Hi,

 

I've noticed recently that charging LED becomes to blink when battery is fully charged. I did hardware reset pressing power button, updated BIOS firmware, but nothing helped. All tests from diagnostic menu for related to the battery, etc. passed successfully.  When power plug disconnected, battery uncharges and charges to 100 % without any problem. Apparently it happened after Windows 10 update to version 1909

 

Thank you for any help.

My guess would be that some connection in either your charger or an internal power cable is arcing from somewhere. Basically a short to ground somewhere within the laptop. Could be a resistor or something so I suggest you take it to someone who can take a look because the end result might be a burnt charging socket that connects to your motherboard. Have them run a few amps through the motherboard and just touch around to motherboard to see if anything is hot enough to burn your finger, and you will find your culprit. In short, it's most likely a hardware problem and not a software problem.

Thank you for your reply.

 

Seems you are right. I observed very strange result of battery test, even though it passed successfully: when laptop runs on battery Primary_Current is 65032mA and it is unreal
