It was healthy battery before the message appeared. Yes it has only 50% health left comparing to report done in year 2016 before upgrade to Windows 10. What is going on?
There was a issue with AC cable so it was switching charge on/off multiple times a day and seems to have added lot to battery cycle count and then it stopped charge at all and started to discharge from 100%. Now the charger and cable is replaced with original OEM but battery is still not charging. It was healthy battery and even did calibration before it was locked so it had still 50% health left. Seems there is some internal counter in battery which locks it when counter reaches hundreds of charges even that it still is normal healthy battery.
Another laptop(NP900X4D) experiencing similar issue -
Seems they are blocked by expiration date. Some kind of timebomb. For this laptop there is still 66% capacity left but shows "plugged in not charging, 73%"
