HP elibook x360 G3 - usb-c Issue after Bios Update ("HP Firmware Pack (Q90)")

HP Recommended
HP elibook x360 G3
Microsoft Windows 10 (64-bit)



Since the update of the bios named "HP Firmware Pack (Q90)", we cannot charge anymore with the USB-C (only possible with these ports !!!) or use the docking station thunderbolt 3 with the Display port.

If we check in the "device manager", we see that the USBSCI Connector manager is in power failure.

We try to downgrade the Bios without success, the Laptop refused to downgrade the USB-C firwmware and after a lot of tentatives, our battery has less than 50%, so nothing is possible now.


Great Job HP to do not test correctly you Bios before releasing for the Public because now, I have 2 Laptop  down.

I can also confirm that i have no issue with the same laptop with the previous Bios (July 2018).

You will need to contact HP support directly and inquire about getting the SLIC file for the BIOS that you need.
