Power Button Broken phone will not turn on

My Galaxy S4 has a broken power button and I cannot get it to turn on. I have tried literally everything, all the tricks like plugging it in and taking the battery out really fast and all the other tricks I have found online. The furthest I have got is a black screen with white letters that says Samsung Galaxy, looks like it is about to power on, but then it turns off after a second or so. I have also tried plugging it in to a computer. Please let me know if there is anything else I can try to get this device on cause I am very desperate!
