If your phone doesn't have the power button anymore or the power button fell off and you lost it, go and find a paperclip or the thing you use to open your phone to insert Sim cards. Then try to feel for a button. Get the tip of the paperclip or thin but hard object your using and give it a Lil old push. If it doesn't turn on try charging it and doing the same thing but holding it down until it powers back on. That's the trick I'm using to write this guide on my broken phone as we speak! And BTW, if there is no button, try and tinker with the silver part in the middle of the hole where the power button was with the paperclip and see if it reacts, then use that point as a guide to open up your phone
