SMC Errors

These errors are generated by the System Management Controller.

0001

ANA_V12P0_PWRGD is driven high by the ANA (later HANA) as long as the V_12P0 rail is within tolerance. If V_12P0 ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter EC_FATAL and the 0001 code to be displayed on the front panel.

Hex Name Description Repair Guide
0x01 ERROR_V_12P0 ANA_V12P0_PWRGD negated unexpectedly 0001

0002

Hex Name Description Repair Guide
0x02 ERROR_V_CPUCORE VREG_CPU_PWRGD negated unexpectedly 0002

VREG_CPU_PWRGD is driven high by the CPU power controller as long as the V_CPUCORE rail is within tolerance. If V_CPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter EC_FATAL and the 0002 code to be displayed on the front panel.

0003

Hex Name Description Repair Guide
0x03 ERROR_V_GPUCORE VREG_GPU_PWRGD negated unexpectedly 0003

VREG_GPU_PWRGD is driven high by the GPU power controller as long as the V_GPUCORE rail is within tolerance. If V_GPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter EC_FATAL and the 0003 code to be displayed on the front panel.

0010

Hex Name Description Repair Guide
0x04 ERROR_NO_ANA ANA/HANA is not responding to reads or writes 0010

The SMC communicates with the ANA/HANA via the SMBus. If communication is lost, the SMC enters EC_FATAL and the 0010 code is displayed on the front panel.
