    R6906 0.28 Do I measure the D6905 with black to ground? If these are the values: Pin 1 3.7 M ohm (it is worth very unstable) Pin 2 118k ohm Pin 3 0.427k ohm

    820-00840-A no power only 5V on PP20

    I corrected my previous post, I had done the measurements with the power supply connected. If there is a need to remove them from the board I will do it, it's not very clear to me, sorry

    820-00840-A no power only 5V on PP20

    The problem occurred suddenly while the computer was on, it shut down and from there no sign of life. Original charger. Tomorrow I'll try to take other measurements, I don't have a good board for the values...

    820-00840-A no power only 5V on PP20

    hi everyone, logic board with no sign of liquid, no ignition, I receive 5 V on the PP20V_USBC line but nothing on the PP3V3_G3H line

    Sorry, I didn't see the answer and I had updated my previous post, with the new capacitor everything worked! Thanks for the support 🤝😊

    820-01958 only 5V no power

    yes, I had already dedicated myself to this resistor, with the tester measuring 0.18 ohm. 3V3_G3H_RTC is 0V but I didn't replace C6961, I diden't know if this could be the cause even if I see that it is a capacitor connected in parallel to others. Update: I soldered a new capacitor and it works...

    820-01958 only 5V no power

    All 0V, I corrected the back post above because I didn't remember the names of the lines I had checked. I think the problem could be U7000 but I'm waiting for your expert opinion.

    820-01958 only 5V no power

    No 12V, no 3V, all the lines don't seem to be powered Could the U7000 be faulty? PPBUS_G3H I have 0V
