    Help Understanding The Different Power Supply Voltages in Schematic

    Hi everyone,
    this is my first post, I need help understanding the difference in power supply voltages in my hp laptop motherboard. I have the diagram of a driver ic which controls 2 mosfet. and I'm trying to find out why I don't have 3.3v on source of PQ55, also I need to understand the difference between all these voltages, why I have 3.3v and +3VAWL. If someone can explain the difference in the following voltages and what they mean and when are they present. This is for an HP Pavilion g6 laptop motherboard
    +3V, +3VSUS, +3VS5, +VAD, ACIN, +VAD_1, +12ALW, MAIND, +VIN_VCC_CORE, +VIN, +VCC_CORE
    see attached image file

      Or at the very least write motherboard model number or full laptop model number — we can't guess what you have on your desk…

        I couldn't find how to edit the original post, hope everyone can see this info. This is motherboard part number
        DA0R53MB6E1 REV E R53

        and this is laptop model:
        HP Pavilion g6-2321dx

        I have not search this forum for schematics, but this is the one I'm using for repairs.
