Spectre x360 13-4103DX Laptop won't charge or turn on; any ideas?
I've already replaced the charging port to no avail. There does not appear to be any water damage.
You obviously do not get a charge light or any response when plugging in the machine? It will be the mainboard that needs to be replaced.
Potentially the battery but I assume you have tried plugging in the Charger without the battery connected?
Try minimum config, which means unplug all removable components from mainboard (remove LCD cables, KB cable, KB backlight, wifi card if removable, battery etc.) and leave only charging port and if separate the power button ( some laptops have separate Pwr button board) and see if you get a response from charger. If you do add each component one by one until symptom returns. If still no response it will likely be a motherboard that needs to be replaced.
