Got the Acer torn to bits.
Doesn't look promising, to find the charging circuit fault.
I can't see anything that looks like a small surface mount chip fuse, as was shown in a picture on one of the posts I found on the internet.
I can't even trace the circuit from the notebook power jack to the battery terminals, because the traces are not visible. :-( Probably a dual layer circuit board.
A new circuit board seems to be around over $100 USD on Ebay, so that is not an option.
I found a circuit diagram which is for the motherboard that I have. Not sure though, since it appears to show more terminals for the battery connector, than what is actually there.
None of the components have a value shown, so that is not much help, either.
Looks like I will just button the notebook back up and run it off hydro from now on, :-(
