From my charging cable, the battery is defective so I can only turn on my laptop with charging cable since recently, this is synonymous net more. As soon as I connect my charging cable to the laptop, there's a smell, so I screwed on my laptop. The solder joints of the power supply socket and the outside of the motherboard is burned. Power supply jack looks quite normal I can't see anything because of a short circuit caused there, because I have no soldering iron, I can't take out the power supply socket to me to look at the more accurate. Otherwise, there are no burns the whole motherboard looks normal. I do not use an original charging cable as soon as I connect my charging cable to the laptop, the LED of the charging cable weakens but it still lights up. My question is what do you think it is because of the charging cable or the power adapter socket?
I also have no gauges or anything else to test my cable.
Otherwise, if the calculator works and does not get overly hot, it might be enough to re-solder the jack.
It is quite possible that the contacts have been solved by frequent use. As a result, there's heat from the increased resistance due to the current.
After all, 2-4A should flow there, that must be very warm, if the solder joint is broken.
