Scheduled Task is set to "Wake the computer to run this task" but it doesn't if the computer's in Sleep Mode.

Cause

By default, the ability to wake the system from sleep for a timed event is disabled on Windows 7-based mobile PCs. Programmed timed events do not wake the system regardless of whether the mobile PC is on AC or on battery power. However, you can change the

Power Options

settings to enable the wake timers.

Resolution

To change this behavior, follow these steps.

Note

Your mobile PC may wake up for tasks under some unexpected circumstance. For example, your mobile PC may wake up when it is in a bag or in a thermally constrained environment. We recommend that you evaluate the issues that may occur before you change the settings.
