My iPhone won't turn on after I plugged it it?

My battery was half full when I plugged it while I was in the car. When I plugged it in it shut down and won't turn on. I tried connecting it to my laptop and several different cords but it still won't turn on. Any ideas as to what happened?

Short circuit? O.o

Just press the Power Button(Lock) and the Home Button until the Apple logo come out. It make take up to 10 sec, but if after 10 sec you haven't receive any response leave till 30 - 60 seconds!

Good Luck, Let us know if you were able to fix it!

Hold all the buttons down at one time and hold it
