How to Add or Remove "Allow wake timers" in Power Options in Windows


information   Information
The "Allow wake timers" power option setting enables or disables Windows to automatically wake your computer from sleep on a timer for scheduled tasks and other programs.

This tutorial will show you how to add or remove the "Allow wake timers" setting under Sleep in Power Options for all users in Vista, Windows 7, and Windows 8.

You must be signed in as an administrator to be able to do the steps in this tutorial.

Note   Note
This could be handy if you wanted to set this how you wanted, then remove the setting to prevent other users from being able to change it in Power Options.


Windows 8 automatically disables the Allow wake timers option for AC power (Plugged in) and Battery power when no ACPI Wake Alarm device is detected on the computer, on all default power plans, for mobile computers.
