Hi,
please forgive me ignorance, but I am having a problem with an infra red control I am building to turn on my pc (from shut down, not to wake it up from suspend mode). My idea is to use a simple 9v infra red transmitter and a phototransistor, which activates the gate on a transistor, which in turn completes the i/o circuit for the pc button and turns it on. The switch works perfectly when I connect it to my circuit tester, but when I wire up the i/o button for the pc to my receiver, the pc turns off because the i/o button circuit is constantly made. I can provide a really basic schematic if it helps, but if anyone has tried this before or has any idea why this is not working I would be much obliged.
many thanks,
Chad
