Can we use the same mechanism like in digital alarm clock?
i.e wen the preset time comes it sends a small current to the buzzer which make the noise.The same thing with a little diff can be applied here.
That is wen the preset time comes the circuit is complete(the two wires of the power button is shorted) for a second or two and the computer boots up.
If it is possible please send me the circuit diagram.I can get an old alarm clock and we can make necessary changes for this purpose.
Please ...Please help me.......

Yeah this will do the trick u can make use of that voltage coming to the buzzer, u only need a small amplifier to increase the current to drive a relay.This will make a cheap timer clock with good accuracy.
