It was working normally. I had issue with the laptop casing, which was a little low sturdy and some of its screws pulled up the embedded nuts out of the box. These nuts were near the screen hinges. I had to cut a disfigured tin connector to fix those nuts back in socket with instant paste so as to fix the casing to the machine.
Since then I am getting these warning messages. But the laptop is running normally and I do not find any abnormal heating of the machine. Don't know whether these warnings are real or some bug anywhere.
With what you did it's a bit hard to figure out what caused the issues but I would guess your connectors are touching something causing a bad read out of the fan connection. Is the fan actually working OK?
