Acer Aspire One 14" Z1402-343F

I have situations with my laptop.

1) I left it sleep if im not mistaken and after few hours, tried to turn it on again, but couldn't. So i think it runs out of battery power. So I charged, and yes the light comes up and its totally red, hence no power. Then I put the power supply on and tried to turn it on, i couldnt. Black screen all the way. Tried again by pressing the power button off for few seconds and then turned them on again, same thing happened, it turns on but black screen. So I let it charged for a while. Then, I tried to turn it on again after 30 mins or so, same thing. Its on but black screen. I take off the power supply, tried to turn it on again, its on but shuts off after few seconds. Then I tried to put the power supply again, but the light indicator for the charging process is not coming up. It adds up to the problem. But I tried to turned it on with power supply, it was on but black screen. When I took off the power supply, its on but then shuts off few seconds after. I let it charge now, but no lights indication that it is charged or so. So i dont know. any solutions to this?
