SensoAdapt Skin Contact Failure
Error E01 indicates a SensoAdapt optical skin contact sensor failure. The dual optical photodiodes or UV-IR colorimeter sensors flanking the light window failed to verify continuous full flush contact or safe pigmentation threshold, inhibiting high-voltage xenon flash capacitor discharge.
Xenon Capacitor Charging Timeout
The main microcontroller triggered an E2 safety lockout due to the dual-lamp high-voltage photoflash capacitor failing to reach target operational potential (typically 380V-420V DC) within the maximum allowed charging window (exceeding 1200ms).
Bottom Ring Flashing Red
The bottom indicator ring flashes red when the onboard NTC thermistor detects an over-temperature condition (typically exceeding 105°C/221°F) due to restricted intake airflow, lint accumulation around the micro-mesh filter, or internal motor thermal throttling.
PCIe Bus WHEA 17 Crash
WHEA-Logger Event 17 indicates a corrected or uncorrected PCI Express root port error originating from the AMD Ryzen Z1 Extreme APU interconnect. Under 25W Turbo load, transient power draw induces VDDCR_SOC or PCIe PHY voltage sag alongside thermal expansion on the M.2/Wi-Fi/SoC bus lines, destabilizing signal integrity and forcing a Windows WHEA_UNCORRECTABLE_ERROR (0x124) crash.
SensoAdapt Sensor Flash Lockout
The top LED indicator flashes red when the dual SensoAdapt skin tone optical sensors detect insufficient skin contact, incompatible skin pigmentation (Fitzpatrick type VI lockout), or an optical path obstruction over the photodiodes, triggering a firmware safety discharge inhibit.
Legion Go 5 Amber Blinks
Five amber blinks on the Legion Go power indicator signal an Embedded Controller (EC) emergency thermal trip (PROCHOT# asserted) or a power rail fault triggering an Over-Temperature Protection (OTP) latch shutdown on the primary APU/VRM voltage rails.
Sapphire Cooling Overheat Shutdown
The E2 fault triggers when the internal NTC thermistor detects an over-temperature state exceeding 55°C at the thermoelectric peltier assembly or sapphire contact window, forcing an emergency shutdown to prevent thermal skin burns and protect the Xenon flash tube.
VibraRise Mop Actuator Jammed
Error 10 triggers when the robot controller detects an overcurrent trip or stroke timeout on the VibraRise mop carriage lift actuator circuit. When transitioning between hard surfaces and carpet, the microcontroller energizes the mop lift motor via an H-bridge driver while polling limit switches or optical position interrupters. If current exceeds safe operational limits (typically >450mA peak) or if stroke limits fail to transition within 3.5 seconds due to mechanical binding, broken gearing, or sensor misalignment, the robot halts to prevent motor thermal runaway.
LDS Sensor Jammed or Obstructed
The Laser Distance Sensor (LDS) turret failed to spin or the optical triangulation receiver timed out during initialization. The MCU monitors the LDS motor's optical encoder/hall-feedback RPM and current draw; if the turret does not reach approximately 300 RPM (5 Hz) within 3 seconds, a stall protection fault is asserted.
Xenon HV Capacitor Charge Timeout
The main microcontroller's internal safety timer tripped after the flyback boost converter failed to charge the high-voltage photoflash capacitor to its nominal 380V-420V threshold within the programmed charging window (typically <1.5s), triggering an emergency shutdown indicated by solid or flashing red LEDs.
