PM_SLP_S4_L: 0 V

Follow: P5V_S3_EN ?

Does P5V_S3_EN missing mean that the enable is not on? vs something wrong with U7201

PM_SLP_S4_L is controlled by MCP.
Do you get 1.05V at L7770?
If not, change C7771.

BTW, check resistance to ground at L6995, in ohm scale.
Any value lower than 30K will point to bad MCP; 95% of "chance".
