    Hello. Tell me how to check the following chips: M92T36/BQ24193/P13USB. The console does not want to charge. With a new battery, I start the firmware, and error 2101-0001 appears

    Two things. 1. No. 2. Search the forums.

    in search gives out only guesses. "May be M92T36. May be BQ24193.replace everything" . I did not find the exact answer

    Additional information: all smd calls on one side only. Battery voltage 3.72V. 5 and 6 legs of the IC give out 2.76V
    In hekate, the battery charge does not jump (which, as I understand it, says that the BQ24193 is working

    3.72 = flat.

    First check something is getting into bq24193.

    Check testpoint on top of bq24193. V+ should be 0v without usb plugged.

    Rising to 3-4v usb plugged in.

    Next, check fuel gauge registers (max17050).

    The chip for this is on the other side of the board but you can check registers in Hekate (or fix/reprogram using my Hekate mod called switchboot) which has the disabled Hekate code enabled. Check registers aren't FF FF...

    If all is good and console is booting, then m92t36 is probably ok. Or at least the core voltage is. Pin 5 volts should = pin 6 +/- say 200mV. Though pin 5 can go higher up to 6v according to some Chinese users.

    Try this:

    On the ninty error screen, plug into dock. If you get picture, assume pi3usb is ok for now.

    That leaves bq24193 or fuel gauge(though this is just for battery percentages really).

    I'm not near my notes as I'm at the coast but will be home at end of week.

    w/ usb - 3.72
    yellow testpoint - always 0
    Switch in hekate:
    On green testpoint:
    without usb - 3.72
    w/ usb - 3.72
    yellow testpoint - always 0

    Docked - only green led on dock. No picture

    Do you get a picture with a charged battery?

    No volts with usb on yellow TP?

    Looking like bq24193 to me. Fuel gauge appears good.

    Got green light on dock...

    I'm saying bq24193 at the moment.

    The charge console shows the correct one. Threw to another - the same data. Ok then order bq24193. and it certainly can be connected with an error 2101-0001?

    Replace M92T36/BQ24193/P13USB.no effect. Consumption has become zero. It was 0.02A
    After replacing BQ24193, the voltage at the point where it used to be 0 became 0.05.
    After the replacement M92T36 сonsumption has become zero. Stopped turning on

    @mattytrog Please,help.
    Changed all 3 controllers. Consumption is also 0.03A. Now shows the wrong charge with any combination of controllers. Shows temperature normally.Comes in RCM. It does not load into the atmosphere, hangs on the logo. apparently due to battery readings. Could this be in case of a malfunction of the battery itself? Can it be checked somehow without another console?

    As it turned out, you can get into the RCM without M92T36

    I get to RCM mode by unpluging the NAND EMMC module, then press the power and plug it back in LOL

    also I leave you a little gift attached :)
