    Are you sure about your readings for PQ19 and RSMRST#?
    Check ALW_ON and SUS_ON. There should be 5V on coil PL9 before RSMRST# rises to its value of 3.3V.
    Your problem lies somewhere in ALW_ON and /or SUS_ON

      Black probe to ground, red probe on the coil's pin. PL9: 5.1V

        Your post#24 measurement tells us that 5V is not present on PL9.
        If you give us wrong feedback,the entire disgnosis goes wrong.
        What about SUS_ON?

          Yeah, the method was totally wrong because i didn't know how to use the multimeter. Unfortunately I will not be home for the next 4 or 6 hours so don't wait for me. Thank you!

            PL11: 3.3V
            PL9: 5.1V
            PL5: 1V
            PL8: 1.5V
            PL6: 0.88V
            PL4: 0.8V
            PL3: 0.8V
            PL10: 1.8V and dropping, cant get a consistent reading from this inductor
            PL7: 1.05V
            SUS_ON: 3.3V
            Also the CPU gets super hot without the heatsink install (Is that a sign of a short)
