My Acer Iconia won't turn back on

Timothé

When I try to open it nothing happen but when i try to charge it a little red light open and then flash but the tablet still won't turn on without any sign of it even opening (like the Acer logo when you open it)
I tried:
using a different charger and let it charge 
pull out the charger USB press power for 10 seconds and then put back the charger and press the power for 20 seconds 
try to press the reset button with a pencil pressed it for 5 seconds and nothing happened 
try to let it charge a whole night and nothing happened 

the only thing I'm thinking right now is to bring it to a technician cause it was definitely working before my dad didn't use it for mouths so he gave it to me so I can try to draw on it.

if you have any idea how I could fix this please take the time to tell me and thank you if you do.

 Change the battery as its gone and needs replacing. Try that first.
