Built-in controller / MCU failure with short near MCU
MCU / left joystick board controller electronics
Source-linkedVerify source — Reddit postWhile playing, ROG Ally built-in controls suddenly died—no buttons, sticks, RGB, or power LED (charge LED still works). Touchscreen and volume still work across Windows and SteamOS; Armoury Crate shows an embedded-controller error and MCU updater fails. Owner later found a hot/shorted area next to the MCU chip on the left joystick board after probing voltages.
