      It's a typical problem, actually. Something wrong with the charger circuit.

      Please identify the board correctly.

              Stop guessing, debug the circuit.

                          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...

                          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
                          by serious_electron
                          Hello Everyone!

                          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.                          ...

                          -& it also works when plugged in battery & charger, but it's not charging the battery
                          //Confirming, i have same issue, but problem started from charger, centre PIN is outputing 10V+ and jumping randomly 19V

                          Acer Nitro 5 AN515-45 not charging
                          by CPUFiddler
                          Hi there. I am trying to repair an Acer Nitro 5 AN515-45 and it's giving me some trouble. I have access to SMD rework station, variable power supply, digital oscilloscope, thermal camera, multimeter, stereo microscope.
                          This laptop will boot and run from the power brick and/or the internal battery, but it will not charge the battery. NirSoft BattInfo tells me the charge/discharge currents, so I'm confident in saying that it's not charging. In addition, there's no increase in voltage at the battery connector when the laptop thinks it's charging, not even a few millivolts.
