How to use Alarms & Clock app
Dismissing or snoozing alarms
When an alarm goes off, you’ll hear a sound and see a notification that you can snooze or dismiss.
It appears even if the app is closed, sound is muted, or your PC is locked. You can even dismiss alarms from the lock screen without unlocking it. However, in most cases, alarms won’t sound if your PC is asleep, and never when it’s shut down.
Notes: Some newer laptops and tablets have a feature called InstantGo, which wakes up the device to sound an alarm even if the device is asleep. However, it must be plugged in to AC power to ensure that it will wake up.
If you don’t have InstantGo, when you add a new alarm you’ll see a warning that alarms only work when your PC is awake.
If sound is muted, you won’t hear the alarm, but you’ll still get a notification.
