This guide walks you through the steps to configure the required prerequisites to use Windows 10 Alarms & Clock correctly.

Prerequisite for Using Alarms in Windows 10

As I mentioned in the introduction, to ensure that Windows 10 Alarms work correctly, you need to sort out 2 prerequisites.

In the 2 sub-sections in this section, I will show you how to check that you set the correct Time Zone, Date and Time. You will also learn how to disable sleep in Windows 10.

Setting the correct time zone ensures that when you set an alarm, you receive notifications at the right time. Furthermore, disabling sleep ensures that you will receive alarm notifications. If your computer is configured to “sleep”, notifications will not show when the PC is “asleep”. If you are certain that your PC meets these 2 requirements, you can jump to the alarms section of this guide (link takes you to this section of the guide).

Set Time Zone, Date/Time Correctly

The first prerequisite to using alarms correctly is to check that your PC has the correct Time Zone. You also need to check that the Date and Time are set correctly.

  2. Next, scroll down to Time Zone, click the drop-down and select your correct Time Zone
  3. Finally, scroll back up to Set the date and time manually and click Change – set the correct time and date.

Disable Sleep Settings

For Windows 10 alarm notifications to display all the time, you need to disable sleep. Follow the steps below to stop Windows 10 from going to “sleep”.

  1. Right-click Start menu and select Settings.
  1. When Windows Settings open, click System -> Power & sleep. Finally, check that the Sleep section is set to Never on both while the laptop is on battery and while plugged into power.

Now that you have sorted out the 2 prerequisites, open alarms by searching alarms and opening the app.

In the subsequent sections, I have discussed the various things you can do with Alarms & Clocks in Windows 10.
