    resolved. I noticed that ppbus_g3h with the battery connected went to fuse F7000, that was fine. Analyzing the i2c lines of the battery I see that they feed on pp3v3_g3h. This voltage comes out of ic U6990. When I measure the input voltage which is PPVIN_G3H_P3V3G3H I see that there is no...

    there is continuity between its lines. C7020 voltages is 13.04v on both sides. C7023 voltage is 14.77 on both sides.

    that's right, 12.28V diode mode SDA: 427 SCL: 427 With charger PPBUS_G3H it is 13.04V SDA: 3.37V SCL: 3.37V When I connect the battery flex, the usb c meter restarts.

    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...

    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

    Already compare with another plate of the same number. And those voltages are present

    exactly. the machine turns on but stays in the progress bar. To my bad luck I don't have another board to test, but I'm pretty sure those voltages are missing. At least one.

    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.

    resolved. Note that the machine when closing the screen did not return the image and turned off. Check lined SMC_LID 3.3V resistors good. Value in Diode pin 2 of the resistor 5252 value 2.293 abnormal. Compared to another plate the value was 0.478 I had to make a jumper and the value...

    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...

    A1990 AmrestoreErrorDomin Error-9 trying to restore with configurator 2

    error 9 is related to the power supply of the ssd or the bad ssd. Very common in that model.
