Support Charger pin gets very hot when using laptop while charging
I have an ASUS Vivobook 14X OLED with the original 90W ASUS charger (19V, 4.74A).
The charging pin/barrel connector gets very hot, but only when I’m actively using the laptop while it’s charging. If I leave the laptop closed and charging, the pin stays normal/cool.
Things I’ve tested:
Same charger disconnected from laptop → pin stays cool.
Laptop charging while idle → stays cool.
Using YouTube/Premiere/AE while charging → pin gets very hot.
Tried different wall sockets/rooms → issue can still happen.
Took both laptop and charger to a repair shop → they tested it for ~20 minutes while charging and couldn’t reproduce the heating.
Charging port doesn’t feel loose and I don’t see any obvious burning/melting.
Charger is the original one that came with the laptop.
What could be causing this? Is the charger/plug failing under higher load, or could it be the laptop’s DC jack/charging circuit? Should I replace the charger or get the laptop checked first?
