The power button on most desktop computers is a momentary (push to make) switch. Two wires run from this switch to a small connector that pushes onto two pins on your motherboard. You can buy a replacement switch online from many good suppliers. However, if your computer case also has a reset switch, as many do, you can save yourself time, trouble and money by simply plugging the reset switch onto the pins where the power switch would normally fit. Use your reset button to turn the computer on and off. In an extreme case, it is possible to power on the computer by shorting across the two power switch pins with any metal object for a moment. However, this is not for the faint-hearted and if a mistake is made can potentially lead to serious damage to your system.

Why won't my computer screen turn on?

You either dont have it plugged in or your forgetting to use the power button. If they are on, then turn off the computer, take out the battery, and plug out the charger cord. Hold the power button down for about 30 seconds, then plug the charger into the computer. Then turn on the computer. It should work, this process resets something I can't remember, but it worked for mine.
