    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.

    by peter99

    My laptop HP 245 AMD 14-FP5-6L -GDDR5X2 has a battery charging circuit error:
    - If not power on, battery charge ok.

    Lenovo g50-80 charging led flashing but laptop not switching on
    by B2L_Repairs
    I got a lenovo g50-80 that shows charging led (orange LED flashing) and when I press the power button the white LED comes on but the laptop doesn't switch on. The fan spins for 2 seconds when I press the power button then it stops. This problem started when my charging dock broke the connecting wires and i soldered these wires back but I might have mixed them. I ended up buying a new charging dock but laptop never switched on it just shows flashing orange LED when charger is connected. Could the super io be bad? I don't know how to go about diagnosing and I can't check any board view since this...
