    iPhone XS not charging

    The cables and lighting port chargers did not help.
    Current consumption from the charger is 0,00A
    PC not reconize Iphone
    Iphone work if have battery is charged.
    I found short circuit on the lighting flex socket of the motherboard on pin 14 (PMU_TO_PHALANX2) and pin 17 (PMU_TO_PHALANX1).
    And pin 20 (MIKEYBUS_REFERENCE) 100 Ω.
    pin 24 (90_HYDRA_DP2_CONN_P ) pin 26 (90_HYDRA_DP2_CONN_N) pin 28 (90_HYDRA_DP1_CONN_P) and 30 (90_HYDRA_DP1_CONN_N) its OK
    Need replace U2700 ?

        Hello,


        Pin 14 and 17 on J6400 are ground pin it's not a short.
        Connect a charger and check PP_VBUS1_E75 (TP0773) you should have 5V.
        If it's ok you have to separate the motherboard and check value in diode mode around U3300.

              I have 5V on B242.
              Need 100% separate to continue ? or maybe U6300 (hydra) change?

                no, this is a blind way.
                Desolder a sandwich and check again everything from PP_BAT way to VDD_Main. You have to have a some schematic diagram, boardview should be enough.

                  ASUS X54H laptop thinks it's always charging even with charger unplugged
                  by flat-earther
                  The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

                  Windows also shows ''Plugged in'' when charger is not connected.

                  This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
                  Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
                  If I let battery run out and say it has 3% Windows will...

                  HP Probook 470 G4 - Power and Charging Problem
                  by Scoff
                  Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
                  Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

                  by SluggerB
                  I have two TCL A30 phones.

                  Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

                  New Phone: Works fine, bought as a donor board to try and repair Old Phone

                  My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

                  iPhone X not charging
                  by Nash99
                  Hi everyone

                  I replaced a battery fpc connector on an iPhone X. The process went well and the connector is connected securely. However, the iPhone is not charging. It powers on, however it does not show the lightning bolt when plugged in and the battery percentage is at a constant 0%. It was charging fine before the replacement. It still, however, makes the charging sound when it is plugged in and connects to a computer fine. What should I do? What can be causing this?

                  Also, I have attached a picture, please can some help identity what these two components are and what...
