I don't know what happened but when i plug in my AC adapter into my laptop the light that indicates that the battery is charging is not showing. When i power on my computer, it powers up normally from only AC adapter cord, only battery, and both but the battery isn't getting charged. The connection between the AC adapter and the motherboard is fine as it powers up with the battery taken out and the connection between the battery and the motherboard is fine as it powers up with the battery in and the AC adapter out but the light isn't there to indicate the battery is being charged. when i log into my account, the icon at the bottom (when plugged in) says that its fully charged but when I take it out it says its less than 100% charged. when i leave the battery and AC adapter in for an hour, the battery charge hasn't changed and i fear that the connection between the AC adapter and the battery has shorted out or something. I have taken my laptop apart and there isn't any visible problems that I can see as the wire that connects the AC adapter is fine and has no problems and the prongs that the battery plugs into the motherboard is in working condition. I think its a short in the motherboard but i'm not sure. What is your thought on this problem and please tell me anything that could have caused this or how to solve this problem.
