my phone is not switching on! T^T

I have a samsung galaxy grand prime (SM-G531H) and i was using it normally then i guess it switched off due to battery so i went to charge it after a while i tried to power it on but it didnt work at all i searched youtube googled and even tried the button combination like hard rest soft reset but none of those work the only thing which i can see on my phone is the battery image when its charging and switched off but when i try to turn it on nothing happened i tried almost everything but none work so iam hoping if anyone could help me plssssss that would make me really grateful
(ps i also tried when it was at 100%) but still no use
