My power supply switch (on the CPU) is not working properly and I have to keep adjusting it to turn the PC on. Is there a way to keep it on "Standby" after disconnecting it from the ISP and turning it on whenever I want to without having to use the power switch (hitting any key on the keybard). I tried it but I heard the fan inside the CPU runninng. Is it normal, in "Standby" mode?
