    [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.

                    Dead Dell Latitude 5420 not receiving 20 volts from USB-C charger
                    by BTubbs200
                    Hello,

                    Dell Latitude 5420 P137G
                    Board: LA-K491P REV A01

                    I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

                    Board seems to have no shorts, all power rails are fine and show high resistance.

                    When charger is plugged in, voltage is present in 3.3V rail but absent in others....

                    Lenovo 14ALC6 - NMD521 - No power, totally dead.
                    by Mike Russell
                    Machine won't power on, no power led, no fan spin, completely dead.

                    Checked PQ5400 - AONS32314 and pins 5,6,7,8 are 20v (AC adaptor voltage) but pins 1, 2, 3, 4 are 0v.

                    Following Gate Pin 4 to PU5400 - BQ24780SRUYR.

                    VCC 20v
                    ACDET 2.8v
                    ACDRV 0v (goes to pin 4 gate of AONS32314).
                    ACOK 0v
                    REGN 6v

                    According to datasheet, conditions are correct for ACOK to be high but it is not.

                    Tracing ACOK it's connected to ACIN which is connected to a pin GPB0 of IT8227 but also shown as connected to +3VL via a 100k resistor...

                    The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
                    configurable for operating as either a Hybrid Power Boost (HPB)
                    charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
                    4-cell batteries. Both configurations allow the battery to work with
                    the adapter together to supply the system load when it exceeds
                    the adapter capability, referred to as system Turbo mode. HPB
                    charger configuration reverse-boosts battery energy to the system
                    bus to help the adapter provide the system power in Turbo mode.

                    Dell Inspiron 7567 LA-D993P odd charger issue
                    by Johndill
                    Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
                    There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
                    I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

                    Here are the tested scenarios:

                    1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

                    2. With the laptop off, plug in charger (LED says on) & the front charging...
