    [help]820-00165 TOTALLY DEAD! NO LED LIGHT CHARGER

    've found in diode mode a super low value on pp3v42_g3h...removing l7095 and l7090, i've injected voltage on the line and found that u5000 become hot (3v 0,0100 amp)
    replaced u5000 with a brand new one now i have
    PPBUS_G3H=8.18
    3V42_G3H=3.42
    3V3_S5 3,3
    no voltage for PP3V3_SUS (no shorts
    on u8020 i have 0v on P3V3SUS_EN no shorts
    0v on R1464 no shorts

    SMC_ADAPTER_EN, 0v
    PM_BATLOW_L, 3,3
    PCH_DSWVRMEN, 0v
    PM_DSW_PWRGD 0,9v

          PPBUS_G3H=8.18 --> should be 8.6V if SMC is running

          You can only use SMC's from donor boards. If it's blank and never been programmed that will not work. You can use a SMC from 820-3437 board and reprogram it for a 820-00165 board using Muerto's SMC flashing tool. Board will still boot, just have issues with audio IIRC until you use the tool.

                Shorted PCH by the looks. Put it in your donor pile.
