Zephyrus G15 USB-C malfunctioning

[Mohsan_Niaz]

Hi everyone,

I own an ASUS Zephyrus G15 (GA503RM). The USB-C ports are not working and Windows is showing a code-43 error for UCM-UCSI ACPI in the Device Manager. Has anyone experienced this error before? If it is a hardware-related issue on the motherboard? Can anyone guide which component needs to be replaced?

Hi @Mohsan_Niaz ,

Please try updating the BIOS to the latest version 318. After that, uninstall the UCM-UCSI ACPI and Type-C related drivers in Device Manager, then restart your computer and let Windows automatically reinstall the drivers to see if the issue improves. Thank you.

Hi Anbby,

Thank you for your reply. I had followed the procedure, but it didn't work. So I followed the solution on the following URL on Reddit.

I uninstalled the UCM UCSI ACPI driver and then opened the laptop. I disconnected the battery from the motherboard. I pressed the turn-on key for 60 seconds. Then connected the battery again. I charged the laptop and turned it on. Again reinstalled the UCM UCSI ACPI driver, and the problem was gone.
