    ASUS UX31 not work on battery

    Hi all,
    I have problem with this laptop. Works normally on charger but not work with battery. Battery isn't detected in windows - new battery. Battery connector was damaged, I resolder all pins, but pins 4,5,6 aren't connected to PCB because of pads are lifted from board.. I mean my laptop should work on battery, other pins + and GND are ok, maybe there be problems with charging..

    After PQ8803 I have battery voltage, I tried replace charger IC BQ24725a. Still the same.Can someone help me with this? And have someone the Boardview? thanks.

    I attached measurement on charger IC with charger and battery connected.

      Run jumper wires from the connector to the associated resistors.

              What motherboard version ?
              The resistors you are searching are in bottom layer

                          Highly Integrated Narrow VDC Battery Charger for Notebook Computers

                          The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
                          for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
                          Narrow VDC applications where the system power source is
                          either the battery pack or the regulated output of the charger.
                          This makes the max voltage to the system equal to the max
                          battery voltage instead of the max adapter voltage. Operating
                          at lower system voltage can improve...

                          ASUS X571 no power : battery issue?
                          by mkdj
                          Hello everyone,

                          Mark and model: ASUS X571
                          Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

                          Tests already made:
                          - Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
                          - I have removed...

                          how to prevent a connected charger from draining battery when not charging?
                          by flat-earther
                          I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.
                          So to improve it, I added a 15W USB-C charger board(link) inside and soldered it to the same connector on the PCB where the battery plugs into, great, now I can simply charge it with a USB-C cable.

                          but the problem I found is that after the radio sat for two weeks without being used the 2S 18650 battery that I'm using was at 4.2V!
                          So the battery is backfeeding the charger and being drained.

                          How can I prevent...

                          Bauer tool battery pack charging with a HERCULES charger modification
                          by sam_sam_sam
                          The Bauer power tool battery charger just has to many issues with the charger over heating because I several HERCULES Hercules battery chargers that are 3 amp charge and because they have gone on quite a few times over the years before they came out with the fan cooling battery charger I going to modify one so I can charge Bauer battery packs faster than the crape battery charger that they have

                          Here is how this modification is going to be done I taking a 1.5 amp hour battery enclosure and gutting it removing the battery cells and replacing some Ryobi 1.5 amp hour battery pack that...
