    hp probook 430 g4 - quanta - da0x81mb6e0

    - problem: no vccgt nor vcc_core

    - recovered missing power_good 3-rails by replacing pu14
    - replaced pu2
    => no gate-voltages
    - mosfets are intact
    - every other important rail present: dead cpu/broken solder balls under it?

    - replaced kbc and flashed bios with clean me

    - when plugging in ac-adaptor 4 orange lights are flashing while white stays steady

    thanks for more input!

          SVID_ALERT# is Most likely dead CPU.

          Edit: i Don't know exactly the purpose of +VCCSFR, but is +VCCST present?

          Edit2: Just saw both rails are The Same.

            yeah, that's why i thought... dead cpu, tho. a shame this model is relatively rare with i7 cpu...

            - vccsfr/vccst is present: 1.00 V

            and thanks
