Tip #36: Scheduled Boot Up From Stand By in Windows XP
To wake from Stand By automatically, we’ll be using a free utility called, appropriately enough, WakeUpOnStandBy. This is a small utility which allows you to specify the time you’d like your machine to “Wake Up”, as well as also giving you the option run an application immediately following the return from Stand By. WakeUpOnStandBy can be downloaded from here.
After you have downloaded the utility, launch the program and you’ll be presented with a screen similar to the following:

You’ll need to specify the date and time you’d like to wake the machine up, and provide an optional application and its parameters you’d like to run. Then click on Start, and finally click on the Switch to Tray button.
Now if you select Stand By instead of Shutdown when you power off your machine at night, it should be waiting ready to go when you arrive back in the morning.
