There is that USB Killer device. Tell more but no fuses in all the laptops I've worked on.
Do any lights come on? How do you know the charger is good?
Apparently shorted out power thru USB port on ASUS Q301L, with next slot earplug jack. Was on AC power so batt still charged. BUt now LED, is theira power or mother board fuse? Only 3 easy years old.
