Reference U91

Thank you for your collaboration in this matter.

1. The I2C stage with FRU 1 on the motherboard involve U91 component and J15 connector, so continuity between signals I2C was checked but no issues where detected.

1. The J15 and U91 component was checked on X-Ray but no solder issue was detected on component’s spheres.

1. No passives components issues nor solder defects related to the stage.

1. Due to the passive components, PCB issues and solder defects were discarded it means that the U91 component has an electrical damaged and I2C communication between FRU 1 and U91 is not working correctly.

The U91 was send to replaced and the unit will be tested in order to completed its RMA process
