In some bios Setups you can set it up to have the computer turn on after the power to it has been removed (e.g. from a power failure) once the power has been restored again. If you can set it that way, you could connect the computer to an appliance timer on/off switch, and the computer will boot automatically when the power to it goes on. It has to be a grounded connection through the timer (three wire connection), so don't use a lamp timer switch (two wire connection). e.g. one meant to turn on the connection to a car block heater, or an in car heater in the winter.

Alright this link explains about the requirements for OnNow Device Power Management. To date current PCs has not addressed the requirements for reasons being:
1. No cooperation among system components.
2. Add-on components do not participate in power management
3. Current power management schemes fail for purposes of the OnNow goals.
4. Installing new devices is still not as easy as it must be.
Lastly but more problematic..
5. In general, applications assume that the computer is fully on at all times.
Perhaps the next generation of computers will be OnNow-compliant, functioning like our automatic coffee maker :-)
