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... -
Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.

I have Lenovo ThinkPad X1 Nano Gen 1 which is not charging on 1 usbc port (the one that has mark for charging).
When i connect usb it switchs to 20v but no current draw (only 0.02a) and orang light is on. In windows it shows that is charging but percentage is dropping.
Other usbc is charging fine,
I installed lates bios and firmwares for thunderbolt and battery.

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.

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... -
