My tablet won't turn on, the battery died and it hasn't turned on sinc

I left it charging to see if that was the problem; other times it had turned on by itself, but this time it wouldn't turn on at all. There were times when I left it charging and tried to turn it on, and it would just show the logo and then turn off again. After that, it wouldn't turn on at all, and I couldn't even factory reset it.

What can I do in this case?
