820-00840-A No Boot

[Toxic9996]

hello, I need guidance, I have an 820-00840-A, all the power lines are correct less on PM_EN_P1V8S0 where I have 3.2v and CPUVR_PWM1 0.40v, the start sequence is 20v,560ma-5 sec 650ma, 20 sec 390ma remains for all time, do you have any idea what the problem could be, thank you

Check to see if you have PP5V_S5.

Review the cases here - the one with 350mA current draw may be the same as yours.
