        Change Or check Power adapter ,(using bench power supply Instead of adapter )
        Download Schematic And check Charger IC And Components (Mosfets , Caps , Fuse ,...)
        Check Voltage On Charger IC

              it's easy to change one mosfet, but it's difficult to change charging ic, my answer was based on my proper experience, because i have repaired two laptop with the same problem (platform scal 2 and scala 3)

                      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.
                      ...
