Is there a Windows-tool that is able to automatically revive the computer from standby / sleep mode at a given time?

Tool for automatic start from standby / sleep mode at a given time

WakeupOnStandBy will do this for you:

  • Can restore almost every Windows-based operating system from a Stand-by mode (and some from hibernation) that support ACPI (Advanced Configuration and Power Interface) (For support check computer's BIOS as well as Control Panel -> Power Options);
  • Can run a file or open a web page at a predetermined time after a wake-up event, during normal operation, or before performing power operation;
  • Can send system back to Stand-by mode (hibernate it, shut it down, or log off user) after a certain time interval;
  • Can detect if Stand-by mode (or hibernation) is supported by your system;
  • Can turn the monitor on and hold off screen-saver during the waiting time;
  • Can repair local area network and high-speed Internet connection upon waking up from a suspended state;
  • Can send system into Stand-by mode or hibernate it with more options than available through Operating System;
  • Can be incorporated into an in-car (entertainment) PC system to speed up booting time & save battery [more here];
  • Can be run from the Windows Command Line without user interaction;
  • Can be saved as a batch file for later use.
  • Do you know of an alternative that works for Windows 7? That one does not, at least not on my Dell Inspiron 9400. Feb 28, 2010 at 23:36
  • @Jonas Elfström - i think not Windows 7 is the problem but rather the ACPI settings/capabilities of your Dell.

  • It worked after I switched on Allow wake timers in Advanced power settings. Thanks! Feb 28, 2010 at 23:47

  • It worked last night and then I set it to start at 06:15 this morning but it had not. I started it manually and WSOB wasn't even running anymore. Does not seem to be very stable. Mar 1, 2010 at 9:01

I use a scheduled task, with the wake from stand by option checked.


Scheduled Task Options

  • Could you please elaborate on how you do that ?
