Early MB-A Battery has stopped charging

Question

G'day All - I have an early MBA that has just stopped charging the battery.
The adapter still powers the computer and shows the green LED, but it never goes amber now showing the battery being charged. I have changed adapters, reset the SMC and PRAM - all without change.
If take out the adapter, the computer instantly dies. On restart after sudden death, with the adapter plugged in of course - only way to restart - the computer clock has lost all track of date/time. Interestingly, if I shutdown/restart with the adapter remaining connected throughout, it doesnt lose the date and time. Bizarre!
CoconutBattery says the battery is in good shape but not charging. It shows 17% and that does not change - I thought it might slowly reduce with some kind of trickle discharge
AHT doesn't run on this computer.
Feels like a hardware failure to me - any ideas please?
Thanks
