hello everyone. This board does not detect voltage when connecting the battery. already ruled out battery. when connecting the 87 watt cable, PPBUS is 12.56V the voltage on the PPVBAT_G3H_CONN line is 12.57Volts then it drops to 168mv, it's as if it were looking for the battery. i2c battery...

Hi everyone. This machine when I disconnect the flex from the battery, it generates 20V and turns on. The machine has a problem that the touch bar works but does not show an image. suggestions? Thank you!

Hello everyone, this model has a consumption of 1,200 amps. It doesn't turn on, it arrived because it didn't detect the hard drive... The machine cycles on from 0.0013 amps then rises to 0.900 amps and then drops to 0.0013 amps. This plate makes a cycle of 3 ignitions... who is in charge of...

This team tells me the client that it was turned off out of nowhere. PPBUS_G3H 13.05V CPU voltages, PPVCCCPU_S0G is 0.95 then drops to 0.66v. There is no startup sound. PM_PCH_PWROK and PM_PCH_SYS_PWROK present with 2.96V AP_RESET_L 3.0V PLT_RST_L 3.31V RAM voltages present. I don't know...

Hi everyone. I have an a1707 that does not detect an accessory such as usb c to hdmi through the J3300 port, normal charging in both ports on both sides. In the JB500 connector it works perfectly. I already changed U2800 U3100 U3200

I have this machine that takes time to turn on, I already reprogrammed bios and format but still the problem continues. When the machine is in sleep and you press any key to bring up the image, it freezes and reboots, "displaying a screen in three languages and Chinese letters" Inspecting the...

Hi everyone. This macbook does not work the keyboard illuminator, I see that in the system preferences it does not detect it. I tried another plate of the same model 820-01521 in the case and if it is detected by the lighting in the system preferences and when I press the keys it lowers and...

Any suggestions for this error? It comes intervened from another workshop. the machine turns on normally, but halfway through when the apple comes out, spots appear on the color screen, take the image externally to a monitor and it's the same problem. When moving the cursors and opening...

This plate is intervened from another workshop. I don't have ppbus_g3h. I already changed U7000 it has 5v in usb c test. Present voltages: PP3V3_G3H The cd3215 has its ldo except u3100 and u3200 does not have PP1V1_UPC_XA_LDO_BMC

It has a volume icon in the system, at the time of raising or lowering the volume it is gray. I tried with another system and it has the same symptom. change u6201 and the same. pp4v5_audio_analog 4.45V PP3V3_S0_AUDIO_ANALOG 3.3V PP1V5_S0_AUDIO_DIG_FILT 1.5V i'm thinking it may be some of...

Hi everyone. I have this plaque, liquid drop. Coffee. The machine has 20V and consumption of 500ma. I have ALL_SYS_PWRGD I have CPU voltages I am missing PPVCCEDRAM_S0_CPU. This voltage comes out of U7710, the activation PVCCEDRAMS0_EN_FILT_BUF I'm missing, it comes from U7712. U7712 would...

Hi everyone. I have seen this fault before in models 820-00165. The problem is the following, I don't have ALL_SYS_PWRGD, when removing u1950 the machine turns on but obviously not completely because PM_PCH_SYS_PWROK is missing. My question is, how do I attack this bug? Would I have to change...

This board came from another service, they repaired it and changed the U7100 but it turns off after power on. I changed U7100 to discard but now it stays at 20V and 267 ma. PPVCCCPU_S0G is 0V. I have ALL_SYS_PWRGD 3.2v CPUVR_PWM2 2.49V CPUVR_PWM1 2.49V I am missing PM_PCH_SYS_PWROK

Greetings to all. This machine does not have pp3v3_s5. Voltajes en U7600 Pin 12: PM_EN_FET_P12V_S5_SSD (3.41V) Pin 24: PM_EN_REG_P5V_S4_R (0.00) PIN 17: PP12V_S5_FET_P3V3_S5_P5V_S4 (12.0V) PIN 4 y 5: 0V Pin 5 y 4 it's an LDO which is generated by the same u7600. I changed it a couple of...

Hello, greetings to all. This plate got liquid on it. The problem is that it does not recognize the battery, it only turns on with the charger. When connecting the battery the voltage on ppbus_g3h is 12.28V. SDA line 0v SCL line 0v When only the charger is connected without the battery...

this board has all the voltages including the VCORE, but it does not show an image. When it is connected to the source it reaches a consumption of 0.800 ma then it rises to 1.040 am little by little. my question, what should I check in these models. I understand that it could be the PCH...

This machine reaches a consumption of 0.683 in the fixed source. spin the fan. PPBUS_G3H 12.57V PPVCORE_S0_CPU 0.99V PPVCORE_S0_MCP 0.925V I realize that U6100 1: 3.3V 2: 0.20mv 3: 3.28V 4: gnd 5:000.0 6:000.0 7: 2.93v 8: 3.3v

Hello everyone. This machine does not pick up 20V, it stays at 5v and then turns off and restarts at 5v. PPBUS_G3H is 022.4mv

Hello everyone. I have this motherboard that takes time to turn on. I suspect it may be bios. U6100 voltages 1: 3.3v 2: 3.2v 3: 3.3v 4:GND 5: 0.56mv 6: 000.1mv 7: 3.3V 8: 3.3V My question is, are these values ok? I haven't tried another bios yet.

Hello everyone. I have this plate that turns on but when it turns off after a while, it no longer turns on. I have to disconnect the battery and then it turns on. PPBUS_G3H voltage is 12.10V with battery connected. With the 87W cable connected, the PPBUS_G3H voltage goes up to 12.70V...
