MacBook Air Battery Charging stuck at 1%

Hi, I've got a early 2105 MacBook Air 13". I am running Catalina 10.15. I installed a new after market battery after the original gave up. Everything has been running fine for several months (maybe 6?). Suddenly it won't charge and says 1%. (no light at all on the power plug) After reading other/older posts here is what I have tried:

Rebooting computer (Several times)
Inspecting and cleaning the port.
Reseting SMC (several times)
Reseting Pram (several times)
I've tried 4 different power adapters, all the same result.
Installed and run Coconut Battery with this result:

Is there anything else to try? Is it possible (with the above readings) that my battery is no good and I should try a new one?

Thanks so much!

MacBook Air

There is another component part within the charging circuit

that may be at fault; this would require a service interval to

test, diagnose, and replace.

An item generally known as combo I/O board w/ power, data,

and manages power from the AC adapter to provide charge

on demand. Then when charged, eases off; while Mac is still

attached to charger and manages battery charge.

So it's possible and likely, this circuit board has partial defect;

that allows some aspect of power to flow, but fails otherwise.

With this in repair, the mac may also need new battery.

Another part that can sometimes cause issue, when charger

has issue with its connector (magsafe? can have stuck pins

or otherwise cannot get power through port.)

One of the options depending on locality, allows user to return

the Mac to Apple repair in box they send out for this purpose.

Some newer models of portable Mac no longer use 'magsafe' adapters; however

ideas on power and adapters can be found in with key words in search.
