I would try a new battery, just because its so cheap to try,
and because you can see a bad battery produce symptoms
like you have, even tho its not very likely to be the problem.

Looks pretty clear that the motherboard has failed
and it isnt necessarily that viable to replace it, it may
well be a good time to go for a new system now.
