Tool/software:

Hi Raymond,

Item : eGFX_AMD and eGFX_NVIDIA
Detail : SUT will shows yellow bang when power on the system.

refer to below from Raymond.

eGFX: Looks like there be some correlation between the PDO power and their external GPU having issues.

I’ve attached PD logs captured for each of these issues. I recommend following up on e2e for each of these issues with the attached logs for further debug.

Hi Marty ,

Apologies for the delay.

Thanks for sharing the logs.

Will higher PDO cause an issue in the system? Error logs have 20V PDO.

Please share PJT filed used as well.

Thanks ,

Hi Marty ,

Please confirm if EC is over-writing the settings over I2C lines in the failed case.

Will higher PDO cause an issue in the system?

Thanks ,
