My power button is broken and I can't turn on my laptop I have a gateway laptop and all I want to know if their is any way to turn it on other than the power button
No. You need to replace the button with the same or a 'normally open momentary contact button' that is not too easily pressed in error. The original button (under the physical plastic button you actually press) would be the best to use though it is probably soldered onto the motherboard so unless you have serious soldering experience on circuit boards, you should see a pro for this. You have to be a little bit crazy to keep you from going insane.
