galaxy s3 screen wont turn on, then after taking battery out, phone will not turn on

[AC Question]

after taking my phone off the charger, I see that it is on because the little blue light is blinking like I have a message, but when I push the side button the screen wont turn on. I take the battery out thinking I can just restart it. the phone will not turn on at all now.

Welcome to Android Central! Take the battery out, lay it flat on a table, and try to spin it. If it spins freely, it's bulging in the middle, which suggests a failing battery. Try a new battery.

Also, have you tried pressing and holding the Power button down for 15 seconds or so?
