    Asus Expertbook B9400CEA

    Hi,
    I found traces of liquid.
    RT8249CGQW (2N = **) and SY8288RAC (AWS **) faulty.
    Fix the traces of liquid and replaced the regulators, now it turns on perfectly both on battery and with power supply (usb-c) but does not charge the battery.
    The charger is Intersil 9241H.
    Unfortunately there is no motherboard diagram and I cannot find examples of connections with this charger. Can anyone suggest me a schematic motherboard with this charger?

              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...
