[AC Question]

Hello, so I was just going to search for something on the internet through my phone and when I pressed the home key expecting it to turn on, it didn't. I was playing whole day on my laptop and I only used the phone a bit on the morning and so I didn't do anything. Tried getting out the battery, SIM card, SD card etc and to restart but nothing. Even plugging it in to recharge doesn't works, doesn't even starts up. I don't know what to do, I don't really understand how to fix these kind of problems on my phone but I kinda think that resetting my phone would work because same thing happened before while I was playing and people from the shop reset all and it worked. Hope someone helps me.
