Hello!
I have an OEM charger for my laptop (Model number:DA130PE1-00), and after 5 years of use there are signs of wear right below the tip of the DC pin.
There are three exposed wires - green, white and black. The insulation around the white and black wires has been damaged (apparently from twisting) and the wiring within is now exposed and frayed, as can be seen in the attached picture. I just noticed sparking from where those wires are exposed while the charger was plugged in and connected to my computer, and I have two main concerns;

1) could this sparking damage the motherboard or any other components of the laptop?
2) would it be possible to safely repair the insulation with some electrical tape? Or would this fault still pose a risk to the laptop?
As an aside, this morning I had to remove the battery from my laptop because it had significantly expanded - could this wiring issue have contributed to that swelling?
If there's any more information I can provide I'd be happy to do so, and thanks for taking the time to look at this!
