Nintendo 3DS won't turn on.

Hey guys!

My name is Neto and I've been having a problem with my Nintendo 3DS for a few months now.

Some time ago I ran out of 3DS chargers, so I put off buying another one, but after a month I finally bought one. When I plugged it into my 3DS to charge, I left it charging for a long time, and then when I turned it on, it wouldn't turn on at all. The orange charging LED appears, but when I press the power button, it doesn't turn on. After a while I tried again, but now another situation has occurred. The console would turn on, the orange LED would light up, and after a while the LED would disappear. I had to unplug the charger and plug it back in to turn it on, but it always disappeared. Note: I tried with another battery from a friend of mine that was working normally, but without success.

I would appreciate any help.
