Default [Q] My tablet doesn't turn on

I have a Vido N90 FHDRK. I didn't use it for about 20 days and yesterday I connected it with the charger. After 1min, I pushed the button to turn it on and the logo of waytec appeared. I closed the case immidiately without waying to open. This morning, I try to open it without a success. I've tried only power button, power button with volume button. Connected to charger and laptop. Nothing.

Edit: I tried it to another socket and seems that for a reason it hasn't charged at all. I wait for 5-10 minutes and when charged went up to 5% it opens
