Subject: Request for PMBus Firmware

Hi [Friend’s Name],

I need the correct PMBus firmware file for the Lenovo Legion Y530-15ICH (S/N: PF1J90SE).
Specifically, I am looking for the firmware for the MP2949A controller so I can flash it.

Could you please share the correct file with me?

Thanks a lot!

Best regards,

Hello everyone,

I am working on a Lenovo Y530 laptop, motherboard NM-B701 (REV 1.0).
The MP2949A controller IC on this board is dead and I have replaced it.
Now the new IC requires programming, otherwise there is no IREF voltage and no PWM output.

I have an EVKT-USBI2C-02 programmer ready, but I do not have the proper configuration file (.xml / .json) for the MP2949A used on NM-B701.

If anyone has the configuration dump or can share the proper MP2949A firmware/config file for Lenovo Y530 (NM-B701), it would be a huge help.

Thank you...
