✔ Best Answer
I would absolutly love to know how you troubleshot that problem. In the 20 or so years I've been working on computers I have never thought to use a blow dryer on the switch.

The switch is just a momentary contact. Open up the case, follow the wires from the switch back to the connector on the motherboard. Remove the connector, then using a small screwdriver or other metal object, short the two pins together. If it turns on the computer, your switch is bad and will have to be replaced.

Sounds like a bad switch or a bad soldered contact to it. Applying heat expands things slightly so that it makes contact. I'd replace the switch.

How difficult can it be to solder a new switch in place? Pretty straightforward job. If you can't do it yourself take it into a repair shop and it shouldn't take them more than 10 minutes.

How do you think switches are connected to the motherboard? With wires. And how do you suppose the wires are connected to the switch?
