Light on power cord stays amber, even after resetting SMC
Last December, I asked this question:
My MacBook Pro's battery is fully charged, but the light on the cord remains amber … for days and days. Any idea why?
And was referred to this doc:
How to reset the SMC of your Mac <https://support.apple.com/en-us/HT201295>.
This solution worked for a couple of weeks, then the problem returned. Resetting the SMC a second time did not resolve the issue.
Any other suggestions? How serious could this problem be?
Thank you.
