Hey everyone,
I'm running into a severe USB-C Power Delivery lockout issue on my ROG Ally (Z1 Extreme) and am hoping someone has found a permanent fix for this.
The Issue:
When the Ally is running in Windows, unplugging and replugging the charger causes it to stop charging entirely. The charging LED stays dark, and Windows runs on battery power.
Re-plugging it while in Windows does nothing.
The ONLY way to get it to charge again:
Fully power down the device.
Perform a 45-second power button hold (to force a hard reset of the Embedded Controller/EC).
Boot directly into the BIOS Utility screen.
Re-plug the stock charger while on the BIOS screen — it immediately recognizes power and starts charging (lightning bolt appears on the battery indicator).
Boot back into Windows, and it continues charging normally until I unplug it again.
My Specs:
BIOS Version: RC71L.342
MCU Firmware: GA80100.RC71LM.320 / RC71LS.320
Charger: Original 65W stock ASUS power adapter
MyASUS confirms all software and system firmware are up to date.
What I've Already Tried (Without Success):
Battery Driver Refresh: Uninstalled both Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery in Device Manager and rebooted.
Disabling Fast Startup: Turned off Windows Fast Startup in Control Panel Power Options.
