    820-01041 No S5

    My reference only: TT10189 Problem: liquid damage, does not turn on even though USBC meter shows 20v. Work done so far: C9589 had a short and was replaced. CHGR_BGATE has 12v but is unstable, it drops to 4v then back up to 12v. I have already replaced U7000, I also removed all the capacitors on...

    820-02100 Mosfet where to purchase?

    Ordered, thank you very much!

    Sorry I am just now getting back to you on this. I normally document these with a ticket number but this one I did not. Must have been before I started doing that. I vaguely remember this but It may have been something I did a manual DFU on by pulling up the pads to 1.8v. Could not say for 100%...

    820-02100 Mosfet where to purchase?

    My reference only: TT10141. Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this...

    820-02100 M1 Pro Coffee spill

    I think U9300 could be a culprit. I removed it and USB-c was read 5v, but PPVIN_P1V8VDDH_CTRL_VIN was stable at the 12v having removed U9300. Got U9300 back on and I am getting the same reboot looping. Testing R9330 and it seems a little low 1.195v to 0v looping. What exactly does the Viper...

    820-02100 M1 Pro Coffee spill

    My reference only: TT10141 History: Coffee spill. Lot of damage around UP800, U9300. There is a lug at the bottom left corner of resistor RP860 that is missing. No documentation on what this is for. Q5240 had looked like it had damage. Current issue: I plug in the USB-C meter, it goes to the...

    Sure, can you send me the original link where this conversation took place so I can look it up?

    820-02098 Stuck at 5v

    P3V8AON_VSW1 is now at .356 diode mode! P0V9_LX0_NAND0 is .286 should be .310. P0V9_LX1_NAND0 is .291 should be .310. P1V2_LX0_NAND0 is .004 should be .306, looks like we got a problem here. Glad you told me to check the coils. I removed LN430 and the short is on pin 2 or on PP1V2_NAND0.

    820-02098 Stuck at 5v

    UN400 seems to be getting hot from voltage injection in to P3V8AON_VSW1. Q5840/20/00 I removed because all these were getting hot too. I took those off one by one and now UN400 is suspect. I originally looked at this board thinking something could be going on with the SSD. What dio you think? I...

    820-02098 Stuck at 5v

    QC280 had a short! I am getting consistent pulling of .44 amps now wheas I was only getting the amps pulled for the first few minutes and it would drop to 0 amps. Pins 6 on QC280 which is P5VS2_DSCHG is getting 1.96v while plugged in. I had removed both C5701 and C5702 as they both looked a...

    820-02098 Stuck at 5v

    P3V8AON_SW3 diode mode is 2.278 P3V8AON_SW2 diode mode is 2.278 Q5840, Q5820, L5840, L5820, and R5800 are currently lifted with the above readings. In addition, L5800 is now lifted too, P3V8AON_VSW1 is .490 diode, .PP3V8AON_PH1 diode is .056. Everything keeps pointing back to PP3V8_AON like you...

    820-02098 Stuck at 5v

    I did try removing practically everything on 3V8_AON and nothing went high. When I removed Q5800, pin 3 went high in diode mode being 2.125.

    Diode mode shows pin 1 @ .053 pin 2 shows @ .770.

    820-02098 Stuck at 5v

    Thank you. I have not put back U8100 yet but poking around P3V8AON_VSENSE diode mode reading is .05, should be .356. What is this sensing? I keep coming back to this area too but NOSTUFF is in this area.

    820-02098 Stuck at 5v

    Okay, let me bounce this off you then if I may. Since I removed U8100, the up and down voltage on L5800 pad 1 is now for the most part stable at 3.9v. This may be because of removing U8100? However in the process, I knocked a few other components around U8100 off. So I will be cleaning the area...
