    Hi,

    All I know is that you have to have some sort of load to test it.
    Be it a light bulb, a Potentiometer or a laptop, you need a load.

    And the multimeter has to be connected in series and on the amps rating.

          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...

          Adaptable charger voltage for Clevo D901C laptop
          by HERETIK10
          Hello everyone,
          Thanks in advance to anyone who takes the time to help me. Sorry for the quality of my English, I had to use a translator at times...

          I bought a functional Clevo D901C (Sager NP 92261) with its battery but without its power supply.
          So, I invested in a new LiteOn charger, advertised by an online seller as the right charger for my machine... BUT, according to the pinout (4pin + shell) of the charger, 1 and 2 are 20V / and 3 and 4 are grounded. When I measure pin 4 with the ground of the PC, I have 300kOhms, which seems to be confirmed by the electrical...
