You get 5V at both USB-C connectors, connected in both directions (4 tests) Yes. Diode Mode: U3100 C3100 - 0.380 C3101 - 0.195 C3104 - 0.529 C3105 - 0.499 C3106 - 0.537 C3108 - 0.524 U3200 C3200 - 0.380 C3201 - 0.195 C3204 - 0.523 C3205 - 0.495 C3206 - 0.533 C3208 - 0.528 4) Inspect redriver...

TBA_AUX_DET = 1.3V (normal is 5V) that what a mean - Normal.

No liquid Damage and just stopped working. Here is some measurement: PPDCIM = 5.20V Drops to 4.7V (LOOP) TBA_AUX_DET = 1.3V (normal is 5V) PP3V3_G3H = Loop 3.4V and 3.2V after 2sec BUF_SMC_RESET_L =3.4V and 3.2V after 2sec SMC_BC_ACOK = 3.4V Diode Mode L7030 = 0.449 L6995 = 0.373 F7000 -...

Yes. What about the U3200 and U3100? Do you think the problem is just one ? What else can i look to make sure that is the real problem?

I replaced UB300 and i got 0.453 However, still doing the same thing: J3300 5.20V (Power Meter) On and OFF JB500 5.20V (Power Meter) Static PPBUS_G3H = 0 PP3V3_G3H = 3.4V goes to 3.3V after a two second and stay in loop

MB with no water damage, just stop work. Here is some measurements and i hope you guys can give me some direction. No short to ground on PPBUS_G3H Diode Mode (red prob to ground) ------- U3200 Powerline C3200 = 0.376 C3201 = 0.147 C3204 = 0.527 C3205 = 0.497 C3206 = 0.536 C3208 = 0.526...

PLT_RESET_L = Pulsing PPVCC_S0_CPU = Pulsing PP1V8_S3 = Pulsing no short to ground PP1V05_SUS = 1.05V The board had a liquid damage and cleaned properly. The liquid damage are was around U7400 and U7600. The bios was fine actually, but i can reprogram if that is the case. I will check the...

U1950 Pin 7 and 3 is Pulsing as well.

I'm sorry... PP3V3_S3 = Pulsing (0 to 3V) PM_SLP_S4_L = Pulsing I Did SMC bypass mode and nothing happen. PP5V_S5 = 5V PP3V3_S5 = 3.3V

PPBUS_G3H = 8.56V PPVRTC_G3H = 3.3V PP5V_S5 = 5V PP3V3_SUS - 3.3V PP3V3_S3 - 3.3V PP3V3_S5 - 3.3V PM_SLP_S3_L = PULSING PM_SLP_S4_L = PULSING WITHOUT FLEX CONNECTED PM_BATLOW_L = 3.3V PM_RSMRST_L = 3.3V PCH_DSWVRMEN = 3.23V PM_DSW_PWRGD = 3.4V I Trigged SMC_ONOFF_L and PM_PWRBTN_L and my...

L7670 (16.40 k ohm) and 7690 (10.45 k ohm) Gave me the same numbers in both sides. However, goes up and down and eventually stops. That's the only two Weird Big Coil. The rest of the big Coils gave me the measurement right way in both sides.

What you mean about "shorted high-side MOSFETs" ?

F7000 = 0.020 (diode mode w/ black probe at ground)

No liquid Damage. 20V however, no PPBUS L7030 = 0.03V - Diode Mode = 0.447 F7000 = 0.3V - Diode Mode = on ppbus side.072 PP3V3_G3H = 3.4V BUF_SMC_RESET_L = 3.4V TBA_AUX_DET = 5V SMC_BC_ACOK = 3.4V If i inject some Voltage on PPBUS_G3H, the CPU gets hot.

2informaticos 17/18 = 4.3 (supposed to be around 4) 27/28 = 21.7 (was supposed to be around 20) JohnB8812 SMC is pretty clean. I tested pins 10-11 ISL to SMC and is fine.

PPBUS_G3H: 12.56V PP5V_S0 = 5V PP3V_S0 = 3.3V PM_PWRBTN_L: 3.4V PM_RSMRST_L: 3.3V PM_PCH_PWROK: 0 no pulsing PM_PCH_SYS_PWROK: 0V PM_SYSRST_L: 3.3V PM_SLP_S5_L = 3.3V SMC_ADAPTER_EN 3.3V PM_SLP_SUS_L = 3.3V ALL_SYS_PWRGD = 0.23V NO PPVCORE_S0_CPU NO liquid damage

The Board is pretty clean. All the rails is there, however, the PPBUS_G3H is around 12.13V To low and don't detects the battery. Any hint?

I have question: The schematics shows on PP1V8 0SW DFR was supposed to get 1.8V, however, I'm getting 3.2V I thought the problem was the touch, but i replaced and the problem still. Any thoughts on that?

PP4V5_AUDIO_ANALOG = 0V I check and replaced already: U6200: Pin 6 = 5V Pin 1 = 0V Pin 4 = 3.3 (EN) HDA_RST_L 0V / 34K

Liquid Damage around U6201. I cleaned and re soldering all the U6201 pads. Also i replaced: L6202 C6220/22/13/14 R6210 I have 5V on Pin 46 I have 3.3V on Pin 1 I have 1.5V on Pin 9 Seems the U6201 could be bad, however, i'm not sure. Also is not recognized in the OS Any hint?
