If the machine works on A/C but the battery does not charge I think it is unlikely that the dock will help.  My experience has been that this problem is usually (not always) a little fuse on the motherboard near the battery connector

I actually load it but it shuts down and I get a message saying that the AC is not the right one, but in reality it is. Then the load will only turn off not lit

Tell me about the power supply?  Wattage?  Do you have a way to test the resistance between the signal pin in the tip and the outside metal face of the tip?

Yes, I think the problem is in the charger, buy a new one to identify. When the ship arrives I will be in charge of commenting on what happens to be a future help.

Yes, what happens is that I damaged the original charger and bought one round tip and a round to square adapter. This does not work !!! therefore buy one square tip and go. Thank you very much for your prompt response. Long live the free community!
