hear the alarm.

3. Change the Alarm Sound

While it may be odd, the Alarm app sometimes stops working on a Windows computer because you’ve changed the default alarm sound.

Launch the Alarms & Clock app and click the Add an alarm button. In the Edit alarm window, open the Alarm Chime menu and select Chimes, which is the default alarm sound on Windows 10.

4. Make Sure Your Computer Stays Turned On

If you’ve set the alarm but don’t use your computer for a while, it could enter Sleep mode and the alarm will not go off.

To change when your computer enters Sleep mode, right-click the battery icon from the taskbar and select Power options. Then, click Change plan settings and set a new time for Put the computer to sleep.

You should set a new time for On battery and Plugged. If you are using a laptop, you can stop it from entering Sleep mode when closing the lid.

Note: If you switch between two or more power plans, you will have to make the changes for every one of them to keep the alarm working.

5. Disable Focus Assist

If you’ve turned on Focus Assist or set it to show only high-priorities notifications, you will miss your alarms. In this case, simply turning Focus Assist or configuring its settings will fix the problem.

Go to Settings > Systems and from the left-hand menu, select Focus Assist and turn it off or select the Alarms only option.
