Help to replace on/off swith on dell - Dell Dimension 2400 PC Desktop


Answers :

Why do you think it needs replacing? What kind of Dell PC is it? Be advised that it's normal to have to hold it down for 4 seconds to turn it off. Jumping the pins on the motherboard should turn the computer on if the switch won't. If it will turn on by jumping the pins, then the switch may be bad, but it's not a very common part to fail. Replacing it should be pretty simple, if you have the replacement part.

More likely that the power supply is bad, or may be set to the wrong voltage (rear of the unit). (Desktop power supplies don't auto-switch for different voltages the way that laptop power supplies do.)
