I do not know if this is any help.
When I plugged into the socket wall, I have little sparks in the inside of the socket. It occurs from time to time.
The outlet has been sparking for 3 years?
This apparent defect and possibly extremely dangerous situation was first mentioned in post 8.
It seems to me, as we are now on post 126, and many posts ago, in fact shortly after post 8 you were going to contact the manger of the apartment block and inform him of the apparent defect in the electrical circuit. AND unless I have missed it I see no report of this being done and the result
Of course the defect may be in your laptop power lead that you are connecting to the power supply, or in the surge protector.
Either way, where ever the defect is, in my opinion until you have had the mains electrical supply checked, and declared in order, you cannot make any meaningful progress.
Indeed as my good colleague rshaffer61 has said, also many posts ago
EVEN if the electrical supply to your apartment is declared OK, the testing of the power lead and power supply for the computer is not something that can be really be done in an online situation.
YOU should I think be aware that your mains electrical supply can kill and I find it amazing that
For three years, sure. I think this happening before this all started
you can continue with a mains electrical supply socket apparently sparking.
I hope you do not find the post insulting, I can assure you that it is meant to highlight to you the extreme importance of ensuring your personal safety and indeed if it a multi- occupancy apartment block, the safety of all other occupants.
