Detailed description:


I have set up a new ASUS Zenbook 14 UX425J. After all Updates from Windows Update I installed also all Updates from the Driver Site. Now I can't charge it anymore and both USB-C ports a dead - is it possible that the Power Delivery FW upgrade V1.0 is not compatible? Why would it install then?

In Device-Manager the USDB-Device USM-USCI ACPI-Device is not functioning and the charing LED is of. I tested the charger on another device (it's working) and another charger without luck.

I reseted the bios to defaults and did a reset by pressing the button more than 50 sek.

PS: I have just 35% battery left. This device can only be charged via USB-C

Can not charge Zenbook 14 UX425J - Maybe Power Delivery FW upgrade?

I have a same problem with USB-C on UX425JA.
Did user PJD solve it?
I need "old" firmware too.

Hi there,
There is no new PD firmware for JA, but it can not use EA firmware either.
So if you have installed the EA firmware, please send the device back to the service center to install the JA one back.
I'm sorry that it can not be done by end user.
Thank you.
