Hi friends my device is Asus K550J my laptop battery is blinking orange in both cases: with and without an AC adaptor.
Hi Soheil, This is what the indicator means according to Asus: The two-color LED provides a visual indication of the battery’s charge status.Refer to the following for details: Solid White : The Notebook PC is plugged to a power source and the battery power is between 95% and 100%.Solid Orange : The Notebook PC is plugged to a power source,charging its battery,and the battery power is less than 95%.Blinking Orange : The Notebook PC is running on battery mode and the battery power is less than 10%.Lights off : The Notebook PC is running on battery mode and the battery power is between 10% to 100%. I would try charging the notebook when it’s turned off and then check again. Do you use the original power supply that came with the notebook? Regards, Eelco
