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.

0002
| Hex | Name | Description | Type | Repair Guide |
|---|---|---|---|---|
| 0x02 | ERROR_V_CPUCORE | VREG_CPU_PWRGD negated unexpectedly | EC_FATAL | 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 | Type | Repair Guide |
|---|---|---|---|---|
| 0x03 | ERROR_V_GPUCORE | VREG_GPU_PWRGD negated unexpectedly | EC_FATAL | 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 | Type | Repair Guide |
|---|---|---|---|---|
| 0x04 | ERROR_NO_ANA | ANA/HANA is not responding to reads or writes | EC_FATAL | 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.
