    If the resistance is too low, the mosfet is defective.

      Each looks to be low in resistance. Flux each and remove off the board.

      Then check the resistance again to confirm the resistance is consistent.

          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...
