SOC SIGNAL PROBLEM OF HP 840 G1 (PART 1) | Latest Generation Laptop Chip level Training

Latest Generation #SOC SIGNAL PROBLEM OF HP 840 G1 Laptop problem and solution.

Laptop #Motherboard like 6th, 7th, and 8th generation can only be solved with proper #Logic and understanding of the power rail flow in the SOC logic.

In this case study, we will discuss the failure of the HP 840 G1 laptop motherboard problem with S4 state enabling signal generating PWM pulses instead of the 3.3V voltage supply.

For solving the above case you should understand the proper working of the states and the motherboard condition in S3, S4, S5, S0, and G3 states.

The above sleep states are enabling inputs that generate the required state voltages and laptop motherboard is switched properly from the ALW (Always) state to SUS (Suspend) state and then to the RUN (Full-on state).
