Even though my switch board socket as well as my charging laptop adapter supports 3 pin Earthing/Grounding.
Whenever I begin to hot boot my laptop either from Shut-Down-state/Stand-By/Sleep/Hibernate Mode while leaving behind my charger adapter connecting to power socket before/after my laptop battery gets completely backed up with charge. Suddenly Grounding/Earthing(⏚) Symbol appears in my Electricity Meter indicator.
But the vice versa is not true. i.e., whenever I completely switch Shut-Down/Stand-By/Sleep/Hibernate Mode, leaving behind my charger adapter connecting to power socket Grounding/Earthing(⏚) Symbol disappears in my Electricity Meter indicator
Couple of days when an head phone is connected, even though I could hear the audio from my ear phone. But audio from the laptop doesn't get automatically muted after connecting the head phone.
What is the reason behind this? How do I need to solve this?
It appears you have a ground loop caused by another device besides your laptop and its OEM charging adapter. Can you draw a picture of your set up, scan it, and edit your question? – John – 2020-01-26T13:56:52.467
